Modify OpenGL / OpenCL / GnuRadio / FFT / C++ Code, Generate images from data

I have a program called fosphor which essentially displays the FFT histogram from a complex IQ radio signal.

You can find the software here [login to view URL]

The histogram in the UI is limited to 1024 samples though, so I want to create a version that allows me to save the histogram continously into a binary file that can be read later, to retrieve the data in a random access manner.

I assume to solve my issue, less than 100 lines of code have to be added/changed only.

I have already inspected the code and understand most of it, though I was unable to deal with the background/transparceny/colormap or such correctly when exporting the data myself. I basically got the data but the colormap does not match, so the image appears very off.

To finish this project, you have to pixel-accurately recreate or export the image data from the UI into a file which can later be read again. A continous file is preferred but non-overlapping losless images like .png will do the job as well. It is not required for this project, but in the end, the code shall run headless, so without UI. For this reason, the solution must not use screenshot utilities or alike but export the data from within the code.

You also need to be able to explain me briefly (5-10min), how the transparency has to be handled, in order for the image to have identical pixel values in comparison to the original program. I guess as soon as it has been implemented, this should be a matter of seconds.

I am confident, I have the skill to solve my problem myself, eventually, though I'd rather have someone do the task for me or help me. I assume basic skills in OpenCL/OpenGL/C++ are helpful, if not even required.

I want to be able to communicate with you easily, so I test whether you have read this description or just copy-pasted your default resume like an senseless opener: In case you have read till here, start your bid with "IR EAD IT" followed by 2 plus 8 in the first line.

Also, start with a small bid and we can have a chat/audio talk and agree on a larger budget and realistic milestones after that.

In case you want a sample, there is a file attached called `[login to view URL]`.

You have to install gnuradio 3.9, opencl, build utilities, git, gr-fosphor ... and then you can open `[login to view URL]` and run it. This is your starting point. If you need any help to get the install running, let me know, as I had trouble myself doing so.

PS. If you are able to recreate the image pixel-perfect in another language like python, js, ..., just let me know in your bid. This would qualify as a solution as well and might earn you extra points.
