Compressing bitmaps

If you plan to distribute your movie over the Internet, you can compress your bitmap images to
ensure faster downloading. Director lets you compress images at the movie level and for
individual cast members. Bitmap compression set at the cast member level overrides compression
settings at the movie level.
In addition to Director standard compression, you can use JPEG compression and specify a range
of image quality. If you have Fireworks installed, you can use the Optimize in Fireworks button to
launch Fireworks and then dynamically apply compression settings while viewing how your image
looks at those settings. When you determine the most suitable compression level, Director
remembers the settings you established in Fireworks. For more information, see "Optimizing
Bitmaps in Fireworks" in the Director Support Center website at www.macromedia.com/support/
director/vector/d8/fw_bitmaps.html.
To compress a bitmap at the cast member level:
Select bitmap cast members or sprites, and click the Bitmap tab in the Property inspector.

If you selected multiple cast members or sprites, the Property inspector displays the
compression setting if it is the same for each selected object. If the compression settings are not
the same, the Compression pop-up menu is blank.
Click the Compression pop-up menu, and do one of the following:

To compress selected bitmaps using the same settings as those established for movie-level
compression, select Movie Setting. For more information on setting bitmaps at the movie level,
see the information on the Compression tab under "Changing Publish settings" on page 577.
•
To use the standard Director compression, select Standard.
•
To use JPEG compression, select JPEG, and move the slider bar to the desired level of
compression. The higher the number you specify, the less your bitmap is compressed (that is,
100 indicates no compression).
Movie Setting is usually the default compression setting, except under certain conditions when
the compression feature is disabled or when Director controls image-compression choices.
For example, when the image is a JPEG, the compression setting defaults to JPEG compression.
You cannot select another compression option.
