After opening of a new PDF Document often we have to adjust the page size (Page Setup). In most cases we don’t want to see to big margins of original document. So we can use the “auto crop”, ”Two point” tools or also just set cropping value manually as XX.
Once set - the page settings - are hereafter effective for entire document and virtual page boarders should be handled as real boarders ( moving of viewport behind of that boarders is not allowed. Changing of the page settings of the current document is always possible. You can also reset page setup whenever you want.
Don’t confound page setup tools and zooming tools! Zooming tools are actually just tools, which could be applied on a document, where the page settings are already set. Zooming tools have to respect the by user applied page settings.
In “Reading menu
” you can switch between two Reading modes -“Page mode
” and “Scrolling mode
In “Page Mode
” we have additionaly two viewport navigating modes “Paper
” and “Comic
(in future update additionally, for customers, who read from right to left, we will add this toggle for reading direction: Left-to-Right/Right-to-left)
(by first opening of a new document):
” is on and “Paper mode
” is on (in "page mode" either "paper" or "comic" mode are almost always on!)
How do zooming tools and hardware controls work in those modes?
General for all modes:
- With joystick you are able to adjust the visible area horizontally (5% of the displayed scaled area).
- With up and down joystick movements you are able to do zoom in / zoom out of visible area (same like wit (+) /(-) icons
- By moving of viewport with “<” “>” buttons next viewport starts there where previous ends with a small overlapping
- The boarders of the last applied viewport are displayed as interrupted/grey lines.
- With zooming tools (zoom, custom. zoom, two point zoom ...) you can scale a particular area. Current viewport position will be displayed also in viewport icon
1. If "Scrolling mode
" is on (paper/comic mode icons and settings do not have any effect in that mode)
a. With “>” “<” buttons you scroll vertically to the next/previous viewport. Next viewport starts there where previous ends with a small overlapping
b. In this mode it is allowed to show parts of the next/previous (remember! possibly cropped by page setup) page at the same time (if the viewport area displays the end of the last and begin of the next page as a kind of scroll.)
2. Page mode
If the current viewport is as big as the cropped page with “>” “<” buttons you can move the viewport to the next page.
a. Paper Mode is on (standard settings). If zooming tools were applied to the page and the viewport is smaller than current page, with “>” “<” buttons you move the Viewport vertically to the next/previous viewport on the same Page. After achieving of the bottom of the first column on the current page, the viewport will be moved to the top of the second column etc. You have to do it as long as the page is not scanned completely. Afterwards viewport will be moved to the next page
b. Comic Mode. If zooming tools were applied to the page and the viewport is smaller than current page with “>” “<” buttons you move the Viewport horizontally to the next/previous viewport on the same Page. After achieving of the right end of the first row (right edge of the page), the viewport will be moved to the left of the second row etc.
