Resolution Enter the resolution in pixels per inch for rendering SpriteEffects. The higher the resolution, the smoother effects will appear. However, higher resolution requires more memory and slows down printing. For web graphics and screen display, 72 ppi is the recommended res- olution. For office printing, 100 to 200 ppi is usually sufficient. For commercial printing, a range of 150 to 300 ppi is recommended for halftone images, depending on the paper and press requirements. Anti-Alias Select this option if you want to smooth the edges of objects in the rendering of SpriteEffects. Sizing the effects area When you apply effects to an object, Canvas defines a rectangular effects area. Usually, the effects area is slightly larger than the bounding box of the object the effects are applied to. There is one effects area for all effects applied to an object. Canvas tries to keep the effects area as small as possible, without cropping out any visible objects. You can adjust the effects area using the SpriteEffects palette. The palette lets you set the effects area manually or automatically. You might need to enlarge the effects area to see effects that extend beyond an object’s edge. For example, Motion Blur and plug-in effects like bevel, glow, and fire usually need to extend beyond an object’s outline. Also, if text characters extend outside the text object border, an effect applied to the text could be cut off. If you make the effects area smaller than an object’s bounding box, the object and the effects will be cropped by the effects area border. Sizing the effects area automatically 1 Select the object whose effects area you want to adjust. 2 In the SpriteEffects palette, click the smart-crop icon ( ). 3 A message asks you to confirm that you want to proceed. Click OK. 4 Canvas estimates the correct size of the effects area and makes it as small as possible.
