New Post: Issue with MagickImage.Negate()

Can you please check if there's some memory allocation issue with .Negate() filter as I am having the following problem.

I load an image into MagickImage. I have 2 Picturebox - one always showing the original image, the 2nd showing altered image after filters. For speed concerns I simply clone the Original image to a Processed image, don't load the image again from the file.

After applying a .Negate() the Original image gets changed just like the Processed one. This happens only with Negate filter, many other filters I used work just fine. Also this doesn't happen if I don't clone the Original to the Processed image, but load the Processed image from the file again..

I don't know if this is issue with Negate filter, or I am doing something wrong...

Here's my code:

Class MyClass

Private OriginalImage As MagickImage
Private ProcessedImage As MagickImage

Private Sub Test()
        'load the original image
        OriginalImage = New MagickImage("image.jpg")

        ' display the original image
        PictureBox_Original_Image.Image = OriginalImage.ToBitmap
        
        ' clone the original image to the processed one
        ProcessedImage = OriginalImage.Clone
       
        ' do some filters
        ProcessedImage.Negate()

        ' show the processed image after the filters
        PictureBox_Trainer_Processed_Image.Image = ProcessedImage.ToBitmap

        ' redisplay the original again to show there's problem with the .Negate filter
        PictureBox_Trainer_Original_Image.Image = OriginalImage.ToBitmap
End Sub

End Class

Thanks in advance for your help!
