Talk:Bitmap/Histogram

It would be nice to host the test PPM files at Rosetta. Anybody to help? --Dmitry-kazakov 18:41, 7 December 2008 (UTC)

Along what I have understood you need the "bureaucrat" status. Dunno who you have to ask, probably the admin. I think it would be nice to put an image for cubic and quadratic bezier curves too even if everyone know how it looks like. Blue Prawn 19:31, 7 December 2008 (UTC)

Task description

What are we supposed to do in this task? The title hints that we should write a function to create an image histogram. That would make sense. But the description talks about who knows what.

What does it mean that a data storage should "support image histograms"? That makes no sense. The data storage stores an image, I don't see how this storage could "support histograms".

I don't understand the sentence "Choosing the histogram data format take care about the data type used for the counts.". What is "histogram data format"? How choosing it could take care of some data type? Maybe the purpose of the writer was to say something like: "You must choose a data type that is capable of storing count even if all the pixels are of the same color."

If the purpose of this task is to create image histogram, why does most of the description talk about converting image into black and white art? It has very little to do with histogram. (Histogram would only be used as one possible way to automatically choose the threshold level). If such conversion is needed, it should be a separate task.
