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
 
im=3DMagick::Image.read(filename).first
 
produces only images with resolutions of 72x72, which is
too blurry (I need 600x600).
I have tried
 
im.density=3D"600x600",
 
and
 
im.x_resolution=3D600
im.y_resolution=3D600
 
after reading in, and resampling
 
im.resample(600,600),
 
but without success. Is there a way to tell Rmagick what the=20 resolution
is when reading in a file ?
 
Thank you very much!
 
Best regards,
 
Axel
