You can maintain the proportions of the bitmap by enabling the Maintain aspect ratio check box and typing a value in either the Width or Height box.

You can also resample the bitmap as a percentage of its original size by typing values in the % boxes.

Applying special effects to bitmaps

You can apply a wide range of special effects to bitmaps, such as three-dimensional and artistic effects.

Adding plug-in filters to CorelDRAW provides additional features and effects that you can use to edit images. You can add plug-in filters and you can remove them when you no longer need them.
