Watermark feature enables to work on a report designer layout with a background. For an instance any supported type of image file can be placed as an under layer for a layout and possible to set the size and the position. When you place a watermark on a layout it will repeat in all three pages and works in flow areas as well as in static content. Following options are available when working with watermarks

In this approach the watermark image to be fetched in runtime, should be stored in "Base path for Report Designer Graphics". Therefore even watermark images has the same graphics image behavior when it stored in tool's folder structure and in runtime (For graphics path settings refer Working with Images section for more details).

Watermark image size will be stretched or shrink in order to fit into page size. In other words background image height and width will get the page height and the width respectively. Therefore the entire page will be covered with the background image, and in some cases resultant image will be distorted if the image dimension not matched with page dimensions. following shows the sample report PDF when Shrink/Stretch to fit page is selected. Example has taken the standard logo as the background watermark image and the image aspect ratio is not preserved in this situation.
This option keep the image aspect ratio as it is and will be able to re-size the image size in terms of percentage. 100% keep the original images and 200% doubled the size of the background image and etc. This option preserve the aspect ratio of the image. Following image shows the ifs_logo.gif in 200% and location as the "Center on page".
