Title: Saving/Exporting at higher resolutions?
Post by: Boatman on January 29, 2021, 02:39:04 PM

Hey,

I've been using REXpaint to create maps for my D&D campaign. It's been super useful, but getting it on the Virtual Tabletop usually results in a poor resolution, since the image starts off so small.
Is there a way to save the image at a higher resolution, or to make the actual characters themselves a larger resolution?

Thanks.

Hi Boatman, glad you're liking it, and neat to see another user making maps for their PnP campaign :)

To your question, REXPaint will export the image at whatever font size you're using at the time, so one option is to increase the font size before exporting, though you may have already tried that and the maximum available character dimensions are technically limited by your display (which might play a part here in case you happen to be using a laptop or smaller device).

One option in that case, if you're not already using the largest available bitmap font, is to technically enable the advanced unlimitedFontSize feature described in the manual, with which you can zoom to levels beyond those supported by your display (generally using the keyboard-based font adjustment option, pgup/dn).

Another more flexible option would be to use an outside solution, taking the exported image and using another paint program (or some free online version thereof) to double its size, for example. (Preferably using pixel-perfect scaling, to preserve the crispness, though not necessary, of course.)

What you're likely looking for is a Nearest-neighbor upscaler, which is a technique to scale images while preserving hard edges. You can find some online by searching for "pixel art upscaler" or something like that, results can be mixed. To get a decent result you must resize the image by a "perfect amount" (x2, x4, ...).
REXPaint is a bitmap editor, so the only way to output bigger images is to use bigger fonts, like Kyzrati said. That's also the reason why you can't resize the window, the ui is text-based too!
If you have a copy of photoshop available to you, it's provides a really good nn upscaler, often mentioned online. :)
