Here is an example of MagickConstituteImage() that we confirmed works
properly with the latest release of ImageMagick:
#include <stdio.h>
#include <stdlib.h>
#include <wand/MagickWand.h>
int main(int argc,char **argv)
{
#define ThrowWandException(wand) \

*description; \
\

severity; \
\
description=MagickGetException(wand,&severity); \
(void) fprintf(stderr,"%s %s %ld %s\n",GetMagickModule(),description); \
description=(char *) MagickRelinquishMemory(description); \
exit(-1); \
}
