Matt:<div><br></div><div>I'm using pylab. One thing I'm going to change is modify it so that it gets the resolution of the image, then sets the pylab figure size based off that. I'd also rather have this go through freetype, but the development time for that for me is >> (time left this afternoon). I'd be +1 to porting to freetype. </div>
<div><br></div><div>This is _very_ loosely coupled to the interactive camera. I'm going to (right now) move it over to the general camera class, and make it have the API:</div><div><br></div><div>cam.save_annotated(fn, im=None, enhance=True)</div>
<div><br></div><div>This will take the filename, the previously produced image array or try to get the cam.image array (which exists for some variants of the camera), and then apply the standard deviation clipping that is presence in the enhance.py on the hub. I'm going to strongly encourage the enhance=True. I've been making movies that use the same normalization and have been happy with all of them.</div>
<div><br></div><div>While I'm at it, I'll add a cam.save(fn, im, enhance=True) that skips the annotation.</div><div><br></div><div>+/- 1 on those additions? Requests?</div><div><br></div><div>All others: Thanks for the enthusiastic response!</div>
