If the operation fails, the original image handle is returned. The format of the MagickTransformImage method is: MagickWand *MagickTransformImage ( MagickWand *wand, const char *crop, const char *geometry ); A description of each parameter follows: wand: The magick wand. crop: A crop geometry string. This geometry defines a subregion of the image to crop. geometry: An image geometry string. This geometry defines the final size of the image. ## MagickTrimImage MagickTrimImage() remove edges that are the background color from the image. The format of the MagickTrimImage method is: MagickBooleanType MagickTrimImage ( MagickWand *wand, const double fuzz ); A description of each parameter follows: wand: The magick wand. fuzz: By default target must match a particular pixel color exactly. However, in many cases two colors may differ by a small amount. The fuzz member of image defines how much tolerance is acceptable to consider two colors as the same. For example, set fuzz to 10 and the color red at intensities of 100 and 102 respectively are now interpreted as the same color for the purposes of the floodfill. ## MagickUnsharpMaskImage 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 ); A description of each parameter follows: wand: The magick wand. radius: The radius of the Gaussian, in pixels, not counting the center pixel. sigma: The standard deviation of the Gaussian, in pixels. amount: The percentage of the difference between the original and the blur image that is added back into the original. threshold: The threshold in pixels needed to apply the diffence amount. ## MagickUnsharpMaskImageChannel MagickUnsharpMaskImageChannel() sharpens one or more image channels. 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 MagickUnsharpMaskImageChannel method is: 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: wand: The magick wand. channel: Identify which channel to extract: RedChannel, GreenChannel, BlueChannel, OpacityChannel, CyanChannel, MagentaChannel, YellowChannel, BlackChannel, or IndexChannel. radius: The radius of the Gaussian, in pixels, not counting the center pixel. sigma: The standard deviation of the Gaussian, in pixels. amount: The percentage of the difference between the original and the blur image that is added back into the original. threshold: The threshold in pixels needed to apply the diffence amount. ## 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 ); A description of each parameter follows: wand: The magick wand. amplitude, wave_length: Define the amplitude and wave length of the sine wave. ## MagickWhiteThresholdImage MagickWhiteThresholdImage() is like ThresholdImage ( ) but forces 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. ## NewMagickWand NewMagickWand() returns a wand required for all other methods in the API. The format of the NewMagickWand method is: MagickWand NewMagickWand ( void ); ## NewMagickWandFromImage `NewMagickWandWithImage()` returns a wand with an image. The format of the NewMagickWandWithImage method is:
        MagickWand NewMagickWandWithImage(const Image *image)
A description of each parameter follows: image: The image. "Image manipulation software that works like magick"
