magickConstituteImageFromLongPixel method

Future<bool> magickConstituteImageFromLongPixel({ required int columns, required int rows, required String map, required Uint32List pixels, })

Adds an image to the wand comprised of the pixel data you supply. The pixel data must be in scanline order top-to-bottom.

This method runs inside an isolate different from the main isolate.

• columns: width in pixels of the image.

• rows: height in pixels of the image.

• map: This string reflects the expected ordering of the pixel array. It can be any combination or order of R = red, G = green, B = blue, A = alpha (0 is transparent), O = alpha (0 is opaque), C = cyan, Y = yellow, M = magenta, K = black, I = intensity (for grayscale), P = pad.

• pixels: A Uint32List of values contain the pixel components as defined by map.

Sending invalid parameters will cause an invalid state and may crash the app, so you should make sure to validate the input to this method.
