Detailed Description
Represents a texture object, which is typically a single 2-d image but may also represent a 1-d or 3-d texture image, or the six 2-d faces of a cube map texture.
A texture's image data might be stored in system RAM (see get_ram_image()) or its image may be represented in texture memory on one or more GraphicsStateGuardians (see prepare()), or both. The typical usage pattern is that a texture is loaded from an image file on disk, which copies its image data into system RAM; then the first time the texture is rendered its image data is copied to texture memory (actually, to the graphics API), and the system RAM image is automatically freed.
Constructor & Destructor Documentation
◆ Texture()
|
explicit |
Constructs an empty texture.
The default is to set up the texture as an empty 2-d texture; follow up with one of the variants of setup_texture() if this is not what you want.
Definition at line 374 of file texture.cxx.
Referenced by PT().
Member Function Documentation
◆ adjust_size()
|
static |
Computes the proper size of the texture, based on the original size, the filename, and the resizing whims of the config file.
x_size and y_size should be loaded with the texture image's original size on disk. On return, they will be loaded with the texture's in-memory target size. The return value is true if the size has been adjusted, or false if it is the same.
Definition at line 2640 of file texture.cxx.
Referenced by consider_rescale().
◆ adjust_this_size()
|
inline |
Works like adjust_size, but also considers the texture class.
Movie textures, for instance, always pad outwards, regardless of textures- power-2.
Definition at line 2154 of file texture.I.
Referenced by MovieVideoCursor::setup_texture().
◆ clear_image()
|
inline |
Clears the texture data without changing its format or resolution.
The texture is cleared on both the graphics hardware and from RAM, unlike clear_ram_image, which only removes the data from RAM.
If a clear color has been specified using set_clear_color, the texture will be cleared using a solid color.
The texture data will be cleared the first time in which the texture is used after this method is called.
◆ clear_ram_image()
|
inline |
Discards the current system-RAM image.
Definition at line 1439 of file texture.I.
Referenced by GraphicsOutput::add_render_texture().
◆ clear_ram_mipmap_image()
| void Texture::clear_ram_mipmap_image | ( | int | n | ) |
Discards the current system-RAM image for the nth mipmap level.
Definition at line 1271 of file texture.cxx.
◆ clear_ram_mipmap_images()
|
inline |
◆ clear_simple_ram_image()
|
inline |
◆ compress_ram_image()
|
inline |
Attempts to compress the texture's RAM image internally, to a format supported by the indicated GSG.
In order for this to work, the squish library must have been compiled into Panda.
If compression is CM_on, then an appropriate compression method that is supported by the indicated GSG is automatically chosen. If the GSG pointer is NULL, any of the standard DXT1/3/5 compression methods will be used, regardless of whether it is supported.
If compression is any specific compression method, that method is used regardless of whether the GSG supports it.
quality_level determines the speed/quality tradeoff of the compression. If it is QL_default, the texture's own quality_level parameter is used.
Returns true if successful, false otherwise.
◆ consider_rescale() [1/2]
| void Texture::consider_rescale | ( | PNMImage & | pnmimage | ) |
Asks the PNMImage to change its scale when it reads the image, according to the whims of the Config.prc file.
For most efficient results, this method should be called after pnmimage.read_header() has been called, but before pnmimage.read(). This method may also be called after pnmimage.read(), i.e. when the pnmimage is already loaded; in this case it will rescale the image on the spot. Also see rescale_texture().
Definition at line 2014 of file texture.cxx.
References get_auto_texture_scale.
◆ consider_rescale() [2/2]
|
static |
Asks the PNMImage to change its scale when it reads the image, according to the whims of the Config.prc file.
For most efficient results, this method should be called after pnmimage.read_header() has been called, but before pnmimage.read(). This method may also be called after pnmimage.read(), i.e. when the pnmimage is already loaded; in this case it will rescale the image on the spot. Also see rescale_texture().

