What steps will reproduce the problem?
1. Create RGB UnmanagedImage ->
Dim tmpImg As AForge.Imaging.UnmanagedImage =
AForge.Imaging.UnmanagedImage.FromManagedImage(foundImg)
2. Create channel image ->
Dim exChan As New AForge.Imaging.Filters.ExtractChannel(AForge.Imaging.RGB.R)
Dim redChan As AForge.Imaging.UnmanagedImage = exChan.Apply(tmpImg)
3. Insert the modified channel back to the original image ->
Dim replaceChan As New
AForge.Imaging.Filters.ReplaceChannel(AForge.Imaging.RGB.R, redChan)
replaceChan.ApplyInPlace(tmpImg) **** Throws the NULL Error
What is the expected output? What do you see instead?
I expect the ReplaceChannel to replace the designated channel. Instead, a Null
Reference is thrown. There is a work around to fix this (see below).
What version of the product are you using?
2.2.4
Please provide any additional information below.
Convert the target image and replacement channel to a System.Drawing.Bitmap
object before running the ReplaceChannel function. This runs with no problems.
