If you are evaluating the product, please select the ImageGear Evaluation License option from the initial screen of the AccuSoft License Manager utility. An evaluation license will then be stored on your computer. An Evaluation license enables you to use any features of the product on your machine with your choice of either a trial dialog that periodically appears or a watermark over images. To toggle between these two modes, use the IG_lic_evaluation_mode_set API function.
