Was back at Urban Ore today and it was still there, looking sad on its shelf. It’s it amazing condition, powered up and and started typing with no fuss. Need to find the manual to learn how all the function work

So the good news is batching the compression is about twice as fast. The other good news is more glitch art! Eh, wait, no that's not good

There's probably an optimal batch size based on thread or core count because the compression process does completely peg a CPU core. Of course that could be either because the algorithm is churning through data or my implementation is horribly inefficient.

@thias No, I don't believe so. The bits-per-sample and samples-per-pixel are set for the whole image. Tiles are really meant to be "crops” of the full image, but I'm planning on using them in a slightly off-spec way

Ok, more interesting, both visually and technically. The whole goal of writing a TIFF builder was to implement tiling, rather than the usual striping for storing data, and here we have four tiles.

I made a TIFF!

Sure, it's not much, but it's an artisanal hand-crafted TIFF
