Hi Ken, good improvements to Alien! Are you are using Installer to load Alien? Would be better to put the Alien>>#initialize into a post Install method, does Installer have that? The AlienLoader does that, so your fixes should work. What stuff is in Alien and not in "Alien Lite"? Fernando Il giorno Sep 26, 2009, alle ore 1:59 AM, Ken Treis ha scritto:

For anyone who's been playing with this, I just posted another new revision of Alien that fixes the platform sizes to match C platform sizes. Not sure what I was thinking in the first go-around. Anyhow, if you load Alien-Core-kdt.58 in Pharo, you'll need to re-initialize Alien:
Alien initialize
In other news, I've got CairoGraphics mostly working in GemStone (2.3.1) now too, running on top of an "Alien Lite" that provides support for the types of function calls I need to make. If anyone is interested in this, email me directly and I'll send you the code once I've worked out the remaining major bugs.

Hi Damien,
Yes it definitely works -- at least for me, on Mac OS X. Recent VMs from John McIntosh have the plugin already, though on the mac it only searches for libraries in a few select places and it doesn't accept absolute paths. Hopefully this will be resolved soon; for now I've symlinked the library into my Squeak VM's plugins folder.
On Linux you may have to compile a VM yourself to get the plugin; I know it's in the VM source tree.
For a quick demo, try:
|image cr backgroundGradient textGradient| image := CRImageSurface format: CRFormat argb32 extent: 300@200. cr := image context. backgroundGradient := CRLinearGradient from: 0@0 to: 150@200. backgroundGradient addStopAt: 0 color: Color white. backgroundGradient addStopAt: 1 color: Color lightGray. cr source: backgroundGradient; paint. cr moveTo: 30@100. cr selectFontFace: 'Sans'; fontSize: 40. cr textPath: 'Hello, World!'. cr source: Color green; strokePreserve. textGradient := CRLinearGradient from: 0@50 to: 300@50. textGradient addStopAt: 0 color: Color blue alpha: 0.2. textGradient addStopAt: 1 color: Color blue alpha: 0.8. cr source: textGradient; fill. image writeToPng: '/Users/kdt/Desktop/hello.png'.
This isn't anything super exciting to look at, but if you've got the IA32ABI plugin and have set up CRLibrary class>>libraryPath to point to the Cairo library, you should be able to see the output (attached). I'll try to post a more impressive demo soon.

Hi Ken,
I'm going to have 4 students working during 4 months on Smalltalk. I would like to get a Cairo working implementation. What about yours/Travis'? What can we do with it? Can we draw something in Pharo? Does it work?
Thank you
