[RESOLVED] [2005] Changing Colors in a Bitmap

[neef]

Is there an easy way to manipulate a bitmap image to change every pixel from one color to another? I have star images in a datagridview column that I want to change background color when highlighted.

Thanks!

you could write a small program that changes the colour of your star image using .setpixel

use 2 loops

Dim img As New Bitmap(filename)
 
 
for c = 0 to img.width
    for r = 0 to img.height
        if img.GetPixel(c, r) = ctype(color.fromargb(r,g,b), long) then
           img.SetPixel(c, r, Color.Blue)    
        end if
    next
next

then you can change images, in your selected event

That's good stuff and should take care of things fine.

Thanks so much!
