Displaces an image's colormap by a given number of positions. If you cycle the colormap a number of times you can produce a psychodelic effect.
This method runs inside an isolate different from the main isolate.
Implementation
Future<bool> magickCycleColormapImage(int displace) async =>
await _magickCompute(
_magickCycleColormapImage,
_MagickCycleColormapImageParams(_wandPtr.address, displace),
);
