I Downscaled Some of My Geocaching Photos to Use as Phone Wallpapers

Since the cellular antenna on my Xperia M4 Aqua had pretty much given up, I had no choice but to send it in for repair and buy a new phone. Maybe there is some kind of phone rental service out there, but I haven’t even heard of the idea yet, let alone seen it put into practice. And because it’s Sony never again, my choice in a reasonable price range came down mainly to the Huawei P8 Lite and various Xiaomi models.

Although the Xiaomi phones were better in most respects, they didn’t support Czech LTE (only up to 1800 MHz), so they were out of the running. A phone that’s nothing but trouble, that’s Sony, just like with another Xperia last year. Hopefully it won’t be all moaning and groaning now that the new phone is a Huawei! It all started a few days ago when I set aside 999 photos out of roughly 1600. The text of my post on Google+/Fb explains why exactly this three-digit number and what it’s all about:

  • Photos from 3 countries (so far I only have caches in Slovakia, Poland and Absurdistan)
  • CWG from 3 years (2014, 15, 16)
  • I can’t even manage a thousand 🙁 3 x 3 = 9 ” x 3 ” = 999 🙂

I picked the photos only from this album: 👻 The page moved out and left no forwarding address. you wouldn’t find them there, but that’s because I don’t have to put everything on display there 🙂 They are split into 2 albums, because Google Photos supports at most 500 photos per 1 album: https://photos.google.com/share/AF1QipP2uXboeMuHBSZj9N4kdsqJ0ZJ5V_J7fiYfH3rNcwb20Z2GZWDbDkpswI2BgJGbyg?key=YURvOUc4U084WTJabkFDbDk3X0dma01URDRyakJB https://photos.google.com/share/AF1QipNFFxrATZJr7sVKJ_05dJhHXscGcFZCdzGux0tfFVpN2vg4SHlr7Gp02NtblK5Ksg?key=cjl4UC0xa2JwVkdZSlBHNk5QeHFMNGphUXkycUdR   I set these photos as my desktop background in Windows, so every 30 minutes it switches to a different random one.

I wanted the same for Android, so here is what I did:

  1. I checked the resolution of the Huawei phone – the standard 1280×720
  2. I checked the resolution of all 999 photos – only 497 had a higher resolution in both dimensions
  3. I downscaled them to 3 Mpx in XnConvert, which turned, for example, 4608×3456 into 2000×1500. If I had left them that large, the output would be centered, but it would show only a small rectangle of the original photo. One photo failed to downscale, but I’m not bothering with it.
  4. I wrote a small C# script that detected the resolution of each photo and generated a script for ImageMagick (see the image below)
  5. Ran it and that’s it 🙂
