As part of my further experiments with GTK4 and Haskell, I wanted to vary gtk-picture by creating the Picture programatically. I named the alternative gtk-dynamic-picture. Diagrams I created the picture using the Diagrams project. I looked at various backends: Ultimately, given the pixel format of a Pixbuf value (R G B A), I used diagrams-rasterific […]
