Rotating an image?

[JorDy]

i would like to be able to rotate an image to certain degrees with the pad. i have came across a function which will do that but it also blits an image in the top left which cant be gotten rid of other wise the rotated image is not shown
this is the code i found:

Code: Select all

--Rotate image
function rotateImage(theImage, angle)
screen:blit(0, 0,theImage)
angle = angle*(6 + (1/3))/360
	for x = 1, theImage:width() do
		for y = 1, theImage:height() do
			tX = math.cos(angle)*(x-theImage:width() / 2) - math.sin(angle) * (y-theImage:height() / 2)
			tY = math.sin(angle)*(x-theImage:width() / 2) + math.cos(angle) * (y-theImage:height() / 2)
			screen:fillRect(tX + 480, tY + 0, 2, 2, screen:pixel(x, y))
		end
	end
end

rotateImage(MyImage, angle)
screen.flip()

try settings:
screen:blit(-100, -100,theImage)

or more till the pic is off screen.
