Get Pixel Color in VB.Net 2005 Picture Box

[JasonRox]

Hey!

Does anyone know how to get the "color" of a pixel in a picture box, in VB.Net 2005?

I want to encode things into an image, and then later pull the information out of the pixels.

You can get the color of the pixel at position (x, y) by
calling the 'Bitmap' objects's 'GetPixel' method.

So, what is that? Like this?

Systems.Bitmap.GetPixel()

 

[Greg Bernhardt]

pf_bitmap = New System.Drawing.Bitmap
pf_bitmap.GetPixel(1, 1)

 

[JasonRox]

pf_bitmap = New System.Drawing.Bitmap
pf_bitmap.GetPixel(1, 1)

Thank you!

I'm going to try it out right now.

Oh yeah, what kind of information will it give me? That's another thing.

I have another question.

Now, what is the code to get the pixel that you clicked on?

So, you have a Picture Box.

If you click on it, how can I get the pixel location of where that click was?

If you are in VB then you should have the "mousedown" callback for the picturebox.

I'll look into that.

My program will get better and better.
