Insert Image at Position

[masteriou]

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.

2) 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();<o:p></o:p>

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");

2) 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.

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

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:

@masteriou,

The issues you have found earlier (filed as WORDSNET-4977) have been fixed in this Aspose.Words for .NET 17.10 update and this Aspose.Words for Java 17.10 update.
