Additional Comments
Expander triangle

Use the screenGamma property to control the color display of PNG images.

Value:

The screenGamma is a number.

Comments:

PNG images can contain a preferred gamma setting. To display a PNG to best advantage, you may need to adjust the screenGamma property to match what the PNG expects.

Changes in the screenGamma do not apply to PNG images that are already displayed. A PNG image uses the screenGamma that was in effect when it was being decompressed for display.

Tip: To force Revolution to re-decompress a PNGimage without leaving the card, put the image into itself:

set the screenGamma to 2.2

put image "Test PNG" into image "Test PNG"
