name, location, and format.
Saving RIF Files
RIF is the Corel Painter native format,
which retains special information
about your document. For example, a
RIF file maintains layers so you can
return to the file to re-access them.
It’s a good idea to always save files in
RIF format first. Think of RIF files as
“work in progress” files. When a file is
ready for production, then save it to
GIF, JPEG, CMYK, TIF, or another
file format.
Corel Painter lets you compress files
and save disk space with a lossless
compression method.
When saving in RIF format, leave the
Uncompressed option disabled to
minimize file size on your hard disk.
Saving JPEG Files
Corel Painter supports the JPEG file
format. Because of its small file size
and high quality, JPEG is commonly
used to transmit files through a
modem. Unlike GIF, JPEG displays a
full range of colors.
JPEG allows you to 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 of less than
10:1 to greater than 100:1. JPEG is a
“lossy” file format, meaning that a
decompressed 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,
refer to “Client-Side Image Mapping”
on page 406.
When you save a file in JPEG format,
Corel Painter displays the JPEG
dialog box, with the following options:
• The JPEG Encoding Quality
options—Excellent, High, Good,
and Fair—let you set file
compression on a scale of
Excellent to Fair.
The Excellent option compresses
the least, but retains the most data.
Fair compresses the most, but loses
the most data.
• The Quality slider adjusts the
quality.
• 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.
• The JPEG preview window
displays any changes you make to
the image as you work.
• The Progressive JPEG option
creates a progressive JPEG file.
Progressive format is useful when
using a file on the Web. As the
