File extension ptif is mainly associated with the Pyramid encoded TIFF bitmap graphics file format. Multi-resolution TIFF containing successively smaller versions of the image down to the size of an icon.
Better Portable Graphics (BPG) image format created to replace the JPEG format; provides the same quality as JPEG images but in a smaller file size; supports lossless compression; natively supports 8 to 14 bits per channel.
