Speaking of Photoshop, why was AdobeDeflate created?
Because someone outside Adobe defined a flate compression value and ignored the value defined by Adobe as part of the TIFF standard.
The non-Adobe flate compression value should be read, but never written. Use the Adobe flate compression value when writing.
