OpenCV [[OpenCV]] revisions tested: 2.3.1 and r7035
Operating System: Win 7 32bit
Compliation Environment: mingw32
mingw32 versions tested: 4.4.1, 4.5.2, 4.6.1
Work days spent: 2 :/
the all mighty imread function of highGUI module will not load JPEG images if PNG support is not compiled into OpenCV. [[OpenCV]]. After trying to compile a stripped openCV for my project I was left unable to load JPEG images (the only format i'm interested in actually). With painstalking efforts I have made a table of 18 compile-time parameters and tested sensible combinations to narrow down the problem down to one parameter, PNG support. I recompiled OpenCV [[OpenCV]] countless times in order to be sure.. The above versions of OpenCV [[OpenCV]] and mingw32 are guaranteed to be affected.
While not being a showstopper, it's really a BIG loss of time... It would be great if it's verified by third parties and get documented in the wiki so other innocent people don't pull out their hair as i did.
Still appriciate the collosal efforts put into this, you rock!
keep up good work:)
