I created one 16x16 and one 32x32 images with Gimp, exported to png and used on a ribbon in Revit.
The 32x32 worked as expected, the 16x16 shrunk down to 5x5 pixels.
I exported the same images to ico and they showed up in the correct size.
Now I know the solution to my problem with png files: don't use them. Use ico instead.
But I would like to understand why the 32x32 work well while the 16x16 shrinks.
Any idea?
