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.
