Detailed Description

This is the main engine behind egg-palettize.

It contains all of the program parameters, from the command line or saved from a previous session, and serves as the driving force in the actual palettizing process.

Member Function Documentation

◆ add_command_line_egg()

void Palettizer::add_command_line_egg ( EggFile egg_file)

Adds the indicated EggFile to the list of eggs that are considered to have been read on the command line.

These will be processed by process_command_line_eggs().

Definition at line 784 of file palettizer.cxx.

◆ all_params_set()

void Palettizer::all_params_set ( )

Called after all command line parameters have been set up, this is a hook to do whatever initialization is necessary.

Definition at line 406 of file palettizer.cxx.

References PaletteGroup::setup_shadow_images().

◆ complete_pointers()

int Palettizer::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 984 of file palettizer.cxx.

References TypedWritable::complete_pointers().

◆ finalize()

void Palettizer::finalize ( BamReader manager)
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 1045 of file palettizer.cxx.

References downcase().

◆ generate_images()

void Palettizer::generate_images ( bool  redo_all)

Actually generates the appropriate palette and unplaced texture images into the map directories.

If redo_all is true, this forces a regeneration of each image file.

Definition at line 633 of file palettizer.cxx.

References TextureImage::copy_unplaced(), and PaletteGroup::update_images().

◆ get_default_group()

PaletteGroup * Palettizer::get_default_group ( )

Returns the default group to which an egg file should be assigned if it is not mentioned in the .txa file.

Definition at line 824 of file palettizer.cxx.

References get_palette_group(), PaletteGroup::has_dirname(), and PaletteGroup::set_dirname().

◆ get_egg_file()

EggFile * Palettizer::get_egg_file ( const std::string &  name)

Returns the EggFile with the given name.

If there is no EggFile with the indicated name, creates one. This is the key name used to sort the egg files, which is typically the basename of the filename.

Definition at line 749 of file palettizer.cxx.

◆ get_noabs()

bool Palettizer::get_noabs ( ) const

Returns the current setting of the noabs flag.

See set_noabs().

Definition at line 143 of file palettizer.cxx.

◆ get_palette_group()

PaletteGroup * Palettizer::get_palette_group ( const std::string &  name)

Returns the PaletteGroup with the given name.

If there is no PaletteGroup with the indicated name, creates one.

Definition at line 793 of file palettizer.cxx.

Referenced by get_default_group().

◆ get_texture()

TextureImage * Palettizer::get_texture ( const std::string &  name)

Returns the TextureImage with the given name.

If there is no TextureImage with the indicated name, creates one. This is the key name used to sort the textures, which is typically the basename of the primary filename.

Definition at line 838 of file palettizer.cxx.

References downcase().

◆ is_valid()

bool Palettizer::is_valid ( ) const

Returns true if the palette information file was read correctly, or false if there was some error and the palettization can't continue.

Definition at line 167 of file palettizer.cxx.

◆ optimal_resize()

void Palettizer::optimal_resize ( )

Attempts to resize each PalettteImage down to its smallest possible size.

Definition at line 606 of file palettizer.cxx.

References PaletteGroup::optimal_resize().

◆ process_all()

void Palettizer::process_all ( bool  force_texture_read,
const Filename state_filename 
)

◆ process_command_line_eggs()

void Palettizer::process_command_line_eggs ( bool  force_texture_read,
const Filename state_filename 
)

Processes all the textures named in the _command_line_eggs, placing them on the appropriate palettes or whatever needs to be done with them.

If force_texture_read is true, it forces each texture image file to be read (and thus legitimately checked for grayscaleness etc.) before placing.

◆ read_stale_eggs()

bool Palettizer::read_stale_eggs ( bool  redo_all)

Reads in any egg file that is known to be stale, even if it was not listed on the command line, so that it may be updated and written out when write_eggs() is called.

If redo_all is true, this even reads egg files that were not flagged as stale.

Returns true if successful, or false if there was some error.

Definition at line 656 of file palettizer.cxx.

◆ read_txa_file()

void Palettizer::read_txa_file ( std::istream &  txa_file,
const std::string &  txa_filename 
)

Definition at line 619 of file palettizer.cxx.

References PaletteGroup::reset_images().

◆ set_noabs()

void Palettizer::set_noabs ( bool  noabs)

Changes the current setting of the noabs flag.

If this flag is true, then it is an error to process an egg file that contains absolute pathname references. This flag is intended to help detect egg files that are incorrectly built within a model tree (which should use entirely relative pathnames).

This flag must be set before any egg files are processed.

Definition at line 158 of file palettizer.cxx.

◆ string_remap()

Palettizer::RemapUV Palettizer::string_remap ( const std::string &  str)
static

Returns the RemapUV code corresponding to the indicated string, or RU_invalid if the string is invalid.

PaletteGroup * Palettizer::test_palette_group ( const std::string &  name) const

Returns the PaletteGroup with the given name.

bool Palettizer::write_eggs ( )

Adjusts the egg files to reference the newly generated textures, and writes them out.

Returns true if successful, or false if there was some error.
