Yes, I’m a little old school when it comes to wireframing and prototyping: I use Omnigraffle. During the years I’ve accumulated a lot of Omnigraffle stencils and templates, and I know a nifty shortcut or two that speeds up my work flow. Lately, I’ve been using InVision for web, mobile, and wearable prototypes. However, exporting my graffle screens to png:s has turned out to be a little tedious since the option of exporting “Entire document” usually gives a lot of whitespace on each screen, which looks bad in the InVision experience. And manually exporting 30+ screens several times a day is just a waste of time. So, I wrote a little AppleScript (see, I told you I was old school) that automatically exports individual Omnigraffle canvases in the right size to png:s.
You can probably get more fancy and use this in Automator sequences, or if you have the AppleScript icon in your menu bar, you can start your scripts from there. I often run the script right from the Script Editor app. Oh, well, here’s the script. Enjoy:
