Detailed Description

This is the set of characteristics of a texture that, if different from another texture, prevent the two textures from sharing a PaletteImage.

It includes properties such as mipmapping, number of channels, etc.

Member Function Documentation

◆ clear_basic()

void TextureProperties::clear_basic ( )

Resets only the properties that might be changed by update_properties() to a neutral state.

Definition at line 93 of file textureProperties.cxx.

Referenced by ImageFile::clear_basic_properties().

◆ complete_pointers()

int TextureProperties::complete_pointers	(	TypedWritable **	p_list,
		BamReader *	manager
	)

virtual

Called after the object is otherwise completely read from a Bam file, this function's job is to store the pointers that were retrieved from the Bam file for each pointer object written.

The return value is the number of pointers processed from the list.

Reimplemented from TypedWritable.

Definition at line 783 of file textureProperties.cxx.

References TypedWritable::complete_pointers().

◆ egg_properties_match()

bool TextureProperties::egg_properties_match ( const TextureProperties & other ) const

Returns true if all of the properties that are reflected directly in an egg file match between this TextureProperties object and the other, or false if any of them differ.

Definition at line 475 of file textureProperties.cxx.

Referenced by TextureReference::is_equivalent().

◆ fillin()

void TextureProperties::fillin	(	DatagramIterator &	scan,
		BamReader *	manager
	)

virtual

Reads the binary data from the given datagram iterator, which was written by a previous call to write_datagram().

Reimplemented from TypedWritable.

◆ force_grayscale()

void TextureProperties::force_grayscale ( )

Sets the actual number of channels to indicate a grayscale image, presumably after discovering that the image contains no colored pixels.

◆ force_nonalpha()

void TextureProperties::force_nonalpha ( )

Sets the actual number of channels to indicate an image with no alpha channel, presumably after discovering that the alpha channel contains no meaningful pixels.
