Graphics have a rectangular frame which allows you to crop them. You can draw any shape with PageStream's drawing tools and use it to mask, or crop, parts of the graphic outside of this irregular frame. PageStream can also generate a mask automatically for certain bitmapped pictures.

Masking
Graphics
To mask a graphic: Draw a shape
or path and put it on
top of the graphic to mask. Select both the graphic and the shape
or path with the Object tool. Choose Mask Graphic from the Mask
submenu in the Object menu. If you wrap
text around the graphic, it will now flow around the mask
rather than the rectangular frame.
To unmask a masked graphic: Select the masked graphic with
the Object tool. Choose Release Mask from the Mask submenu in
the Object menu to separate the masked graphic into its original
graphic and path objects, or choose Clear Mask to delete the mask
path.
Generating
a Mask AutomaticallyIf you want to wrap text around the subject of a bitmapped picture, you can draw a path around the subject and use the path as a mask. PageStream can generate the mask automatically if the subject is on a white background.
To generate a mask: Select a picture with the Object tool.
Choose Generate Mask from the Mask submenu in the Object menu.
Choose Text Wrap from the Object menu to display the Text Wrap
dialog box. Select Shape from the Wrap Around pop-up menu. Enter
horizontal and/or vertical text offset values, and select a text
wrap method by clicking on an icon. Click OK.
 Masks generated
automatically are not pixel-accurate so they should not be used
to clip pictures overlaid on other pictures. To overlay pictures
with white backgrounds, merge the pictures with an image processor
before importing into PageStream. |
