xrects
draw or fill a set of rectangles
Calling Sequence
Arguments
rects
matrix of size (4,n).
fill
vector of size n.
Description
xrects draws or fills a set of rectangles. Each column of rects describes a rectangle (upper-left point, width, height) in user coordinates:rects=[x1 y1 w1 h1;x2 y2 w2 h2;...]'.
fill(i) gives the pattern to use for filling or drawing rectangle i:
if fill(i)<0, rectangle i is drawn using the line style (or color) -fill(i)
if fill(i)>0, rectangle i is filled using the pattern (or color) fill(i)
if fill(i)=0, rectangle i is drawn using the current line style (or color).
WARNING: please note that height is positive downwards.
