Cookie plugin

Stores the settings of your current Digilib preferences and view settings in a cookie.

Geometry plugin

Required if you use the client side digilib functions in jquery.digilib.js. The plugin provides basic geometric functions which help calculating screen positions.

Arrows plugin

Adds divs containing navigation arrows around the scaled image.

Auth plugin

Handles authentication.

Bird’s eye plugin

Shows a small bird’s eye view window with the highlighted current zoom area, useful when looking at zoomed images.

Dialogs plugin

Provides dialogs to set the image calibration (for rendering the object on the image in its original size) and the scaling mode (screen size, predefined image size, or pixel of the original file).

Range plugin

Provides HTML5 range controls for setting brightness, contrast and color values of the scaled image.

Marks plugin

Allows the user to set visual marks on top of the scaled image, defining and referencing points of interest. The marks are numbered and always point to the defined location even when the image is zoomed, rotated or mirrored. The positions of the marks are part of the address. The marks are reproduced when the URL is opened in another browser or computer.

Regions plugin

Allows the user to draw visual regions over the scaled image, defining and referencing areas of interest. The regions are numbered and always point to the defined location even when the image is zoomed, rotated or mirrored. The positions of the regions are part of the address. User-defined regions are reproduced when the URL is opened in another browser or computer.

Regions can also be stored in the HTML code of the page. The code for each region may contain a link to an external resource. When the user clicks on a region, he is transferred to the external resource.

The regions plugin provides an additional set of buttons for defining and deleting regions. Regions can be queried and highlighted by entering coordinates or text.

Annotator plugin

Allows the user to add visual annotations on top of the scaled image, defining and referencing areas or points of interest. The annotations are loaded from an annotation server; new annotations can be inserted and edited. Annotations always point to the defined location even when the image is zoomed, rotated or mirrored.

How to write your own plugin

Start with the stub file jquery.digilib.pluginstub.js in the “jquery” subdirectory of your digilib webapp directory.
