Overview |
Refer to Changing Brightness and Contrast. |
Remarks
Increases or decreases the contrast of the image in a bitmap, using a histogram to determine the median brightness.
This method finds the median brightness of the image; then brightens the pixels with values above the median and darkens the pixels with values below the median. This is more sophisticated (but slower) than the Contrast method, which uses the middle possible value (128) rather than finding the actual median.
This method supports 12 and 16-bit grayscale images and 48 and 64-bit color images. Support for 12 and 16-bit grayscale images and 48 and 64-bit color images is available only in the Document/Medical toolkits.
