option, and enter a value between 1 and 100 in the Quality text field. (A higher setting preserves greater image
integrity but yields a larger file size.).

Lossless (PNG/GIF) compresses the image with lossless compression, in which no data is discarded from
Lossless
the image.
Note: Use Lossy 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.
Determines the number of bitmaps that are created for a given layer based on your import

selections, and the compressed size in kilobytes of the resulting bitmaps on the layer. For example, if you select a layer
with a drop shadow and a blur, and maintain layer styles, the Calculate Bitmap Size information states that three
bitmaps will result from the import—one for each filter effect, and another for the image itself. To calculate the size
of all the bitmaps to be imported, select all of the layers and click Calculate Bitmap Size.
Imported bitmaps
Working with imported bitmaps
When you import a bitmap into Flash, you can modify that bitmap and use it in your Flash document in a variety of ways.
If a Flash document displays an imported bitmap at a size larger than the original, the image may be distorted. To be
sure that images are displayed properly, preview imported bitmaps.
Use the Property inspector to work with bitmaps
When you select a bitmap on the Stage, the Property inspector displays the bitmap's symbol name and its pixel
dimensions and position on the Stage. Using the Property inspector, you can swap an instance of a bitmap—that is,
replace the instance with an instance of another bitmap in the current document.
Display the Property inspector with bitmap properties
1
Select an instance of a bitmap on the Stage.
Select Window > Properties > Properties.

Replace an instance of a bitmap with an instance of another bitmap
Select a bitmap instance on the Stage.
1
Select Window > Properties > Properties, and click Swap.
2
Select a bitmap to replace the one currently assigned to the instance.

Set 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.
Select a bitmap in the Library panel and click the Properties button at the bottom of the Library panel.
