Errors accessing PDFs with PdfFormatProvider

I am working with the Telerik UI for WinForms 2020 R1 release and I am experiencing a multitude of issues loading PDFs into the Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider via a FileStream (for splitting into individual pages) that I can properly load into the Telerik RadPdfViewer using the Load() method with the file name.

Some of the errors that I am experiencing are "R24 color space not supported", "R25 color space not supported", and "currentIndirectObject should not be null". I cannot provide copies of these PDFs, as they all contain Protected Health Information (PHI), which is protected information under HIPPA.

Exporting from HTML

Hi everyone,

I am trying to convert the following quite simple HTMl to PDF

<!DOCTYPE html>

<html>

<head>

<title>Configuration</title>

<meta charset="utf-8" />

<style type="text/css">

body{

font-family:Verdana,Arial;

color:black

}

th{

background-color: silver

}

table {

width: 100%;

border: solid 1px gray;

margin-bottom: 32px

}

td {

border-top: solid 1px gray

}

</style>

</head>

<body>

<hr />

<h2>Offer Configuration</h2>

<div style="width:80%;margin-left:auto;margin-right:auto">

<table align="center" cellpadding="0" cellspacing="0" style="width:600px">

<tr>

<th>Document</th>

<th>Date</th>

<th>Sales Person</th>

</tr>

</table>

<br />

<table align="right" cellpadding="0" cellspacing="0" style="width:30%;float:right">

<tr>

<th>Total</th>

</tr>

<tr>

<td>${PL_TOTAL}</td>

</tr>

</table>

<br />

</div>

<div id="divFooter">

</div>

</body>

</html>

This is the code I am using

Dim htmlDocument = ProviderHtml.Import(My.Resources.Resource1.order)

Using output As New FileStream("c:\temp\out.pdf", FileMode.Create)

ProviderPdf.Export(htmlDocument, output)

End Using

Process.Start("c:\temp\out.pdf")

Problem is, the output is very different from source the HTML:

- the HR arenot displayed

- the tables width are ignored

Note that pasting the same HTML here https://demos.telerik.com/aspnet-ajax/editor/examples/import-export/pdf-export/defaultcs.aspx generates an invalid PDF

Is there anything I am missing?

Thanks

Cannot create a colored text background in a PDF

block.GraphicProperties.IsFilled = true;

block.GraphicProperties.FillColor = color;

does not seem to do anything.

block.BackgroundColor = color;

only colors the line, not the entire rectangle of the block.
