Hi all,
I've just tried to add some debug statements to one of the MagickWand
example programs (see below). When I invoke that program on some very
large TIF (~300 MB) or PNG file, the memory consumption shortly
increases, but after destroying the MagickWand and calling
MagickWandTerminus(), all memory is freed.
Here's the code:
--8<---------------cut here---------------start------------->8---
#include <stdio.h>
#include <stdlib.h>
#include <wand/MagickWand.h>
int main(int argc,char **argv)
{
MagickBooleanType status;
MagickWand *magick_wand;
if (argc != 3)
{
(void) fprintf(stdout,"Usage: %s image thumbnail\n",argv[0]);
exit(0);
}
MagickWandGenesis();
magick_wand=NewMagickWand();
fprintf(stdout,"Created magick wand.\n");
status=MagickReadImage(magick_wand,argv[1]);
MagickResetIterator(magick_wand);
while (MagickNextImage(magick_wand) != MagickFalse)
MagickResizeImage(magick_wand,106,80,LanczosFilter,1.0);
status=MagickWriteImages(magick_wand,argv[2],MagickTrue);
magick_wand=DestroyMagickWand(magick_wand);
MagickWandTerminus();
fprintf(stdout,"Terminated magick wand & sleeping 20 secs.\n");
sleep (20);
fprintf(stdout,"Bye.\n");
return(0);
}
--8<---------------cut here---------------end--------------->8---
Currently, I cannot see where's the difference between that code and the
one in image.c...
Bye,
Tassilo
