Hi,

I have an png image that I generate (via pdf via pdflatex) that I want to scale and display in a widget. Is this possible via something in arsd? I tried resizeImage but that doesn't seem to do what I expect. Any suggestions?

Which resizeImage did you use, from the imageresize module? What pain you have with it? Some of its settings take some tweaking.

Though in a widget, you can also stretch automatically on Windows... actually XRender can do it too i believe but I never implemented that. Maybe I should.

But imageresize should work with some experimentation. This is how I did it in my image viewer application:

                           auto i = loadImageFromFile(arg);

                            auto size = calculateSizeKeepingAspectRatio(i.width, i.height, maxWidth, maxHeight);
                            if(size.width != i.width || size.height != i.height) {
                                    i = imageResize(i, size.width, size.height, null, 1.0, 0.6);
                            }

then pass that i to one of the minigui/simplediplay functions to display.
