Academic Courseware: Chapter 6

You can set animation-specific GIF options—Frame Delay, Disposal

Method, and Loop. 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 among computer systems,

so the actual animation display rate may be lower. 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 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.

Create a slide show of your portfolio

1 Scan or use a digital camera to photograph your artwork. Try for a

minimum of 6 to 10 pieces.

2 Copy your work to a new folder called Web Portfolio.

3 Resize the artwork to 72 ppi and no more than 200 x 200 pixels. Save

the resized versions in your new folder so your originals are left intact.

4 Assuming you have 10 pieces of art for your show, open a new frame

stack, 200 x 200 pixels at 72 ppi and 10 frames.

5 Copy your artwork file and paste it into a frame of your movie.

Remember to drop it so it is not accidentally deposited when you

move to the next frame. Repeat until you have a different piece of

your artwork in each frame of your movie.

6 Save the completed frame stack as a GIF. Painter does not open GIF

files as frame stacks so make sure you save your file under a different

name than your frame stack.

7 In the GIF options dialog box, set your color choices. Under the

animation options, set the frame delay to the interval you desire, as

well as the disposal method you would like to use. Decide how often

you would like the slide show to repeat and set that number under

Loop.

8 Open the file in your browser to watch the slide show.
