Hello all
I was wondering how it's possible to find out if an image in the iPhone photo library is isotropic or anisotropic. Basically how many millimeters each pixel measures in height and in width.
In JPG images the information is hardcoded into the data stream so it's possible to do by simply pointing a const char* to the image file, but I'm not sure I can do that with the data the iPhone image returns.
Thank you in advance
