Conversion problem pdf to image (png)

[vincentwijermars]

I am converting pdf's to images using Free Spire.PDF for .NET 11.11.0 for .Net4.8
Running on Windows 11 X64

Basicly the code consist of:

Code: Select all

             
              pdfDoc = new PdfDocument();
              pdfDoc.LoadFromFile("test.pdf");
              image = pdfDoc.SaveAsImage(0, 300, 300);
              image.Save("test.jpg", ImageFormat.Jpeg);   


So far I had no problems, but now I get issues with the background of text that is not converted correctly
I ran a very old version of Spire.pdf that resulted in a black background of text while it should be transparent
After upgrading to version 11.11.0, I get a shifted shadow of the text
Attached the original test.pdf and the new test.jpg created with the lastest version of spire.pdf
The problem arises in the area that contains the text "vrijdag 6 maart 2026"

Vincent
