Get the document resolution (DPI --> pixel/inch)

[joliejuke-orga]

Is it possible to get the document resolution.
I think this is an important feature since fonts size (in PT unit) should be computed from resolution.

Hey @joliejuke-orga.

The root node of the document contains the Height and Width of the document with which you can calculate the resolution.

As for DPI, I have not been able to find anything about it in the official doc. So i think its safe to assume it is not stored in the file itself.

I did however find that at 0x0435 they store display data which may contain info about it.
I have not tested this yet tho as it is something i don't have time for (barely get time to answer these issues these days :( )

I've run into the same issue. Official doc mentions resolution info being on 0x03ED. I created #132 pull request to extract this information following example of psd.rb.
