I need opinions on how to output histograms. A histogram can be saved as image or text.
We can save as text in simple format like: 2 50 ... 3 14 Should I use ofstream? Chris suggested we could just print to standard output and then you could do: our_operation > file.txt About saving the histogram as image, should there be one single function to both calculate and draw the histogram to ImageBuf. If I understood correctly then, Chris suggested we could have one function to compute histograms and save the data in an ImageBuf, not the picture of the histogram but the data. That way we can place histograms on stack for input to other operations. Then there would be a separate function to take that and draw a histogram, and save it as image. Also the text output function can be separate from the histogram computation function. It would take a computed histogram from stack and save it as text file. Chris sorry if I misinterpreted something you said ;) I am just starting a conversation on this. Stefan
