[android-developers] Re: how to read screen data on Android

The framebuffer has two screens worth of data, stacked vertically. You can use Irfanview to look at the data and find the actual dimensions.

I'm trying to figure out how to read screen data on Android:

So, I did this on Google Nexus:

cat /dev/graphics/fb0 > hmm

Then, I looked at the file hmm:

-rw-rw-rw- root     root      9437184 2012-11-15 15:05 hmm

I was hoping the size would be something like 1280*800*4, or 4,096,000.

But, it's 9,437,184.

Groan.

Any idea what format this could be in?

Thanks.
