Hi all
I’m using the library provided for the Fez Touch (on Panda II). It works great.
In order to “improve” the performance when drawing a moving point, I’d like to be able to put back what was at X,Y before I use SetPixel to draw my point.
So, the question is quite simple : How to I get the color of a pixel at X,Y location ?
Question 2: FillRectangle seems to be much more efficient than DrawLine method. Am I write ? Why this ?
Question 3: What tricks could be use in order to “increase” the drawing performance ? (don’t just answer RLP please )… I’m drawing a Grid (two loop to draw, one for vertical, the other one for horizontal) and I must admit that the drawing, even if it is quite fast, is not “immediatly” done. By that, I mean that when drawing 10 lines, I can see the 10 lines appearing one by one. I know I’m not using a “3 Ghz” graphic processor, but, is there a way to display 10 lines almost at the same time, so the user won’t have the impression that the board is “kind a slow” ?
Thanks
