Lenses let you view adjustments and special effects that you want to apply to an image. When you create a lens, the changes you make are not applied to the image pixels; instead, they are displayed on the screen through the lens. The lens is created as a separate object on a layer above the image background so you can edit the lens and the background image separately. When you achieve the results you want, you can combine the lens with the image background. When you export or print an image, the effects of the lens are applied to the exported or printed image.
The features documented in the Help are available in the full version of CorelDRAW Graphics Suite 2020. Some features may not be available in this version of the product.
