Specify publish settings for JPEG files
The JPEG format lets you publish a FLA file as a highly compressed, 24-bit bitmap. Generally, GIF format is better for exporting line art, and JPEG
format is better for images with continuous tones, such as photographs, gradients, or embedded bitmaps.
Flash Pro exports the first frame in the SWF file as a JPEG, unless you mark a different keyframe for export by entering the #Static frame label
in the Timeline.
1. Select File > Publish Settings, and select JPEG Image in the left column.
2. For the JPEG filename, either use the default filename, or enter a new filename with the .jpg extension.
3. Select options for the JPEG file:
Select Match Movie to make the JPEG image the same size as the Stage and maintain the aspect ratio of your original image, or
enter values for width and height in pixels for the exported bitmap image.
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 the reverse. To determine the best compromise between size and quality, try different settings.
note: To change the object’s compression setting, use the Bitmap Properties dialog box to set the bitmap export quality per object. The
default compression option in the Bitmap Properties dialog box applies the Publish Settings JPEG Quality option.
Show Progressive JPEG images incrementally in a web browser, which makes images appear faster when loading with a slow
network connection. Similar to interlacing in GIF and PNG images.
4. Click OK.
Specify 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 Adobe®
Fireworks®.
Flash Pro exports the first frame in the SWF file as a PNG file, unless you mark a different keyframe for export by entering the #Static frame
label in the Timeline.
1. Select File > Publish Settings, and select PNG Image in the left column.
2. For the PNG filename, either use the default filename, or enter a new filename with the .png extension.
3. For Size, select Match Movie to make the PNG image the same size as the SWF file and maintain the aspect ratio of your original image, or
enter values for Width and Height in pixels for the exported bitmap.
4. For Bit Depth, set the number of bits per pixel and colors to use in creating the image. The higher the bit depth, the larger the file.
