_Pyramidal tiffs still require ~2s per request:_ https://github.com/cantaloupe-project/cantaloupe/issues/296 **Withdrawn.** 90 % of the problem was our `delegate.rb` without caching.

_Pyramidal tiff file size is not the problem:_ https://github.com/cantaloupe-project/cantaloupe/issues/296 **Withdrawn.** 90 % of the problem was our delegate.rb without caching.

My way (with a lot assumptions) to extract jpeg tiles in c: ```c uint32 jpegtables_len; void *jpegtables; if(TIFFGetField(tif, TIFFTAG_JPEGTABLES, &jpegtables_len, &jpegtables)==1) { FILE *fw=fopen("x.jpg", "w"); FIF(!fw); FIF(fwrite(jpegtables, 1, 2, fw)!=2);...

Would be cool if ptif generaters (like [vips](https://github.com/libvips/libvips)) would arrange tiles in [Hilbert](https://en.wikipedia.org/wiki/Hilbert_curve) or [Z](https://en.wikipedia.org/wiki/Z-order_curve) space filling curve for disk locality. → [vips issue](https://github.com/libvips/libvips/issues/2347)

[tiff-java](https://github.com/ngageoint/tiff-java) has `List getTileOffsets()` and `List getTileByteCounts()` in **Class FileDirectory**

[pica](https://github.com/nodeca/pica) seems to have [WebAssembly](https://en.wikipedia.org/wiki/WebAssembly), ~~[Gamma correction](https://en.wikipedia.org/wiki/Gamma_correction) and~~ [Lanczos](https://en.wikipedia.org/wiki/Lanczos_resampling) filter. Oh.., and [Web worker](https://en.wikipedia.org/wiki/Web_worker).

I've opened a ticket at pica: [Gamma correction?](https://github.com/nodeca/pica/issues/205)

Yes, I'll try to find out if \ (=space) is really necessary between \s in ALTO.
