CCX (Corel)

Corel CCX is a vector graphics file format, used for example in the Corel Gallery 1 Million clip art collection. It is a compressed form of CMX (Corel Presentation Exchange).

See also Corel Gallery.

Disambiguation
Some format lists say there is a CPX/.cpx format, described as "CMX compressed", but evidence is lacking.

Corel says that the Corel ArtShow 5 book+CD product used a CPX format. More research may be needed here.

Format details
CCX is based on RIFF, with some of the RIFF structure compressed inside a special " " chunk. It (usually?) uses zlib compression.

Identification
CMX files start with "", and have "" at offset 8.
