How do you do "-density"?

I'm reading in .ai and .pdf files and they look pretty bad. How can I set the -density using MagickWand?

I read in my searches about this that the default dpi is 72. Can this be changed?

Thanks in advance,
Eric James

The -density option sets the x and y resolution of the image. You can set the units and resolution of the image with these functions which both return a Boolean result. Call them before you read the image.
// units are PixelsPerInchResolution or PixelsPerCentimeterResolution - I don't know the PHP name for these constants (I use C).
// x and y resolution are doubles.

Those changed did not make a difference. For now I ended up just using exec() in php so I could use -density. A bit frustrating.

Anybody have any other info on setting -density using magickwand?

Thanks again,

I guess MagickSetResolution should be used instead of MagickSetImageResolution.
