CPT (file 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.

The .cpt extension is also used for files encrypted using ccrypt, and also for screen captures in the video game Tekken Tag Tournament (PlayStation 2), which are saved to the Memory Card.

Corel Photo-Paint

Corel Photo-Paint is a raster graphics editor developed and marketed by Corel since 1992. Corel currently markets the software for Windows operating systems, previously having marketed versions for Linux (Version 9, requiring Wine) and Mac OS (through version 11). Its primary market competitor is Adobe Photoshop.

In 2006, Corel released version 13 as Photo-Paint X3, employing this naming convention for subsequent releases as well as for CorelDraw, included with Photo-Paint in CorelDraw Graphics Suite. The current version is Photo-Paint X7. Corel has marketed a limited edition of Photo-Paint called Corel Photo-Paint SELECT with HP scanning hardware, e.g., the HP ScanJet 5p scanners.

Features

Photo-Paint's native format is .CPT (Corel Photo-Paint Image), which stores image data as well as information within an image, including objects (layers in some raster editors), colour profiles, text, transparency, effect filters.

The program can open and convert vector formats from CorelDraw and Adobe Illustrator and can open other formats, including PNG, JPG and GIF files — as well as competing photo editor formats from Photoshop, GIMP and Paint Shop Pro (the latter also a Corel product). The program also supports plug-in functionality including those developed for Adobe Photoshop and Paint Shop Pro. Other extensions such as brushes are also compatible with Photo-Paint.
