First, my apologies if this is already posted somewhere, however I did a little forum searching before posting this thread and couldn't find the answer. Thanks in advance for any tips you can offer.
I'm trying to access the full resolution image data in playback mode. Basically, I want to hook into the image browser/viewer system and do some processing of images that are loaded from the external memory card and displayed on the LCD.
It seems straightforward to access the LCD image (via the viewport functions), and the raw hook functions seem to permit ready access to captured raw images, but I haven't been able to find a way to get a handle on the image data for images that are loaded from the memory card in playback mode. All I need is a pointer to a buffer, or a function that will permit me to load the image from the memory card to a memory buffer myself, etc.
