Discover solutions for rasterization, font rendering inconsistencies, and more with PDF2XPS conversion. ### **Why is a white space separating neighboring pictures?** In some cases, XPS viewers that support anti-aliased rendering produce line/space artifacts at neighboring picture elements (e.g. for image tiles or polygons sharing common edges). These artifacts are not a byproduct of PDF2XPS conversion, but are produced due to anti-aliased rendering in the XPS viewer. The same issue applies to the input PDF document however the current PDF viewers are typically better at handling this type of issues. The aliasing artifacts should not be visible during printing or high-resolution output. ### **Why are some pages rasterized?** Occasionally, there will be PDF elements that have no equivalent in XPS. In these cases PDF2XPS will by default render the necessary elements at 92 dpi or at the resolution given by the '---dpi' parameter. In other select cases, to generate the exact appearance of the original PDF document, an entire page may need to be rendered. In these cases rendering can be disabled using the '--norender' option. Disabling rendering will preserve resolution independent properties of input PDF documents (including fonts, paths, and shadings) as well as text selection and extraction capability in XPS processing software. ### **Why are some fonts in PDF not rendered consistently?** PDF format, unlike XPS, does not require mandatory font embedding. As a result PDF consumers, such as PDF2XPS and your favorite PDF viewer, need to find substitute fonts for missing fonts on the client system. Unfortunately, this means that there is no guarantee that file will render accurately on different systems or even in different PDF viewers. Default font substitution can be overridden using [PDF SDK](https://apryse.com/products/core-sdk/pdf) which offers additional options that are not available in the PDF2XPS Command-Line Utility. To avoid font substitution errors, simply make sure to create PDF documents with all fonts embedded. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.apryse.com/cli/pdf2xps/troubleshoot.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
