VintaSoft Annotation .NET Plug-in Discussions

Hi Alex,

We like the ability of your components to save annotations as separate XMP files and have a business case where this would be very useful. I've got this working for single-image TIFF files using the following code:

//save files
for (int i = 0; i < imageViewer1.Images.Count; i++)    
{          
    //save each image as single file
    VintasoftImage img = imageViewer1.Images[i] as VintasoftImage;
    string newImageFileName = string.Format("{0}_{1}{2}", fileName, i.ToString().PadLeft(4, '0'), fileExt);
    if (encoder != null)
    {
        img.Save(newImageFileName, encoder);
     }
     else
     {
         img.Save(newImageFileName);
     }

     if (saveAnnotationsToolStripMenuItem.Checked)
     {
          //save annotations
          SaveAnnotations(i, ChangeFileExtension(newImageFileName, EXT_XMP));
     }
}   ...

private void SaveAnnotations(int imageIndex, string filePath)
{
    if (imageViewer1.Annotations[imageIndex].Count > 0)
    {
        XmlDocument doc = imageViewer1.Annotations[imageIndex].Save();
        doc.Save(filePath);
     }
}

The problem I have is that I can't get this working with multipage TIFF's. As far as I'm aware, I can only save multipage TIFFs by calling Save() on an ImageCollection. But when you do this, it ALWAYS saves the annotations (apparently within the TIFF file as I can't see a separate XMP file - is that correct?). What I want to do is:

1. Save all images in ThumbnailViewer as a Multipage TIFF without annotations
2. Save all images in ThumbnailViewer as a Multipage TIFF with separate XMP file
3. Save selected images in ThumbnailViewer as a Multipage TIFF without annotations
4. Save selected images in ThumbnailViewer as a Multipage TIFF with separate XMP file

Is this possible? If so, can you provide me with some example code for each of these requirements?

Thanks,

Ian

Hi Alex,

Thanks for the code, which allows me to save images without annotations. This answers requirements 1 and 3 in my original post. I don't see any code that allows you to choose whether to save the annotations in a separate XMP file though. This was essential for requirements 2 and 4 in my original post.
1. Save all images in ThumbnailViewer as a Multipage TIFF without annotations
2. Save all images in ThumbnailViewer as a Multipage TIFF with separate XMP file
3. Save selected images in ThumbnailViewer as a Multipage TIFF without annotations
4. Save selected images in ThumbnailViewer as a Multipage TIFF with separate XMP file The ability to save annotations as separate XMP files for each image (single or multipage TIFF) is looking increasingly important to our business model. I've got this working for non-multipage TIFF files ("all" and "selected" in thumbnailviewer) but not multipage ones (requirements 2 and 4). Is it possible to do this?

Thanks, Ian

Yes, that's correct.

I guess my question was: "is this possible?". Can I take it from your reply that it's not? I only started working with multipage TIFF's and your Annotation controls a few weeks ago so am learning what is and isn't possible as I go along. Is this a feature that could be added in future versions of your control or is it just not possible due to multipage TIFF file format?

Thanks,

Ian
