Hello all, so far I have been using DSA to gather annotations and to displaying my predictions (as polygons). I would like however display my predictions as heatmaps, pretty much as sated in this old gitter msg :
Thanks for any help!
Heatmaps can be upload like any other annotation. There are two formats: see large_image/annotations.md at master · girder/large_image · GitHub and the section below it.

Thanks David! So if I have a heatmap for the whole slide, should I list all the pixels? Wouldn’t that be a lot?
Although it is somewhat slow to load, it should work – I’m not sure I’ve seen it used with more than ~10,000,000 points though. There is a grid form which is more compact if you are doing that (large_image/annotations.md at master · girder/large_image · GitHub). In other projects, users have downsampled their heatmaps by some factor, storing only every second or forth value.
That makes sense! Thanks a lot David