◆ cull_callback()
|
virtual |
If has_cull_callback() returns true, this function will be called during the cull traversal to perform any additional operations that should be performed at cull time.
This is called each time the Texture is discovered applied to a Geom in the traversal. It should return true if the Geom is visible, false if it should be omitted.
Reimplemented in VideoTexture.
Definition at line 2529 of file texture.cxx.
◆ down_to_power_2()
|
static |
Returns the largest power of 2 less than or equal to value.
Definition at line 1995 of file texture.cxx.
References get_next_higher_bit().
◆ ensure_loader_type()
|
virtual |
May be called prior to calling read_txo() or any bam-related Texture- creating callback, to ensure that the proper dynamic libraries for a Texture of the current class type, and the indicated filename, have been already loaded.
This is a low-level function that should not normally need to be called directly by the user.
Note that for best results you must first create a Texture object of the appropriate class type for your filename, for instance with TexturePool::make_texture().
Definition at line 2750 of file texture.cxx.
◆ estimate_texture_memory()
| size_t Texture::estimate_texture_memory | ( | ) | const |
Estimates the amount of texture memory that will be consumed by loading this texture.
This returns a value that is not specific to any particular graphics card or driver; it tries to make a reasonable assumption about how a driver will load the texture. It does not account for texture compression or anything fancy. This is mainly useful for debugging and reporting purposes.
Returns a value in bytes.
Definition at line 675 of file texture.cxx.
References uses_mipmaps().
◆ finalize()
|
virtual |
Called by the BamReader to perform any final actions needed for setting up the object after all objects have been read and all pointers have been completed.
Reimplemented from TypedWritable.
Definition at line 9858 of file texture.cxx.
References ReferenceCount::unref().
◆ format_component_type()
|
static |
Returns the indicated ComponentType converted to a string word.
Definition at line 2104 of file texture.cxx.
◆ format_compression_mode()

static |
Returns the indicated CompressionMode converted to a string word.

◆ format_quality_level()
|
static |
Returns the indicated QualityLevel converted to a string word.
Definition at line 2446 of file texture.cxx.
◆ format_texture_type()
|
static |
Returns the indicated TextureType converted to a string word.
Definition at line 2052 of file texture.cxx.
◆ generate_alpha_scale_map()
| void Texture::generate_alpha_scale_map | ( | ) |
Generates a special 256x1 1-d texture that can be used to apply an arbitrary alpha scale to objects by judicious use of texture matrix.
The texture is a gradient, with an alpha of 0 on the left (U = 0), and 255 on the right (U = 1).
Definition at line 526 of file texture.cxx.
◆ generate_normalization_cube_map()
| void Texture::generate_normalization_cube_map | ( | int | size | ) |
Generates a special cube map image in the texture that can be used to apply bump mapping effects: for each texel in the cube map that is indexed by the 3-d texture coordinates (x, y, z), the resulting value is the normalized vector (x, y, z) (compressed from -1..1 into 0..1).
Definition at line 424 of file texture.cxx.
◆ generate_ram_mipmap_images()
|
inline |
Automatically fills in the n mipmap levels of the Texture, based on the texture's source image.
This requires the texture's uncompressed ram image to be available in system memory. If it is not already, it will be fetched if possible.
This call is not normally necessary, since the mipmap levels will be generated automatically if needed. But there may be certain cases in which you would like to call this explicitly.
◆ generate_simple_ram_image()
| void Texture::generate_simple_ram_image | ( | ) |
Computes the "simple" ram image by loading the main RAM image, if it is not already available, and reducing it to 16x16 or smaller.
This may be an expensive operation.
Definition at line 1318 of file texture.cxx.
◆ get_active()
| bool Texture::get_active | ( | PreparedGraphicsObjects * | prepared_objects | ) | const |
Returns true if this Texture was rendered in the most recent frame within the indicated GSG.
Definition at line 1513 of file texture.cxx.

◆ get_clear_data()
|
inline |
◆ get_data_size_bytes()
| size_t Texture::get_data_size_bytes | ( | PreparedGraphicsObjects * | prepared_objects | ) | const |
Returns the number of bytes which the texture is reported to consume within graphics memory, for the indicated GSG.
This may return a nonzero value even if the texture is not currently resident; you should also check get_resident() if you want to know how much space the texture is actually consuming right now.
Definition at line 1486 of file texture.cxx.

Returns the total number of pages that the nth mipmap level should have, based on the texture's size.
This is usually the same as get_expected_mipmap_z_size(), except for a multiview texture, in which case it is get_expected_mipmap_z_size() * get_num_views().

