PDF image half rasterized.

[Jean Marie]

Just wondering if anyone has experienced this before, I'm using Picture Frame to place my PDF into a page and when I export it, half of the vectors of the page becomes rasterized. Is there anyway to go about this? I want it to be fully vector.

Vectors within placed PDFs getting partially rasterized is typically a symptom of exporting objects that have transparency values in PDF format (like PDF/X-1a or PDF/X-3) that do not accept transparency. Affinity apps cannot flatten transparency any other way than rasterization, and this often shows so that a vector object has those parts rasterized where a transparency has been flattened.

Another reason (inadvertent) rasterization of vector objects within a placed PDF happens at PDF export is when the placed PDF uses PDF version that is incompatible with the version of exported PDF. E.g., all non-PDF/X PDFs will be rasterized when exporting to PDF/X-based versions, and all placed PDFs using lower PDF version than the export PDF uses, will be rasterized. But this kind of rasterization is applied for the whole file, not just some parts of it, and it does not necessarily involve transparency flattening.
