Line

Syntax:

    Line(LineX1,LineY1, LineX2, LineY2, Optional LineColour = 1)

Explanation:

Draws a line on a GLCD from pixel LineX1, LineY1 to pixel LineX2, LineY2.

LineColour can be specified. Typically the value is 0 or 1, corresponding to GLCDBackground and GLCDForeground respectively; it defaults to 1 (foreground) if omitted.

Example:

    #include <glcd.h>

    line 0,0,127,63          ' <<< the Line instruction
    line 0,63,127,0
    line 40,0,87,63
    line 40,63,87,0

Key line: line 0,0,127,63 — draws a diagonal line from the top-left corner to the bottom-right corner of a 128x64 display. image::lineb1.PNG[graphic,align="center"]
