Q: preview generation layout and image attributes?

Does anyone have a link(s) to how preview images are generated?

  1. directory layout?
  2. how the image preview filename is determined?
  3. any EXIF tags that need to be generated?
  4. which indexes/tables need to be updated with newly generated preview images?

I ask as I just finished a multi-threaded thumbnail generator for linux and I could probably use it as the basis for a fast preview generator.

Any and all help much appreciated.


There was a pull request in the past:

In the repository, you’ll see the code that probably answers some of your questions.
