CImage

What is a CImage?

CImage is a format used to store information and data for an image.

Size	Type	Name	Description
4	UInt32	Handle	The handle of the image, used to reference the image by other structures
4	UInt32	Unknown	Allegedly a checksum of the data after Data Size, unsure if accurate or the usage
4	UInt32	References	The number of references made to this image in the project, used to determine if the image should be removed from the project
4	UInt32	Data Size	The size of the Image Data
2	Int16	Width	The width of the image
2	Int16	Height	The height of the image
1	EImageFormat	Image Format	The format of the image
1	UInt8	Flags	Definitions
2		Unknown	Presumably padding
2	Int16	Hotspot X	The X coordinate of the Hotspot
2	Int16	Hotspot Y	The Y coordinate of the Hotspot
2	Int16	Action Point X	The X coordinate of the Action Point
2	Int16	Action Point Y	The Y coordinate of the Action Point
4	RGBA	Transparent Color	The color used for transparency if the Alpha and RGBA flags are both disabled
Data Size	UInt8[]	Image Data	The raw data of the image file, if the LZX flag is enabled, the first 4 bytes are the decompressed size, then the rest is compressed using LZX

Value	Name	Description
0x01	RLE	Image pixel data is RLE compressed, with command bytes controlling run length and repeat behavior
0x02	RLEW	Unknown, observed behaviour is similar to RLE
0x04	RLET	Unknown, observed behaviour is similar to RLE but differs with padding
0x08	LZX	Image pixel data is LZX compressed
0x10	Alpha	Image contains a separate alpha channel appended after the pixel data
0x20	ACE	Unknown
0x40	Mac	Unknown, presumably set for the Mac runtime when compiled
0x80	RGBA	Image pixel data already contains an interleaved alpha channel rather than a separate one
