Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	ImageMagick7	MBS GraphicsMagick Plugin	20.0	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Stretches image colors.

Uses the exact minimum and maximum values found in each of the channels given, as the BlackPoint and WhitePoint to linearly stretch the colors (and histogram) of the image. The stretch points are also moved further inward by the adjustment values given.

If the adjustment values are both zero this function is equivalent to a perfect normalization (or autolevel) of the image.

Each channel is stretched independantally of each other (producing color distortion) unless the special 'SyncChannels' flag is also provided in the channels setting. If this flag is present the minimum and maximum point will be extracted from all the given channels, and those channels will be stretched by exactly the same amount (preventing color distortion).

In the special case that only ONE value is found in a channel of the image that value is not stretched, that value is left as is.

The 'SyncChannels' is turned on in the 'DefaultChannels' setting by default.
