2011.07.28 18:12 "Re: Using photon lists rather than rasters", by Andreas Kleinert
If at all, then a new compression type. There are various quite exotic image formats and compression types out there. All that it needs is to ensure that the output matches a 2D raster again after decompression - and that any incoming 2D raster might be compressed using that approach. I mean, if I apply some kind of wavelet transformation and compress the coefficients later, this doesn't necessarily look like a raster anymore, either, during the process... But in this case you should write it as single strip and hide all coordinate/sub-pixel details within that. If someone wants to process the raw data, he still may do it. Or just go for a RAW format, like someone else proposed. -------- Original Message -------- Subject: [Tiff] Using photon lists rather than rasters From: Terry L.
