[Editor's note: This week we have our third tutorial from the good folks at A Lowly Apprentice Productions (ALAP). ALAP is a software developer that makes plugins for both QuarkXPress and Adobe InDesign. —Dave]

This demonstrates a feature of ShadowCaster that enables you to screen back a portion of an image within QuarkXPress.

The result of these steps will produce the following image.

Making a simple mask

The first step to screening back an area of an image, is to create a mask of the area we wish to screen back. In this example, we will draw a simple rectangular text box around our text as illustrated.

In this example, the background color of the text box was set to white so that we can accurately draw our mask.

Fill mask item with a color

In order to create a shadow of this item, we need to fill the background of the text box with a color. Any color can be used except White.

Create a mask shadow

Select the mask item created in Step #2 if not already selected. In the Create Tab, enter these attributes and click Create.

Resolution should be set to the resolution of the background image. Blur Radius can be increased or decreased depending on the amount of feathering into the background you desire. Offset should be set to Zero, since we created the mask item exactly where the image is to be screened. Shading specifies the percentage to shade the background image by.
