Anyone worked with super large images in a Cocoa (Mac) app? Think 300k x 300k pixels, in at least 16 bits per channel.

At very least I need to be able to read individual pixels out of a TIFF file.

Making a whole image buffer in CoreGraphics to store the decompressed file is not really feasible. Any suggestions how else I can read a subset of the image without doing this?

@amyworrall Wasn’t there sth like a tiled layer for exactly that? 🤔

@helge that’s for displaying stuff, if I can already access subsets of the image. My problem is I don’t know how to read subsets of a tiff file!
