Evaluating Ibex

Users may evaluate the Ibex PDF Creator for a period of 30 days from the date of download after which time a license to continue using the software must be purchased.

Ibex runs in evaluation mode unless either:

  • a Developer License file (called xmlpdf.lic) is located, or;

  • Ibex is being loaded at runtime by an application which you have developed, in which case you can pass Ibex a runtime key (a string) using the setRuntimeKey() API.

License files are issued to users when they purchase the product. No license file is necessary to evaluate the software.

A license is required for each developer with the Ibex PDF Creator installed on their computer. Where multiple developers develop use a shared server a license is required per developer. Where a single developer uses more than one computer only a single license is required. No runtime or server licensing is required.

When running in evaluation mode:

  • the phrase "created with evaluation software from www.xmlpdf.com" or similar is printed at the bottom of each page.

  • the software will cease to function after 30 days.

Other than these two things the software functions the same in licensed and evaluation modes.
