Is it possible to convert a bitmap to alpha transparency using an effect or some combination of opacity settings?
Something very useful that Fireworks allowed was a quick “Convert to Alpha” setting, and then adding a color fill. This allowed you to quickly remove a background, and then set the primary color of the image using a fill.
So much of web work involves alternating in/out with transparencies on bitmaps and lossless presentation of vectors (text, css, svg…), so allowing a quick conversion to Alpha on bitmaps saves a ton of time when trying to chop a couple of bitmaps together.
While I get Gravit’s usefulness as a vector illustration tool, one of the big reasons I use design apps is for mockups, and mockups aren’t all illustration/vector based. They involved chopping up bitmaps, screenshots, Google images, photos, etc. Allowing users to easily do all this I think is why we don’t understand the hard line between illustration and photo editing. Mockups ARE design, to me and to a lot of people. So Gravit Designer having a toolset to help us mock things up would be powerful.
