Hi All
I've come accross Irfranview's Lossless Rotation feature and have rotated a few photos with it to great delight as the file size was close to the original unlike in Windows XP Picture Viewer were it would lose 0.1mb or something.
Anywho I also have some other photos taken by my previous 4 megapixel Canon IXUS 430 camera. These 4 megapixel photos have the dimension of 2272x1074. Now 2272 is divisible by 16 but 1074 is not. Well it is divisible by 16 but it results in 106.5 so its not a full integer.
Anywho i rotated a file with the Lossless Rotation Plugin and it worked automatically. No prompt came up nor was the resulting image cropped by 8 pixels to get within a multiple of 16.
So i'm wondering, was that a loseless rotation (Since it is a multiple of 8 although not 16). Or did it rotate with some loss although a prompt didn't come up???
Additonally could someone tell me what the Optimize JPEG option is for? If u want to do a loseless rotation why would you optimize the JPEG?
Thanks for your help! Much appreciated!
Cheers
