Hello,

I am creating Charts using phantomjs + Charts and want to integrate them to my PDF file.

In the attached file Original.png you can find the original image I am loading into the pdf.

In the attached file PDF.png you can find a screenshot of how the image looks in the pdf.

Attachment:
PDF.PNG
PDF.PNG [ 39.33 KiB | Viewed 10407 times ]


The Code for integrating the image is as follows:

Code:
    var image = new Image(vsChartImage);
    image.Width = Unit.FromCentimeter(15);

    Table table = document.LastSection.AddTable();

    table.Borders.Visible = false;

    Column col = table.AddColumn();
    col.Format.Alignment = ParagraphAlignment.Left;
    col.Width = Unit.FromCentimeter(16);
    col = table.AddColumn();
    col.Format.Alignment = ParagraphAlignment.Right;
    col.Width = Unit.FromCentimeter(8);

    Row row = table.AddRow();
    row.Cells[0].Add(image);


Here vsChartImage is the path of the Image.

How can I remove the borders drawn around the image?

Hi!

I pasted your code into the Hello World sample and I don't see any borders. I used "Original.png" instead of vsChartImage and opened the file with Adobe Reader XI.

Time for an SSCCE.

I now first tried to comment out every step until the problem didn't exist anymore.

I then went one step back and copied the code to a new console project. (

)

When I now run the new project I can't reproduce the error.

The only difference is that the live Code is an ASP.Net project and the code is called from WebAPI.

The locally saved files of the web application have the bug in them, while the ones generated from the console project don't.

Any ideas?

Have you tried both builds (GDI+ and WPF)? Maybe the other one works on the server, too.
Or try a server with a different Windows version (if available).

Sadly neither GDI+ nor WPF give the desired output.

I tried with both stable and beta versions from NuGet.

Any other idea? I will try to build a small website for recreating the error.

Can you try other formats than PNG (GIF, BMP, TIFF) or maybe different PNG files?

The PDF files created on the server are different from the PDF files created on the workstation, right?
Are the PNG files identical?

Both programs are running on my local machine right now.
One is console application the other one is a website running on my local IIS Express.

The console application puts out everything just fine, while the web application has this problem.

Mysterious.

Are you embedding generated charts or are you reading the chart from the same PNG file?

Same .NET versions for both projects?

I am embedding generated charts (in png format) in the web application.

In the console version I embed one of the generated pngs.

Also it's the same version of .Net and PdfSharp/MigraDoc

Seems like an error in Adobe Reader.
A colleague using 11.0.5 doesn't have any borders, while I have borders using 11.0.10.
But still it seems weird that I don't have the borders in the console application.

I found the problem, but not why it was there only in some cases.

The problem was with phantomjs (the headless browser used to generate the images). Here a transparent background was used. it was 1px around the image. Since the image was resized when put into the pdf the border was probably less than 1px and sometimes appeared as a border.

Setting the background color to white helped.
