HOWTO: Print Multiple Images

The following is a simple example how to print multiple images to a single page. The key concepts to takeaway is the setting of the GetImage event. Images would print one per page if we used the ImagePrintDocument's SetImagesFromImageCollection() method. By overriding the GetImage event it allows us to control how the printing occurs. Another important method is the AtalaImage.Draw(). It is overloaded so it has a variety of parameter options. There is an important parameter in the method called renderBottomTop. Please be advised this will default to false when using one of the overloaded methods that does not pass this value. In order to print color images a value of true must be used.

                y = y + 1000;
