You can find more infos about the project in the fx(text) linked below.
Controls : - Press [SPACE] to show/hide the user interface - Mouse wheel/middle/ Pinch : Zoom - After zooming, Mouse left / Drag : Pan
Keyboard shortcuts and additionnal instructions : - [R]eset the camera. - Toggle the [F]rame. - Unlock the [C]amera, 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"). 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.
