Re: [AGG] B2dPipe - 2D Pipeline Compiler

Awesome - I’ve used AGG for years (as well as AsmJit), and followed the news on your projects here. Very excited to see what you’ve achieved here. I’m primarily interested in using this from C++ code.

Hi Ben,

All images on https://blend2d.com site were rendered by Blend2D through B2dPipe. I have many demos, some use C++ and some node.js (through JS bindings of Blend2D). However, demos and benchmarks will be published after I release the main product - Blend2D. B2dPipe was released as a separate project to allow others to also benefit from JIT, and I posted it here because I also use analytic rasterizer similar to AGG.

I'm really looking forward to publish all the benchmarks I have as the results are really impressive, but it will have to wait a bit until Blend2D alpha is released. I compare with Cairo and Qt, and if I publish my results now there would be no way to verify the numbers are accurate.

I plan to release Blend2D at the end of February / start of March, so let's see if I can make it on schedule :)

Best,
Petr

Sounds awesome. Do you have a demo using b2dpipe to produce actual pixels, and do you have performance numbers?

Subject: [AGG] B2dPipe - 2D Pipeline Compiler

Hi list,

I would like to announce a first release of b2dpipe library. It's a 2D pipeline compiler written in C++ that I developed as a part of Blend2D project. It currently implements only 32-bit pixel formats and there are some missing features that should be finished before general use, but I think it's in a good shape for experimenting and contributing.

It's not a 2D engine and the library doesn't provide any 2D drawing context. It's a low-level library allowing you to define a 2D pipeline and to compile it at runtime by using a JIT compiler. This means that the library can be used in any rendering engine as a software-based rendering backend.

What b2dpipe offers at the moment:

  * ARGB32 (premultiplied) and XRGB32 pixel formats
  * Acceleration of various compositing and blending operators
  * Acceleration of rendering gradiends and textures
  * Acceleration of semi-transparent blits
  * 3 fill types (2 rectangle fills and one analytic)

The library doesn't provide its own rasterizer, and I don't know if it should be part of it (I guess I will put it in a separate project instead), but it has an implementation of calculating alpha coverage based on the same analytic method as used by FreeType and AGG. Base structures are defined in b2dpipe::FillData::Analytic, most importantly Analytic::Cell and Analytic::Span, which are analogous to antigrain cell and array of cells. I would provide more details to anyone who is interested about this.

Thanks for your attention, and hopes for your contribution!
