Insert Image at Position

Aspose.Words Product Family

Hi there!

I have the following two problems to solve:

  1. How do I insert a picture at a specified position relative to the edge ot the page?

This is the code I use (VB6 with COM-Interop)

oDocumentBuilder.MoveToHeaderFooter HeaderFooterType_HeaderFirst
With oShape
.RelativeHorizontalPosition = RelativeHorizontalPosition_Page
.RelativeVerticalPosition = RelativeVerticalPosition_Page
.VerticalAlignment = VerticalAlignment_Top
.HorizontalAlignment = HorizontalAlignment_Left
.Left = 0
.Top = 0
.AnchorLocked = False
.WrapSide = WrapSide_Both
.WrapType = WrapType_None
End With

When I ran this code I expected the image to be in the top left corner of the page (left=0, top=0), but it was inserted at the left/top margin of the header.

  1. I have to dynamically insert one or more images on one or more pages of the document. I have not found any method to use DocumentBuilder.MoveTo to go to a specified page…have I overloooked something? I read about the method GetPages() but could not find any reference to this function so far…

Best regards,
Michael

Hi Michael,

Thanks for your inquiry.

  1. You can insert a floating image at the top left corner of first page by using the following code snippet:
DocumentBuilder builder = new DocumentBuilder();
PageSetup ps = builder.PageSetup;
Shape shape = builder.InsertImage(@"C:\Temp\Aspose.Words.png");
shape.WrapType = WrapType.None;
shape.Left = 0 - ps.LeftMargin;
shape.Top = 0 - ps.TopMargin;
builder.Document.Save(@"C:\Temp\out.docx");
  1. I am afraid, there is no way to move cursor to the beginning of a Page; however, you can move the cursor to the first Paragraph in a particular Page and then make that Paragraph as an anchor point for your image. Here is how you can achieve this:
Document doc = new Document(@"C:\Temp\in.docx");
LayoutCollector collector = new LayoutCollector(doc);
Paragraph anchorPara = null;
NodeCollection paragraphs = doc.GetChildNodes(NodeType.Paragraph, true);
foreach(Paragraph para in paragraphs)
{
    if (collector.GetStartPageIndex(para) == 2)
    {
        anchorPara = para;
        break;
    }
}
DocumentBuilder builder = new DocumentBuilder(doc);
PageSetup ps = builder.PageSetup;
builder.MoveToParagraph(paragraphs.IndexOf(anchorPara), 0);
Shape shape = builder.InsertImage(@"C:\Temp\Aspose.Words.png");
shape.WrapType = WrapType.None;
shape.Left = 0 - ps.LeftMargin;
shape.Top = 0 - ps.TopMargin;
builder.Document.Save(@"C:\Temp\out.docx");

I hope, this helps.

Best regards,

Hi Awais,

thank you for your reply. The first problem is solved to my full satisfaction and as for the second problem I only have one more question: How do I instantiate the LayoutCollector-object in COM-Interop?

As far as I can tell, there is no creatable LayoutCollector object.

I can do this:

Dim oDocumentBuilder As New Aspose_Words.DocumentBuilder

But I can’t do that:

Dim oLayoutCollector As New Aspose_Words.LayoutCollector

Thank you in advance
Michael

Hi Michael,

Thanks for your inquiry. Currently, Aspose.Words defines four publicly creatable COM objects i.e. ComHelper, Document, DocumentBuilder and License. To access other classes/methods available in Aspose.Words API, you must have to create wrapper/helper classes. However, we will consider making all public API accessible from COM and scripting languages in future. Your request has been linked to the appropriate issue (WORDSNET-4977) in our issue tracking system and you will be notified as soon as it is resolved. Sorry for the inconvenience.

Edit: Please also visit the following link to learn how to use Aspose.Words for .NET via COM Interop:
