| PinnedTileScreenshotStore.kt |
The format with which to compress on disk. Our goals for storage:
- Store full resolution, with minimal artifacting: we don't know how we'll display the images in
future redesigns so we want to preserve them as best as possible.
- Take up minimal space: we don't have how many tiles the user will store.
WebP was chosen through testing: it produces the smallest file sizes with the least amount of
visual artifacting but is the most computationally expensive to save (2000ms WebP vs. 200ms JPEG),
which is irrelevant for our infrequent screenshots.
For file size comparisons, at 1080p, quality 50 on IMDB (a dense page):
- WebP is ~65 KiB with almost no artifacts
- JPEG is ~130 KiB with noticeable artifacts up close
- PNG is ~1.6MiB with no artifacts (it is lossless)
