Using Bitmaps in Flash 8
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 set bitmap properties:
Select a bitmap in the Library panel. If you don’t have one – import one in.
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 select Properties from
the context menu.
Select Properties from the options menu in the upper right corner of the Library panel.
In the Bitmap Properties dialog box, select Allow Smoothing to smooth the edges of the bitmap
with anti-aliasing.
For Compression, select one of the following options:
Photo (JPEG) compresses 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.)
6. Lossless (PNG/GIF) compresses 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.
7. 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.
8. 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.
