i'm trying to create a pdf using PdfSharpCore for Xamarin Forms but I've run into some issues.

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:

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?

Using PDFSharp, I would like to create one PDF-document for each distinct value in the property of the List I am looping through.

Grouping my collection, and creating a List:

I am trying to create a function that creates one (1) PDF-invoice for each distinct value of a property in a List I am looping through (using PDFSharp).

I grab the value of the string, and want to use it as header of the invoices (it's the name of the business getting invoiced).

To illustrate: In the following table, I would like to get the value of LicenseHolder1 (once), LicenseHolder2 (once) and LicenseHolder3 (once).

This is the method I am using:

I am working with Pdfsharp c# library to highlight the text and add annotations when mouse hover on the highlighted text.

I would like to annotate a rectangular area/highlighted text on my PDF. i.e. I would like to hover the mouse anywhere within the given rectangle area and have the annotation pop up.

It seems that a Text annotation only appears when hovering in the upper left corner of the annotation Rectangle. I tried using the combination of Rectangle and Text Annotation but that only seems to pop up when I'm hovering over the top left corner not the interior.

Can you tell me how to have the annotation appear when I hover anywhere within the given Rectangle?

I went through the documentation of PDFsharp and iTextSharp I can see only TextAnnotation example.

The PdfSquareAnnotation that I tried draws a rectangle but, pops up the annotation text only on hover of the top-left corner

Below is my code to DrawRectangle and Add Annotation from PDfSharp.

Thank you in advance

I am developing a program that creates a PDF file from the screenshot of the program window. Here is the layout/UI for my program:

Essentially for my program, I am taking a screenshot of the UI you see above, saving that as a Jpg file, and then turning that Jpg file into a PDF.

Once the program successfully converts the Jpg into a PDF, I want the program to delete the Jpg, leaving the PDF file behind. The issue arises with this IOexception error coming up from the 2) Create PDF button click event:

The process cannot access the file 'C:\Users\Aliza\OneDrive\Desktop\test14\notebook_3412312.jpg' because it is being used by another process.'

I should note that the program successfully makes the PDF like I want to, but I just want the program to delete the Jpeg file after it has created a PDF out of that Jpg file.

Here is my code from the 2) Create PDF event:

I am trying to save a created, PDF file to a location specified by the user. I'm using Visual Studio Community 2019. Essentially, I am taking a screenshot of this form:

And by using the PdfSharp external library, I create a PDF file and then save that PDF to some file location specified by the user. Here is the UI for the user to select their preferred file location:

The issue arises once the program tries to save the PDF file to the location given by the user. Here is the error I get from Visual Studio:

System.NotSupportedException: 'No data is available for encoding 1252. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method.'

I looked online for this specific error, but I don't really understand it nor what to do with it, it's very confusing. I'm still a bit of beginner when it comes to working with Visual Basic. Here's the code that tries to do it:

I'm creating a method that scans a document and it is saved as image. Then it creates a pdf document where I put the image and it is saved into the database correctly. The problem is that I just want to have the pdf in my File Browser, but the scanned image is saved too and I can't delete it. It gives me the error: "The action cannot be completed because the file is open in another program".

I use Visual Studio 2019 and SQL Server.

Is there another way to save a pdf into database without having to save the image?

This is the code:
