I just found out that the 2nd command will create multiple tif files and 
although they have different sizes, each of them has the same number of 
pages of the pdf, and its content is the same as the whole pdf. ???

I thought it would output each tif file as one page of the original pdf.

So now I can have one tif file with mutiple pages, but why gs won't 
outout it without the %d in the command line ? Bugs or am I missing some 
thing ?

Thanks,
