Yes, "lena" is a well know image benchmark. But... plplot still draws=20
it very badly... poor Lena. Try "xv lena.pgm" or "display" or=20
whatsoever. Colormap problems? A bad (my) understanding of the ppm=20
image format?

Have you noticed the comment "if" in xwin.c, FillPolygonCmd()?

 /* Fill polygons */

  if( 0 /* buggy!, try e.g. x12c. Disable it */ && pls->dev_npts =3D=3D=20

It was part of your patch (without the "0 /* buggy" part). Shall I=20
remove it, or do you intend to correct it?

Do you anticipate to need all the PLESC_IMAGEOPS operations?

I will apply your patches latter.

For the list, I quote:

even if I=20
=A0./configure --with-double --enable-tcl=3Dno =A0
I get

gcc =A0 plrender.o -L. -lplplotd =A0-o plrender \
=A0 =A0 =A0 =A0 -L -ltk -L/usr/X11R6/lib -lX11 -ltcl8.0 -ltk8.0 -lvga -ld=
l -lm
-lg2c -Wl,-rpath -Wl,/scisoft/users/mirone/tmp/PLPLOT/plplot/tmp
=2E/libplplotd.so: undefined reference to `pls_auto_path'
=2E/libplplotd.so: undefined reference to `plTclCmd'
=2E/libplplotd.so: undefined reference to `Matrix_Init'=20


where I had to add by hand -ltcl8.0 -ltk8.0 =A0otherwise compiling
complains.
Maybe it's cause of tk =A0installation on the=20
machines at work.
=A0Is'nt there a way to really cut off tcl/tk if one wants to compile
without it?

end of quote

Thanks, Joao
