FILLPOLY_P
FILLPOLY Syntax: FILLPOLY_P([G],{(x
1
, y
1
), (x
2
, y
2
),…(x
n
, y
n
)},
Color, [Alpha])
FILLPOLY([G],{(x
1
, y
1
), (x
2
, y
2
),…(x
n
, y
n
)},
Color, [Alpha])
For the polygon defined by the list of points, fills the
polygon with the color defined by the RGB number Color.
If Alpha is provided as an integer between 0 and 255
inclusive, the polygon is drawn with the corresponding
transparency level. You can use a vector of points instead
of a list; in this case, the points can be expressed as
complex numbers.
Example:
FILLPOLY_P({(20,20), (100, 20), (100,
100), (20, 100)}, #FF, 128) draws a square, 80
pixels on a side, near the upper left of the display, using
the color purple and transparency level 128.
GETPIX_P
GETPIX Syntax: GETPIX([G], x, y)
GETPIX_P([G], x, y)
Returns the color of the pixel G with coordinates x,y.
G can be any of the graphics variables and is optional.
The default is G0, the current graphic.
GROBH_P
GROBH Syntax: GROBH(G)
GROBH_P(G)
Returns the height of G.
G can be any of the graphics variables and is optional.
The default is G0.
