Thank you to Nigel (as usual) for coming up with something simple!
I added layers to my project and noticed it had the ability to Substitute one color with another, but I am not getting it work. I have attached a sample of the red color I want to remove from a form. Some scanners do the red drop out, however I was going to try to do this in software.
In this case, attached, I want to change the red on the form to white. There are no other colors on the form, just red.
I added the image as a layer. It displayed way down in the ieviewer1.image window, but that's another question.
I tried different versions of the code below, but it just doesn't pick the red correctly. I tried a single color also, using paint and getting the eye dropper to give me the RGB numbers.
Am I missing something?
Dim newLayer As Integer = IeViewer1.Image.LayersAdd("c:\batches\20211220-0001.tif", -1000, -1000)
Dim oldColor1 As HiComponents.IEvolution.IERGB
Dim oldColor2 As HiComponents.IEvolution.IERGB
Dim newColor As HiComponents.IEvolution.IERGB
oldColor1.r = 255
oldColor1.g = 0
oldColor1.b = 0
oldColor2.r = 160
oldColor2.g = 255
oldColor2.b = 255
newColor.r = 255
newColor.g = 255
newColor.b = 255
IeViewer1.Image.SelectColors(oldColor1, oldColor2, HiComponents.IEvolution.IEImage.SelOp.Add)
IeViewer1.Image.SetSelectedPixelsColor(newColor)
