Static methods
staticbresenham (x1:Int, y1:Int, x2:Int, y2:Int):Array<Point>
Bresenham's line algorithm, returns the points on the line x1,y1 to x2,y2
Parameters:
x1 | x-coordinate of the first point. |
|---|---|
y1 | y-coordinate of the first point. |
x2 | x-coordinate of the second point. |
y2 | y-coordinate of the second point. |
Returns:
The points on the line x1,y1 to x2,y2
staticcopyLines (destination:Bitmap, source:Bitmap, lines:Array<Scanline>):Void
Copies source pixels to a destination defined by a set of scanlines.
Parameters:
destination | The destination bitmap to copy the lines to. |
|---|---|
source | The source bitmap to copy the lines from. |
lines | The scanlines that comprise the source to destination copying mask. |
staticdrawLines (image:Bitmap, c:Rgba, lines:Array<Scanline>):Void
Draws scanlines onto an image.
Parameters:
image | The image to be drawn to. |
|---|---|
color | The color of the scanlines. |
lines | The scanlines to draw. |
staticscanlinesForPolygon (points:Array<Point>):Array<Scanline>

Parameters:
points | The vertices of the polygon. |
|---|
Returns:
Scanlines for the polygon.
