Button._quality
Availability
Flash Player 6.
Usage
my_btn._quality:String
Description
Property (global); sets or retrieves the rendering quality used for a SWF file. Device fonts are
always aliased and therefore are unaffected by the
_quality property.
The
_quality property can be set to the following values:
• "LOW" Low rendering quality. Graphics are not anti-aliased, and bitmaps are not smoothed.
• "MEDIUM" Medium rendering quality. Graphics are anti-aliased using a 2 x 2 pixel grid, but
bitmaps are not smoothed. This is suitable for movies that do not contain text.
• "HIGH" High rendering quality. Graphics are anti-aliased using a 4 x 4 pixel grid, and bitmaps
are smoothed if the movie is static. This is the default rendering quality setting used by Flash.
• "BEST" Very high rendering quality. Graphics are anti-aliased using a 4 x 4 pixel grid and
bitmaps are always smoothed.
Note: Although you can specify this property for a Button object, it is actually a global property, and
you can specify its value simply as
_quality. For more information, see _quality.
Example
This example sets the rendering quality of a button named my_btn to LOW:
my_btn._quality = "LOW";
