Announcing a re spawned rcairo

[Øyvind Kolås]

Announcing a re spawned rcairo
=============================

rcairo[1] is a cairo[2] extension for ruby.

Cairo is a resolution and device independent vector graphics drawing
library, which provides a postscript like drawing model. The release
contains some simple tests, and some not so simple tests utilizing
cairo through ruby (samples/canvas contains a small windowing system.

Features
========

- PNG writing
- interactive applications using gtk+ and hardware acceleration.

Download
========

The extension is available as a tarball[3] or from cairo CVS[4] see
the cairo cvs instructions[5] for information on how to get rcairo and
some of its dependencies from cvs. See the README[6] for spartan build
instructions, rcairo uses setup.rb and is hopefully easy to wrap up
for gems and RPA.

To be done
==========

- Review API/conventions.
- patterns (for gradients, and repeating images).
- binding of cairo-svg for svg rendering support.
- integration with sdl extension, for easy platform independent
(albeit not hardware accelerated) use.
- PDF writing.
- integration with pango extension, for unicode based text layout capabilities.
- integration with the native support in gtk+
- integration with other toolkits?
- documentation

Feedback and patches are appreciated, especially regarding how cairo
code should be used from ruby. Most of the fancy things can be added
as syntactic sugar, but I am uncertain how to handle for instance
enumerated values in a good way.

Attachments: a png file, and the ruby script used to generate it, just
to give a taste of the API, more samples exist in the release. Mail
with attachments bounced from list, placing the sample at [3] for now.

Happy drawing.

Hello Øyvind,

I'm shure it is a nice project, but my in-head spam deletion algorithm nearly send my finger to the delete button, because the header line seemed to contain so much noise. "a re spawned rcairo" seemed a bit like "a re you hav1ng your dose of v1agra" to me

I'm happy to have stopped myself in time, because I think I could need this later.

best regards,

Brian

Packaged up in PLD's CVS tree. Delightfully easy to make an RPM of. Good
clean work!
