Topic: Downsampling with ImageMagick

[pictus]

Download and install ImageMagick:
http://www.imagemagick.org/script/binary-releases.php#windows
http://www.imagemagick.org/script/binary-releases.php#macosx
http://www.imagemagick.org/script/binary-releases.php#unix

Download and unpack into your DeskTop
http://dl.dropbox.com/u/4686872/Pictus-resize2.zip
or http://www.mediafire.com/file/w47dqrjrzds3ffy/Pictus-resize2.zip
It contains some BAT files


To resize, just drag and drop any image over one of the icons in the DeskTop

The result is better than the other programs as it is free from moiré and gamma corrected during resize.

Um...wow that is a lot of stuff to absorb....

Do you have any further examples?  I'd like to see the sharpening side as well as the downsize....

Only the stuff about gamma and resize http://www.4p8.com/eric.brasseur/gamma.html
I did the final update, I guess now looks OK
