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).

This function will work in MODE 4, 8 and 12 (on the THOR XVI, if you have v0.9+). 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.

NOTE

Although PIXEL% will work wherever the screen base is located, prior to v1.0, it assumed that a line of pixels takes 128 bytes - early versions will not therefore work on higher resolutions.

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).
