If LodePng doesn't work, there's this actionscript library 
(http://code.google.com/p/as3corelib/source/browse/trunk/src/com/adobe/images/PNGEncoder.as) 
which probably wouldn't be too bad to port (~100 lines).  It uses a gzip 
compress function (line 88) that's part of the standard actionscript 
library 
(http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/flash/utils/ByteArray.html#compress())--I'm 
not sure what's available in D.
