The MagickWand API is the recommended interface between the C programming language and the ImageMagick image processing libraries. Unlike the MagickCore C API, MagickWand uses only a few opaque types. Accessors are available to set or get important wand attributes. A description of the MagickWand public methods are found here: Magick Wand Methods Set or Get Magick Wand Attributes Magick Wand Image Methods Pixel Iterator Methods Pixel Wand Methods Image Vector Drawing After you write your MagickWand program, compile it like this:
      cc `Wand-config --cflags --cppflags` wand.c `Wand-config --ldflags --libs`
Here is a example program that utilizes the MagickWand API to get you started, wand.c. It reads a GIF image, creates a thumbnail, and writes it to disk in the PNG image format.
      #include <stdio.h>
      #include <wand/MagickWand.h>

      int main(int argc,char **argv)
      {
      #define ThrowWandException(wand) \
      { \
        char \
          *description; \
       \
        ExceptionType \
          severity; \
       \
        description=MagickGetException(wand,&severity); \
        (void) fprintf(stderr,"%s %s %ld %s\n",GetMagickModule(),description); \
        description=(char *) MagickRelinquishMemory(description); \
        exit(-1); \
      }

        MagickBooleanType
          status;

        MagickWand
          *magick_wand;

        /*
          Read an image.
        */
        MagickWandGenesis();
        magick_wand=NewMagickWand();
        status=MagickReadImage(magick_wand,"image.gif");
        if (status == MagickFalse)
          ThrowWandException(magick_wand);
        /*
          Turn the images into a thumbnail sequence.
        */
        MagickResetIterator(magick_wand);
        while (MagickNextImage(magick_wand) != MagickFalse)
          MagickResizeImage(magick_wand,106,80,LanczosFilter,1.0);
        /*
          Write the image as MIFF and destroy it.
        */
        status=MagickWriteImages(magick_wand,"image.png",MagickTrue);
        if (status == MagickFalse)
          ThrowWandException(magick_wand);
        magick_wand=DestroyMagickWand(magick_wand);
        MagickWandTerminus();
        return(0);
      }
