Image quality on resized images
Posted: Thu Apr 24, 2008 8:02 pm
I cannot see differences between setting 'quality=0' or 'quality=1' in scaling.properties.
I set 0.8 by default but I see artifacts on people faces so I made some test on extreme values.
Is there something I am missing?
I am resizing from 12Mp to 500 pixels max size.
The differences between this photos and the Irfanview's (a nice program to handle images) generated ones are appreciable.
Thank you
PS: In all quality setting the jpeg file size is 35Kb Irfanview's 42Kb (80/100 qual)
