Types of Layers Used in ImageGear

Layers are used to specify different elements of an image. There are different types of layers. They represent a part of an image either as image pixels or as adjustment instructions. They are stacked on top of each other, producing the resultant appearance of the image. ImageGear supports the image layers described next:

Image Layer: An Image Layer is a type of layer containing image pixels that can be applied/blended with another layer. An image from the Image Layer can cover the same area as the resulting image or just the portion specified by its rectangle. Image Layers have an opacity and other properties associated with it.
Layered Page: An ImageGear layered page is a raster image page containing the composition of layers. Layers associated with an image page can be blended in the order they appear, providing the resultant page. The result of such blending represents the final image view and is stored in the page's DIB.
