+If the native size of the document is not appropriate for your use case, you can specify settings which
+will control the size at which it will be rendered. Selecting "Override DPI" and changing the "DPI" option

+You can also specify the page size Ghostscript uses when interpreting the document by selecting "Override Page

+document to fit this page size or not as well, but that option is specific to PDF documents.
