Test-OpenCLIPP produces unreadable image

[ydirey]

Hi,

after some adjustment in make (include path to CL/cl.h for compiler) and source files (adjust absolute path to cl-files) I've successfully built the Test-OpenCLIPP sub-project.
I have also loaded the well-known lena.png image for test.
After running the code the code my GPU device is recognized and success is reported:

However the produced Result.png file includes an image which nowhere near resembles the input image.
I tried manipulating the filters and parameters with no success.

I also tried to just pass the SourceData to Return.png.
The result was no better.
Do you have an idea what could cause the problems?

Thanks!

Kind regards,
Yaroslav

Modified line
lodepng_encode24_file("result.png", (unsigned char*) SourceData, ImageInfo.Width, ImageInfo.Height);
produces file "result.png" identical to the initial image.
The problem seems to come up when the image is written on the GPU device.
