I have a JPG image that is 3264 x 2448 (2.34 MB) and MagickReadImage() won't load it. It complains:
Code: Select all
test3.c main 22 Empty input file `input.jpg' @ error/jpeg.c/JPEGErrorHandler/318If I resize it to 800 x 600 with mogrify, it will load.
Here's a simple test program and output illustrating the problem:

pgg@g550 ~/test
$ ls -l

int main() {

MagickWandGenesis();
mw1 = NewMagickWand();
if( !MagickReadImage( mw1, "input.jpg" ) )
ThrowWandException( mw1 );
MagickWriteImage( mw1, "output.jpg" );
mw1 = DestroyMagickWand(mw1);
MagickWandTerminus();
return 0;
