Higher quality DeviantArt images

[Twi-Hard]

Non-downloadable images uploaded after April 2019 can be downloaded as PNGs if you manually replace the jpg with png in the url. There's definitely a difference between the 2 versions. Here's the difference between the PNG and JPEG for https://www.deviantart.com/kingkero/art/Commission-Secret-Squirrel-Admirer-801059022 using the compare command from imagemagick

I was wondering if this is planned? I don't mean to pester or pressure or anything.. it's just I haven't been downloading because I know if it ever gets fixed I would have to download everything again anyways.

Sorry this took me so long to get to. Got somewhat burned out on everything DeviantArt, then I forgot this issue even existed, then I was sick for over a week ... excuses, excuses, I know.

Anyway, I added a png option which replaces .jpg with .png for non-downloadable non-intermediary images and this appears to work for every image.

It's just that the intermediary transform takes priority over everything before April 2019 (ID 790677560), but you can get a .png when you disable the intermediary option.

Same for is_downloadable files. Disable original and you get a .png with the same pixel information as the downloadable file as long as the resolution for these two versions is the same. It works for example here.

edit: I might combine this option with quality, since the quality value doesn't appear to make a difference for these .png files. "quality": "png".

As I hinted at earlier, this feature is now enabled by setting quality to "png" (04e4ffc).

For the "non PNG" case (an original file download is available), what setting for "quality" is used if we set it to "png"? 100?

[mikf]

quality didn't have an effect on original (or "intermediary") images to begin with, so whatever the uploader set it to, I guess.
