Remarks
By default (ImageFileScale = 0), an image file is automatically scaled to ImageSize. Set ImageFileScale to specify a scale. For example, if ImageFileScale is set to 1, then the image from the file is scaled by a factor of 1 (no change). If ImageFileScale is set to 2, then the image is twice as large, and so on. The image is scaled from the top left corner and portions of the image that are outside of ImageSize are cropped. If the scaled image is smaller than ImageSize, then the remaining portions of the grab image are filled with black.
