It may very well be slow, but it would be interesting to still try. One
factor to consider is that the bitmap sizes for most applications would
be relatively small, and this would reduce the amount of info to deflate.
That said - I would be open to other compression ideas, ideally ones
that will be trivially simple for server applications to implement.
One might think Adobe might know a thing or two about this subject. ;-)

Nah, png compression uses DEFLATE, basically (a form of) zip
compression. It'd be astonishingly slow in Actionscript. Simpler forms
of compression might work well if you enabled low quality before
getting the snapshot though...

Yup.. I made it using imagemagick and amfphp...
You can expect around 500kb for a 150x150px image....
I was thinking about using some kind of LRE compression, and try to
find patterns..
But PNG sound more interesting...
Can it be done ?

Hi,
I was wondering, can FP8 take screenshot of the user's activity and send
them to the server?
With the new pixel access, can FP8 send bitmap data to the server?
This would be incredible for crash reporting. In one of our apps, we have a
button where people can complain. Maybe it could attach a screenshot of the
app at the same time.
Thanks
You could take a 'screenshot', but ONLY of whats running inside your
particular instance of flash.
The only problem is, there is no image compression routines built into
flash. Also there are issues with sending raw data to the server. So
the screen capture first of all would be pretty slow (you have to read
each pixel one at a time), and then the data to upload would be pretty
big (several megabytes...unless you implemented PNG compression in
actionscript or something)
