Choosing a file format
When you save a file, you must choose a file format. The following section contains
information about some of the supported file formats.
Saving RIFF files
RIFF is the Corel Painter file format, which retains special information about your
document. For example, a RIFF file maintains all layers.
RIFF files are best used as “work-in-progress” files. It is recommended that you always
save files in RIFF format, and then save to GIF, JPEG, TIF, or another file format when
a file is ready for production.
Corel Painter lets you compress files and save disk space with a lossless compression
method. When saving in RIFF format, you can minimize the file size on your hard disk
by ensuring that the Uncompressed option is disabled by default.
Saving JPEG files
Corel Painter supports the JPEG file format. Unlike GIF, the JPEG file format displays
a full range of colors.
The JPEG file format lets you compress your file on a scale of Fair to Excellent, where
quality is directly proportional to file size. These quality settings will let you achieve
compression ratios ranging from less than 10:1 to greater than 100:1. JPEG is a “lossy”
file format, meaning that a compressed JPEG file will not be identical, pixel-for-pixel,
