There is no need to wait for the page to finish being drawn, go ahead and change pages, zoom, select a new file, etc.
Drag the page with stylus or finger, or use arrow keys.
Up or down arrow at end of page will change pages.
Type a page number and return to jump to that page
.
Type in letters to search for strings. Hit return (or Okay) to search again for the same string.
Notes
There are three view buttons: PDF, Text and Notes.
Notes are created by tapping on selected text in PDF or Text mode. In the PDF view, text selection mode is turned on and off by either tapping in the document window, or tapping on the PDF view button. When text selection mode is on, an "I" cursor will appear over the PDF button.
In Note view, text can be added to notes. Jump to a note by putting the cursor on it and switching to Text or PDF mode. In PDF mode, tap on yellow highlight to view note.
All the notes for all files in the directory of the current file can be loaded with "Load directory notes". This allows direct indexing for a set of files.
Gestures
Gestures are especially useful in full screen mode when the menu bar is hidden.
Edge tap gestures can be used at any time.
- Full screen on/off => tap top edge of document window (also Fn-5 on c7xx)
- Next page => tap upper right corner of document window
- Previous page => tap upper left corner
- See page number => tap lower right corner
Drag gestures are started by using the space bar (or wheel center on 5x00), or the okay button on the edge of the C7xx when it is folded in portrait/tablet mode. Cancel exits gesture and full screen modes.
- Rotate screen => drag in a circle
- Zoom in => drag a diagonal across the area to zoom in on
- Zoom out => drag a horizonal or vertical line starting from the side of the document window to move inward the distance equal to the extra page you want to see on that side.
- Undo zoom, multipage find, open, page menu => drag left (not from edge)
- Redo zoom, multipage find, open, page menu => drag right (not from edge)
Other features
Explore the menus. Hopefully you can figure them out.
- Page > Set Page 1 => useful if the document's page numbering does not start at page 1.
- Edit > Find => holds find window on screen, arrows allow multipage searching forward or backward.
- Edit > Forward/Backward => goes back to previous views after zoom or file change
Fonts
"Adjust spacing" will attempt to improve letter spacing when there are no embedded fonts. (the spacing is bad because of font substitution)
"Embedded fonts" will render type 1 (in "render" version), and truetype, type 0 and type 2 fonts (in "freetype" version). This is slower, but much prettier.
Type 3 fonts often have irregular character positioning, have no text view, and don't allow word selection.
Sometimes symbols are embedded fonts, while text is not. In this case, setting both "Adjust spacing" and "Embedded fonts" will cause symbols to appear the wrong place relative to text.
If there is no text view, the PDF could be a scanned image, or use type 3 fonts.
Bugs
Bugs, suggestions, comments are welcome. Please include PDF file and complete instructions to reproduce the bug.
If qpdf runs low on memory, large images will be resampled at a lower resolution causing fuzziness.
