pdfpreviewterminal
I have several PNG images that I intend to include in a LaTeX document, but it does horrible things to non-vector images. I've been using preview to export the PNG as a PDF which remedies the problem.
I'd like to script this, so what would be the equivalent command in terminal to:
Pretty much any solutions considered, applescript, automator, shell etc.
I'll second that answer. I'm doing the same with PDF Expert instead of GoodReader. It is really important that you do the conversion in Skim on a COPY of the original PDF, as otherwise the PDF expert (or GoodReader, I assume) will lose the annotations, once converted (e.g., if you have your PDFs in Dropbox, which you then open either on the iPad or Mac). There is a slightly more elegant solution though. It's trivial but it avoids making a copy of the PDF:
Open the annotated PDF in Skim, convert to Skim notes, export notes to text or RTF, an then close Skim without saving. Your original PDF with notes will stay unconverted (and thus still annotated for GoodReader), but you will have your notes and highlights exported and saved.
As I said, trivial...
If you don't want any borders, create a custom paper size and change margin size to 0 as shown below:
Name your custom paper size, use it and create PDF.

This can be completed with the following Automator service workflow:
The Size Each Page to Fit option preserves the orientation of the original image(s) in my testing, so no rotation is required.
