How can I get the color of a pixel at the location of the cursor? I know how to get the mouses position using MousePosition but I can not figure out how to get the pixel color at that location.

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 2 Repliesi am using an unbound datagridview so i can dynamiclly add rows. all that is working fine. but the grid is not is the location i have coded.. i am using the defualt form as a base then coding the unbound stuff in.. should i just create a blank class file and do everything? the only problem i am having is the grid must bees in the correct location according to the pixel point that i have given it. Right now it is placing the grid at point (0,0) no matter what point is entered on the line for location. so what am i missing??????

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
View 3 RepliesIn 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 13 Replies1. Is there either a program or a way of using vb.net where I can load an image and get a reading of every hexadecimal value for every pixel location in the image? Quick example, sometimes, I'll load an image into Microsoft paint and I try to determine which colors are being used in certain locations of the image but all I can do is guess.
2. If it is possible (especially using vb.net), is there a way to build an image by manually coding hexadecimal values for every pixel location, then, saving the image? The thought here is that I can build my graphic and then try different color schemes until I'm happy with its presentation.
I am writing a program in VB 2010. My computer is an E Machines dual processor Intel Celeron running at 1.8 gb/sec with 2 GB of RAM. I have a 1680 X 1050 display and the graphics driver in the computer is fully capable of utilizing this display. I am running Vista Home Edition.
The purpose of the program is to analyze a large number of infrared and visible light images from the geostationary satellites GOES East and West. Note: These images are TIFF and range in size from 400 KB to 70 MB. The pixels are either 8 bit or 10 bit depending on the image type.
The program allows the user to select a series of images from a file folder. These images are then displayed in a picturebox. A map covering the same area is also available to the user. The user may then move the cursor, via the mouse, to a selected location on either the map or in a picture. With a left click that location in terms of image coordinates is used to compute the geographic coordinates of the selected location. These coordinates are then displayed for verification purposes. So far, all of this works properly.
The next thing I need to do is to determine the brightness value of selected pixels in the displayed image. Because brightness is related to temperature this permits a detailed examination of cloud temperature and density in each image. By making this measurement at several different wavelengths (provided by images taken at different wavelengths) the program will then compute the atmospheric extinction factor at each selected wavelength and from that derive the atmospheric transparency function.
Here is where I have run into problems. I cannot find a way to extract the pixel value from the selected X, Y values input either by cursor position or by direct entry. I have tried the various approaches described in the documentation but I either get errors or a pixel value that is unrelated to the image. The following is a section of code that I am currently trying.

i have a chart of images.. and i want to load individual images into picturebox from that chart..chart = big image, eg alphabet chart. (yes i am creating a game for my small nephew.. pictures and alphabet) now, i want to show different pieces of images into picture box. like the A box, b Box etc one option is to cut the chart into pieces, save each piece with different filename and load individual filename into picturebox.but i saw somewhere that we can use pixel location to load images into picturebox..as i recall it required two pixel location, 1 was upper left and other was lower right.. and passing that pixel locations would load the rectangular image between those pixel locations into picturebox?

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.

View 3 RepliesI 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).

View 2 RepliesI've recently been working on some VB.NET programs, grab the value of the color of a pixel on my screen(Out of my WIN32 Application).
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.
What I want to do is get the color of a position on the screen. I'd rather not capture the whole screen if I don't have to, just one pixel's color.

I should be able program the rest of the program around it, I just need the detection part. That is where I am stumped.
