Picture Into Picturebox Based On Pixel Location?
Sep 30, 2009
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 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 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??????

1. 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'm trying to copy a picture from one location and paste it into another location however VB throws out the following error
Exception from HRESULT: 0x800A0046 (CTL_E_PERMISSIONDENIED)
both locations are on my local computer. So not sure what is causing the problem.
Here's the code
Module CPASU_SPC

I am looking for some information on getting the colour of each pixel in a picture. The ide is to get the colour and then have my program draw a line along that colour itself. For example. If i have a black square on a white background, I want the software to be able the draw lines on the four edges of the black square, Is this possible?

I 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

I'm loading a picture into a picturebox. How can I set the pixel width to a fixed number, ex 300?
The whole picture must fit the picturebox, even if the original resolution is higher.
Dim bmp As New Bitmap("c:Test.bmp")
bmp.SetResolution(300, 50)
PictureBox2.Image = bmp

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.
