There is a skeleton of these files?

While I could probably look into re-implementing the AmigaOS native surface types I do have some other development related things I need to do as well that are much higher on my To Do list right now. Maybe later...

Still very low on my To Do list. I'll post when and if it changes.

Hi,

could be possibile to have the source code for the Amiga-Cairo surface?


Thank you very much.

Strange, i really have a slight, very slight feeling that my request remained unnoticed...

I've started working on an AmigaOS shared library implementation of libpixman.

The source code (based on pixman 0.34.0) which compiles already but is otherwise untested is available on github:

https://github.com/salass00/pixman_lib

Next on my to do list after first ensuring that the library works correctly is to look into enabling altivec support either in a separate build of the library or if possible as part of the same build, as I did with xvidcore.library.

Libcairo relies more on global data than libpixman so I will probably build it only as a static library to begin with (baserel support is missing from current adtools gcc versions and I don't quite understand yet how to use the small data mode to do the same).

great, thank you salass.

I compiled successfully (thanks to you info) libcairo in the past, but this lack of amiga-cairo surface. If you can provide the amiga surface code maybe some kind of hardware acceleration can be implemented.

Thank you very much

You keep requesting this.

Just to make it clear. I do not have access to the source code of the amiga-cairo, and even if I did it would not be up to me to release it.

Cairo can be used under either LGPL or MPL license (the latter does not require releasing the full source code).

Depending on how much work is required to write a surface backend for cairo (I haven't looked into this yet) I might consider writing a couple of new AmigaOS native surface backends from scratch (I'm thinking a rastport and a bitmap backend maybe).

Also it would be nice to have a native font backend for AmigaOS instead of having to use fontconfig.

Yes, please.

Would be nice to have a native backend for Amiga.

Other backend are included in cairo source, like BeOS backend. AmigaOS is not included. Perhaps Hyperion could release this part of the source?

I just tested pixman-1.library with a very simple cairo program (using cairo 1.14.2) that simply clears a surface to black and blits it in a window.

At first it didn't work correctly because the pixman constructor code wasn't being called in the pixman-1.library but I've fixed that now:

I just started working on an AmigaOS surface backend for cairo 1.14.10.

It will be rather simplistic to begin with, with more advanced h/w acceleration being added later (through CompositeTags() for instance).

Interestingly enough the cairo configure script seems to know the development state of my backend:

--- The amigaos surface backend feature is still under active development and
--- is included in this release only as a preview. It does NOT fully work yet
--- and incompatible changes may yet be made to amigaos surface backend
--- specific API.
