Detailed Description

This represents a single egg file known to the palettizer.

It may reference a number of textures, and may also be assigned to a number of groups. All of its textures will try to assign themselves to one of its groups.

Definition at line 36 of file eggFile.h.

Member Function Documentation

◆ apply_properties_to_source()

void EggFile::apply_properties_to_source ( )

Calls apply_properties_to_source() for each texture reference, updating all the referenced source textures with the complete set of property information from this egg file.

Definition at line 364 of file eggFile.cxx.

References TextureReference::apply_properties_to_source().

◆ build_cross_links()

void EggFile::build_cross_links ( )

Calls TextureImage::note_egg_file() and SourceTextureImage::increment_egg_count() for each texture the egg file references, and PaletteGroup::increment_egg_count() for each palette group it wants.

This sets up some of the back references to support determining an ideal texture assignment.

Definition at line 325 of file eggFile.cxx.

References PaletteGroups::clear(), PaletteGroups::empty(), TextureReference::get_texture(), PaletteGroups::insert(), and PaletteGroups::make_complete().

◆ choose_placements()

void EggFile::choose_placements ( )

Once all the textures have been assigned to groups (but before they may actually be placed), chooses a suitable TexturePlacement for each texture that appears in the egg file.

This will be necessary to do at some point before writing out the egg file anyway, and doing it before the textures are placed allows us to decide what the necessary UV range is for each to- be-placed texture.

Definition at line 381 of file eggFile.cxx.

References PaletteGroups::begin(), PaletteGroups::count(), PaletteGroups::empty(), get_complete_groups(), TexturePlacement::get_group(), TextureImage::get_groups(), TextureImage::get_placement(), TextureReference::get_placement(), TextureReference::get_texture(), and PaletteGroups::make_intersection().

◆ clear_surprise()

void EggFile::clear_surprise ( )

Removes the 'surprise' flag; this file has been successfully matched against a line in the .txa file.

Definition at line 285 of file eggFile.cxx.

◆ complete_pointers()

int EggFile::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 740 of file eggFile.cxx.

◆ from_command_line()

bool EggFile::from_command_line ( EggData data,
const Filename source_filename,

Accepts the information about the egg file as supplied from the command line.

Returns true if the egg file is valid, false otherwise.

Definition at line 57 of file eggFile.cxx.

◆ get_complete_groups()

const PaletteGroups & EggFile::get_complete_groups ( ) const

Referenced by choose_placements().

◆ get_default_group()

PaletteGroup * EggFile::get_default_group ( ) const

Returns the PaletteGroup that was specified as the default group on the command line at the time the egg file last appeared on the command line.

Definition at line 91 of file eggFile.cxx.

◆ get_textures()

void EggFile::get_textures ( pset< TextureImage * > &  result) const

Fills up the indicated set with the set of textures referenced by this egg file.

It is the user's responsibility to ensure the set is empty before making this call; otherwise, the new textures will be appended to the existing set.

Definition at line 438 of file eggFile.cxx.

◆ has_data()

bool EggFile::has_data ( ) const

Returns true if the EggData for this EggFile has been loaded, and not yet released.

Definition at line 429 of file eggFile.cxx.

◆ is_stale()

bool EggFile::is_stale ( ) const

Returns true if the egg file needs to be updated, i.e.

some palettizations have changed affecting it, or false otherwise.

Referenced by write_description().

◆ is_surprise()

bool EggFile::is_surprise ( ) const

Definition at line 294 of file eggFile.cxx.

Referenced by Palettizer::report_pi().

◆ mark_stale()

void EggFile::mark_stale ( )

Marks this particular egg file as stale, meaning that something has changed, such as the location of a texture within its palette, which causes the egg file to need to be regenerated.

Referenced by TextureReference::mark_egg_stale().

◆ match_txa_groups()

void EggFile::match_txa_groups ( const PaletteGroups groups)
