Rendering onto an existing array with RGBA bcolor #47

Open rafaqz opened 4 years ago

rafaqz commented 4 years ago

I'm trying to render a string over an existing image using a transparent bcolor. But renderstring seems to replace the existing values instead of blending them.

Would it be useful to blend RGBA values? Or at least have a kwarg to control if that happens?
