Introduction

This section outlines possible reasons why some PDF documents rendered differently than expected.

Fonts are pixelated

Some PDF files contain "Type 3" fonts with glyphs (defined by PDF graphics operators) that compose squares rather than arcs. There is a limitation in PrizmDoc Viewer's PDF rendering engine where it uses large squares when converting such fonts to SVG format, which results in pixelated display.

If viewing documents that contain Type 3 fonts is important, we recommend you consider using the new Accusoft PDF Viewer which displays such documents properly.

Another possible solution is using the alwaysUseRaster mode for the viewing of such documents. See POST /PCCIS/V1/ViewingSession or POST /ViewingSession for more information.

Dynamic XFA PDF forms document content is not rendered

PrizmDoc Viewer does not support rendering Dynamic XFA (XML Forms Architecture) PDF forms. Messages such as "Please wait... If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document." or "To view the full contents of this document, you need a later version of the PDF viewer." will be displayed instead of actual form content.
