ImageMagick: MagickCore, C API for ImageMagick: The Registry
Author: ImageMagick Studio LLC
Description: ImageMagick (TM) is a free software suite to create, edit and compose bitmap images. It can read, convert and write images in a large variety of formats. Images can be cropped, colors can be changed, various effects can be applied, images can be rotated and combined, and text, lines, polygons, ellipses and Bézier curves can be added to images and stretched and rotated. ImageMagick is free software: it is delivered with full source code and can be freely used, copied, modified and distributed. Its license is compatible with the GPL. It runs on all major operating systems. Most of the functionality of ImageMagick can be used interactively from the command line; more often, however, the features are used from programs written in the programming languages Perl, C, C++, Python, PHP, Ruby or Java, for which ready-made ImageMagick interfaces (PerlMagick, Magick++, PythonMagick, MagickWand for PHP, RubyMagick, and JMagick) are available. This makes it possible to modify or create images automa [cell cut: 1159 characters, first 1000 kept]

## DeleteMagickRegistry DeleteMagickRegistry() deletes an entry in the registry as defined by the id. It returns MagickTrue if the entry is deleted otherwise MagickFalse if no entry is found in the registry that matches the id. The format of the DeleteMagickRegistry method is:
      MagickBooleanType DeleteMagickRegistry(const long id)
A description of each parameter follows: #### id The registry id. ## GetImageFromMagickRegistry GetImageFromMagickRegistry() gets an image from the registry as defined by its name. If the blob that matches the name is not found, NULL is returned. The format of the GetImageFromMagickRegistry method is:
      Image *GetImageFromMagickRegistry(const char *name,long *id,
        ExceptionInfo *exception)
A description of each parameter follows: #### name The name of the image to retrieve from the registry. #### id The registry id. #### exception Return any errors or warnings in this structure. ## GetMagickRegistry GetMagickRegistry() gets a blob from the registry as defined by the id. If the blob that matches the id is not found, NULL is returned. The format of the GetMagickRegistry method is:
      const void *GetMagickRegistry(const long id,RegistryType *type,
        size_t *length,ExceptionInfo *exception)
A description of each parameter follows: #### id The registry id. #### type The registry type. #### length The blob length in number of bytes. #### exception Return any errors or warnings in this structure. ## SetMagickRegistry SetMagickRegistry() sets a blob into the registry and returns a unique ID. If an error occurs, -1 is returned. The format of the SetMagickRegistry method is:
      long SetMagickRegistry(const RegistryType type,const void *blob,
        const size_t length,ExceptionInfo *exception)
A description of each parameter follows: #### type The registry type. #### blob The address of a Binary Large OBject. #### length For a registry type of ImageRegistryType use sizeof(Image) otherise the blob length in number of bytes. #### exception Return any errors or warnings in this structure. |
