IMImage7MBS.AuthenticPixels(X as Integer, Y as Integer, Width as Integer, Height as Integer) as Ptr

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

Obtains a pixel region for read/write access.

If the region is successfully accessed, a pointer to a Quantum array representing the region is returned, otherwise NULL is returned.

The returned pointer may point to a temporary working copy of the pixels or it may point to the original pixels in memory. Performance is maximized if the selected region is part of one row, or one or more full rows, since then there is opportunity to access the pixels in-place (without a copy) if the image is in memory, or in a memory-mapped file. The returned pointer must *never* be deallocated by the user.

Pixels accessed via the returned pointer represent a simple array of type Quantum. If the image has corresponding metacontent,call GetAuthenticMetacontent() after invoking GetAuthenticPixels() to obtain the meta-content corresponding to the region. Once the Quantum array has been updated, the changes must be saved back to the underlying image using SyncAuthenticPixels() or they may be lost.

See xx function in ImageMagick documentation.

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

Replaces each color value in the given image, by using it as an index to lookup a replacement color value in a Color Look UP Table in the form of an image.

The values are extracted along a diagonal of the CLUT image so either a horizontal or vertial gradient image can be used.

Typically this is used to either re-color a gray-scale image according to a color gradient in the CLUT image, or to perform a freeform histogram (level) adjustment according to the (typically gray-scale) gradient in the CLUT image.

When the 'channel' mask includes the matte/alpha transparency channel but one image has no such channel it is assumed that that image is a simple gray-scale image that will effect the alpha channel values, either for gray-scale coloring (with transparent or semi-transparent colors), or a histogram adjustment of existing alpha channel values. If both images have matte channels, direct and normal indexing is applied, which is rarely used.

clutImage: the color lookup table image for replacement color values.
method: the pixel interpolation method.

See ClutImage function in ImageMagick documentation.

method	ImageMagick7	MBS GraphicsMagick Plugin	20.0	✅ Yes	✅ Yes	✅ Yes	✅ Yes	All

Compares each image with the next in a sequence and returns the minimum bounding region of all the pixel differences (of the LayerMethod specified) it discovers.

Images do NOT have to be the same size, though it is best that all the images are 'coalesced' (images are all the same size, on a flattened canvas, so as to represent exactly how an specific frame should look).

No GIF dispose methods are applied, so GIF animations must be coalesced before applying this image operator to find differences to them.

method: the layers type to compare images with. Must be one of... CompareAnyLayer, CompareClearLayer, CompareOverlayLayer.

See xx function in ImageMagick documentation.

IMImage7MBS.ComplexImages(ComplexOperator as Integer) as IMImage7MBS

IMImage7MBS.Composite(ComposeOperator as integer, Image as IMImage7MBS, ClipToSelf as boolean, xOffset as integer, yOffset as integer)

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

See xx function in ImageMagick documentation.

IMImage7MBS.CompositeLayers(CompositeOperator as Integer, Source as IMImage7MBS, XOffset as Integer, YOffset as Integer)

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

Compose the source image sequence over the destination image sequence, starting with the current image in both lists.

Each layer from the two image lists are composted together until the end of one of the image lists is reached. The offset of each composition is also adjusted to match the virtual canvas offsets of each layer. As such the given offset is relative to the virtual canvas, and not the actual image.

Composition uses given x and y offsets, as the 'origin' location of the source images virtual canvas (not the real image) allowing you to compose a list of 'layer images' into the destiantioni images. This makes it well sutiable for directly composing 'Clears Frame Animations' or 'Coaleased Animations' onto a static or other 'Coaleased Animation' destination image list. GIF disposal handling is not looked at.

Special case:- If one of the image sequences is the last image (just a single image remaining), that image is repeatally composed with all the images in the other image list. Either the source or destination lists may be the single image, for this situation.

In the case of a single destination image (or last image given), that image will ve cloned to match the number of images remaining in the source image list.

This is equivelent to the "-layer Composite" Shell API operator.

See xx function in ImageMagick documentation.
