Re: How to change dpi of image from 72 to 300 ?

Wouldn't to get a larger DPI from a smaller one, would it?
Probably go from 300 - 72 DPI?

Take a look at this page: http://www.codecomments.com/archive2...-5-193544.html

PHP image functions: http://php.net/image

Heres how DPI can be changed with Imagemagick: http://de3.php.net/image#55955

With GD Lib it seems you'll have to just resize the image, resize it to 72/300 of its original dimensions. Then resize it back?

Hope that helps...
