For our PDF to HTML5 Converter we have several different navigation bar modes to make it easier to navigate between pages.
To use these you must set the flag: org.jpedal.pdf2html.addNavBar
to one of these options:
- none
- css
- images
- thumbnailpanel_<position>
The option that adds a navbar consisting of thumbnails is a bit more complex as it allows you to place the navbar on any side of the page. It's options are:
- thumbnailpanel_top
- thumbnailpanel_bottom
- thumbnailpanel_left
- thumbnailpanel_right
The default option is thumbnail_bottom
Examples of each option can be seen below:
none
This removes the navbar, and is the default if the converted pdf has only one page.
css
This mode was our old default mode, and consists of several buttons created using CSS that allow you to navigate the pages of the converted PDF.

On a page it looks like this:

images
This mode uses a simple set of images as navigation links at the bottom of the page.

On a page this navbar looks like this:

thumbnailpanel_<position>
This mode is more complex because you can place the thumbnail panel in different locations.
From a technical standpoint this adds a slight overhead to the conversion as we not only convert the pages to HTML but also create thumbnail images out of them that are used for navigation purposes.
The various images below show the different positions and what they look like.
thumbnailpanel_bottom


thumbnailpanel_top


thumbnailpanel_left and thumbnailpanel_right
