Alpha Blending Image Filter

Alpha Blending Image Filter

         Aspose.Imaging library provides the Blend method to achieve alpha blending image or photo effect. Using this image filter on a background creates the image effect of placing the overlay image over a transparent layer on top of the background. The `Blend` method allows you to specify the coordinates of the point on the background where you want to place the overlay image. Overlay images can be inserted with varying levels of opacity, ranging from 0 (fully transparent) to 255 (fully opaque), known as the "overlay alpha" value.

         In the Python example provided below, we show a semi-transparent overlay image with an opacity level of 127 placed in the center of a background image. The resulting image is then saved to an output file.
