libprint had a very conservative size limitation (4MB) for the bitmap it allocates. This leads to splitting a page to print in several "bands" (about 5 in my testing). However, these may still be too large for the printer driver to handle, which means the driver may be further slicing things up, or other drivers may need the full page anyway and recompose it in some way. Instead of an hardcoded limit, now try to allocate a bitmap for the whole page, and if that doesn't work, progressively increase the number of bands until we manage to allocate a bitmap. Stop when we have split the page in 256 bands, as it seems rather pointless to be that far. Call debugger when this happens, as there doesn't seem to be a way to do better error handling here (the code used to raise std::bad_alloc if BBitmap allocation failed, or just return an invalid bitmap and view).

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
