Problem converting PDF to Jpeg

[sam_rh]

I am trying to convert this Vector PDF to a raster image (GIF and/or JPG)
http://u1.realtyhub.com.au/jobs/1059/fl ... s/4398.pdf

The output image looks like this

http://u1.realtyhub.com.au/jobs/1059/fl ... s/4399.jpg
(link to smaller file size if the other image is too large) http://u1.realtyhub.com.au/jobs/1059/fl ... s/4400.jpg

See how some of the textures play up (The checker pattern, and the some of the other patterns, the lines don’t seem so accurate)

Im using PHP, code something like this
$im = new Imagick();
$im->setResolution( 300, 300 );
$im->readImage( $srcFile );
$im->setImageFileName( $outFile );
$im->writeImage();

Version - ImageMagick 6.4.8

I experimenting a bit but could not get it looking any better.
Thanks.

Set your resolution to 1200 and then resize to 25%.

Thanks for the suggestion.

The checker pattern still played up in the same way. (Some of the other textures may have improved a little).
Any other ideas?

Upgrade your release of Ghostscript. We're using Ghostscript 9.02 and the results are much improved over your rendering.

I only just got my version of ghost script upgraded, everthing seems to be working fine now. Thanks for the tips.
