4. For Dimensions, enter a width and height in pixels for the exported bitmap image, or select
Match Movie to make the JPEG image the same size as the Stage and maintain the aspect
ratio of your original image.
5. For Quality, drag the slider or enter a value to control the amount of JPEG file
compression.
The lower the image quality, the smaller the file size, and vice versa. Try different settings
to determine the best compromise between size and quality.
6. Select Progressive to show Progressive JPEG images incrementally in a web browser, which
makes images appear faster when loading with a slow network connection.
This option is similar to interlacing in GIF and PNG images.
7. To save the settings with the current file, click OK.
Specifying publish settings for PNG files
PNG is the only cross-platform bitmap format that supports transparency (an alpha channel).
It is also the native file format for Macromedia Fireworks.
Flash exports the first frame in the SWF file as a PNG file, unless you mark a different
keyframe for export by entering the frame label
#Static .
To publish a PNG file with your Flash SWF file:
1. Do one of the following to open the Publish Settings dialog box:
■
Select File > Publish Settings.
■
In the Property inspector for the document (which is available when no object is
selected), click the Settings button.
2. On the Formats tab, select the PNG Image type. For the PNG filename, either use the
default filename, or enter a new filename with the .png extension.
3.
Click the PNG tab. For Dimensions, enter values for width and height in pixels for the
exported bitmap image, or select Match Movie to make the PNG image the same size as
the Flash SWF file and maintain the aspect ratio of your original image.
