In version 2.0 it is possible to convert EPS into PDF using the pre-existent conversion step "change-format": if the input file is an EPS/PS and the format requested is "image/pdf", the parser apply the EPS->PDF conversion.
There are also one more integer step parameter in change format: pdfResolution, is used in EPS->PDF conversion, determine the size and the quality of output (default value 72)
An example using parser.exe:
parser.exe d:\1570.eps -convert ChangeFormat -p:string image/pdf -p:int 90 -p:int 300
(Note: the required paramemter "-p:int 90" is the parameter for the jpeg quality, and it is not used in this case.)
