CPT to SGI Conversion: FAQ

What are CPT files?

The CPT file extension is associated with Corel PHOTO-PAINT, a raster graphics editor developed by Corel. CPT files use Corel PHOTO-PAINT's own bitmap format to store edited digital photos. In other words, they are graphic files with distinct layers, alpha channels and transparency, all of which allow for future image editing. CPT is very similar to the TIFF format in terms of image quality and size, but the latter tends to be more popular and easier to handle using regular image viewers.

What are SGI files?

SGI (Silicon Graphics Image) is a raster image format associated with Silicon Graphics workstations. It is a bitmap file that can store black-and-white, gray-scale and color images, and may also contain color maps and alpha channels. SGI files are sometimes referred to as RGBs and can either use no image compression or RLE compression. Alternative extensions for the SGI format are BW, RGB and RGBA.
