Re: [Pharo-dev] [Moose-dev] Roassal visualizing a corner of the Universe

by Chris Cunningham

So, Hannes may have been referring to optimizing the slow parts of the process in Native Boost directly instead of using an external library (if not, may I suggest it?). It is possible that just a few tweaks using Assembler in the process would get the speed up to an acceptable level, which would be determined by profiling the performance. Of course, that path requires someone on your project that can understand Assembler to get familiar with NativeBoost. -cbc On Thu, May 8, 2014 at 8:05 AM, Alexandre Bergel <alexandre.bergel(a)me.com>wrote: > We will surely review all the different options for interacting with > external libraries.

Re: [Pharo-dev] Starting making bindings for OpenCL using NativeBoost.

by stepharo

Hi ronie Some questions: do you think that we could have a openCL back-end for athens? do you think that we could avoid having openCL text inside Pharo but have a kind of DSL?

We will surely review all the different options for interacting with external libraries. Ronie is our local expert :-) Currently, we have no preview of the Roassal book to share.

If you want to do that in vector graphics you should use Athens (I'm finishing a chapter but it is really draft) You should have a look at the Athens tutorial that you can find in the Athens repository. You will probably need to port the drawing methods of star and other basic morph if you want to use them with Athens. > 3) Save this and generate a PDF.

Application development - import image and mark it up with vector graphics and create PDF

by Reg Krock

Hi, What is involved in creating an application in Pharo, part of would which do the following: 1) Copy an image (ex: jpg) into a a window area. 2) Allow the user to add basic shapes on top of the image - square, circle, with text inside the shape. 3) Save this and generate a PDF. There is business domain logic surrounding this. Regards, Reg
