Description

This creates a small image (bitmap) by specifying the bit pattern for an 8 x 8 bit image. This is primarily intended for making patterns for use with WindowImageOp, described elsewhere. By designing suitable patterns you could make grass, waves, or other landscape effects for use in maps.

WindowName - the name of an existing miniwindow.

ImageId - the image id to store this image under.

Row1, Row2, Row3, Row4, Row5, Row6, Row7, Row8 - the bit pattern for each row

The easiest way of making your own pattern is to use Lua's tonumber function and work in binary. When doing that, each '1' represents a bit that is set (and is thus in the PenColour) and each '0' represents a bit that is clear (and is thus in the BrushColour).
