ADOBE FIREWORKS CS3 274 User Guide 7 Select Preserve Text Quality. All text items will automatically be exported at a higher level, regardless of the Selective Quality value. 8 Select Preserve Button Quality. All button symbols will automatically be exported at a higher level. 9 Click OK. To modify the selective JPEG compression area: 1 Select Modify > Selective JPEG > Restore JPEG Mask as Selection. The selection is highlighted. 2 Use the Marquee tool or another selection tool to make changes to the size of the area. 3 Select Modify > Selective JPEG > Save Selection as JPEG Mask. 4 Change selective quality settings in the Optimize panel if desired. Note: To undo a selection, select Modify > Selective JPEG > Remove JPEG Mask. Blurring or sharpening detail You can set Smoothing in the Optimize panel to help decrease the file size of JPEGs. Smoothing blurs hard edges, which do not compress well in JPEGs. Higher numbers produce more blurring in the exported or saved JPEG, typically creating smaller files. A smoothing setting of about 3 reduces the size of the image while still maintaining reasonable quality. To help preserve fine edges between two colors: ❖ Select Sharpen JPEG Edges from the Optimize panel Options menu. Use Sharpen JPEG Edges when exporting or saving JPEGs with text or fine detail to preserve the sharpness of these areas. Choosing Sharpen JPEG Edges increases file size. Using progressive JPEGs Progressive JPEGs, such as interlaced GIFs and PNGs, are displayed at a low resolution initially and then increase in quality as they download. To export or save a progressive JPEG: ❖ Select Progressive JPEG from the Optimize panel Options menu. Note: Some older bitmap-editing applications cannot open progressive JPEGs. Matching a target background color Anti-aliasing makes an object appear smoother by blending the color of an object into the background on which it is placed. For example, if the object is black and the page on which it rests is white, anti-aliasing adds several shades of gray to the pixels surrounding the object's border to make a smoother transition between the black and white.

which do not compress well in JPEGs. Higher numbers produce more blurring in the exported or saved JPEG,

Using progressive JPEGs
Progressive JPEGs, such as interlaced GIFs and PNGs, are displayed at a low resolution initially and then increase in
quality as they download.
To export or save a progressive JPEG:

Some older bitmap-editing applications cannot open progressive JPEGs.
Matching a target background color
Anti-aliasing makes an object appear smoother by blending the color of an object into the background on which it
is placed. For example, if the object is black and the page on which it rests is white, anti-aliasing adds several shades
of gray to the pixels surrounding the object’s border to make a smoother transition between the black and white.
