Since we have customer using this kind of document, We might not know how they created the document.
Is there a way we can fix this kind of issue and can we generate image?
p.s: somehow I am not able to download the docx.
plus I am getting an exception

@m.darshan.shah Unfortunately, there is no way to keep the position of the image inside the form, and this is not a general solution for that. The only way is to put all the content inside the blue shape and try to change the position of the paragraphs:
if (currentNode is InlineStory || currentNode is Story)
{
CompositeNode composite = (CompositeNode)currentNode;
NodeCollection compositeNodes = composite.GetChildNodes(NodeType.Any, false);
if (compositeNodes.Count == 1 && compositeNodes[0].GetText().Trim().Equals(string.Empty))
return;
foreach (Node childNode in composite.GetChildNodes(NodeType.Any, false))
{
if (childNode == null) continue;
Paragraph shapeParagraph = shape.FirstParagraph;
if (shapeParagraph != null && shapeParagraph.FirstChild is Shape)
{
Shape childShape = shapeParagraph.FirstChild as Shape;
childShape.AppendChild(childNode.Clone(true));
}
else
shape.AppendChild(childNode.Clone(true));
}
}
or try to create a table inside the shape and put the form in the text in the cells. But this solution is only for one case with such forms.
@m.darshan.shah You are using Aspose.Words without a license, so the resulting document has an image inside the header, which is causing this problem. Please check the license if you have one, or you can get a temporary license for your tests. Please check Temporary License - Purchase - aspose.com
@m.darshan.shah You can try using the following simple code to convert headers/footers to image:
Document doc = new Document("C:\\Temp\\in.docx");
int sectIndex = 0;
foreach (Section s in doc.Sections)
{
foreach (HeaderFooter hf in s.HeadersFooters)
{
// Create a temporary document for rendering header content.
Document tmp = (Document)doc.Clone(false);
tmp.Sections.Add(tmp.ImportNode(hf.ParentSection, false, ImportFormatMode.UseDestinationStyles));
tmp.FirstSection.AppendChild(new Body(tmp));
// Copy content of the header to the temporary section.
foreach (Node n in hf.GetChildNodes(NodeType.Any, false))
tmp.FirstSection.Body.AppendChild(tmp.ImportNode(n, true, ImportFormatMode.UseDestinationStyles));
// Remove top and bottom margins.
tmp.FirstSection.PageSetup.TopMargin = 0;
tmp.FirstSection.PageSetup.BottomMargin = 0;
// Use LayoutEnumerator to calculate the bottom edge fo visible content.
LayoutEnumerator enumerator = new LayoutEnumerator(tmp);
RectangleF rect = RectangleF.Empty;
rect = CalculateVisibleRect(enumerator, rect);
tmp.FirstSection.PageSetup.PageHeight = rect.Height;
Console.WriteLine(rect.Height);
tmp.UpdatePageLayout();
tmp.Save($@"C:\Temp\hf_{sectIndex}_{hf.HeaderFooterType}.png");
}
sectIndex++;
}
private static RectangleF CalculateVisibleRect(LayoutEnumerator enumerator, RectangleF rect)
{
RectangleF result = rect;
do
{
if (enumerator.MoveFirstChild())
{
if (enumerator.Type == LayoutEntityType.Line || enumerator.Type == LayoutEntityType.Span)
result = result.IsEmpty ? enumerator.Rectangle : RectangleF.Union(result, enumerator.Rectangle);
result = CalculateVisibleRect(enumerator, result);
enumerator.MoveParent();
}
} while (enumerator.MoveNext());
return result;
}
Hi @alexey.noskov , that’s great. its working fine. but its creating the big image with white space,
is there a way I can create just header content and footer content ?
@m.darshan.shah I cannot reproduce the problem. Most likely you are using Aspose.Words in evaluation more and size of watermark is included into the calculation.
