Enumeration Type Documentation

FLI_CHUNK_TYPE

enum FLI_CHUNK_TYPE

[AI] Enumerates the chunk types used in the FLIC animation file format.

These chunk types define the encoding, compression, and image/palette data present in a FLIC stream, as per the Autodesk FLIC file specification.

[AI] FLIC animation files (FLC/FLI) use different chunk types to store animation frames, palette data, and compress pixel data. Each chunk specifies how its contained data should be interpreted to reconstruct or update an animation frame.

Enumerator
FLI_CHUNK_COLOR256	256-level color palette info. Updates the color lookup table with 256 entries. [AI]
FLI_CHUNK_SS2	Word-oriented delta compression. Efficient for lines with word-aligned runs or minimal pixel changes. [AI].
FLI_CHUNK_COLOR64	64-level color palette info. Updates only 64 palette entries. [AI]
FLI_CHUNK_LC	Byte-oriented delta compression. Encodes lines with byte-level difference encoding. [AI].
FLI_CHUNK_BLACK	Entire frame is filled with color index 0 (black). [AI].
FLI_CHUNK_BRUN	Byte run-length compression. Lossless RLE for frame data. [AI].
FLI_CHUNK_COPY	No compression; raw pixel data for the frame. [AI].
FLI_CHUNK_PSTAMP	Postage stamp sized image for previews/thumbnails. [AI].
FLI_CHUNK_FRAME	Marks the start of a FLIC animation frame. [AI].

Function Documentation

DecodeFLCFrame()

void DecodeFLCFrame	(	LPBITMAPINFOHEADER	p_bitmapHeader,
		BYTE *	p_pixelData,
		FLIC_HEADER *	p_flcHeader,
		FLIC_FRAME *	p_flcFrame,
		BYTE *	p_decodedColorMap
	)

[AI] Decodes a single FLIC (FLI/FLC) animation frame and updates the pixel data and palette.

[AI] Reads the frame, applies decompression and color/palette updates, and writes the updated result into the destination bitmap.

Parameters

p_bitmapHeader	[AI] Pointer to the Windows DIB BITMAPINFOHEADER structure describing the destination bitmap. Must match the dimensions of the FLIC data.
p_pixelData	[AI] Pointer to the raw pixel data buffer where decoded image output will be written.
p_flcHeader	[AI] Pointer to the global FLIC_HEADER for this animation.
p_flcFrame	[AI] Pointer to the frame header (FLIC_FRAME) describing this animation frame.
p_decodedColorMap	[AI] Output flag, set to TRUE if this frame updates the color palette, FALSE otherwise. Used to signal palette changes.
