How to convert the preprocessed bin file to Numpy data?

[ecvgit]

I am wondering how the preprocessed bin data was converted to Numpy (28x28) data?

In the Numpy data, I see that each location has a value between 0 and 255 (not just 1). How was this value arrived at? I thought the original stroke data contained only x and y coordinates and for each such x,y coordinate, we make a 1? But this does not seem to be the case. Is there a pointer to any algorithm to convert the stroke data to the numpy array?

The bin data is basically a rendered image of the drawings. The values are 0 to 255 because that is a common way to store 8bit color data.
So if you scale the x,y coordinates to 28x28 and render and plot the lines onto an image you should get something similar.
