Evaluation of xps to pdf converter

Hi,

     We are evaluating Aspose pdf for one of our products. Our requirement is to convert wpf xaml to pdf.  We are evaluating the xps to pdf conversion features of  your component.
     We would like to know the following

    . We are unable to completely evaluate the product since in evaluation mode the conversion of pdf from xps is restricted to 4 text fragments (At most 4 text fragments can be added in evaluation mode. ). Is there any other option of evaluating the same , which is not restrictive of the size of file being convereted.

•    Is there any limitation on memory/file size of the xps file being converted to pdf in licensed version. In 64 bit mode, the reading of the xps file which is about 95 Mb approx
    Takes long time and never seems to complete.

•    Also, Do you provide option of converting custom xaml code to pdf without having to parse the xaml code ourselves and write corresponding pdf element to pdf file, i.e pass a xaml ui to sprire.pdf which can do the parsing on its own and convert to pdf (without xps conversion in between)?

Thanks,
Balaji R
