Feature request: export screenshots with AVM

[bmorris3]

Aladin-lite can load image files with AVM,

aladin-lite/src/js/libs/avm.js

Line 175 in 7f1f699

AVM.prototype.readAVMDataAsWCS = function(oFile) {

but it can't write them. Would it be possible to embed AVM into the screenshot images exported from aladin-lite?

I like the idea @bmorris3 , I think that's doable.

Thanks! Could you let me know if/when you work it out? I'm developing the same features in jdaviz.

@tboch Also note – the AVM reader works for JPG but not PNG, so it wouldn't be possible to do a round-trip at the moment.
