_quality (Button._quality property)

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.

Availability: ActionScript 1.0; Flash Player 6

Example
