It's as simple as changing the file name when you write it to the file system. Hope it's not too late. Francisco de Juan By: Johan Andersson PNG colour depths of 8 bits or less [ reply ]   2008-03-27 10:29 Hi! Love Gruff. Nice work. Though I want to show the graphs I created in gruff in a PDF. But that library only support PNG colour depths of 8 bits or less. Is it possible to save the images in this format in gruff? If not. Would it be a pain to change the source for this purpose? Thanks!
