Specifying publish settings for JPEG files
The JPEG format lets you save an image 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 exports the first frame in the SWF file as a JPEG, unless you mark a different keyframe for
export by entering the frame label #Static.
To publish a JPEG file with your Flash SWF file:
Do one of the following to open the Publish Settings dialog box:
1.
Select File > Publish Settings.
In the Property inspector for the document (which is available when no object is selected),
click the Settings button.
Note: To create a publish profile for the publish settings that you specify, see
profiles" on page
On the Formats tab, select the JPEG Image type. For the JPEG filename, either use the default
2.
filename, or enter a new filename with the .jpg extension.
Click the JPEG panel to show its settings.
3.
For Dimensions, enter a width and height in pixels for the exported bitmap image, or select
4.
Match Movie to make the JPEG image the same size as the Stage and maintain the aspect ratio
of your original image.
For Quality, drag the slider or enter a value to control the amount of JPEG file compression.
5.
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.
Note: You can set the bitmap export quality per object using the Bitmap Properties dialog box to
change the object's compression setting. Selecting the default compression option in the Bitmap
Properties dialog box applies the Publish Settings JPEG Quality option. For more information, see
"Setting bitmap properties" on page
Select Progressive to show Progressive JPEG images incrementally in a web browser, which
6.
makes images appear faster when loading with a slow network connection.
This option is similar to interlacing in GIF and PNG images.
To save the settings with the current file, click OK.
7.
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.
