I recompiled a really simple ImageMagick app to recompress JPEGs with a
newer version of Magick++ and I've started getting this error:
ZAC-MAC:Resources zacwitte$ ./JPGCrusher ~/Desktop/chris/IMG_3001.jpg
terminate called after throwing an instance of
'Magick::ErrorMissingDelegate'
what(): ImageMagick: no decode delegate for this image format
`/Users/zacwitte/Desktop/chris/IMG_3001.jpg'
Abort trap
I'm using this on mac os x. I first installed the binary version of IM and
then compiled from source and installed with 'make install'.
Here's the simple code:
#include <iostream>
#include "Magick++.h"
using namespace std;
using namespace Magick;
int main(int argc, char** argv) {
if (argc < 2) {
cout << "Usage: JPGCrusher <imagename.jpg>" << endl;
return 1;
}
Image image;
image.read(argv[1]);
image.compressType(JPEGCompression);
image.quality(75);
image.write(argv[1]);
return 0;
}
