          Why not just open the file? Once loaded in memory it is uncompressed.

            and i have retrieved the each layer image data from tiff file. and the data of each layer information is compressed zip type. so i want to decompress that each layer image data and i want to create PNG image from that image data.
            thank you


            Is this a SDK specific question? Is it action specific? If scripting, is this ExtendScript or UXP?
