image = file handle variable to a previously loaded image xscale# = the amount to scale the image horizontally yscale# = the amount to scale the image vertically |

Use this command to rescale an image to a new size using a floating point percentage (1.0 = 100%, 2.0 = 200%, etc). Using a negative value perform image flipping. You must've previously loaded the image with LoadImage or LoadAnimImage. This is NOT intended for REAL TIME scaling of images! Precalculate your images before running your program, or you will likely see massively slow renderings of graphics. |
