GT is So Cool!!

by Sean P. DeNigris

Holy #@$! what a difference GT makes. Consider the following side-by-side of a HOCR object returned by Google's Tesseract OCR Library. The left shows a traditional inspector, the right shows the lines of OCRed text. The traditional view is pretty much useless, but the right side tells you quite a bit about the object in domain terms. <http://forum.world.st/file/n4810054/Screenshot_2015-03-06_11.png> ----- Cheers, Sean -- View this message in context: http://forum.world.st/GT-is-So-Cool-tp4810054.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

For the compilation, I mean. (the two .h happily contain code to define those two macros ??) Ok, conclusion with a brand new VM: stuck at the very first test. The worst result of all :( Thierry

Using Pillar on Windows

by Jean-Christophe Bach

Hi, I was trying to use Pillar on a Windows computer and I discovered that there is no nice script to download and use it as for GNU/Linux. I was wondering if there were Windows users who did it. If so, it would be cool to commit it on Pillar repository. JC

Re: [Pharo-dev] [ANN AthensSketch] A playground for drawings with Athens.

by Nicolai Hess

There is a "play" button in the SketchBrowser. And if you open just the simple sketch view: ASketchExampleColors openView you'll have to start the drawing from the morph menu. In a prior version I had some "autoplay" option, but sometimes this throws a NativeBoost error, if it is the first time it loads the cairo library. Maybe I should add the autoplay again. 2015-03-06 16:03 GMT+01:00 Torsten Bergmann <astares(a)gmx.de>: > For me all the samples stay black.
