Pardon the interruption for which might be a stupid question or method for what I am try to do. I *think* I almost have it, however I could use a little help, especially if there is a better way to do this.
Essentially I just want to write a text string on an image within an image list. I can do the entire thing, but then I have to save it to a file to reload it into the imagelist. There's got to be a better way, so I was doing it with the Microsoft Drawing library. Here's the code snippet:
Dim img As New HiComponents.IEvolution.IEImage
img = multiScan.ImageList.GetImage(0)
'multiScan.ImageList.CopyTo(multiScan.ImageList.ImageCount - 1, img)
Dim original As System.Drawing.Bitmap = img.CreateBitmap()
Dim newImage = New Bitmap(img.Width, img.Height)
Dim gr = Graphics.FromImage(newImage)
Dim pnt As New Rectangle
'Dim fnt As New Font("Free 3 of 9", 48, FontStyle.Regular)
Dim fnt As New Font("Courier New", 48, FontStyle.Regular)
gr.DrawImage(original, 0, 0)
gr.DrawString("2021012099998888", fnt, Brushes.Black, New RectangleF(20, 20, 1000, 100))
newImage.Save("C:\tmp\goodie.bmp")
I can save the bitmap as a BMP and load it back. My question is, how can I take the bitmap and load it back into the imagelist with the embossed/annotated image? Everything I've tried so far causes an exception.
Thanks in advance!

Hi
I don't think there is a more efficient way to draw text than you are using.
You could also use a text layer and merge it into the image, but it would be inefficient for this task:

Nigel, thank you for giving me that piece of info, the app would have crashed if I hadn't done the release.
Did you understand what I am trying to do? Put text (annotate) the image with a specific string that would be saved in on the TIFF bitmap.
I am having to call the Windows Drawing library, then save the bitmap as a file, load it back into IEvolution Imagelist. This seems like NOT the way to do it. Is there an easier way to do that all inside of IEvolution. I just really want to put at time/date stamp on an multipage TIFF and save it. I think I'm close, I just had to use the Windows framework. Is there another thread that references that?
Thanks in advance, this project is almost done!

Hi Brandon
You should call ReleaseImage after your changes:
https://www.imageen.com/ievolutionhelp/html/38fff9a0-2838-fb32-2a9a-d9f7e35023a8.htm
Enabling the saveChanges parameter.
You should then call multiScan.ImageList.UpdateImages or multiScan.Update
