Conversion to the standard box is done automatically. colors should be given as 3 numbers in range (0,255), or as a single RGB number. state-setting functions: gdcolor set color gdfont set pen size and style gdpen set pen size and style gdpencolor set pen color gdtextcolor set text color drawing functions (each has a matching verb ending in '01' e.g. gdarc01): gdarc draw arc gdchord draw chord gdellipse draw ellipse gdlines draw lines gdpie draw pie-shaped wedge gdpixel draw pixel gdpolygon draw polygon gdrect draw rectangle gdroundr draw rounded rectangle gdtext draw text other definitions: gdadd add wrapper gdbmp write graph to bmp file gdclip write graph to clipboard (Windows only) gddraw draw wrapper gdemf write graph to emf file (Windows only) gdopen open/clear graphics window gdselect select graphics window gdshow show graph Name Type Description gdarc verb draw arc gdarc01 verb draw arc in 0 0 1 1 gdbmp verb write graph to bmp file gdchord verb draw chord gdchord01 verb draw chord in 0 0 1 1 gdclose verb close graphics window gdcloseall verb close all graphics windows gdcolor verb set color gddraw verb wrapper for draw methods gdellipse verb draw ellipse gdellipse01 verb draw ellipse in 0 0 1 1 gdemf verb write graph to emf file gdlines verb draw lines gdlines01 verb draw lines in 0 0 1 1 gdopen verb open/clear graphics window gdpen verb set pen size and style gdpencolor verb set pen color gdpie verb draw pie-shaped wedge gdpie01 verb draw pie-shaped wedge in 0 0 1 1 gdpixel verb draw pixel gdpixel01 verb draw pixel in 0 0 1 1 gdpolygon verb draw gdpolygon01 verb draw in 0 0 1 1 gdrect verb draw rectangle gdrect01 verb draw rectangle in 0 0 1 1 gdroundr verb rounded rectangle gdroundr01 verb rounded rectangle in 0 0 1 1 gdselect verb select graphics window gdshow verb show graphics Also: points are plotted to pixels in a box with coordinates (0,0) at top left points should be given as a 2 element vector or 2 column matrix colors should be given as 3 numbers in range (0,255) for RGB, or as a single RGB number.
