[gs-devel] Image resolution not preserved

[birksworks]

I'm using ghostscript to embed fonts in some existing pdf documents. The
options 
 -dEmbedAllFonts=true 
 -dSubsetFonts=false
do this for me but the images in the resulting pdf document  have a lower
resolution (72dpi) than those of the original document (300dpi).  I've tried
setting many options that could affect this:

 -sDEVICE=pdfwrite 
 -q 
 -r300 
 -dBATCH 
 -dNOPAUSE 
 -dSAFER 
 -dPDFX 
 -dPDFSETTINGS=/prepress 
 -dEmbedAllFonts=true 
 -dSubsetFonts=false 
 -dJPEGQ=100 
 -dAutoFilterColorImages=false 
 -dColorImageFilter=/FlateEncode 
 -dAutoFilterGrayImages=false 
 -dGrayImageFilter=/FlateEncode 
 -dUseFlateCompression=true 
 -dTextAlphaBits=4 
 -dGraphicsAlphaBits=4 
 -dMaxSubsetPct=100 
 -dAutoFilterMonoImages=false 
 -dMonoImageFilter=/CCITTFaxEncode 
 -dCompatibilityLevel=1.3

but with no luck.  Can anyone suggest a way to preserve image resolutions?

Thanks,
Bob
