Creating an interlaced image

When a Web browser downloads a normal GIF image, the image gradually appears, line by line, from top to bottom on the screen. If an image is large and takes a long time to download, this can be frustrating for someone viewing it. Your audience might have to wait for almost the entire image to download before they really know what the image is.

To avoid this problem, you can change an image so that it is interlaced. When a browser downloads an interlaced GIF image, a rough outline of the entire image is displayed first and then detail is gradually added.

Note When Claris Home Page converts image files to GIF format, the images are automatically set to be interlaced. For more information on image conversion, see Converting image files to GIF format.

To make an image interlaced:

1. Double-click the image to open the Image Object Editor.
   
2. Click the Appearance tab, if necessary, to display a new set of options.
   
3. Click Set to open the image file in the Transparency and Interlacing Image Editor.
   
4. Click the Interlace button on the toolbar.
   
   To change the image back into a non-interlaced image, click the Don't Interlace button .
   
5. Close the Transparency and Interlacing Image Editor and save the changes to the image file when Claris Home Page prompts you to.
   
   The image file is stored and displayed as an interlaced image.

Tip To open the image in the Transparency and Interlacing Image Editor using the mouse, right-click (Windows) or Control-click (Macintosh) the image and choose Transparency and Interlacing from the pop-up menu.
