Saving/loading depth stream frames

Hey.

So I plan to process depth frames using OpenCV offline. I want to save a particular depth stream frame as an image openCV can interpret. This is later to be processed in OpenCV and converted into a PXCImage again for constructing point clouds.

I have functions to convert my PXCImage to CV_16U image mats (and back again). The conversion back to PXCImage works if I do it on the fly so I know these work. Also the saved image looks similar to my depth stream. However, if I first save to disk then try and load that image later on I get weird results.

I am saving my image in PGM format (said to be uncompressed) using

cv::imwrite("output.pgm", outputMat);

I load my image back using

cv::imread("output.pgm", -1);

But when I convert back to PXCImage and try to show, I just get a bunch of diagonal lines. Is the type somehow getting messed up here?

Any help much appreciated!

Sorry I was able to get

Sorry I was able to get things to work. I use imread with the flag CV_LOAD_IMAGE_ANYDEPTH. Things are all good :).
