Wrong line spacing in PDF with embedded fonts

[Tobias]

Hi! This is driving me nuts. When exporting as PDF. the line spacing is wrong as soon as I export with the fonts embedded.
The weird thing: this only happens in my production app. I can not reproduce this in a standolen app. Although, I use the exact same code:

Code: Select all

var stiReport = new StiReport();
stiReport.Load("pdf-export-test.mrt");
stiReport.Render();
stiReport.ExportDocument(StiExportFormat.Pdf, "fonts-embedded.pdf",
    new StiPdfExportSettings { EmbeddedFonts = true });
stiReport.ExportDocument(StiExportFormat.Pdf, "fonts-not-embedded.pdf",
    new StiPdfExportSettings { EmbeddedFonts = false });

Any ideas?

Hello,

On the computer where the production app is running, is the system scaling set to 125%?

Is this production app marked as HiDpiAware or not?
Because it looks like our library cannot correctly detect the system scaling. This can happen if the application is not set as DpiAware, or if it is running as a service without user permissions, or in similar cases.

Thank you.

Thanks! This is indeed the case. It's a WPF .Net8 App. When I reduce scaling to 100% OR add a manifest with:

Code: Select all

<dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true</dpiAware>

...then it works fine.

The thing is - PDF creation should not depend on the user DPI scaling preferences at all. And I consider this a regression bug, as it worked perfectly fine in
2025.4.3. Version 2026.1.1 seems to be the first version to introduce this strang issue.

Hello,

This issue did not reproduce in our tests even once.
However, we have added additional checks and a fix.

Thank you.
