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, to the original. However, because the JPEG algorithm takes into account the

sensitivity of the eye to different colors, the higher-quality settings should achieve visually satisfying results.

You can assign a URL to layers and placed images and then save the file in GIF or JPEG format to produce

an image map. For more information, see “Creating image maps” on page 883.

When you save a file in JPEG format, Corel Painter displays the JPEG Encoding Quality dialog box, with the

following options:

• The Quality options — Excellent, High, Good, and Fair — let you set the degree of file compression.

The Excellent option compresses the least, but retains the most data. Fair compresses the most, but

loses the most data.

You can also use the Quality slider to adjust file compression.

• The Smoothness slider applies smoothing to the entire image. This is useful when using the Fair option

to blur the edges of JPEG artifacts. The default is 0. Keep in mind that using a high smoothness setting

can cause blurring.
