Pixels and Cartesian

ARC_P

ARC Syntax; ARC(G, x, y, r [ , a1, a2, c])

ARC_P(G, x, y, r [ , a1, a2, c])

Draws an arc or circle on G, centered on point x,y, with radius r and color c starting at angle a1 and ending on angle a2.

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

r is given in pixels.

c is optional and if not specified black is used. It should be specified in this way: #RRGGBB (in the same way as a color is specified in HTML).

a1 and a2 follow the current angle mode and are optional. The default is a full circle.

Example:

ARC(0,0,60,0,π,RGB(255,0,0)) draws a red semicircle with center at (0,0)—using the current Plot Setup window—and with a radius of 60 pixels. The semicircle is drawn counterclockwise from 0 to π.

BLIT_P

BLIT Syntax: BLIT([trgtGRB, dx1, dy1, dx2, dy2], srcGRB [ ,sx1, sy1, sx2, sy2, c]) BLIT_P ([trgtGRB, dx1, dy1, dx2, dy2], srcGRB [ ,sx1, sy1, sx2, sy2, c])

Copies the region of srcGRB between point sx1, sy1 and sx2, sy2 into the region of trgtGRB between points dx1, dy1 and dx2, dy2. Do not copy pixels from srcGRB that are color c.

trgtGRB can be any of the graphics variables and is optional. The default is G0.

srcGRB can be any of the graphics variables.

dx2, dy2 are optional and if not specified will be calculated so that the destination area is the same size as the source area.
