View 7 RepliesI'm trying to figure out how I would find the color of a pixle.
Say I wanted to find RGB(255, 255, 0) and get the X, Y, position of it, how would I do that?
I was thinking of a loop with BMP.GetPixel, but I wouldn't know how to check. It's not compatable with RGB.[code]...

View 1 RepliesHow can I find out the pixel colour of a certain point on a web browser. For instance,WebBrowser1.getPixelColor(0,0) would get the rgb colour value of pixel 0, 0.It doesn't have to be rgb it might be hsl or whatever.The web browser is showing a local web page that is hosted on a network. If there is an error then the screen goes all grey. What I want to do is, if this does happen, display an alert message like - "An error has occurred

I was trying to use GetPixel(ByVal hDC As IntPtr, ByVal x As Integer, ByVal y As Integer) As Integer, but I can't figure out how to get the handle to the screen.

I have drawn a grid in vb2008 so that each rectangle represents a 15 min period of a day. Time slots are shown by filling in the grid in different colours using the draw rectangle method. No problem so far. Now I want to discover the colour of any given part of the grid to prevent an overdraw.

2. How can I find the color of a specified pixel?
Is here quick way to find pixel color = 0 in rectangle (0,0,10,10)?For example auto it has PixelSearch ( left, top, right, bottom, color [, shade-variation [, step [, hwnd]]] )Is here quick way to find pixel color = 0 in rectangle (0,0,10,10)?

View 2 RepliesHow do i find the cursor coordinates on the screen in VB 2005 code?
"label1.Text = e.Location.X" Only gives you the coordinates in the program window itself, i want it to be displayed in a label/textbox in relation to the whole screen.

View 6 RepliesI have a JPEG picture from my digital camera and I want to find the color of a given pixel, say x=10, y=10. How would I go about doing that? I have searched around on the form but nothing is working. I have loaded the picture into a picture box but dont know where to go from there. Also is it possable for it to give me a number corrosponding to each color instead of 3 numbers, one for red, one for green, and one for blue. I am eventually going to be using this to scan through many
View 18 Repliesis there a way of getting the screen coordinates of individual cells on an open Excel sheet, what I want to ultimately do is pass in a cell range say, "A5" into a function and watch the mouse cursor move slowly to that cell. I know this might seem a weird request. I already have a mouse move function but that accepts the x/y coords in pixel terms where excel using .TOP and .LEFT give an entirely different format?
View 1 RepliesI 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?
View 13 RepliesI'm trying to work up a "Pacman" like game. I used multiple (Blue) RectangleShapes to draw a maze on Form1 and added a Timer and KeyPress event to show motion of the Picturebox ("PacmanImage"). The "Pacman" image changes depending on the direction it's travelling (also opens/closes mouth). Up/Down/Left/Right (and closed mouth) images are stored in imagelist1.
The maze has been set up with just enough clearance for the Pacman to fit between the walls. How can I check for any part of a Blue wall (RectangleShape) in the path of the Pacman? - I was thinking to take the position of the PacmanImage Picturebox and check (depending on the direction of travel) for the existence of a blue color in the appropriate rectangle on that leading edge. Ie: left travel would look at a rectangle defined as (x-1,y) to (x-1,y+25) and try to find the color blue where x/y are the top left of PacmanImage and it's image size is 25x25. Not sure how to do all this, but I think it's the right idea...
The ImageList has index/picture: 2/PacDown, 3/PacLeft, 4/PacMid, 5/PacRight, 6/PacUp (Indexes 0/1 are used for two additional pics not used for the motion of the Pac).
Code So Far:
Public Class Form1
Dim LeftRight As Integer = 180
Dim UpDown As Integer = 103
Dim Increment1 As Integer = 5

how can i get the actual pixel coordinates, in the pb_mousemove event, from an image with sizemode stretched or centered or zoomed?
the e.location property returns the location in the picturebox, but i need to compensate for scale + the left + top offset of the image.
i want to locate specific coloured pixel on whole screen (if i set it to red then it should point cursor on the first red pixel that was found on screen)i managed to get cursor coordinates and pixel color of place where cursor is pointing, but i cant figure this out.

In either of these (preferably Vb6), is it possible to replace a specific pixel color with a defined color? For example, if i scan my screen for 100,200,150, is there a way i can replace every instance of that with a specific color?
View 4 Repliesit is designed to be able to interact with foreground windows and display certain bits of information as each foreground window is displayed. The foreground window will most of the time NOT be a windows form so this makes things that bit more trickier for me. The program below doesn't produce any errors but the problem arises when I try and get the X, Y coordinates of the cursor, at the moment when ever the cursor is moved around I get a very long number as the X and nothing returned for my Y. I find I can set the X,Y coordinates to anywhere on the screen, can also get the foreground forms title,it's RECT coordinates but need to get the cursor info correctly.

I might sound somewhat 'newbish', this is my first post on VB. I was wondering if anyone knew how to convert screen coordinates so it works on other screens as well, I made 2 programs, one to get 'my' MOUSE coordinates and the other to click where I want it to click.

I've read all of the examples for getpixel using bitmaps. I'm not using bitmaps.
I'm drawing simple shapes to forms and pictureboxes.
I need an example of how to get the color of a pixel (x,y) for use with forms and controls.
how to get the color of a pixel (x,y) on the screen would be helpfull to.
