* Refactor AlphaMask class to separate the mask from its source. This allows use to not just a BPicture as source for a pixel alpha mask, but also e.g. a BShape in the future (not yet implemented). * For BPicture-based masks, use the PictureBoundingBoxPlayer to determine the size of the resulting mask bitmap. The masks are now drawn into bitmaps of this size (instead of the whole view size). When alpha masks are stacked, their bounding rectangles intersect (i.e. masks further up in the stack can never be larger than masks lower in the stack). The bitmap of a mask always contains the state of itself blended with all masks in the stack below it. This also avoids frequent rerendering of the masks. They are now independent of view size. When the view origin (in screen coordinates) changes we only have to reattach the mask buffer, without having to redraw it. * The class UniformAlphaMask is used for simple masks with the same alpha value in all pixels, it uses no mask bitmap at all. Currently, it can only be used on its own and not be stacked together with other mask types.
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!
Contributing code
If you're submitting a patch to us, please make sure you're following the patch submitting guidelines.
If you're having trouble finding something in the source tree, you can use one of our OpenGrok servers:

Contributing documentation
The main piece of documentation that still needs work are the API docs (found
in the tree at docs/user). Just find an undocumented class, write
documentation for it, and submit a patch.
