PIXON_P

PIXON Syntax: PIXON([G], x, y [ ,color])

PIXON_P([G], x, y [ ,color])

Sets the color of the pixel G with coordinates x,y to color. G can be any of the graphics variables and is optional. The default is G0, the current graphic. Color can be any color specified as #RRGGBB. The default is black.

RECT_P

RECT Syntax: RECT([G, x1, y1, x2, y2, edgecolor, fillcolor]) RECT_P([G, x1, y1, x2, y2, edgecolor, fillcolor])

Draws a rectangle on G between points x1,y1 and x2,y2 using edgecolor for the perimeter and fillcolor for the inside.

G can be any of the graphics variables and is optional. The default is G0, the current graphic.

x1, y1 are optional. The default values represent the top left of the graphic.

x2, y2 are optional. The default values represent the bottom right of the graphic.

edgecolor and fillcolor can be any color specified as #RRGGBB. Both are optional, and fillcolor defaults to edgecolor if not specified.

To erase a GROB, execute RECT(G). To clear the screen execute RECT().

When optional arguments are provided in a command with multiple optional parameters (like RECT), the arguments provided correspond to the leftmost parameters first. For example, in the program below, the arguments 40 and 90 in the RECT_P command correspond to x1 and y1. The argument #000000 corresponds to edgecolor, since there is only the one additional argument. If there had been two additional arguments, they would have referred to x2 and y2 rather than edgecolor and fillcolor. The program produces a rectangle with a black edge and black fill.
