First of all, just wanna thank you guys especially Chris, Branko, Marc and Dov for answering some of my questions the past 2 days. Your help is greatly appreciated. Anyway, my question regards the gimp_pencil tool. One of its parameters is an array of floats. I tried to pass in this by doing //just imagine all variables contain integers #1. @positions = (0, $startPos, $width, $startPos); gimp_pencil($layer, 4, @positions ); #2. gimp_pencil($layer, 4, (0, $startPos, $width, $startPos) ); Everytime I try to run this script, Gimp pops me a message and says: perl-arrayref required as datatype for a gimp array at blahdirectory then line number (ERROR) Anyone knows how do I fix this? Thanks all! Kenny
