PDF not coming back from database the same way it printed?

Ignition
1

Weird issue I have not run into before. Using Ignition 8.1.25, but it is using the legacy reporting component.

I have a screen where a operator can view and save a report to the database. I do so via .getBytesPDF() from the component, save that to a blob column. It then prints directly from the screen to a saved PDF (this one looks right).

Later on another screen I can retrieve the blob column to a PDF Viewer and it looks 90% the same - except the some text is now overlapping when it did not originally and did not on first print.

Right now I am likely going to tell them its a result of the old legacy reporting component and it is next on the list of things to fix for this project, but I am curious as well - has anyone seen this behavior in the newer reporting component, and also - any idea how it could happen at all? I assume even the legacy component was a WYSIWYG type PDF viewer.

I've seen overlap weirdness in various cases where alternate fonts are used. Probably related.

Does it still come back different if you use the returned bytes from system.report.executeReport() when saving in the DB?

It's the legacy component so I don't have that option unfortunately. Next project is to convert them to the new report component with that capabilities.
