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.

The format of the MagickTransformImageColorspace method is:
MagickBooleanType MagickTransformImageColorspace(MagickWand *wand, const ColorspaceType colorspace)
A description of each parameter follows:
MagickTransparentPaintImage() changes any pixel that matches color with the color defined by fill.
The format of the MagickTransparentPaintImage method is:
MagickBooleanType MagickTransparentPaintImage(MagickWand *wand, const PixelWand *target,const double alpha,const double fuzz, const MagickBooleanType invert)
A description of each parameter follows:
MagickTransposeImage() creates a vertical mirror image by reflecting the pixels around the central x-axis while rotating them 90-degrees.
The format of the MagickTransposeImage method is:
MagickBooleanType MagickTransposeImage(MagickWand *wand)
A description of each parameter follows:
MagickTransverseImage() creates a horizontal mirror image by reflecting the pixels around the central y-axis while rotating them 270-degrees.
The format of the MagickTransverseImage method is:
MagickBooleanType MagickTransverseImage(MagickWand *wand)
A description of each parameter follows:
MagickTrimImage() remove edges that are the background color from the image.

MagickBooleanType MagickTrimImage(MagickWand *wand,const double fuzz)
A description of each parameter follows:
MagickUniqueImageColors() discards all but one of any pixel color.
The format of the MagickUniqueImageColors method is:
MagickBooleanType MagickUniqueImageColors(MagickWand *wand)
A description of each parameter follows:
MagickUnsharpMaskImage() sharpens an image. We convolve the image with a Gaussian operator of the given radius and standard deviation (sigma). For reasonable results, radius should be larger than sigma. Use a radius of 0 and UnsharpMaskImage() selects a suitable radius for you.
The format of the MagickUnsharpMaskImage method is:
MagickBooleanType MagickUnsharpMaskImage(MagickWand *wand, const double radius,const double sigma,const double amount, const double threshold) MagickBooleanType MagickUnsharpMaskImageChannel(MagickWand *wand, const ChannelType channel,const double radius,const double sigma, const double amount,const double threshold)
A description of each parameter follows:
MagickVignetteImage() softens the edges of the image in vignette style.
The format of the MagickVignetteImage method is:
MagickBooleanType MagickVignetteImage(MagickWand *wand, const double black_point,const double white_point,const ssize_t x, const ssize_t y)
A description of each parameter follows:
MagickWaveImage() creates a "ripple" effect in the image by shifting the pixels vertically along a sine wave whose amplitude and wavelength is specified by the given parameters.
The format of the MagickWaveImage method is:
MagickBooleanType MagickWaveImage(MagickWand *wand,const double amplitude, const double wave_length)
A description of each parameter follows:
MagickWhiteThresholdImage() is like ThresholdImage() but force all pixels above the threshold into white while leaving all pixels below the threshold unchanged.
The format of the MagickWhiteThresholdImage method is:
MagickBooleanType MagickWhiteThresholdImage(MagickWand *wand, const PixelWand *threshold)
A description of each parameter follows:
MagickWriteImage() writes an image to the specified filename. If the filename parameter is NULL, the image is written to the filename set by MagickReadImage() or MagickSetImageFilename().
The format of the MagickWriteImage method is:
MagickBooleanType MagickWriteImage(MagickWand *wand, const char *filename)
A description of each parameter follows:
MagickWriteImageFile() writes an image to an open file descriptor.
The format of the MagickWriteImageFile method is:
MagickBooleanType MagickWriteImageFile(MagickWand *wand,FILE *file)
A description of each parameter follows:
MagickWriteImages() writes an image or image sequence.
The format of the MagickWriteImages method is:
MagickBooleanType MagickWriteImages(MagickWand *wand, const char *filename,const MagickBooleanType adjoin)
A description of each parameter follows:
MagickWriteImagesFile() writes an image sequence to an open file descriptor.
The format of the MagickWriteImagesFile method is:
MagickBooleanType MagickWriteImagesFile(MagickWand *wand,FILE *file)
A description of each parameter follows:
