Controls : - Mouse wheel/middle/ Pinch : Zoom - After zooming, Mouse left / Drag : Pan - Press [r] to reset the camera. - Press [f] to toggle the frame. - Press [c] to fully unlock the camera, with rotation on Mouse2. - Export a PNG capture at various resolutions by pressing the number keys [1] to [9] (top row or numpad, and only in live mode, after pressing "open"). Resolutions ranges from 720 to 7680 pixels for the smallest dimension. I recommend starting with [4] and going from there. What is captured is what's on screen, so you can get creative if you so desire.
