imAravis
Dear ImGui aravis interface
Using fake camera
With debug output:
$ ./aravis/bin/arv-fake-gv-camera-0.8 -s GV02 -d all -g aravis/share/aravis-0.8/arv-fake-camera.xml
Normal:
$ ./aravis/bin/arv-fake-gv-camera-0.8 -s GV02 -g aravis/share/aravis-0.8/arv-fake-camera.xml
How to do own GL drawing?
To draw color gradient for greyscale images from the detector I have a custom shader for openGL 3.0 that renders to a framebufer object (FBO) texture. This texture is then used as a textureID with the ImGui::Image() call.
Shader has access to an indexed image and a colormap. Colomap can be any colormap; see https://github.com/kbinani/colormap-shaders for example colormap.
