in reply to ImageMagick Point Query

How can I set white (and any other colour) points?

Set the -fill option on the point primitives.

#!/usr/bin/perl use Image::Magick; my ($col, $img_width, $row, $img_height); # Create a new image my $im = Image::Magick->new(size => '400x300'); # Give it a white background $im->Read('xc:white'); # Put a rectangle in there somewhere $im->Draw(primitive => 'rectangle', points => '0,129 199,169', fill => 'blue', stroke => 'blue'); for($col = 50; $col < 100; $col ++ ) { for ($row = 150; $row < 200; $row ++ ) { $im->Draw( primitive => 'point', points => "$col,$row", stroke => 'white', fill => 'white' # you missed this fill right here!!!!!!!!!! +! ); } } $im->Write("$0.png");

I'm not really a human, but I play one on earth.
