Monochrome BMP

 

Hi all!

 

Anyone knows the way to transform any type of BMP picture (with colours) into a monochrome type picture ¿?

 

Thanks

edit with paint

save as Monochrome Bitmap

 

unless ur trying to do that within the program:

just use 2 bitmaps

1 colr and 1 mono. and then use the GDI+ to display the mono ontop of te color

There's another quite easy solution:

 

Dim source As New Bitmap("C:\myColoredImage.jpg")
Dim dest As New Bitmap(source.Width, source.Height)
Dim destGraph As Graphics = Graphics.FromImage(dest)
ControlPaint.DrawImageDisabled(destGraph, source, 0, 0, Color.Empty)
destGraph.Dispose()
dest.Save("C:\myGrayscaleImage.jpg")
