1) can be used with s-pen
2) can open files (pdf's, images) in all sizes (for example Lecture Notes can only open pdf's up to a particular size)
3) should allow for basic sorts of styling the pen (different width of brush as well as color)
4) should be able to save in the same format the original file was opened
5) should give possibility for basic sharing (gmail, sms/mms)
6) should allow to write with s-pen, and at the same time to scroll and zoom-in with fingers (for example Acrobat Reader treats a finger as same as s-pen and just draws a line)
7) should scale past the boundries (for example acrobat reader only scales till a point you can notice pixel artifacts)
I've spent some time and I'm having trouble to find app that would sattisfy me. I think that the above is something many people would look for in these kind of app, but even so, I can't trace app like that. Lecture Notes (Which I own) is great for doing notes on lectures, but is not good for taking notes on pdf's and images. There is a nice app for pdf's "Note Anywhere", but it doesn't save/export pdf's after the notes were written.
What I'm looking for is basicaly:
1) I have a pdf/png with a large size (say 10000x10000)
2) I open pdf/png in application
3) I can zoom in and scroll using fingers
4) At the same time I can take notes using s-pen
5) When I'm done, I can export the pdf/png to original format with the written notes on it
Is there an app (or as last resort separate app for pdf's and separate for images) that will allow me that?
