screen captures are a little problematic, since
the image size depends on your display resolution.
If your application window spawns the half of the width
and height of your display and your display runs at
1024x768 pixels the your capture will always have
If you now want include this image in your document
with width 4 inch and it should be printable on a
600 dpi printer then the image size should be about
1200x900 px. That is a resolution of 300px per inch,
but it should be enough for the printer to interpolate
The only way i know, is to scale the image in a graphics
programm (The Gimp, PhotoShop). After scaling you
should blur the image in order to reduce the pixel-effect.
