SUGGESTED FIX Either remove the allusion to setting the ZLIB compression filter, etc., in PNG from ImageWriteParam.setCompressionQuality() or modify the PNG Image Writer to allow this value to be set and used. The value returned by setCompressionQuality() may be used in a straightforward manner by multiplying it by 9 and passing it to the Deflater constructor.

EVALUATION This has caused some confusion for developers in the past; we should try to clarify or enhance our behavior in this area for Mustang. ###@###.### 2004-07-19
