JPEG (an acronym for Joint Photographic Experts Group) is a commonly used image format that involves lossy compression when exporting images with photographic content. The degree of compression can be adjusted by choosing varying percentages of image quality, allowing you to obtain the desired balance between file size and pixel detail in the exported image. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.
JPEG is the most common image format used by digital cameras and other photographic devices. Bitmap graphics are commonly exported in the JPEG format prior to being inserted in web pages.
To bring JPEG (and other image files) into an Adobe Flash Professional project and display them on the Stage, choose File > Import > Import to Stage. Once the files are imported, they are displayed as bitmap graphics in the Library.
To export a JPEG screenshot of the current frame of the project, choose File > Publish Settings and click the check box next to JPEG. You can adjust the publish profile to control the export settings used to generate the published JPEG file.
You can convert JPEG files and other bitmap graphics into symbols, and then use the Property inspector to apply color effects.
To learn more about working with JPEG files, see the section titled Exporting images and graphics in the Flash documentation.
