In our codebase I write many things that, for testing, depends on the image Im loading have alpha. Usually, I make all my own testimages/programmers-art in MsPaint. But every time I need an image with alpha, I have to go and disturb one of our artists. (Or start the loading of GIMP and go for a coffee break.)
So Im looking for alternatives, as quick and simple as MsPaint but which has alpha support. I tried GIMP but the time it takes to load that behemoth makes it not an option.
Is there no software in the middle grounds between mspaint and gimp? From the looks of my googling and searching through wikipedia, most raster graphics editors aim to be a Photoshop alternative.
