The example demonstrates how to overlay an image with a transparent image.
LabVIEW Vision Development Module (VDM) by default does not support transparency information within PNG files. However, PNG files can contain additional information specifying the level of transparency of every pixel, called alpha channel. Since the VDM does not support transparency the example sets a threshold to decide if a pixel will be displayed fully opaque or fully transparent. Depending on the previous evaluation the transparent image is projected onto an existing image at a certain position.
