## MagickCompositeLayers

MagickCompositeLayers() composite the images in the source wand over the images in the destination wand in 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 destination images. This makes it well suitable for directly composing 'Clears Frame Animations' or 'Coalesced Animations' onto a static or other 'Coalesced 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 repeatedly composed with all the images in the other image list. Either the source or destination lists may be the single image, for this situation.

image
  the image.
threshold_map
  A string containing the name of the threshold dither map to use, followed by zero or more numbers representing the number of color levels tho dither between.
  Any level number less than 2 is equivalent to 2, and means only binary dithering will be applied to each color channel.
  No numbers also means a 2 level (bitmap) dither will be applied to all channels, while a single number is the number of levels applied to each channel in sequence. More numbers will be applied in turn to each of the color channels.
  For example: "o3x3,6" generates a 6 level posterization of the image with a ordered 3x3 diffused pixel dither being applied between each level. While checker,8,8,4 will produce a 332 colormaped image with only a single checkerboard hash pattern (50 grey) between each color level, to basically double the number of color levels with a bare minimum of dithering.

## MagickVignetteImage

MagickVignetteImage() softens the edges of the image in vignette style.

The format of the MagickVignetteImage method is:

    MagickBooleanType MagickVignetteImage(MagickWand *wand,
      const double radius,const double sigma,const ssize_t x,
      const ssize_t y)

A description of each parameter follows:

wand
  the magick wand.
radius
  the radius.
sigma
  the sigma.
x, y
  Define the x and y ellipse offset.

## MagickWaveImage

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,
      const PixelInterpolateMethod method)

A description of each parameter follows:

wand
  the magick wand.
amplitude, wave_length
  Define the amplitude and wave length of the sine wave.
method
  the pixel interpolation method.

## MagickWaveletDenoiseImage

MagickWaveletDenoiseImage() removes noise from the image using a wavelet transform. The wavelet transform is a fast hierarchical scheme for processing an image using a set of consecutive lowpass and high_pass filters, followed by a decimation. This results in a decomposition into different scales which can be regarded as different “frequency bands”, determined by the mother wavelet.

The format of the MagickWaveletDenoiseImage method is:

    MagickBooleanType MagickWaveletDenoiseImage(MagickWand *wand,
      const double threshold,const double softness)

A description of each parameter follows:

wand
  the magick wand.
threshold
  set the threshold for smoothing.
softness
  attenuate the smoothing threshold.

## MagickWhiteBalanceImage

MagickWhiteBalanceImage() applies white balancing to an image according to a grayworld assumption in the LAB colorspace.

The format of the WhiteBalanceImage method is:

    MagickBooleanType WhiteBalanceImage(MagickWand *wand)

A description of each parameter follows:

wand
  the magick wand.

## MagickWhiteThresholdImage

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:

wand
  the magick wand.
threshold
  the pixel wand.

## MagickWriteImage

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:

wand
  the magick wand.
filename
  the image filename.

## MagickWriteImageFile

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:

wand
  the magick wand.
file
  the file descriptor.

## MagickWriteImages

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:

wand
  the magick wand.
filename
  the image filename.
adjoin
  join images into a single multi-image file.

## MagickWriteImagesFile

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:

wand
  the magick wand.
file
  the file descriptor.
