Export to PDF rasterizes whole document if you have a Motion Blur Filter apllied somewhere

Recommended Posts

I stumbled across this weird bug, that if you have a Motion Blur Filter somehwere applied, the export to PDF reasterizes the whole document instead of just the relevant layers.

Tested in Affinity Photo V2.2.1 on Windows 10.

Here is the file to reproduce it. Export to any PDF format. I used PDF (digital - high quality)

Sorry, was a mistake. Now there should be a correct file attached.

 

Make the Motion Blur a child of the rectangle, then the complete text is vector otherwise it is only the part of the text that isn't "touched" by the blur fx.

I was able to reproduce this workaround. Thank you! But it is not really a passable solution if you have a group of objects.

But the Frame Text layer is above the Motion Blur in the Layers panel, so it shouldn't be affected by it.

Nitpicking: nest to masking position, not to child position.

Otherwise impact of blur is clipped to parent shape.

For clarity: bug in app or something else?

I’ve just tried to export the OP’s document to PDF with the PDF Preset and overridden “Rasterise: Nothing” setting, and the text is still rasterised as can be seen in my attached screenshot (Acrobat Reader on Windows 10).

I looks even worse at 1000% zoom (maximum) in Firefox and not quite as bad in Chrome at 500% zoom (maximum).

And that has to be a bug.
