CPT (file format)
|Type of format||proprietary raster image format|
The CPT file format is a graphics file format used by some versions of Corel Photo Paint. It is also possible to open CPT version 6 files with IrfanView, but not with Paint Shop Pro (although it is from Corel). CPT version 6 is an almost identical copy of the TIFF format, whereas since Corel Photo-Paint 7.0 (released in 1997), this was deprecated for a new proprietary format (known as CPT7), however the user can still export the older TIFF-based CPT6 files.
Corel Photo Paint is not released as a standalone program. It is part of the Corel Draw Graphics Suite, available only for Windows.
