I'm wondering if there is a method to access the progress of leadtool as it is loading an image?

I use RasterImageViewer to load and view my images in my C# projects.
But some images take a few seconds to load, and sometimes it makes it
look like my application has crashed. I was wondering if there is a
facility to inquire leadtools it's current progress in loading an image
so I can use that value in a separate thread to update the progress bar
in a separate window. Also does Leadtools already have a facility to create a progress bar as it loads an image?

We don't have a progress bar control, but you can use a number of other controls, such as a track bar or even a scroll bar.

Getting the progress during loading depends on the file format. For
most formats, you can use the LoadImage event. Here's a simple code
snippet that shows how to calculate the progress percentage (if the
image file format supports that):

Dim WithEvents LCodecs As New Leadtools.Codecs.RasterCodecs()

Private Sub LCodecs_LoadImage(ByVal sender As Object, ByVal e As
Leadtools.Codecs.CodecsLoadImageEventArgs) Handles LCodecs.LoadImage

Dim PagePercent as Integer = 100 * (e.Row+1) / e.Info.Height

End Sub
