Interface And Graphics :: Rip Pixel Color Off Of The Background Image Picturebox ( The Level)?

Ive been working on creating a side scroller game, and the back color of my pictureboxes needs to go. when transparent, it shows through the program and onto whatever is active in your Windows os(usually Visual studios).

I am trying to rip pixel color off of the background image picturebox( the level), and replace parts of the character picture box that show transparency with the level art. there may be poor logic in my code?

Heres my code:

Dim newImage As Bitmap = New Bitmap(PictureBox1.Image)
Dim backImage As Bitmap = New Bitmap(PictureBox2.Image)
Dim ximg As Bitmap = New Bitmap(PictureBox3.Image)

[code]....

not the best idea, but all i get is one color for all the level pixels placed in the new image, which is odd. any poor logic you see in this code that could allow the newImage.setPixel not to be 1 color? when i breakpoint, it is recieving different colors from the backimage.getpixel, but only putting one shade on for setpixel somehow. im not going for an accurate color read from the background yet, just wondering why im getting 1 pixel color for the whole picturebox background when being changed.
