Auto Size |
||
|
Auto Size automatically shapes the frame to an exact multiple of the
texture tile size. Tile size may be either the texture width or
height depending on the state of Max Tiling.
But Auto Size only works when the image is significantly larger than the
texture. So the plugin automatically disables the Auto Size check box
when it decides that it can't do auto sizing properly. The rule for
enabling Auto Size is that the image width and height must be at least
3 times the tile size.
In most cases the original image dimensions will not be a multiple of the tile size. So Auto Size reduces the frame size to fit within the image boundaries. A side effect of this is that there will usually be an area around the perimeter of the image excluded from the frame. The Fill control gives you a choice of either leaving the excluded area unmodified or filling with a single solid color that you can select. One alternative to remove the outer perimiter fill area is to manually resize the image canvas to a multiple of the tile size. That's what the Size Info boxes are for. They show the next larger size the image should be to fit an exact number of tiles into a frame that extends to the image boundaries. Another alternative is to apply the auto sized frame to the image and then crop the image to fit the frame. The Fill control is intended to help with image cropping by allowing you to fill the outer perimeter area with a single solid color, making it easy to select the area with the graphics editor's magic wand tool. Once the area is selected, invert the selection and then crop the image. One more thing to note is that because the frame size is always restricted to a multiple of the tile size, the Frame Width control may seem to work strangely. What happens is that as you increase the Frame Width, no frame is painted until it reaches at least 1 tile size. Then the frame suddenly appears all at once. As you increase the Frame Width more, this repeats until it reaches 2 times the tile size, etc., with the frame suddenly changing width by a multiple of the tile size as you cross each tile size boundary. This is the way the plugin is designed to work when Auto Size is selected. The following example shows the same frame applied to an image without Auto Size selected and with Auto Size selected. In this case the image dimensions are not a multiple of the tile size, so the frame is smaller than the image.