◆ get_ram_image()

inline |
Returns the system-RAM image data associated with the texture.
If the texture does not currently have an associated RAM image, and the texture was generated by loading an image from a disk file (the most common case), this forces the reload of the same texture. This can happen if keep_texture_ram is configured to false, and we have previously prepared this texture with a GSG.
Note that it is not correct to call has_ram_image() first to test whether this function will fail. A false return value from has_ram_image() indicates only that get_ram_image() may need to reload the texture from disk, which it will do automatically. However, you can call might_have_ram_image(), which will return true if the ram image exists, or there is a reasonable reason to believe it can be loaded.
On the other hand, it is possible that the texture cannot be found on disk or is otherwise unavailable. If that happens, this function will return NULL. There is no way to predict with 100% accuracy whether get_ram_image() will return NULL without calling it first; might_have_ram_image() is the closest.
◆ get_ram_image_as()
| CPTA_uchar Texture::get_ram_image_as | ( | const std::string & | requested_format | ) |
Returns the uncompressed system-RAM image data associated with the texture.
Rather than just returning a pointer to the data, like get_uncompressed_ram_image, this function first processes the data and reorders the components using the specified format string, and places these into a new char array.
The 'format' argument should specify in which order the components of the texture must be. For example, valid format strings are "RGBA", "GA", "ABRG" or "AAA". A component can also be written as "0" or "1", which means an empty/black or a full/white channel, respectively.
This function is particularly useful to copy an image in-memory to a different library (for example, PIL or wxWidgets) that require a different component order than Panda's internal format, BGRA. Note, however, that this conversion can still be too slow if you want to do it every frame, and should thus be avoided for that purpose.
The only requirement for the reordering is that an uncompressed image must be available. If the RAM image is compressed, it will attempt to re-load the texture from disk, if it doesn't find an uncompressed image there, it will return NULL.

◆ get_ram_mipmap_page_size()

inline |
Returns the number of bytes used by the in-memory image per page for mipmap level n, or 0 if there is no in-memory image for this mipmap level.
For a non-compressed texture, this is the same as get_expected_ram_mipmap_page_size(). For a compressed texture, this may be a smaller value. (We do assume that all pages will be the same size on a compressed texture).
◆ get_ram_mipmap_pointer()
| void * Texture::get_ram_mipmap_pointer | ( | int | n | ) | const |
Similiar to get_ram_mipmap_image(), however, in this case the void pointer for the given ram image is returned.
This will be NULL unless it has been explicitly set.
Definition at line 1222 of file texture.cxx.
◆ get_ram_mipmap_view_size()
|
inline |
Returns the number of bytes used by the in-memory image per view for mipmap level n, or 0 if there is no in-memory image for this mipmap level.
A "view" is a collection of z_size pages for each mipmap level. Most textures have only one view, except for multiview or stereo textures.
For a non-compressed texture, this is the same as get_expected_ram_mipmap_view_size(). For a compressed texture, this may be a smaller value. (We do assume that all pages will be the same size on a compressed texture).
◆ get_resident()

◆ get_tex_scale()
|
inline |
Returns a scale pair that is suitable for applying to geometry via NodePath::set_tex_scale(), which will convert texture coordinates on the geometry from the range 0..1 into the appropriate range to render the video part of the texture.
This is necessary only if a padding size has been set via set_pad_size() (or implicitly via something like "textures-power-2 pad" in the config.prc file). In this case, this is a convenient way to generate UV's that reflect the built-in padding size.

◆ get_uncompressed_ram_image()
|
inline |
Returns the system-RAM image associated with the texture, in an uncompressed form if at all possible.
If get_ram_image_compression() is CM_off, then the system-RAM image is already uncompressed, and this returns the same thing as get_ram_image().
If get_ram_image_compression() is anything else, then the system-RAM image is compressed. In this case, the image will be reloaded from the *original* file (not from the cache), in the hopes that an uncompressed image will be found there.
If an uncompressed image cannot be found, returns NULL.

◆ has_ram_image()
|
inline |
Returns true if the Texture has its image contents available in main RAM, false if it exists only in texture memory or in the prepared GSG context.
Note that this has nothing to do with whether get_ram_image() will fail or not. Even if has_ram_image() returns false, get_ram_image() may still return a valid RAM image, because get_ram_image() will automatically load the texture from disk if necessary. The only thing has_ram_image() tells you is whether the texture is available right now without hitting the disk first.
Note also that if an application uses only one GSG, it may appear that has_ram_image() returns true if the texture has not yet been loaded by the GSG, but this correlation is not true in general and should not be depended on. Specifically, if an application ever uses multiple GSG's in its lifetime (for instance, by opening more than one window, or by closing its window and opening another one later), then has_ram_image() may well return false on textures that have never been loaded on the current GSG.

