In bitmap editing, noise is defined as the random pixels that display across an image, which resemble static on television screens. The noise special effects let you create, control, or eliminate noise.

To apply the effects that are labeled with ‘Corel PHOTO-PAINT’, you need to edit the bitmap in Corel PHOTO-PAINT. To send a bitmap to Corel PHOTO-PAINT, you can click the Edit bitmap button on the property bar, or you can use the Edit bitmap command from the Bitmaps menu. You can also enable an option that lets you access Corel PHOTO-PAINT by double-clicking a bitmap. For more information, see Edit bitmaps with Corel PHOTO-PAINT.
