PIXEL%

Syntax: PIXEL% ( [#ch,] x1,y1 )
Location: PIXEL (DIY Toolkit - Vol G)

This function can be used to read the colour of a point in absolute co-ordinates on the screen with reference to the specified window channel (if any - default #1).

The main limitation on this function is that the point must appear within the specified window, so x1 and y1 cannot exceed the width or height of the specified window (in pixels), or be less than zero.

CROSS-REFERENCE:
PLOT and DRAW allow you to draw points and lines on the screen.
INK gives details about the various colour values which may be returned (this will be in the range 0...16).
