- <h1>Description</h1>
- <table>
- <tr>
- <td>
- 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.
<br />
-
<br />
- 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.
