Insert hyperlink from picture to another url using mergeimagefieldeventargs

[jon.lumpkin]

Hi,

I am currently inserting an image into a document, using a mailmerge and the MergeImageFieldEventArgs with a handler. I do this because the image is coming from the database as a blob, I need to do some resizing, etc.

I have a new feature where we want the user to be able to click on this image, and it link to another page (in this case, another page that will show a full res version of the image).

I am currently using e.ImageStream to set the image contents.

How can I then create a link around this image that takes the user to another URL?

Thanks for your inquiry. You should set HRef property of the shape. Please follow the link to learn more:

So, I suppose, to achieve this you will be compelled to use DocumentBulder.InsertImage method to insert pictures.

Best regards.

Yeah, this is what I found earlier. It looks like I am going to have to rewrite this part of my code.

This particular document only has this one image, so no need to even do a merge or have that handler. But Im assuming if you did have a handler, with multiple images, you would just have to do the documentbuilder.insertimage in the handler as well?

Thanks for your request. Yes, in case of using mail merge you can try using FieldMergingCallback, please see the following code:

// Open template

Document doc = new Document("in.doc");

// Prepare dummy data for mail merge

string[] names = { "myImg" };

object[] values = { File.ReadAllBytes("image.jpg") };

// Add merge image field event handler

doc.MailMerge.FieldMergingCallback = new MergeImageFieldHrefImage();

// Execute mail merge

doc.MailMerge.Execute(names, values);

// Save output document

doc.Save("out.doc");

private class MergeImageFieldHrefImage: IFieldMergingCallback

{

void IFieldMergingCallback.FieldMerging(FieldMergingArgs args)

{

// Do nothing.

}

void IFieldMergingCallback.ImageFieldMerging(ImageFieldMergingArgs e)

{

// Create DocuemntBuilder and move its cursor to the mergefield

DocumentBuilder builder = new DocumentBuilder(e.Document);

builder.MoveToField(e.Field, true);

// Insert image and specify its size

Shape shape = builder.InsertImage((byte[])e.FieldValue);

shape.HRef = "http://www.aspose.com/Community/Forums/75/ShowForum.aspx";

shape.ScreenTip = "Aspose.Words Support Forums";

e.Field.Remove();

}

}

Best regards,

I ended up just redoing my code to not use the handler since I didn’t really need it in this particular report. This worked just like needed. Only thing I noticed is that I set the ‘ScreenTip’ to something, and I don’t see it show up in IE (I assumed it was the alt text for the image).

Thanks for your inquiry. ScreenTip property defines the text displayed when the mouse pointer moves over the shape in MS Word. And as I can see it works as expected in MS Word.

Best regards,
