RE: [docbook-apps] Image resolution in print.

["Bort, Paul" <pbort@tmwsystems.com>]

When you say "identify", I assume you mean ImageMagick's identify. If the "-verbose" option doesn't give you a specific resolution for an image, then it doesn't have one. Most software will then default to 72DPI.

You can set the resolution with the "mogrify" utility, like so: 

	mogrify  -density 300x300  -units  PixelsPerInch  foo.png

Hope this helps.
