Message-ID: <1990Apr9.085729.16740@nada.kth.se> Date: 9 Apr 90 08:57:29 GMT Sender: news@nada.kth.se (News) Reply-To: d88-jwa@nada.kth.se (Jon W{tte) Organization: Royal Institute of Technology, Stockholm, Sweden Lines: 16 I have a collection of bitmap PICTs that I have obtained by capturing a part of a window. The problem is; some of these are automagically grayscaled when reduced, and some are just shrunk old-style, keeping all the black bits. What Criterium is there for DrawPicture (or CopyBits) to gray-scale one of these pictures ? IM V isn't talking, and trial-and-error made me so frustrated I wrote my own BW2gray filtering program (a simple 3x3 filter - not fast, but it works) Thanx in advance, h+ --- Stay alert ! - Trust no one ! - Keep your laser handy ! --- h+@nada.kth.se == h+@proxxi.se == Jon Watte longer .sig available on request
