Hi all,

Is plplot a real equivalent to matlab? of course not, it is better!
But, well, am I in front of an issue that may change my mind?
NO, it's impossible!! so please, help me!

Fast:
Is there a plplot equivalent to the matlab function FILL?:
FILL Filled 2-D polygons.
FILL(X,Y,C) fills the 2-D polygon defined by vectors X and Y
with the color specified by C.  The vertices of the polygon
are specified by pairs of components of X and Y.  If necessary,
the polygon is closed by connecting the last vertex to the first.

Detailled:
I'm using PDL plplot interface and i would like to plot an image pixel by pixel
(the pixels of this image are rectangular and have different sizes).
I've read plplot doc, have a look to x15.pl and x16.pl examples but, well, :-(
I have not understood anaything.
Anyway, I've found a VERY INEFFICIENT way to do it:
\$z is my image, (Xpos* and Ypos*) are the limits of each pixels

for (\$k=0;\$k<\$Nbpix;\$k++)
{
\$w = ones(2,2)*\$z(\$k);
\$XposLeft(\$k),
\$XposRight(\$k),
\$YposBot(\$k),
\$YposUp(\$k),
\$shedge, \$fill_width,
\$cont_color, \$cont_width, 1, 0, 0, 0);
}
Anyway, since \$Nbpix is 512*100, the display takes a long time....
Perhaps there is a way with \&pltr(1or2) and \$cgrid(1or2) as in the examples
but i did not understand the impact on the surface....

thanks all,

best regards,

bruno
