Header Picture Disappears When Replacing Bookmark Text

GemBox.Document
1

Hi,

I encountered an issue with a simple docx containing a header with two bookmarks (Bookmark1 and Bookmark2) and a picture.

When I replace the text of Bookmark1, the picture disappears.
However, this issue does not occur when replacing Bookmark2.

Here’s the code I’m using to replace the bookmark text:

document.Bookmarks["Bookmark1"].GetContent(false).LoadText("Bookmark1 replaced by this.");

To demonstrate the behavior, I’ve created a minimal example, which you can find here: GitHub - sengelps/gemboxHeaderBookmark

Hi Simon,

That is a floating Picture element anchored inside the “Bookmark1” bookmark.
In other words, see this:

DocumentModel document = DocumentModel.Load("headerExample.docx");

var header = document.Sections[0].HeadersFooters[HeaderFooterType.HeaderDefault];
var paragraph = header.Blocks[0] as Paragraph;

foreach (var inline in paragraph.Inlines)
    Console.WriteLine(inline.ElementType);

The result is:

BookmarkStart
Picture
Run
BookmarkEnd

Another way you may notice that this Picture is inside the “Bookmark1” bookmark is to change its layout from floating to inline:

I hope this helps.

Hi Mario,

thanks for shedding light on this issue!
Your explanation was helpful in understanding the structure of the document.
When moving the picture’s object anchor, I can replace the bookmark text without losing the image.
