ImageGear Professional v18.2 > User Guide > Using ImageGear > Working with ImageGear Layers |
ImageGear allows users to load layered image files and retain image layers for editing. Users can also create new layers, delete existing ones, as well as flatten and display the selected layers.
ImageGear currently supports layers for Adobe PSD and large PSD (Adobe PSB) file formats.
ImageGear provides a set of API for working with layers. See IGImageLayer Class, IGLayer Class, IGLayerArray Class for more information.
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 resulting appearance of the image. ImageGear supports the image layers described in the next section.
Image Layer is a type of layer containing image pixels that can be applied/blended with other layers. An image from the Image Layer can cover the same area as the resulting image or just a part specified by its rectangle. Image Layer does have a certain opacity, and the other properties associated with it.
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, producing the resulting page. The result of such blending represents the final image view and is stored in the page's DIB.
