Progressive JPEG
Posted: 2013-08-19T11:25:09-07:00
Hello,
I have a progressive/interlaced JPEG that I cut at half the file in order to play with partial images. So, with I don't have any problem, I can see the pixelated JPEG. However, when I try to open it with Magick++ I get a WarningCorruptImage (normal, I can see in the terminal that display catch the same).
Then, I try to get the partially rendered image with in my C++ code, but there pixels is a null pointer. So, how can I do like the display utility and get the pixels of the "blurry" image ?

Magick::PixelPacket *pixels = image.getPixels(0, 0, width, height);
