Functions

apply_pstamp_xlat256	Apply the translation table to the pixels in the raster, mapping the pixels to the postage stamp's six-cube palette.
can_encode_fli_black	True if the frame can be encoded by FLI_BLACK.
chunk_modifies_palette	Returns true if the chunk type modifies the palette.
decode_chunk	Decode a chunk, based on the chunk type.
decode_fli_black	Decode a FLI_BLACK chunk.
decode_fli_brun	Decode a FLI_BRUN chunk.
decode_fli_color64	Decode a FLI_COLOR64 chunk.
decode_fli_color256	Decode a FLI_COLOR256 chunk.
decode_fli_copy	Decode a FLI_COPY chunk.
decode_fli_icolors	Decode a FLI_ICOLORS chunk.
decode_fli_lc	Decode a FLI_LC chunk.
decode_fli_sbsrsc	Decode a FLI_SBSRSC chunk.
decode_fli_ss2	Decode a FLI_SS2 chunk.
decode_fli_wrun	Decode a FLI_WRUN chunk.
decode_fps_brun	Decode a FPS_BRUN chunk.
decode_fps_copy	Decode a FPS_COPY chunk.
encode_fli_brun	Encode a FLI_BRUN chunk.
encode_fli_color64	Encode a FLI_COLOR64 chunk.
encode_fli_color256	Encode a FLI_COLOR256 chunk.
encode_fli_copy	Encode a FLI_COPY chunk.
encode_fli_lc	Encode a FLI_LC chunk.
encode_fli_ss2	Encode a FLI_SS2 chunk.
make_pstamp_pal	Create the postage stamp's six-cube palette.
make_pstamp_xlat256	Create a translation table to map the palette into the postage stamp's six-cube palette.
prepare_pstamp	Create a new scaled down image, remapped into the six-color palette. The image may be encoded as part of a postage stamp chunk using the FLI_BRUN and FLI_COPY encoders.
