True, but there may be fewer compression opportunities for the png
algorithms given the smaller uniformly coloured areas and greater
percentage of transitional areas owing to antialiasing. You may wish to
run the files through pngcrush for more efficient compression:
Recompressing tldp-publishing-flowchart-small.png
Total length of data found in IDAT chunks = 90179
IDAT length with method 1 (fm 0 zl 4 zs 0)= 72925
IDAT length with method 2 (fm 1 zl 4 zs 0)= 89110
IDAT length with method 3 (fm 5 zl 4 zs 1)= 93272
IDAT length with method 4 (fm 0 zl 9 zs 1)= 74422
IDAT length with method 7 (fm 0 zl 9 zs 0)= 68122
Best pngcrush method = 7 for tldp.png (24.54% reduction)
