Chop
Chop() removes a region of an image and collapses the image to occupy the removed portion.
The format of the ChopImage method is:
Image *ChopImage(const Image *image,const RectangleInfo *chop_info)
ExceptionInfo *exception)
A description of each parameter follows:
image
The image.
chop_info
Define the region of the image to chop.
exception
Return any errors or warnings in this structure.
CoalesceImages
CoalesceImages() composites a set of images while respecting any page offsets and disposal methods.  GIF, MIFF, and MNG animation sequences typically start with an image background and each subsequent image varies in size and offset.  CoalesceImages() returns a new sequence where each image in the sequence is the same size as the first and composited with the next image in the sequence.
The format of the CoalesceImages method is:
Image *CoalesceImages(const Image *image,ExceptionInfo *exception)
A description of each parameter follows:
image
The image sequence.
exception
Return any errors or warnings in this structure.
CropImage
CropImage() extracts a region of the image starting at the offset defined by geometry.
The format of the CropImage method is:
Image *CropImage(const Image *image,const RectangleInfo *geometry,
ExceptionInfo *exception)
A description of each parameter follows:
image
The image.
geometry
Define the region of the image to crop with members x, y, width, and height.
exception
Return any errors or warnings in this structure.
DeconstructImages
DeconstructImages() compares each image with the next in a sequence and returns the maximum bounding region of any pixel differences it discovers.
The format of the DeconstructImages method is:
Image *DeconstructImages(const Image *image,ExceptionInfo *exception)
A description of each parameter follows:
image
The image.
exception
Return any errors or warnings in this structure.
FlattenImage
FlattenImage() merges a sequence of images.  This is useful for combining Photoshop layers into a single image.
The format of the FlattenImage method is:
Image *FlattenImage(const Image *image,ExceptionInfo *exception)
A description of each parameter follows:
image
The image sequence.
exception
Return any errors or warnings in this structure.
FlipImage
FlipImage() creates a vertical mirror image by reflecting the pixels around the central x-axis.
The format of the FlipImage method is:
Image *FlipImage(const Image *image,ExceptionInfo *exception)
A description of each parameter follows:
image
The image.
exception
Return any errors or warnings in this structure.
FlopImage
FlopImage() creates a horizontal mirror image by reflecting the pixels around the central y-axis.
The format of the FlopImage method is:
Image *FlopImage(const Image *image,ExceptionInfo *exception)
A description of each parameter follows:
image
The image.
exception
Return any errors or warnings in this structure.
MosaicImages
MosaicImages() inlays an image sequence to form a single coherent picture. It returns a single image with each image in the sequence composited at the location defined by the page member of the image structure.
The format of the MosaicImage method is:
Image *MosaicImages(const Image *image,ExceptionInfo *exception)
A description of each parameter follows:
image
The image.
exception
Return any errors or warnings in this structure.
RollImage
RollImage() offsets an image as defined by x_offset and y_offset.
The format of the RollImage method is:
Image *RollImage(const Image *image,const long x_offset,
const long y_offset,ExceptionInfo *exception)
A description of each parameter follows:
image
The image.
x_offset
The number of columns to roll in the horizontal direction.
y_offset
The number of rows to roll in the vertical direction.
exception
Return any errors or warnings in this structure.
ShaveImage
ShaveImage() shaves pixels from the image edges.  It allocates the memory necessary for the new Image structure and returns a pointer to the new image.
The format of the ShaveImage method is:
Image *ShaveImage(const Image *image,const RectangleInfo *shave_info,
ExceptionInfo *exception)
A description of each parameter follows:
shave_image
Method ShaveImage returns a pointer to the shaved image.  A null image is returned if there is a memory shortage or if the image width or height is zero.
image
The image.
shave_info
Specifies a pointer to a RectangleInfo which defines the region of the image to crop.
exception
Return any errors or warnings in this structure.
SpliceImage
SpliceImage() splices a solid color into the image as defined by the geometry.
The format of the SpliceImage method is:
Image *SpliceImage(const Image *image,const RectangleInfo *geometry,
ExceptionInfo *exception)
A description of each parameter follows:
image
The image.
geometry
Define the region of the image to splice with members x, y, width, and height.
exception
Return any errors or warnings in this structure.
TransformImage
TransformImage() is a convenience method that behaves like ResizeImage() or CropImage() but accepts scaling and/or cropping information as a region geometry specification.  If the operation fails, the original image handle is returned.
The format of the TransformImage method is:
MagickBooleanType TransformImage(Image **image,const char *crop_geometry,
const char *image_geometry)
A description of each parameter follows:
image
The image The transformed image is returned as this parameter.
crop_geometry
A crop geometry string.  This geometry defines a subregion of the image to crop.
image_geometry
An image geometry string.  This geometry defines the final size of the image.
TransformImages
TransformImages() calls TransformImage() on each image of a sequence.
The format of the TransformImage method is:
MagickBooleanType TransformImages(Image **image,
const char *crop_geometry,const char *image_geometry)
A description of each parameter follows:
image
The image The transformed image is returned as this parameter.
crop_geometry
A crop geometry string.  This geometry defines a subregion of the image to crop.
image_geometry
An image geometry string.  This geometry defines the final size of the image.
TrimImage
TrimImage() trims pixels from the image edges.  It allocates the memory necessary for the new Image structure and returns a pointer to the new image.
The format of the TrimImage method is:
Image *TrimImage(const Image *image,ExceptionInfo *exception)
A description of each parameter follows:
image
The image.
exception
Return any errors or warnings in this structure.
