Holz Posted May 8, 2021 Share Posted May 8, 2021 I found a strange behavior on PDF export: If you have a shape on a page, that has an opacity from 0-99%, than becomes the text more bold in the PDF (i guess only in PDF, i tried PNG and there was no problem). Is this a bug? Is there a way to prevent this? Shape-with-opacity.pdf Quote Link to comment Share on other sites More sharing options...

Holz Posted May 8, 2021 Author Share Posted May 8, 2021 yes i can do it. It tested it also with open sans, same effect. Shape-with-opacity.afpub Quote Link to comment Share on other sites More sharing options...

This appears to be an illusion caused by the different aliasing on the text vs. the curves in your particular PDF reader at that size. At larger sizes on a HiDPI screen they look the same.

HANDJOJO Posted May 9, 2021 Share Posted May 9, 2021 Same to me, there are no issue found in the PDF file, I'm using the monitor with full HD (1920x1080dpi), the font look same. did you tried to print out this sample @Holz? then you can compare the result. Here is the PDF in my screen monitor: Quote Link to comment Share on other sites More sharing options...
Holz Posted May 9, 2021 Author Share Posted May 9, 2021 Thank you very much for your answers, the explanation and thus solving my mystery! I use a 4k monitor and the adobe reader. I opened my sample PDF i another app (PDFXEdit9) and here the display is the same, indeed. "This appears to be an illusion caused by the different aliasing on the text vs. the curves" - Learned something again. Thanks! Quote Link to comment Share on other sites More sharing options...
kenmcd Posted May 9, 2021 Share Posted May 9, 2021 1 hour ago, Holz said: adobe reader Adobe Reader has a default setting which will darken thin lines. That setting may be why the curves are being darkened. I cannot remember the setting at the moment, but it has been discussed here in the forum before (also about odd visual results). You may want to find that setting and turn it off. My image above is from PDF-XChange Editor (which does not do this). Quote Link to comment Share on other sites More sharing options...

In Adobe Reader (and probably also Acrobat) there is an ‘Enhance thin lines’ option, but I’ve never known it to have a visible effect on text characters other than sans-serif capital ‘i’ and lowercase ‘L’.

Holz Posted May 10, 2021 Author Share Posted May 10, 2021 But if you open the PDF in Affinity, than all the text (on both sites) are actually text and not curves. Or did i miss something? Quote Link to comment Share on other sites More sharing options...

Or did i miss something? The imported curves "text" is not text, it is still curves. The only way to convert it to actual text is by using OCR.

Holz Posted May 12, 2021 Author Share Posted May 12, 2021 @LibreTraining but if you open my PDF-file in AP, then you can see it is text, and you can edit it normally. Quote Link to comment Share on other sites More sharing options...

I think I misunderstood (mis-read) your original post. I thought the text was now a "shape" as it had been converted. But upon re-reading your original post you are just saying the other shape is affecting the display of the text (which is still text). Still, I do not see any display issue with the text - as shown in my image above. So I am not sure what the issue is now. Quote Link to comment Share on other sites More sharing options...
Holz Posted May 15, 2021 Author Share Posted May 15, 2021 Well the issue is, that if you use the Adobe Reader, than the font looks more bold. To see it, maybe you need a WQHD or 4K Monitor? Quote Link to comment Share on other sites More sharing options...

Being 100%-Adobe-Free - I did not test Reader, but I did test the following at 3840x2400: Firefox browser Foxit PantomPDF editor Foxit reader Infix PDF Editor Master PDF editor Nitro Pro editor PDF-XChange Editor Vivaldi browser (chromium) In all of these both pages look the same. Made screenshots if you want to see. The problem is Adobe Reader. Quote Link to comment Share on other sites More sharing options...
