Yes, in the case of the rectangle drawing I think it was a typo by who implemented the current rectangle in fcl-image, I have done various similar typos in my coding and they don't mean I really wanted to redefine rectangle. But the TCanvas line is trully confusing by not adding the last pixel. -- Felipe Monteiro de Carvalho _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