| BamCacheRecord * | record = nullptr, |
||
| const LoaderOptions & | options = LoaderOptions() |
||
| ) |
Reads the texture from the indicated filename.
If primary_file_num_channels is not 0, it specifies the number of components to downgrade the image to if it is greater than this number.
If the filename has the extension .txo, this implicitly reads a texture object instead of a filename (which replaces all of the texture properties). In this case, all the rest of the parameters are ignored, and the filename should not contain any hash marks; just the one named file will be read, since a single .txo file can contain all pages and mipmaps necessary to define a texture.
If alpha_fullpath is not empty, it specifies the name of a file from which to retrieve the alpha. In this case, alpha_file_channel represents the numeric channel of this image file to use as the resulting texture's alpha channel; usually, this is 0 to indicate the grayscale combination of r, g, b; or it may be a one-based channel number, e.g. 1 for the red channel, 2 for the green channel, and so on.
If read pages is false, then z indicates the page number into which this image will be assigned. Normally this is 0 for the first (or only) page of the texture. 3-D textures have one page for each level of depth, and cube map textures always have six pages.
If read_pages is true, multiple images will be read at once, one for each page of a cube map or a 3-D texture. In this case, the filename should contain a sequence of one or more hash marks ("#") which will be filled in with the z value of each page, zero-based. In this case, the z parameter indicates the maximum z value that will be loaded, or 0 to load all filenames that exist.
If read_mipmaps is false, then n indicates the mipmap level to which this image will be assigned. Normally this is 0 for the base texture image, but it is possible to load custom mipmap levels into the later images. After the base texture image is loaded (thus defining the size of the texture), you can call get_expected_num_mipmap_levels() to determine the maximum sensible value for n.
If read_mipmaps is true, multiple images will be read as above, but this time the images represent the different mipmap levels of the texture image. In this case, the n parameter indicates the maximum n value that will be loaded, or 0 to load all filenames that exist (up to the expected number of mipmap levels).
If both read_pages and read_mipmaps is true, then both sequences will be read; the filename should contain two sequences of hash marks, separated by some character such as a hyphen, underscore, or dot. The first hash mark sequence will be filled in with the mipmap level, while the second hash mark sequence will be the page index.
This method implicitly sets keep_ram_image to false.

This method is called by the GraphicsEngine at the beginning of the frame *after* a texture has been successfully uploaded to graphics memory.
It is intended as a callback so the texture can release its RAM image, if _keep_ram_image is false.
This is called indirectly when the GSG calls GraphicsEngine::texture_uploaded().

◆ write() [1/3]
|
inline |
◆ write() [2/3]
|
inline |
Writes a single page or mipmap level to a single file, or automatically writes a series of pages and/or mipmap levels to a numbered series of files.
If the filename ends in the extension .txo, this implicitly writes a Panda texture object (.txo) instead of an image file. In this case, the remaining parameters are ignored, and only one file is written, which will contain all of the pages and resident mipmap levels in the texture.
If write_pages is false, then z indicates the page number to write. 3-D textures have one page number for each level of depth; cube maps have six pages number 0 through 5. Other kinds of textures have only one page, numbered 0. If there are multiple views, the range of z is increased; the total range is [0, get_num_pages()).
If write_pages is true, then all pages of the texture will be written. In this case z is ignored, and the filename should contain a sequence of hash marks ("#") which will be filled in with the page index number.
If write_mipmaps is false, then n indicates the mipmap level number to write. Normally, this is 0, for the base texture image. Normally, the mipmap levels of a texture are not available in RAM (they are generated automatically by the graphics card). However, if you have the mipmap levels available, for instance because you called generate_ram_mipmap_images() to generate them internally, or you called GraphicsEngine::extract_texture_data() to retrieve them from the graphics card, then you may write out each mipmap level with this parameter.
If write_mipmaps is true, then all mipmap levels of the texture will be written. In this case n is ignored, and the filename should contain a sequence of hash marks ("#") which will be filled in with the mipmap level number.
If both write_pages and write_mipmaps is true, then all pages and all mipmap levels will be written. In this case, the filename should contain two different sequences of hash marks, separated by a character such as a hyphen, underscore, or dot. The first hash mark sequence will be filled in with the mipmap level, while the second hash mark sequence will be the page index.

