536 Programming
dx1, dy1 are optional and if not specified will be the top
left of trgtGRB.
c can be an color specified as #RRGGBB. If it is not
specified all pixels from rcGRB will be copied.
N O T E Using the same variable for trgtGRB and srcGRB can be
unpredictable when the source and destination overlap.
DIMGROB_P
DIMGROB Syntax: DIMGROB_P(G, w, h, [color]) or
DIMGROB_P(G, list)
DIMGROB(G, w, h, [color]) or
DIMGROB(G, list)
Sets the dimensions of GROB G to w × h. Initializes the
graphic G with color or with the graphic data provided in
list. If the graphic is initialized using graphic data, then list
is a list of integers. Each integer, as seen in base 16,
describes one color every 16 bits.
Colors are in A1R5G5B5 format (that is,1 bit for the alpha
channel, and 5 bits for R, G, and B).
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.
