rasterize using dot instead of batik/svgsalamander #119

Closed mx1up closed 5 years ago

mx1up commented 5 years ago

Hi,

I have trouble outputting a graph to png on a raspberry pi. Enabling the antialiasing on the Graphics2D yields some weird rendering artifacts which makes the output unreadable. So this is a problem on its own which can probably be solved by fiddling on the pi, but then I thought: is it not possible to rasterize the graph using dot itself (i.e. -Tpng:cairo) bypassing the rasterization using batik/svgsalamander altogether? That would make it much faster and more memory efficient i guess and it would fix my antialiasing problem at once since I already successfully converted to png with CLI dot command with antialiasing. Or does that not fit well into the framework?

cheers matthias

With version 0.9.0 there's Rasterizer.builtIn() to rasterize directly with graphviz. However, this works only with GraphvizCmdLineEngine.