◆ get_num_loadable_ram_mipmap_images
| int Texture::get_num_loadable_ram_mipmap_images |
Returns the number of contiguous mipmap levels that exist in RAM, up until the first gap in the sequence.
It is guaranteed that at least mipmap levels [0, get_num_ram_mipmap_images()) exist.
The number returned will never exceed the number of required mipmap images based on the size of the texture and its filter mode.
This method is different from get_num_ram_mipmap_images() in that it returns only the number of mipmap levels that can actually be usefully loaded, regardless of the actual number that may be stored.
◆ get_num_pages
|
inline |
Returns the total number of pages in the texture.
Each "page" is a 2-d texture image within the larger image–a face of a cube map, or a level of a 3-d texture. Normally, get_num_pages() is the same as get_z_size(). However, in a multiview texture, this returns get_z_size() * get_num_views().
◆ get_num_ram_mipmap_images
|
inline |
Returns the maximum number of mipmap level images available in system memory.
The actual number may be less than this (that is, there might be gaps in the sequence); use has_ram_mipmap_image() to verify each level.
Also see get_num_loadable_ram_mipmap_images().
◆ get_num_views
|
inline |
Returns the number of "views" in the texture.
A view is a completely separate image stored within the Texture object. Most textures have only one view, but a stereo texture, for instance, may have two views, a left and a right image. Other uses for multiple views are not yet defined.
If this value is greater than one, the additional views are accessed as additional pages beyond get_z_size().

Returns the current quality_level hint.
See set_quality_level(). This value may return QL_default; see get_effective_quality_level().
◆ get_ram_image_compression
|
inline |
Returns the compression mode in which the ram image is already stored pre- compressed.
If this is other than CM_off, you cannot rely on the contents of the ram image to be anything predicatable (it will not be an array of x by y pixels, and it probably won't have the same length as get_expected_ram_image_size()).

◆ get_ram_image_size
|
inline |
◆ get_ram_page_size
|
inline |
Returns the number of bytes used by the in-memory image per page, or 0 if there is no in-memory image.
For a non-compressed texture, this is the same as get_expected_ram_page_size(). For a compressed texture, this may be a smaller value. (We do assume that all pages will be the same size on a compressed texture).
◆ get_ram_view_size
|
inline |
Returns the number of bytes used by the in-memory image per view, or 0 if there is no in-memory image.
Since each view is a stack of z_size pages, this is get_z_size() * get_ram_page_size().
◆ get_render_to_texture
|
inline |
Returns a flag on the texture that indicates whether the texture is intended to be used as a direct-render target, by binding a framebuffer to a texture and rendering directly into the texture.
Normally, a user should not need to set this flag directly; it is set automatically by the low-level display code when a texture is bound to a framebuffer.

Returns the image data associated with the "simple" texture image.
This is provided for some textures as an option to display while the main texture image is being loaded from disk.
Unlike get_ram_image(), this function will always return immediately. Either the simple image is available, or it is not.
The "simple" image is always 4 components, 1 byte each, regardless of the parameters of the full texture. The simple image is only supported for ordinary 2-d textures.

◆ is_cacheable
| bool Texture::is_cacheable |
Returns true if there is enough information in this Texture object to write it to the bam cache successfully, false otherwise.
For most textures, this is the same as has_ram_image().
◆ set_alpha_filename
|
inline |
Sets the name of the file that contains the image's alpha channel contents.
Normally, this is set automatically when the image is loaded, for instance via Texture::read().
The Texture's get_filename() function returns the name of the image file that was loaded into the buffer. In the case where a texture specified two separate files to load, a 1- or 3-channel color image and a 1-channel alpha image, this Filename is update to contain the name of the image file that was loaded into the buffer's alpha channel.
◆ set_alpha_fullpath
|
inline |
Sets the full pathname to the file that contains the image's alpha channel contents, as found along the search path.
Normally, this is set automatically when the image is loaded, for instance via Texture::read().
◆ set_anisotropic_degree
|
inline |
Specifies the level of anisotropic filtering to apply to the texture.
Set this 0 to indicate the default value, which is specified in the texture- anisotropic-degree config variable.
To explicitly disable anisotropic filtering, set this value to 1. To explicitly enable anisotropic filtering, set it to a value higher than 1; larger numbers indicate greater degrees of filtering.
This sets the default sampler state for this texture; it may still be overridden by a sampler state specified at a higher level.

