Various things of the DNG SDK return a dng_image. The stage1, stage2 and stage3 are an RGB image. And if you use dng_render, you also get a dng_image.
I'd like to get a buffer of pixels (with for example R, G, B values). However, I haven't found any way in the API to get such a buffer.
For example, dng_image has member functions to get its width and height, but nothing to get the pixel buffer or even the value of a single pixel.
And I experimented a bit with the "Get" method of dng_image, but if I don't put anything in fArea of the buffer parameter, I didn't manage to get anything interesting, while if define a rectangle there, the whole program corrupts and crashes a bit after using dng_image.Get.
So, basically, my question is: how can I get the pixel buffer from a dng_image?
This is for displaying it on a computer monitor BTW.
Unfortunately the dng_validate sample doesn't help me out, because they don't get any pixel values there, they just call an API method to convert the dng_image to a TIFF file, which doesn't help me at all because I need RGB pixels on a screen, not a TIFF file on a disk.
Thanks.
