Scaling the TileImage command

BlitzMax Forums/BlitzMax Beginners Area/Scaling the TileImage command

I have an image I am tiling using TileImage and I want to scale it, how can I do this? Apparently SetScale doesn't affect TileImage!

looking at the source of the TileImage command, it has this:

	blitz2d_driver.SetTransform 1,0,0,1

so it's overriding any transform settings you are using.

You would probably have to rewrite the function to take into account scale.

I know this is an old thread, but I just added a function to the Code Archives to include the current scale and rotation.

Hi
Maybe this function could help you.

Function TileImage2(Image:TImage, X:Float=0, Y:Float=0, SX:Float=1.0, SY:Float=1.0, Frame:Int=0)
	Local TempWidth, TempHeight
	TempWidth = Image.Width
	TempHeight = Image.Height
	
	Image.Width:*SX
	Image.Height:*SY
	
	TileImage(Image, X, Y, Frame)
	
	Image.Width = TempWidth
	Image.Height = TempHeight
End Function

SX and SY for scale.

Ups, didn't see the age of the thread ;)
