3 In the Save Image As dialog box, choose a location and file format,
enter a name for the first file. You must begin or end the filename
with a number—for example, “01Movie” or “Animation14.”

1 Choose File > Open.
2 In the Select Image dialog box, enable the Open Numbered Files
check box. Double-click the last numbered file. (You can also select
the file and click Open).

new frame stack.
Exporting movies for the Web
Corel Painter allows exporting a frame stack as an animated GIF file
which can be displayed on a Web page. Animated GIFs can be used to
animate Web banners, greeting cards and short films for the Web.
The primary concern in designing animation for the Web is file size. The
larger the file, the longer it will take to load. Most Web visitors will not
want to wait very long for an animation to load, especially if the
animation is not very informative or is strictly decorative. With that
said, all the animation techniques you have learned so far, with a little
planning for file economy, can be used to create animation for the Web.
Understanding GIF options
“GIF” stands for Graphics Interchange Format, a file format using 8 or
fewer bits. That means that when you save a GIF file, you can choose
settings from 4 colors to no more than 256 colors. However, you can
choose how your colors will be displayed and even choose to make a part
of your image transparent.
When saving a GIF, you can enable the Color Set option to force all
colors in the GIF file to match the colors in the current color set. This
option is especially useful if you want to constrain colors to a specific
color set or control the number of colors in a Web page, thus controlling
the image file size. Corel Painter has a “Web-safe” color set, mapping to
the default Netscape Navigator® color set.
Most Web visitors will not
wait a long time for pages to load. Not
everyone has high-speed Web access.
Try to design for a typical modem speed
of 56,600 bps. Test your pages on
different platforms to see how they hold
up. Macintosh computers typically use
a brighter gamma setting than the PC.
You want your work to look good
under a variety of circumstances.
To make your animation files
smaller, you can reduce the frame size.
Limiting the number of frames is
another way to shrink file size.
