Corel Painter 443
If you want to gradually display
images in the Web browser as they
load, you can enable the Interlaced
option.
If you have created selections in each
frame, you can make your image
transparent and choose your
background option. You might need to
adjust the Threshold slider to
determine at what selection mask
value the image becomes transparent.
For more information on these GIF
options, refer to “Saving GIF Files” on
page 48.
You can also set animation-specific
GIF options—Frame Delay, Disposal
Method, and Looping.
The Frame Delay allows you to
specify a pause (in 100ths of a second)
between each frame. Without a delay,
the frames appear as quickly as the
system can load and display them.
The display of each image (especially
with larger frames) will vary between
computer systems, so the actual
animation display rate may be lower.
You can use the Frame Delay to
approximate a particular frame rate.
For example, you capture some one-
quarter size video at 8 frames per
second (fps). You want 8 frames to
appear in one second, so divide one
second (100 hundredths of a second)
by 8. The result is 8/100=12.5.
Discard the decimal portion and enter
12 as the frame delay. Discarding the
decimal is the only allowance for the
time required to display each image.
For a large frame size, you might want
to allow more time for display.
The Disposal Method lets you specify
what happens to an image after it has
been displayed (and its frame delay
has passed), and before the next image
is displayed. The disposal method is
significant only when using
transparency that differs between
frames.
• With Default, the client browser’s
default disposal method is used.
• With None, the image is left on-
screen and the next frame is
rendered over it.
• With Background, the region
covered by the image is restored to
the background color.
• With Previous, the region covered
by the graphic is returned to the
imagery of the previous frame.
If you want the animation to repeat,
enable the Loop option. Enter the
number of times the animation should
repeat. If you want it to repeat
indefinitely, enter 0 (zero).
To export a frame stack as an
animated GIF:
1 With the frame stack open, choose
File menu > Save As.
2 In the Save Movie dialog box,
choose Save Movie as GIF
Animation.
3 In the Enter Movie Name dialog
box, choose a location, enter a
filename, and click Save.
4 In the Save as GIF Options dialog
box, specify the options you want.
You can now use your browser to open
the file and view the animation. You
can place the animation on a Web
page with the same HTML image tag
you’d use for a simple GIF file.
