GMImage.RandomThreshold
Component: GraphicsMagick
Version: 2.0
Mac OS X: Works
Windows: Works
MBS( "GMImage.RandomThreshold"; ImageRef; thresholds )
Parameters
| Parameter | Description | Example value |
|---|---|---|
| ImageRef | The image reference (a number returned from the GMImage.New functions) | 1 |
| thresholds | The rectangle. Geometry is specified as a width and height "100x200". With an optional offset "100x200+10+20". For percent values, add a percent on the end, for % values add a %: "100x200%!" | "100x200" |
Result
Returns "OK" on success.
Description
Random threshold image.Changes the value of individual pixels based on the intensity of each pixel compared to a random threshold. The result is a low-contrast, two color image. The thresholds_ argument is a geometry containing LOWxHIGH thresholds. If the string contains 2x2, 3x3, or 4x4, then an ordered dither of order 2, 3, or 4 will be performed instead. If a ChannelType argument is specified then only the specified channel is altered. This is a very fast alternative to 'quantize' based dithering.
