View 3 RepliesInterface And Graphics :: Rip Pixel Color Off Of The Background Image Picturebox ( The Level)?
Feb 27, 2009Ive 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.
Load A GIF File, And Start With The First Pixel And Check To See If That Pixel Color Is Closer To Black, Red, Green Or Yellow?
Jan 30, 2009I would like to load a GIF file, and start with the first pixel and check to see if that pixel color is closer to Black, Red, Green or Yellow, then take what ever color it closest matched to and output that color as a number, 0, 1, 2 or 3. So just for a small example a 5x4 GIF would be converted to something like this: 0112223322220111332?

Get Pixel Color Of Label?
Oct 8, 2009I am creating a custom tooltip label. My problem is auto resizing it (particularly height).The thing to note here is that the label i am using is an infragistics label, and i can have different fonts and formatting inside the label which means i cant just measure the text height based on the font because the label will contain multiple fonts.The only thing i can come up with is to make the label the height of the screen, and then perform a loop which scans the colour of each row of pixels starting from the bottom, decreasing the label height each time until it finds some pixels which <> the backcolor of the label (which would indicate that there is some text there).This is the only reliable way i can think of to make this happen, but im having trouble finding out just how exactly to get the color of the pixel at the given point.I did find one method of getting the pixel color, but the problem was that it when i requested it in the form_load it didnt return the right color because the screen wasn't painted (i guess).

I need this so I can make a little bot that automatically pushes buttons for a online game called "JamLegends"(http:jamlegends.com). Its kind of like Rock Band, and if I can grab the color, then I can simply used 'sendkeys' to press buttons to make the bot work.
Edit: This is for a project in school. We need to make something that will make a program that will make something easier to work with or use(In my case, JamLegends). I have nothing to work with, I've researched a bit but I found nothing that can grab pixel color values.

View 1 RepliesRead/Write Color Of A Pixel?
May 6, 2010This is my first Visual Basic application. I mainly do console applications in C++ and since working with pixels seems to be difficult in C++ I preferred to use VB 2005 for that. What I need to do is to read and save the colors of the pixels of a picturebox located on a form into an array. I then will manipulate the color values and create a new picture. I wonder if somebody could show me how to do that without asking me what my code is. I've struggled the whole day and so far I've realized that to draw a pixel you should draw an ellipsoid like:e.Graphics.DrawEllipse(Pens.Red, 70, 70, 1, 1)in the picturebox_paint procedure.What I need to learn is how to read the color values, and how to initiate creating the new picture by pressing a button (because I don't want the part for drawing a pixel be in the picture_box procedure.)
