Methods

<void>reload()

Reloads the bitmap file using the same name and path. You don't need to use the file browser to reload the bitmap after you've updated it in your paint program.

Clicking reload for any instance of the map updates the map in all sample slots and in the scene.

<void>viewImage()

Displays a Virtual Frame Buffer that shows the bitmap surrounded by a region outline. The region outline has handles at its sides and corners. When cropping is on, dragging the handles changes the size of the crop area. You can also drag within the region area to move it.

The VFB editing window has U/V and W/H (width/height) spinners on its toolbar. Use these to adjust the location and size the image or crop area.

When Place is turned on, dragging the region area handles changes the scale of the bitmap (hold down CTRL to preserve the bitmap's aspect ratio), and dragging the image changes its location within the tile area.

When Crop is turned on, the UV or XY button at the right of the virtual frame buffer toolbar lets you switch between using UV or XY coordinates in the toolbar spinners. Also, you can zoom out by pressing SHIFT+Z and zoom in by pressing Z.
