Ability to export arbitrary sized jpg maps at a given zoom level

This is the last functionality I still use NG Topo! for and I've love to be able to give that program up completely. It allows you to export any size map image at a given zoom level which is useful when I'm writing trip reports or similar and I want a jpeg map with a track that I can save off. The CalTopo print functionality tries to lock you into set paper sizes and I can't seem to produce something like this

Any chance this could be added?

    CalTopo PDFs are 200dpi and it does support custom page sizes. So to make a 1000px by 800px image (including borders), create a custom page that's 5in x 4in. The borders will be a fair bit larger than what's shown in your screenshots, and I'll think about auto-cropping the JPEG image to eliminate extra whitespace, but that's as close as I see getting to mirroring that functionality in the near term.

    Yea, I've used the custom page size a few times but it's pretty restrictive only allowing an image 19x19 which for some trips is far too small at 1:24,000. Ideally there would be a way to make JPG images that were larger for something like this https://www.flickr.com/photos/matthewhengst/27560563714/sizes/o/

    Admittedly that's an extreme case but I do overflow the 19x19 fairly often

    Well that particular problem is easily solved by upgrading to a pro account, which lets you produce PDFs or images up to 48"x48".
