Download rollcall as PDF or print about webvoteview HOT 5 CLOSED

There are, I think, about three separate issues here:

1. Updating our stylesheet for print media (so that the header, footer, sidebar, etc. does not appear)
2. Making sure coloured images gracefully degrade into B&W
3. Actually implementing a print button (this is pretty trivial).

I think actual "generate a PDF" functions are more common with, say, academic articles that start as PDFs than with dynamic websites with lots of interactive components. IIRC statically rendering offline and outside a browser is relatively difficult because it would rely on terminal Javascript and SVG emulation, neither of which common browser emulators like mechanize do.

As a result, I don't think it makes sense to directly implement a PDF button.

However, most browsers now have print-to-PDF capabilities. No idea if Windows 10 does natively, but you can use CutePDF or Foxit or other options to add a PDF print driver. OSX does natively at the system level. I would assume most Desktop linux distros do as well. Probably better to just make the print function look nice and then rely on users to select PDF as a print destination.

Not sure if this is the right place, but the resolution on the PNG downloads of ideological space figures is pretty rough.

I will take a look at what it looks like right now. I am sure there are parameters to help improve the look

I would like to add here that the downloadXLS feature and code is broken.

You can now print votes using your browser's print function, and it looks good. We don't degrade our colour maps to B&W--not sure if this is plausible--but the stylesheet is updated so some of the worst intrusions don't show up when printing, and I make a few other tweaks. Either way, a high school teacher can now print our stuff!
