Hi All,
I tried very simple code to read an image from url but failed.
My code is
Image image("
http://www.imagemagick.org/discourse-server/styles/subsilver2/imageset/site_logo.png
");
cout << image.columns() << " " << image.rows() << endl;
image.scale("20%");
image.write("1.jpg");
I find that the image column and row are all 0
therefore the write() will have a memory allocation exception.
Beside, if I use the convert executable, it works reading an image with url
So I don't know why my code cannot work...
I hope someone can tell me how to fix this problem.
Thanks
Shane
