Not All PNG Compressors Are Created Equal

TechSmith Camtasia

Not All PNG Compressors Are Created Equal. If the PNG compressor doesn't optimize color depth, or uses non-aggressive DEFLATE compression it can produce PNG's that are up to 90% bloat. Optimizing the PNG's in the Camtasia Relay PC recorder resulted in a ~7% (302KB) file-size reduction. With optimized PNG's, the Relay recorder's memory usage decreased ~6.5% (23,736KB vs. 25,268KB) and the start-up time decreased by ~5% (0.774 vs. 0.811 sec avg over 20 iterations).

Once a year, TechSmith holds an internal developer conference for the devs to talk about various interests they have. I wanted to implement a proof-of-concept program using vanilla C++ and an open source image library ( png++ , a C++ implementation of libpng ).
