Setting bitmap properties

You can apply anti-aliasing to an imported bitmap to smooth the edges in the image. You can also select a compression option to reduce the bitmap file size and format the file for display on the Web.

To select bitmap properties, you use the Bitmap Properties dialog box.

To set bitmap properties:

1 | Select a bitmap in the Library panel.
2 | Do one of the following:
| Click the properties icon at the bottom of the Library panel.
| Right-click (Windows) or Control-click (Macintosh) the bitmap's icon and choose Properties from the context menu.
| Choose Properties from the options menu in the upper right corner of the Library panel.
3 | In the Bitmap Properties dialog box, select Allow Smoothing to smooth the edges of the bitmap with anti-aliasing.
4 | For Compression, choose one of the following options:
| Choose Photo (JPEG) to compress the image in JPEG format. To use the default compression quality specified for the imported image, select Use Document Default Quality. To specify a new quality compression setting, deselect Use Document Default Quality and enter a value between 1 and 100 in the Quality text box. (A higher setting preserves greater image integrity but yields a larger file size.)
| Choose Lossless (PNG/GIF) to compress the image with lossless compression, in which no data is discarded from the image.
| Note: Use Photo compression for images with complex color or tonal variations, such as photographs or images with gradient fills. Use Lossless compression for images with simple shapes and relatively few colors.
5 | Click Test to determine the results of the file compression. Compare the original file size to the compressed file size to determine if the selected compression setting is acceptable.
6 | Click OK.
| Note: JPEG Quality settings that you select in the Publish Settings dialog box do not specify a quality setting for imported JPEG files. You must specify a quality setting for imported JPEG files in the Bitmap Properties dialog box.
