Thanks for the reply!
Interesting. We have a Mac G4 here, but I never thought to test out the bug on the Mac - silly me. I assume that PalmRez (part of Codewarrior) is a Palm-produced product, not a Metrowerks-produced product? It's not so much that I need PackBits to work (I really don't need a working .PRC), but rather, we want to let our customers know that this problem they're seeing is NOT directly caused by any of our software. And since it works on the Mac, we can provide them with a work-around (buy a Mac). :) Thanks for forwarding the information to the correct Palm development team. I hope, at some point in the future, the bug can be fixed, but I won't hold my breath. :) Thanks again for looking into this, Doug. -----Original Message----- From: Regis Nicolas [mailto:[EMAIL PROTECTED]] Sent: Friday January 25, 2002 07:51 To: Palm Developer Forum Subject: RE: Demo and Source Code of PackBits Compression Bug - Comments R eque sted Doug, Too late, you indirectly contacted Palm :-) I had a quick look at your problem. The bitmap inside the PRC is corrupted. I think it's because of a bug in PalmRez for PC. We generated the prc using your files and project on a MAC and it works fine. I can send you the Mac generated prc if you like. I will forward your problem to the appropriate team at Palm but I cannot give you any guarantee of when it will be fixed, if it is at all. Cordially, Regis. ------------------------------------------------------------------ Regis NICOLAS - Manager, Communication Software Palm OS 5.0 Technical Lead When the finger points to the sky, the idiot looks at the finger. -----Original Message----- From: Doug McFadyen [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 24, 2002 3:15 AM To: Palm Developer Forum Subject: Demo and Source Code of PackBits Compression Bug - Comments Reque sted I've created a Palm OS 4.0 application, complete with source code and a CodeWarrior for Palm R7.x project file, that demonstrates a bug with Palm's handling of PackBits compression for 16-bpp color bitmaps. You can download the source code and CW project files here: http://www.user.dccnet.com/dougmc/packbug.zip This project requires Palm OS 4.0 SDK, and you'll have to run it on a device capable of doing 16-bpp color (like the Palm m505, or equivalent Palm OS Emulator ROM). To use, run the app, and it should show a bitmap in 16-bpp color mode. This is using the a non-compressed bitmap. Select the checkbox to Use PackBits, and the colors should go all nuts. The PackBits bug ONLY seems to be present for 16-bpp color bitmaps, as all other color depths appear to work fine. Any and all comments are welcomed. Can anyone see ANYTHING that I'm doing wrong which would cause this? I'd like to make sure it's really a Palm OS bug before I attempt to contact Palm about it.
