Manual cropping of PDF - user interaction?
I am having a bit of a challenge to accurately crop PDF files on my Kindle Paperwhite.
My interpretation of the cropping feature user interaction setup is that touching will assign the top-left and/or(?) bottom-right positions.
Now, touching with any accuracy on that screen seems to be a bit of a challenge (for me). Perhaps the following addition would allow for better cropping:
Take the auto-detected frame as the baseline. Split the screen into the four quadrants, each corresponding to one corner of the crop area. Swipe up/down in the quadrant to adjust the crop rectangle up/down; make this relatively insensitive to user input ("decelerated" touch).
I suppose that the Kindle supports swipe and touch as independent actions?
