Blank background saves as gray #21

Hi! The background looks white in my browser (Firefox on MacOS) but when I save the image to my computer, it looks gray instead. If I specifically color an area white, then that area also looks white in the saved image. See images below to see the issue more clearly. Thanks!

Hm - this is because it's being saved as a png which supports transparency.

I've had a few questions about this... would it be nicer if it defaulted to jpg which flattens it (i.e. if there's anything transparent, it'll get turned to white) — but if you want the transparent png, I can set it so if you do something like ALT + (save icon) it does png.

@jtrustad It's not saving with a gray background ... that's just how your image viewer is rendering the transparent background. If you re-save it as jpg or as png without the alpha channel, the background will render white. On Mac preview (since you said you're on mac), do file -> export, select PNG, and uncheck "alpha."

That said, it might not be bad to default to saving without the transparency channel. I suspect most people exporting their kids drawings probably want the export to look like the canvas looked in the browser.
