Magick++ strip exif

[michmix]

I want to remove EXIF from JPEG (or another) image in my c++ program (like convert -strip in command line).
For test version I use BMP buffer image, then save as JPEG again. And I have not found another way

Hi!

I'd be interested in that as well, did you manage that?

(i tried using MagickCore::ThumbnailImage but it looks as though i can not manage the proper convert between Magick::Image and MagickCore::Image:

Code: Select all

int main(int argc,char **argv)
{
  MagickCore::ExceptionInfo
    exception;

  MagickCore::Image
    *image,
    *images,
    *resize_image,
    *thumbnails;

  MagickCore::ImageInfo
    *image_info;
thumbnails=MagickCore::NewImageList();

  Magick::Image image_m;
  try{image_m.read(argv[1]);}catch(...) {return 1;}
  images=image_m.image();

  while ((image=ShiftImageList(&images)) != (MagickCore::Image *) NULL)
  {
     resize_image=MagickCore::ThumbnailImage(image,150,150,&exception); // EXECUTION ERROR HERE: magick/resize.c:3271: main: Assertion `exception->signature == 0xabacadabUL' failed.
    if (resize_image == (MagickCore::Image *) NULL)
       MagickCore::MagickError(exception.severity,exception.reason,exception.description);
    (void) MagickCore::PushImageList(&thumbnails,resize_image,&exception);
    MagickCore::DestroyImage(image);
    MagickCore::DestroyImage(resize_image);
  }

  (void) strcpy(thumbnails->filename,"image.png");
  MagickCore::WriteImage(image_info,thumbnails);
  MagickCore::DestroyImageList(thumbnails);
  MagickCore::DestroyImageInfo(image_info);
  MagickCore::DestroyExceptionInfo(&exception);
  MagickCore::DestroyMagick();
  return(0);
}

)

Thx!

Mika.

Answering myself:

Code: Select all

MagickCore::StripImage(image_.image());

does that very well. Although it strips all profiles, to strip specifically exif profiles, the profile function should be prefered.
