property GraphicsMagick MBS GraphicsMagick Plugin 9.3 Yes Yes Yes Yes No
Function: Associate a clip mask image with the current image.
Notes:
The clip mask image must have the same dimensions as the current image or an exception is thrown. Clipping occurs wherever pixels are transparent in the clip mask image. Clipping Pass an invalid image to unset an existing clip mask.

GMImageMBS.colorMapSize as UInt32
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
property GraphicsMagick MBS GraphicsMagick Plugin 9.3 Yes Yes Yes Yes No
Function: Number of entries in the colormap.
Notes:
Setting the colormap size may extend or truncate the colormap. The maximum number of supported entries is specified by the MaxColormapSize constant, and is dependent on the value of QuantumDepth when GraphicsMagick is compiled. An exception is thrown if more entries are requested than may be supported. Care should be taken when truncating the colormap to ensure that the image colormap indexes reference valid colormap entries.

GMImageMBS.Constructor(width as UInt32, height as UInt32, map as string, StorageType as Integer, data as ptr)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method GraphicsMagick MBS GraphicsMagick Plugin 14.1 Yes Yes Yes Yes No
Function: Initializes single image frame from an array of raw pixels, with specified storage type (ConstituteImage).
Example: 
dim data as new memoryblock(2048*2048) // your data
dim image as new GMImageMBS(2048, 2048, "I", GMImageMBS.StorageTypeCharPixel, data)
Notes:
Returns an Image corresponding to an image stored in a raw memory array format. The pixel data must be in scanline order top-to-bottom. The data can be unsigned char, unsigned short int, unsigned int, unsigned long, float, or double. Float and double require the pixels to be normalized to the range [0..1], otherwise the range is [0..MaxVal] where MaxVal is the maximum possible value for that type.

Note that for most 32-bit architectures the size of an unsigned long is the same as unsigned int, but for 64-bit architectures observing the LP64 standard, an unsigned long is 64 bits, while an unsigned int remains 32 bits. This should be considered when deciding if the data should be described as "Integer" or "Long".

For example, to create a 640x480 image from unsigned red-green-blue character data, use

image = new GMImageMBS(640, 480, "RGB", GMImageMBS.StorageTypeCharPixel, pixels);

width: width in pixels of the image.
height: 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 (same as Transparency), O = Opacity, T = Transparency, C = cyan, Y = yellow, M = magenta, K = black, or I = intensity (for grayscale). Specify "P" = pad, to skip over a quantum which is intentionally ignored. Creation of an alpha channel for CMYK images is currently not supported.
type: Define the data type of the pixels. Float and double types are expected to be normalized [0..1] otherwise [0..MaxRGB]. Choose from these types: StorageTypeCharPixel, StorageTypeShortPixel, StorageTypeIntegerPixel, StorageTypeLongPixel, StorageTypeFloatPixel, or StorageTypeDoublePixel.
pixels: This array of values contain the pixel components as defined by map and type. You must preallocate this array where the expected length varies depending on the values of width, height, map, and type.
