When using zoom and pan features, the initial display size of the viewer window and the image is controlled by values in configuration files stored on the CONTENTdm Server. The default settings can be defined by both the CONTENTdm System Administrators and Collection Administrators, applied globally or to individual collections.

Zoom and pan default settings can be changed in CONTENTdm v. 3.7 and the JPEG2000 Extension; the process is the same.

The settings are stored in a configuration file, imageconf.txt in the Server conf directory. The function of each setting is described within imageconf.txt file. Additional details can be found in Zoom and Pan Settings in System Administration.

To make global changes to all collections:
Open the imageconf.txt file located in the Server conf directory. Edit the existing values that appear any command line which is not preceded by a # symbol.

To override global settings and make changes to individual collections:
Copy the imageconf.txt file to the index/etc directory of the collection. Edit the configuration file here and save your changes.
