Add annotations programmatically without viewer on multiple pages

Hi James,

How to add then burn annotations for multi-page document? Each page has its own annotations. For example, page no stamp. I have used the code in your link with one page image for a while. But I can't figure out for muti-page. Someone said that requires one AnnContainer for each page.

Our moderator has split your post to a new thread.

The main idea is to loop on all image pages, and on each page load the related annotation file then burn it to the image.
I have modified the project to load Multipage tiff and burn the same annotation file on all pages.
In your case, you may need to change the annotation file for each page since you said each page has its own annotation.

Thanks for the code. I can use it as my last resort. What I am looking for also is the ability to be able adjust stamp position for each page. so Add and Burn will be seperate operation. Is that doable? Thanks!

I realized my 2nd post is deviating from the subject in terms of "Without viewer". To be able to adjust annotation position by user, viewer has to be used. I will rephrase my question. Can this be done? Showing multi-page image on RasterImage viewer, then let user add text stamp on each page, user can adjust the stamp content and position for each page. once user is happy with all stamps on all pages, user will burn the stamps into the images. I hope this is clear. Thanks.

I am attaching a small C# 2010 project that shows how you can load\view a multipage TIFF image, draw text annotations on each page, burn these objects and then save the result to a separate file.

Thanks!! I am getting close with your code. But I am not familar with AnnAutomatiom. How to add a Text stamp once the button "Draw Text" is clicked? With your code, user has to click where stamp is needed to be added. I have a AnnTextObject defined already with position and text etc. Can it be added once "Draw Text" is clicked?

I modified the project so that the user can draw the annotation text object directly after clicking the "Draw Text" button.

Hi Maen, Sorry to bug you even more. Is it possible to add page no stamp for all pages when "Draw Text" button is clicked only once? I guess I can combine code of Draw Text, Click Next then Draw Text, click Next, etc.. But I am not sure if that is going work or that is ideal way.

You need to change the code of the "Draw Text" button as follows:
+---------------+
private void button1_Click(object sender, EventArgs e)
{
for (int i = 1; i <= rasterImageViewer1.Image.PageCount; i++)
{
rasterImageViewer1.Image.Page = i;

if (annAuto1.Container.Objects.Count > 0)
annAuto1.Container.Objects.Clear();

AnnTextObject TextObject = new AnnTextObject();
TextObject.Pen = new AnnPen(Color.Red, new AnnLength(3));
TextObject.TextColor = Color.White;
TextObject.Text = "Page:" + rasterImageViewer1.Image.Page.ToString();
TextObject.Brush = null;
TextObject.Font = new AnnFont("Arial", new AnnLength(10, AnnUnit.Point), FontStyle.Regular);
TextObject.EdgeMargin = AnnLength.Empty;
TextObject.Alignment = StringAlignment.Center;
TextObject.LineAlignment = StringAlignment.Center;
TextObject.TextRotate = AnnTextRotate.Rotate0;
TextObject.Bounds = new AnnRectangle(rasterImageViewer1.Image.Width / 2, rasterImageViewer1.Image.Height - 100, 90, 90, AnnUnit.Pixel);

annAuto1.Container.Objects.Add(TextObject);

SaveAnn(sender, e);

rasterImageViewer1.Refresh();
}         
}
+---------------+

Thanks for help! I used your code and then changed to use one memorystream per page. That worked well for my purpose.
