Use this value if you need to load an image thumbnail. This will only work for file formats that support storing a thumbnail, and when thumbnail is actually stored as a part of an image. Otherwise, ImageGear will throw ImGearException with error code com.accusoft.imagegear.core.ImGearErrorCodes.THUMBNAIL_NOT_PRESENT. In this case, load the entire image and create a thumbnail using com.accusoft.imagegear.processing.ImGearProcessing.createThumbnail method.

The default value is false.
