Author: ImageMagick Studio LLC
Description: ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you can freely use, copy, modify, and distribute. Its license is compatible with the GPL. It runs on all major operating systems. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: MagickCore (C), MagickWand (C), ChMagick (Ch), Magick++ (C++), JMagick (Java), L-Magick (Lisp), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (P [cell cut: 1167 characters, first 1000 kept]

## AppendImageToList AppendImageToList() appends the second image list to the end of the first list. The given image list pointer is left unchanged, unless it was empty. The format of the AppendImageToList method is:
      AppendImageToList(Image *images,const Image *image)
A description of each parameter follows: ##### images The image list to be appended to. ##### image The appended image or image list. ## CloneImageList CloneImageList() returns a duplicate of the image list. The format of the CloneImageList method is:
      Image *CloneImageList(const Image *images,ExceptionInfo *exception)
A description of each parameter follows: ##### images The image list. ##### exception Return any errors or warnings in this structure. ## CloneImages CloneImages() clones one or more images from an image sequence, using a comma separated list of image numbers or ranges. The numbers start at 0 for the first image in the list, while negative numbers refer to images starting counting from the end of the range. Images may be refered to multiple times to clone them multiple times. Images refered beyond the available number of images in list are ignored. Images referenced may be reversed, and results in a clone of those images also being made with a reversed order. The format of the CloneImages method is:
      Image *CloneImages(const Image *images,const char *scenes,
        ExceptionInfo *exception)
A description of each parameter follows: ##### images The image sequence. ##### scenes This character string specifies which scenes to clone (e.g. 1,3-5,7-3,2). ##### exception Return any errors or warnings in this structure. ## DeleteImageFromList DeleteImageFromList() deletes an image from the list. List pointer is moved to the next image, if one is present. See RemoveImageFromList(). The format of the DeleteImageFromList method is:
      DeleteImageFromList(Image **images)
A description of each parameter follows: ##### images The image list. ## DeleteImages DeleteImages() deletes one or more images from an image sequence, using a comma separated list of image numbers or ranges. The numbers start at 0 for the first image, while negative numbers refer to images starting counting from the end of the range. Images may be refered to multiple times without problems. Image refered beyond the available number of images in list are ignored. If the referenced images are in the reverse order, that range will be completely ignored. Unlike CloneImages(). The format of the DeleteImages method is:
      DeleteImages(Image **images,const char *scenes,ExceptionInfo *exception)
A description of each parameter follows: ##### images The image sequence. ##### scenes This character string specifies which scenes to delete (e.g. 1,3-5,-2-6,2). ##### exception Return any errors or warnings in this structure. ## DestroyImageList DestroyImageList() destroys an image list. The format of the DestroyImageList method is:
      Image *DestroyImageList(Image *image)
A description of each parameter follows: ##### image The image sequence. ## GetFirstImageInList GetFirstImageInList() returns a pointer to the first image in the list. The format of the GetFirstImageInList method is:
      Image *GetFirstImageInList(const Image *images)
A description of each parameter follows: ##### images The image list. ## GetImageFromList GetImageFromList() returns an image at the specified offset from the list. The format of the GetImageFromList method is:
      Image *GetImageFromList(const Image *images,const long index)
A description of each parameter follows: ##### images The image list. ##### index The position within the list. ## GetImageIndexInList GetImageIndexInList() returns the offset in the list of the specified image. The format of the GetImageIndexInList method is:
      long GetImageIndexInList(const Image *images)
A description of each parameter follows: ##### images The image list. ## GetImageListLength GetImageListLength() returns the length of the list (the number of images in the list). The format of the GetImageListLength method is:
      unsigned long GetImageListLength(const Image *images)
A description of each parameter follows: ##### images The image list. ## GetLastImageInList GetLastImageInList() returns a pointer to the last image in the list. The format of the GetLastImageInList method is:
      Image *GetLastImageInList(const Image *images)
A description of each parameter follows: ##### images The image list. ## GetNextImageInList GetNextImageInList() returns the next image in the list. The format of the GetNextImageInList method is:
      Image *GetNextImageInList(const Image *images)
A description of each parameter follows: ##### images The image list. ## GetPreviousImageInList GetPreviousImageInList() returns the previous image in the list. The format of the GetPreviousImageInList method is:
      Image *GetPreviousImageInList(const Image *images)
A description of each parameter follows: ##### images The image list. ## ImageListToArray ImageListToArray() is a convenience method that converts an image list to a sequential array. For example, group = ImageListToArray(images, exception); while (i = 0; group[i] != (Image *) NULL; i++) printf("s\n", group[i]->filename); printf("d images\n", i); group = RelinquishMagickMemory(group); The format of the ImageListToArray method is:

      Image *RemoveImageFromList(Image **images)
A description of each parameter follows: ##### images The image list. ## RemoveFirstImageFromList RemoveFirstImageFromList() removes and returns the first image in the list. If the given image list pointer pointed to the removed first image, it is set to the new first image of list, or NULL if list was emptied, otherwise it is left as is.

The format of the RemoveLastImageFromList method is:
      Image *RemoveLastImageFromList(Image **images)
A description of each parameter follows: ##### images The image list. ## ReplaceImageInList ReplaceImageInList() replaces an image in the list. Old image is destroyed. The given image list pointer is set to point to the just inserted image. The format of the ReplaceImageInList method is:
      ReplaceImageInList(Image **images,Image *image)
A description of each parameter follows: ##### images The image list. ##### image The image. ## ReverseImageList ReverseImageList() reverses the order of an image list. The list pointer is reset to that start of the re-ordered list. The format of the ReverseImageList method is:
