If you created Picture Tube in Paint Shop Pro then it is impossible to use it in other applications. TubeExtractor will convert the Picture Tube to the PNG format (which is supported by all new graphic applications and web browsers)Tube Extractor will save the image and the Alpha channel into the PNG 32. ( for example Photo-Brush supports loading nozzles from 32 bit PNG) You can also let TubeEx to separate alpha channel and to divide the tube into separate image cells.
