Why does my image becomes darkers and low resolution when export to PDF?

[hana]

Hi all,
I'm having a problem exporting my image to PDF in Visio (Microsoft Professional Visio 2019 on Windows 10).
I have a scalable vector graphics image (svg).
Here is how the image looks opened in Chrome or Forxit Reader which looks good.

Now I open the svg image in Visio and then export it to PDF with these settings.

Finally if I open the resulting PDF image in Chrome or in Foxit Reader and now you can see that the image looks different from my svg image and the yellow background part becomes darker.

Also if I zoom in the lines look broken and look like it has low resolution.

I tried it in my other laptop and the problem doesn't have one my laptop. I reinstalled Visio to be the same version as the one in my laptop but it doesn't solve the problem.
Does anyone know what problem is this and how can I fix this?

I'm going to attach my svg image and PDF here in case you need to examine them.

I used another PDF printer ( https://www.pixelplanet.com/product/pdfprinter/ )


One print is out of Visio the other from Inkscape.


Analyzing the svg itself - with visual studio code and by ungrouping it in visio you notice that the cuves are not lines, but surfaces. That's probably why they get pixelated.

Why do you complain? @Visguy it is easier to help - no restrictions by moderators, uploads, ...

Why do you complain?

The discussion in the SO-forum began early, with several users offering advice

I agree   
It is a pity that the Simple Machines Forum engine does not allow you to add BBCodes to embed videos, view documents, etc.

Thanks, the image was exported from Mathematica so probably why they're surfaces that way.

I wanted to say try other PDF printers (or even the export as pdf function from visio)

Actually I did try several  ones and export from visio as well before asking but they all have the same problems.
I'm going to try the one you mentioned and see if I works.
I thought the problem was related to the svg image but now I see it doesn't seem to be.

Also why is this forum verification so bad? Every time I made a question, or comment and submit it I have to try for more than 10 times before it works even though I answered all the questions correctly.

I have none of the difficulties you describe. That would be something for our admins!

The very 1st time that you try to create/comment on a post, you must become a registered member.  Until that happens, you can read only.  After that, you need to be logged in to become "interactive".  Log-ins time out, the duration is specified at log-in.  Once logged in, then you can undo your seatbelt and are free to roam about.  Occasionally, an account is flagged for abusive/inappropriate behavior.  That normally prevents you from logging in.  But, for a normal acct, there are no restrictions, no repeated submissions.  Might there be a security restriction at your end?  I believe some restrictions might inhibit proper forum operation.  I do not have sufficient clearance to look into such high level behavior.

Unregistred visitors cant create posts there…

True.

This is annoying that it is telling me wrong for more than 10 times before it works.
