We should change that and use the properties of the node.

[Athens] Finding if a line passes through a specific pixel .

by kilon alios

So here we are with my first challenge. I am making Hyperion, a vector graphics editor using Athens , so far I have a nice line with several segments, I have added nice handlers to allow me to move the points (start and end of each segment) of the line around with the mouse, but now I want each time I click on a segment itself to create a new point.This way I will create more points with the mouse and bring more detail to the shape of the line / path. In order to do that I will have to check that the line passes through a specific pixel. Or to be more correct that the place that mouse has clicked is where my path passes through. How I do that ? Can Athens do that ? Can athens tell me which pixels my path passes through ? At first I thought to return the Athens surface as a Form but the form will give me back the colors of each pixel on a specific place, but that does not guarantee that my line / path passes through those pixels.

Hi Stephan, thanks for testing it, when I have some time I will work in the transformation because is a big missing feature. If you want to contribute with the project tell me your smalltalkhub user to add you :) Sorry for the lack of support, as Stef said I'm in the middle of a workshop planning for this saturday. 2013/11/14 Stephan Eggermont <stephan(a)stack.nl> > > On 14 nov. 2013, at 19:39, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> > wrote: > > > Gisela is busy preparing a workshop in argentina and working. > > Now did you try to load it? > > I do not know if there is an automated jenkins build. > > Gisela contacted me, and I managed to load the newest version. > AST-Core is changed in Flamel by adding instance variables to > RBProgramNode. > That breaks each time AST-Core changes in Pharo. > Still 2 failing tests (already on Trello), and the transformation needs > work. > > Stephan > > > >

Gisela contacted me, and I managed to load the newest version. AST-Core is changed in Flamel by adding instance variables to RBProgramNode. That breaks each time AST-Core changes in Pharo. Still 2 failing tests (already on Trello), and the transformation needs work. Stephan

Looking at the code I notice that it looks for libGL.so under /usr/lib/libGL.so. In modern versions of 64 bits Ubuntu, and Linux Mint which is derived from Ubuntu, libGL.so is not placed under /usr/lib, instead is placed in a driver dependent folder, which is referenced by a config file in /etc/ld.so.conf.d/ . With a mesa driver, the OpenGL library is at /usr/lib/i386-linux-gnu/mesa/libGL.so.1 , so the driver shared object path cannot be hardcoded. The path problem is a know issue, yes. If you have a good solution. But yes basically you have to update manually the pass in the moduleName variable. > Changing the module name for 'libGL.so.1', doesn't work, but changing it for '/usr/lib/i386-linux-gnu/mesa/libGL.so.1' gives me an 'unable to resolve external type: GLXDrawable', adding NBGLXTypes into the pool dictionaries of NBGlxAPI solves it. I fix that too. > After changing that, it tries to create a multisampled framebuffer, however it doesn't check the maximum number of samples supported.
