Gets or sets a value that specifies whether to render high quality within DocumentViewer. The default is false. For providing some guarantees regarding how quickly a page can be rendered on different systems such as mobile devices, by default some parts of a page that are very complex and would take really long to render in the browser, are rasterized to an image (flattened). However as a side effect, parts of some pages may look blurry when you zoom in. You can set this property to true to disable this possible flattening (if you observe it's happening with your specific document). This way you can ensure vector quality rendering for complex documents such as CAD drawings. If you have errors due to insufficient memory, keep it at false. This setting does not effect the first step of the conversion: Source -> PDF, it only effects the second step of the conversion: PDF -> XPZ.
