Description

This sets a background image for output window. The text in the output window is drawn on top of this. If the image does not completely fill the window, the background colour is visible beneath it.

FileName - the disk file to load the image from. It should be a BMP or PNG file, not a GIF, TIF or other file type. The file name can be the empty string (ie. "") in which case any existing image will be removed.

Mode - a number indicating where you want the image positioned on the screen. Whenever the screen is resized or redrawn the contents of the image are drawn in the requested position:

0 = strech to output view size
1 = stretch with aspect ratio
2 = strech to owner size
3 = stretch with aspect ratio
4 = top left
5 = center left-right at top
6 = top right
7 = on right, center top-bottom
8 = on right, at bottom
9 = center left-right at bottom
10 = on left, at bottom
11 = on left, center top-bottom
12 = centre all
13 = tile

The "stretch" versions expand or contract the image to fit the output window. If you use "with aspect ratio" the image fits exactly top-to-bottom, and may be clipped left-right to preserve the original aspect ratio.

The difference beteween "output view" and "owner size" is that with "output view" (modes 0 and 1) the image will tend to flicker annoyingly if you have automatic resizing of the command window active (as this will make the output window size change, and thus the image size will keep changing) .

Lua example

SetBackgroundImage ("wolf.bmp", 0)
