In CorelDRAW software, different filters can produce different effects. Proper use of these filters can enrich the image and create unexpected effects.

Add filter effects

The method of adding filter effects is relatively simple. Simply select the image, click on the bitmap tab, choose the desired filter group from its drop-down menu, expand the filter group menu, and click on a filter effect to add.

The filter effects in CorelDRAW generally have parameters. After selecting the desired filter effect, a corresponding parameter setting dialog box will pop up. After setting the parameters, you can view the filter effect through the preview window. Click the "OK" button to apply the effect to the selected graphic.

Remove filter effect

If you are not satisfied with the added filter effect, you can restore the graphic to its original state before applying the filter effect through the restore operation in CorelDRAW. After restoration, if the filter effect still needs to be applied, it can be restored through the redo function.

To undo the applied filter effect: click Edit → undo, or use the shortcut Ctrl+Z key combination.

If no other editing or modifications have been made to the image, you can click Edit → Redo, or use the shortcut key combination Shift+Ctrl+Z.
