q16 vs q8 converting from pdf

[mtdimich]

I am trying to simply convert all the pages of a pdf into png images. It works great when I use q16, but with the same command will not generate all the pages in q8. Can someone help me out with why this would happen?

Thanks,

Matt

What is the IM version and command you are using?

[mtdimich]

ImageMagick-6.2.9-Q*

convert pdftest1.pdf -colors 255 pngoutput44.png

When I run the convert with Q16 I get all pages and when I run convert with Q8 I only get the first page.

Any thoughts?

Thanks for the help!
