Dear all,

I am having problems when reading in an image (PS/PDF/TIF):
I need to read in images of these formats, cut them in two and
export them. Unfortunately, using

produces only images with resolutions of 72x72, which is
too blurry (I need 600x600).
I have tried





after reading in, and resampling


but without success. Is there a way to tell Rmagick what the  resolution
is when reading in a file ?

Thank you very much!

Best regards,
