I’m making an addon which takes a screenshot of all the monitors, then draws a huge canvas over all monitors (its actually in an overlaid chromeless window). I now want to create a simple photo editing canvas app. Does anyone have any experience with this? Anyone curious to chat over irc on some guidance and/or some collaboration. I haven’t ever done any canvas apps.
So far I drew the screenshot to canvas, then i drew a rgba(0,0,0,0.5) fill over it, now i want user to select an area, and as they select it should remove that rgba(0,0,0,0.5) fill over that section, and im boggled on how to do that. I also want to draw a selection box as the user moves the mouse. So it would be awesome if we could collab or you can share tips on how i can go about this.
