Exporting objects with transparent colors and backgrounds
Corel DESIGNER lets you export palette-based bitmaps, such as paletted GIF or 8-bit PNG, with transparent colors and backgrounds. These
bitmaps can contain objects, such as buttons and logos, which are commonly used on webpages with colored or patterned backgrounds.
If you place an object with an opaque background onto a webpage, the object background color appears as a rectangle on the page. By
making an object background transparent, the object background blends in with the page. Transparent object backgrounds also let you
change the color or pattern of a webpage background without having to change the backgrounds of the objects to match.
You can create a GIF with a transparent background to use on a webpage.
To save a bitmap with a transparent background
1 In the Export for web dialog box, choose a paletted file format, such as GIF or 8-bit PNG, from the Format list box.

Creating rollovers
Rollovers are interactive objects that change in appearance when you click or point to them. You can create rollovers using objects.
To create a rollover, you add the following rollover states:
• Normal — the default state of a button when no mouse activity is associated with the button
• Over — the state of a button when the pointer passes over it
• Down — the state of a clicked button
You can apply different object properties to each of the rollover states. You can also preview the rollover states.
