PDFsharp | PDFsharp and MigraDoc Foundation for NET 6 | Document Editor library

I'm using PDFSharp on .net core 2.2 C#. I'm reading PDF form in my application, than I'm extract form fields and fill them with values. When I save document fields are invisible until I put focus on them (click on them).

Here is code:

I am currently writing an addition to a website that I made for work. It generates a PDF from an HTML template and then serves it to the browser so that it can be printed off.

I created a small test that works perfectly. The problem I am running into is when I coded a more complete test, nothing happens when I click the generate button. In the first page when the page loads the PDF is created and shows in the browser. On the second page I get nothing, and no error message which makes troubleshooting this difficult. The code is almost identical between the two pages, so I am really confused as to what is happening.

I will post both versions of my code. Hopefully you guys can figure out what is happening.

Is there any way to extract the coordinates and dimensions of vector objects with a specific color with C#? Like a "dieline" or a "cut line", for example? I tried with PDFSharp library, but it doesn't seem to have such function. I can extract the swatches but not the coordinates or dimensions of the objects using that respective color.

I'm using PDFSharp to create a PDF in C# and I want to add a black underline between two blocks of text, like this:

This is (part) of the code I'm using to write my PDF:

How can I get x,y location of graph wher X and Y Axis starts (x,y location of point 0,0 in line chart)? This location is changable depending on text values on Y Axis probably.

Image is for illustrative purpose only.

How can I change the background color (currently is linear blue) of chart (I use PDFsharp NuGet package)?

Sample code:

I've been attempting this for a few hours, and now reluctantly asking for help.

I have a WPF Custom Control with a backing view model that I'd like to print to PDF (via XPS). Eventually, there will be multiple pages of these controls.

Following several examples on SO and MSDN forums, I've written code that will create the PDF file with the control in it, but the content is not sized correctly.

Fair warning: This post is a bit of an essay-sized question... So let me say my thanks beforehand to whoever goes through it and tries to answer it.

Context:
I have been trying the only 2 free-commercial-use open-source html to pdf converting libraries I could find.

PDFSharp unfortunately outputs a pdf with a completely messy style layout that doesn't respect the formatting of the input HTML and sometimes doesn't output images properly. (How it should've look vs how it looks with PDF#)
TuesPechkin (wkhtmltopdf c# wrapper library) on the other hand does it all right except for only outputting these odd "image containers" (a hollow outline of where the image supposedly should be).

I declare the IConverter object upon calling my class' constructor like so:
converter = new ThreadSafeConverter( new RemotingToolset( new Win64EmbeddedDeployment( new TempFolderDeployment())));

Then I have the following method where you can find the GlobalSettings and ObjectSettings I'm currently using for the conversion.

I am building invoices with PDFsharp.

This is my SQL table (tblTripsPerMonth):

I've bound it to an ObservableCollection (PaidTrips).

The goal is to create one (1) PDF for each distinct "CompanyName" in the LicenseHolderID column. To achieve this, I convert to a List, and group by LicenseHolderID.

I just updated my PDFsharp packages from 1.32 to 1.50 and now I am getting this error that I can't convert System.Drawing.Rectangle to PdfSharp.Drawing.XRect . Is there anything I am missing or do I need to change this method base on the new package?
