What's wrong with Color.Black ?

Thats what i tried in the beginning. My image had a black background with a single white dot in the middle. I ran... If Bitmap.Getpixel = color.black then end ... and it would just run through without finding anything. I wonder if it is something to do with using a 24bbp image or something. Either way i solved it by using color.fromargb().

I also had problems directly comparing a known pixel color to predefined color even though their rgb and Argb values were the same.

For 'normal' and particularly for user defined colors (which are nameless) you can also use the argb value for comparison - it is only one integer instead of 3+1.

'-16777216 is black, -1 is white etc.
If myBitmap.GetPixel(xx, yy).ToArgb <> Color.Black.ToArgb  Then 

    MsgBox(xx & ", " & yy)
                
End If

For your second question try this link.
