Member Function Documentation

void TextureMemoryCounter::add_palette (  PaletteImage *  image  )  [private]

Adds the indicated PaletteImage to the count. If this is called twice for a given PaletteImage it does nothing. Definition at line 178 of file textureMemoryCounter.cxx. References _duplicate_bytes, _num_textures, and _textures.

void TextureMemoryCounter::add_placement (  TexturePlacement *  placement  )

Adds the indicated TexturePlacement to the counter. Definition at line 76 of file textureMemoryCounter.cxx. References _num_placed. Referenced by Palettizer::test_palette_group().

void TextureMemoryCounter::add_texture (  TextureImage *  texture, int  bytes )  [private]

Adds the given TextureImage to the counter. If the texture image has already been added, this counts the smaller of the two as duplicate bytes. Definition at line 209 of file textureMemoryCounter.cxx. References TextureProperties::_format, EggTexture::F_rgb, EggTexture::F_rgb12, EggTexture::F_rgba, EggTexture::F_rgba12, EggTexture::F_rgba8, EggTexture::F_rgbm, and ImageFile::get_properties().

int TextureMemoryCounter::count_bytes (  ImageFile *  image, int  x_size, int  y_size )  [private]

Attempts to estimate the number of bytes the given image file will use in texture memory. Definition at line 251 of file textureMemoryCounter.cxx. References EggTexture::F_alpha, and EggTexture::F_luminance.

int TextureMemoryCounter::count_bytes (  ImageFile *  image  )  [private]

Attempts to estimate the number of bytes the given image file will use in texture memory. Definition at line 236 of file textureMemoryCounter.cxx. References EggTexture::F_blue, EggTexture::F_green, EggTexture::F_luminance_alpha, EggTexture::F_luminance_alphamask, EggTexture::F_red, EggTexture::F_rgb332, EggTexture::F_rgb5, EggTexture::F_rgb8, EggTexture::F_rgba4, and EggTexture::F_rgba5.

ostream & TextureMemoryCounter::format_memory_fraction (  ostream &  out, int  fraction_bytes, int  palette_bytes )  [static, private]

Writes to the indicated ostream an indication of the fraction of the total memory usage that is represented by fraction_bytes. Definition at line 159 of file textureMemoryCounter.cxx.

void TextureMemoryCounter::report (  ostream &  out, int  indent_level )

Reports the measured texture memory usage. Definition at line 111 of file textureMemoryCounter.cxx. Referenced by Palettizer::test_palette_group().

void TextureMemoryCounter::reset (   )

Resets the count to zero. Definition at line 53 of file textureMemoryCounter.cxx. References _coverage_bytes, _duplicate_bytes, _palettes, and _textures.
