Hi Booxtor
ignore this, just skip to the example if you want to try

OK let's try this, open up a document, switch your document in landscape mode and find the setting so you could read any of the pages of that document in two steps.
The chances are that if you zoom to page width (cropped or not) you will have to press three times "Next page" in order to cover 1 physical page. The small "Pano view" on the tool bar will show you that after you pressed the "Next page" button for the second time, yoou are still on the same page with a small left over of that page. This left over will be shown if you press "Next" for the third time.
The only way to go around this is to determine the horizontal middle of the PDF page and to zoom exactly to that. This way if you go back or forward you will always need two moves to read a text page.

Here are two examples:
1) for this one, open the doc, switch to landscape, use autocrop and zoom to width

You need to press Next twice to go from page 1 to 2
1) for this one use the same settings as for the first one:
http://www.inference.phy.cam.ac.uk/s...tex/Errata.pdf
You will need to press the same button three times to get from page 1 to 2
In orger to get from page 1 to page 2 in just two steps you will need to use zoom between two points and you have to be able to select exactly the top left corner of the doc and the right middle point as the two points for zooming in.
Otherwise you will have the same problem as above. The problem is that the pen can not touch exactly that top corner although the image is displayed in the area that you can not touch. In other words there is a small horizontal strip at the top of the screen that is active for the reader but it can never be touched/reached with the pen
I hope it is clearer this time. For the programmer it will be a piece of cake to get the size of the page and to zoom in exactly to the half of it.
It is, if you want to call it so, a page size dependent zoom between two points: the top left corner and the middle right point
PS: the above happen no matter how loaded the page is with text.
