filled triangle

[Fred Buffington]

great!

I can modify that for a triangle pointing to the right instead of down (changing
your count to 3) very easily. thanks

Fred,
Just set MyPolygon.count= 3 for a triangle

Im using the graphics and xprint statements.

This is how ive done it so far.

printed a GRAPHIC/XPRINT BOX (filled) with black
then set line width to 1
used graphic/xprint line to print white lines from the top left to center right
and bottom left to center right to 'bleach out' the unwanted black of the
box.

I'll look at your suggestions thanks.

GDI: Polygon function

PB: GRAPHIC POLYGON function

Are you drawing directly to a DC, that is not using PB GRAPHICS functions or?

I'm wanting to print on an attached graphic (not a loaded bmp) a filled triangle
i.e. like > but filled in.

I've tried using MS Linedraw and Generic DOS and use chr$(16) which would
be what i want but that doesnt work. Anyone found a way ?
