Drawline issue with arduino

[jubersoudagar]

Hey..
I'm struggling to get DrawLine to do what I'd expect, even when using your example code. No matter what values I put in as x0, y0, x1, y1, my line is either vertical on x=0 or horizontal on y=0.

I believe this is a problem I fixed a long time ago when I separated out each class.
I'm not sure why people keep using the combined repository, if you click on my name near the top of the page it will show you my other repositories. You will see that each class has it's own, these are the later ones with several corrections applied to them and each has a Wiki.
The problem you are having is to do with the coordinates being changed to uint32's when calculating the slope of the line and effectively using 16 bit fractions. In the RGBLEDS release I was not casting explicitly. This is corrected in this repository: https://github.com/AaronLiddiment/LEDMatrix
