Curve with arrow head gets rasterized in PDF export

Recommended Posts

Hi,

using Affinity Designer 1.7.3.481 on Windows 10 Education 1803.

When PDF-exporting a curve with an arrow head, the curve gets rasterized. It seems to be connected to having an arrow head, since the same object without arrow head does not get rasterized:

arrowPdfExport.pdf

I would expect the arrow-head curve to not get rasterized. Is this a bug? Does a workaround exist? I have also enclosed the afdesign file.

Regards

arrowPdfExport.afdesign

Can confirm this weird behaviour / bug. To prevent rasterisation, remove the fill from the lines with the arrowhead.

Perfect, thanks a lot for this workaround!

 

Still, it would be great if this got fixed sooner or later.

In Designer 1.8 beta (I have not tried 1.7), the Fill of both lines is white, though the lines display as black. The exact fill color is H:0, S:0, L: 92, and perhaps the saturation of 0 is acting something like having an Opacity of 0 and causing rasterization upon export due to the export settings and the need to rasterize transparent objects based on those settings.

I'm not sure why it only affects the line with the arrowhead.

In addition to the workaround Walt has said

Which workaround? As long as the line with the arrowhead has a fill - no matter what kind of fill - rasterisation is on.

Sorry I could have phrased that better. After Walt's finding removing the fill will allow it to export, which in the attached document's case will not change the look of the object.

OK, I thought it was about Walt's assumption about opacity. ;)

Removing the Fill was actually @Joachim_L's workaround. I just commented on an oddity about the characteristics of the Fill, and speculated on what might be happening.
