Writing Text Fragments causing extra fragments to overlay drawn lines

Aspose.PDF Product Family
1

I am writing text fragments to a location and there seems to be an extra fragment created. It ends up sitting over the existing line and i cant determine where its coming from. I also have no way to “send back” so its on bottom of the stack.

I have attached the following files:

  • BlankExample.pdf - the original document that i am writing too.

  • TextWritten0.pdf - The document after I have written text fragments to it.

  • TextWrittenExtraElementAppears.PNG - screen capture showing the extra empty fragment causing issues.

  • TextWrittenExtraElementAppears-2.PNG - screen capture showing the second locations extra empty fragment causing issues.

  • TextWrittenExtraElementAppears-3.PNG - screen capture showing the second locations extra empty fragment causing issues. There is also a new line character in this string that is not being recognized.

Here is the code I am using to write the content.

// Procedure writing text fragments
public static void AddText(Page pdfPage, float x_indent, float y_indent, String content)
{
// Create text fragment
TextFragment textFragment = new TextFragment(content);
textFragment.Position = new Position(x_indent, y_indent);
textFragment.ZIndex = -1;

textFragment.TextState.FontSize = 9.5f;
textFragment.TextState.Font = FontRepository.FindFont("Courier");
textFragment.TextState.BackgroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.White);
textFragment.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Black);
textFragment.TextState.LineSpacing = 1f;
textFragment.IsInLineParagraph = false;

// Create TextBuilder object
TextBuilder textBuilder = new TextBuilder(pdfPage);

// Append the text fragment to the PDF page
textBuilder.AppendText(textFragment);

return;

}

Document dave = new Document(@“C:\Users\Desktop\ForAspose\BlankExample.pdf”);

AddText(dave.Pages[1], 386.467f, 585.221f, “EXPORT”);
AddText(dave.Pages[1], 386.467f, 575.122f, “CONTROL”);
AddText(dave.Pages[1], 386.467f, 565.023f, “COM”);
AddText(dave.Pages[1], 19.506f, 585.221f, “SUPPLIER CUSTOM MODULE LIST”);
AddText(dave.Pages[1], 19.506f, 57.813f, "(CONTINUED ON NEXT PAGE)\r\nSOMETHING COOL - SEE STANDARD NOTES FOR THOUGHTS ON DATA IN MY HEAD ");

// Save the new document
dave.Save(@“C:\Users\Desktop\ForAspose\TextWritten0.pdf”);

Thanks, Dave

Yes there are empty text fragments written to this document too. If you notice the lines are missing or different visibly that is an extra empty fragment being written.

If we could specify the ZIndex to push the text fragments to the lowest level that would resolve our problem too.

If you look at the BlankExample.pdf and the document you created. You will see where the issues are. I have highlighted them in the latest attachment to this post.

I think I know what the problem is. The extra artifacts I was seeing is caused by the TextFragment objects being drawn because i was setting a background color. Setting a background color to a TextFragment was creating a rectangle around the text, which was what I was observing in Adobe Acrobat.

The interestingly it looks like because of the page rotation the artifacts where left where they would exist prior to rotating. At least that’s what it looks like.

Hope that helps.