◆ set_aux_data
| void Texture::set_aux_data |
Records an arbitrary object in the Texture, associated with a specified key.
The object may later be retrieved by calling get_aux_data() with the same key.
These data objects are not recorded to a bam or txo file.

◆ set_border_color
|
inline |
Specifies the solid color of the texture's border.
Some OpenGL implementations use a border for tiling textures; in Panda, it is only used for specifying the clamp color.
This sets the default sampler state for this texture; it may still be overridden by a sampler state specified at a higher level.
◆ set_clear_color
|
inline |
Sets the color that will be used to fill the texture image in absence of any image data.
It is used when any of the setup_texture functions or clear_image is called and image data is not provided using read() or modify_ram_image().
This does not affect a texture that has already been cleared; call clear_image to clear it again.
◆ set_component_type
|
inline |
Changes the data value for the texture components.
This implicitly sets component_width as well.
Definition at line 366 of file texture.h.
Referenced by GraphicsOutput::add_render_texture(), and FrameBufferProperties::setup_depth_texture().
◆ set_compression
|
inline |
Requests that this particular Texture be compressed when it is loaded into texture memory.
This refers to the internal compression of the texture image within texture memory; it is not related to jpeg or png compression, which are disk file compression formats. The actual disk file that generated this texture may be stored in a compressed or uncompressed format supported by Panda; it will be decompressed on load, and then recompressed by the graphics API if this parameter is not CM_off.
If the GSG does not support this texture compression mode, the texture will silently be loaded uncompressed.
Definition at line 405 of file texture.h.
Referenced by GraphicsOutput::add_render_texture().
◆ set_default_sampler
|
inline |
This sets the default sampler state for this texture, containing the wrap and filter properties specified on the texture level; it may still be overridden by a sampler state specified at a higher level.
This encompasses the settings for get_wrap_u, get_minfilter, get_anisotropic_degree, etc.
This makes a copy of the SamplerState object, so future modifications of the same SamplerState will have no effect on this texture unless you call set_default_sampler again.
◆ set_filename
|
inline |
Sets the name of the file that contains the image's contents.
Normally, this is set automatically when the image is loaded, for instance via Texture::read().
The Texture's get_name() function used to return the filename, but now returns just the basename (without the extension), which is a more useful name for identifying an image in show code.
◆ set_format
|
inline |
Changes the format value for the texture components.
This implicitly sets num_components as well.
Definition at line 362 of file texture.h.

Sets the full pathname to the file that contains the image's contents, as found along the search path.
Normally, this is set automatically when the image is loaded, for instance via Texture::read().
◆ set_keep_ram_image
|
inline |
Sets the flag that indicates whether this Texture is eligible to have its main RAM copy of the texture memory dumped when the texture is prepared for rendering.
This will be false for most textures, which can reload their images if needed by rereading the input file. However, textures that were generated dynamically and cannot be easily reloaded will want to set this flag to true, so that the texture will always keep its image copy around.
◆ set_loaded_from_image

◆ set_match_framebuffer_format
|
inline |
Sets the special flag that, if true, indicates to the GSG that the Texture's format should be chosen to exactly match the framebuffer's format, presumably because the application intends to copy image data from the framebuffer into the Texture (or vice-versa).
This sets only the graphics card's idea of the texture format; it is not related to the system-memory format.

◆ set_num_views
|
inline |
Sets the number of "views" within a texture.
A view is a completely separate image stored within the Texture object. Most textures have only one view, but a stereo texture, for instance, may have two views, a left and a right image. Other uses for multiple views are not yet defined.
If this value is greater than one, the additional views are accessed as additional pages beyond get_z_size().
This also implicitly unloads the texture if it has already been loaded.

◆ set_post_load_store_cache
|
inline |
Sets the post_load_store_cache flag.
When this is set, the next time the texture is loaded on a GSG, it will automatically extract its RAM image from the GSG and save it to the global BamCache.
This is used to store compressed RAM images in the BamCache. This flag should not be set explicitly; it is set automatically by the TexturePool when model-cache-compressed-textures is set true.
◆ set_quality_level

inline |
◆ set_render_to_texture
|
inline |
Sets a flag on the texture that indicates whether the texture is intended to be used as a direct-render target, by binding a framebuffer to a texture and rendering directly into the texture.
This controls some low-level choices made about the texture object itself. For instance, compressed textures are disallowed when this flag is set true.
Normally, a user should not need to set this flag directly; it is set automatically by the low-level display code when a texture is bound to a framebuffer.
