Upgly pixel artefacts on PDF export from Publisher (300 dpi)

[Vosje]

Hello, I have a question. I am working on some pictures in Photo drawn by me which I placed in Publisher. So far so good, everything looks good in Photo and Publisher, but now I have tried to export a PDF and notice that the images become really ugly. The clean black lines show really bad pixel artefacts around them even if I choose high resolution (300 dpi). Why is this happening and what can I do to fix this? I need my image to look exactly the same way as it does in Publisher and Photo and I know that it must be possible in theory. Thank you for your help.

And you open the pdfs with!?
Seems like a zoom related display error.... try to open the pdf in Publisher and check if it looks the same there.

They would be much cleaner as vectors, if you don’t have Affinity Designer and you don’t want to buy Affinity Designer you could download Inkscape.

Try using these: Hearts.svg

This can be opened in Affinity Photo: Hearts.afdesign

StainX, thank you very much for your reply, I didn't even think of that. You are right, Publisher shows it as expected, no strange pixels. I was viewing it with Acrobat Reader. So if that's a zooming issue, does it mean that Publisher isn't able to produce a PDF that will be rendered correctly by Acrobat Reader? Or does Acrobat Reader do this to all raster images in PDF? That would be strange, since I guess it's the most popular program for viewing PDFs and you would expect it to display everything properly.

 

firstdefence, thanks for your suggestion. I do have Designer, too, but this is only one small part of the illustrations and they are too complex to be vectorized (a lot of hand-drawn lines, it's just easier for me to draw them naturally rathe than shape curves). Other illustrations show the same kind of distortion on export.
