<div dir="ltr">Roman,<div>For the new OpenGL2 backend only 2D polygon data drawn within a vtkContext2D can be exported as vector data in a PDF or SVG. This is because GL2PS uses a feature removed from recent OpenGL versions (glFeedbackBuffer). So, if exporting vector data is important to your application you'll have to port it to draw everything inside a vtkContext2D class. We are currently doing this port for the cdat.</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Jun 14, 2018 at 11:16 AM Roman Hiestand <<a href="mailto:roman.hiestand@fluxim.com">roman.hiestand@fluxim.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hello</div><div><br></div><div>Since upgrading to VTK 8.1.1 and using the OpenGL2 backend I have noticed that when exporting to vector graphics formats such as PDF and SVG using vtkGL2PSExporter a large part of the scene is rasterized.</div><div>I have a 2D scene with a vtkPolyDataMapper and some axis (vtkCubeAxesActor2D), the camera is set to parallel projection.</div><div>When I try to export the scene to PDF or SVG using vtkGL2PSExporter the vtkPolyData is rasterized, while the axis (including labels etc) is exported in vector graphics.</div><div><br></div><div>I tried fiddling around with the parameters of vtkGL2PSExporter, but I wasn't able to achieve all-vector-graphics like with VTK 8.0 and (old) OpenGL backend.</div><div><br></div><div>Has anyone a clue how to create a non-rasterized output?
