Randomly thinking about #bikeshedding when #programming the size if a #filesize #integer in a #FileFormat, though I guess it could be used for any #DataStructures in #ComputerScience.

If you know how big the largest number you're going to have to keep track of is, you can cut down on the size of the integer by choosing a number of bits that's just big enough to fit that... But there are ways you can get really screwy with this.

For example, you could choose a number that isn't the standard 8, 16, 32, 64 by going above that and using the extra bits as flags or something, like making it 24-bit and using the last 8 bits as another byte. Or you could lower the granularity, and multiply the value of whatever the number is to get bigger numbers at the expense of numbers not divisible by that.

The issue with thinking of this however is that we are talking a handful of bytes in what could be megabytes, so less than 0.1% of the byte size...

Over the past 9 months, I created a prototype for an extensible 3d model file-format for VR avatars.
I call it STF - Scene Transfer Format

Does anyone know of an image #fileformat that stores #halftone values instead of pixels?

I’m a little obsessed by beauty of this visual style (I’ve been squinting at the detail in #postcards since I was tiny!) especially for low quality images on high fidelity screens, but my experiments with SVGs are painfully bulky and can be slow to render.

I found some infamous .std files! @Thorsted, you submitted the entry to #Pronom, right? Did you blog about it too? I’ve got 100 or so that should be kept, and I’m trying to figure out the approach. #fileformat #digipres

I released libE57Format v3.0.2 to fix a small issue with standards conformance, some build issues 🏗️, and reading index packets 📇.

If you need to work with E57 point cloud files, check it out!

(E57 is an ASTM standard for vendor-neutral point cloud data files.)
