Re: MagickReadImage() sets the image filename to a tmp filename

The problem seems to be from my previous call to MagickReadImageFile(), which 
seems to set the
image filename to a temp filename.

Full program as requested:

/******************************************************/
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #include <wand/magick_wand.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 ); \
            MagickRelinquishMemory( description ); \
            DestroyMagickWand( wand );  \
            exit( -1 );  \
        }

        FILE *img_file_handle;
        MagickBooleanType status;
        MagickWand *magick_wand;
        char *img_filename;

        img_file_handle = fopen( "./leaf.jpg", "r" );
        if ( img_file_handle == (FILE *) NULL ) {
            (void) fprintf( stderr, "could not open image file" );
            exit(-1);
        }

        /* Read an image. */
        magick_wand = NewMagickWand();

        /* Problem apparently occurs here */
        status=MagickReadImageFile( magick_wand, img_file_handle );
        if ( status == MagickFalse ) {
            ThrowWandException( magick_wand );
        }

        fclose( img_file_handle );

        /* Start from the beginning... */
        MagickResetIterator( magick_wand );

        while ( MagickNextImage( magick_wand ) == MagickTrue ) {

            /* ... and check each image for a filename */
            img_filename = MagickGetImageFilename( magick_wand );

            if ( img_filename == (char *) NULL ) {
                ThrowWandException( magick_wand );
            }

            printf( "\n%s\n\n", img_filename );

            MagickRelinquishMemory( img_filename );
        }

        DestroyMagickWand( magick_wand );
        return( 0 );
    }

/******************************************************/

Hope this helps
