Draw line 1 pixel width

[albertofll]

Hello I begin to playing with this library to check the possibility of using it for a drawing and text editor. The come from GDI and drawing a line with this code:

`img.AntiAliased:= false;

path2[0].X:= 50;
path2[0].Y:= 150;

path2[1].X:= 400;
path2[1].Y:= 150;

DrawLine(img, path2, 1, Color32(clBlack), esPolygon);`

I get a two pixels width. Other line with this code : DrawLine(img, path2, 4, Color32(clBlack), esPolygon); draws the line with 4 pixels. I try to set img.AntiAliased:= false , but it seems doesn't affect to this. How can I draw that line with one pixel width?

Thanks for the feedback.

What's currently happening is that the renderer is drawing a line at Y = 149.5, so it's splitting the line between Y = 149 and Y = 150.
Of course this isn't a good long term solution, but for the moment you'll need to offset your lines by 0.5 both horizontally and vertically to get the 1px width full density lines you're expecting.

Why is this offset there? Because when antialiasing is enabled, mixing perfectly solid 1px horizontal and vertical lines with other antialiased lines looks odd. But when antialias is disabled, I can see that this 0.5px offset is unhelpful and should be fixed.
