In OS X you can use NScolor Getcolor X Y to get the color of a specific pixel in a given image but this does not seem to be in the framework for the iPhone. Does anyone know how to do this?

Web applet to get pixel color

I know nothing about java, but I 'll learn if I need. But first, I need to know if a java web applet can do the goal I need:
A java web applet that can pass a specific pixel color on the browser windows to javascript. The coordinates of that pixel will stay outside the own applet borders.
I don't know if this is the right forum, so can you please help me in any way?
Thanks a lot.

A java web applet that can pass a specific pixel color on the browser windows to javascript. Yes this can be done, but as I recall it was somewhat of a pain. It will also be browser-specific. If you ask me the requirement is probably flawed.
The coordinates of that pixel will stay outside the own applet borders.Huh? So you need to sample a pixel? This post makes little sense. Post the exact use case. Way too vague.

Get pixel color in J2ME

hello,
if u know how to retrieve the pixel color of any specified coordinate pixel
,say (x,y) of a canvas please let me know ,i ll be thankfull to u.

you can try to create a new image and paint on that image.
Image img = new Image( yourcanvaswidth, yourcanvasheight );
yourcanvas.paint( img.getGraphics() );
int [] rgbs = new int[ yourcanvaswidth, * yourcanvasheight ];
img.getRGB( rgbs, 0, yourcanvaswidth, 0, 0, yourcanvaswidth, yourcanvasheight );
the rgbs holds RGB values of you canvas.
hope this will help

Please Help Get a Color from Pixel !!!!

Is anybody know how to get a Color from pixel.
My program is not Full Screen .
So i think Robot.getPixelColor() don't suitable.
Please Help me!

Robot.getPixelColor() will work fine, but the problem you will have is getting the mouse set to the correct location and getting your application to know where it is: you can do it with win32 calls and JNI. Here are a few that I have found helpful--they are in a VB format:
Public Const CLR_INVALID = &HFFFF 'not a valid pixel
Public Const MOUSE_MOVED = &H1
Public Const MOUSEEVENTF_ABSOLUTE = &H8000 ' absolute move
Public Const MOUSEEVENTF_LEFTDOWN = &H2 ' left button down
Public Const MOUSEEVENTF_LEFTUP = &H4 ' left button up
Public Const MOUSEEVENTF_RIGHTDOWN = &H8 ' right button down
Public Const MOUSEEVENTF_RIGHTUP = &H10 ' right button up
Public Const REQUEST_LEFT_CLICK = &H2D 'request left click "-"
Public Const REQUEST_RIGHT_CLICK = &H2B 'request right click "+"

Get the color of a pixel in an image

how can i do to get the color of a pixel in an image ???
Can anyone help me ?

Hi,
first of all you need to get the library to transfer your image to java.awt.image.BufferedImage object.
I know many such libraries. Its depends of what kind of image you have: jpeg, gif, png or other.
And when you get the BufferedImage of you picture using library, then you can get the color of any pixel in image using int BufferedImage.getRGB(int x, int y) as integer value.

Get the color of a pixel on the Stage

Is there a way to retrieve the color of a generic pixel on the screen using the mouse pointer inside the Stage of Flash Player? With the getPixel method of the BitmapData class you can get the color of a pixel only if the mouse is over a bitmap image, but what if I need the color a generic pixel on the screen?

this takes a snapshot of the pixel below the mouse:
function eventHandler(event:MouseEvent):void
     var bmd:BitmapData = new BitmapData(1, 1, false, 0x000000);
     var matrix:Matrix = new Matrix();
     matrix.translate(event.stageX, event.stageY);
     //can never remember which way translate works so it could be:
     //matrix.translate(-event.stageX, -event.stageY);
     bmd.draw(stage, matrix);
     var pixelColour:uint = bmd.getPixel(0, 0);

Getting the Color of a Pixel in a Image

Hi. I need to get the Color of the point in an Image (or ImageIcon). I've seen examples but they use BufferedImages.
Thanks, Bob

Here is a simple conversion for you:
BufferedImage bi = new BufferedImage(myImage, myImage.getWidth(null), myImage.getHeight(null), BufferedImage.TYPE_INT_RGB);
Graphics g = bi.getGraphics():
g.drawImage(myImage, 0, 0, null);If you are using ImageObserver objects, then replace null with the corresponding ImageObserver object in the BufferedImage and drawImage.

How to get pixel colour?

Is there any way to get pixel colour from specified point? Example: colour = image.getPixel(x, y);
J2ME/MIDP 1.0
Thanks!

{color:#800000}*I am happy to compare the two pixels of same image using this code in Java:*
{color}
Image ori, nw;
public void init()
{ ori = getImage(getDocumentBase(),"flower.jpg");
int pxl[]= new int [65536];
PixelGrabber pg = new PixelGrabber(ori,0,0,256,256,pxl,0,256);
// Image is stored into Array
try{ pg.grabPixels(); }
catch(InterruptedException e) {}
for(int i=0;i<65536;i++)
{ int p = pxl[i];
int ri = (0xff & (p>>16));
int gi = (0xff & (p>>8));
int bi = (0xff & p); // Take the RGB value of each pixel
for(int j=0;j<255;j++) // Chk. other similar pixel in color range of 0 to 255
int q = pxl[j];
int rj = (0xff & (q>>16));
int gj = (0xff & (q>>8));
int bj = (0xff & q);
if ( (ri==rj)&&(gi==gj)&&(bi==bj)&&(!(i==j)))
{ ri+=70;//if (ri<0) ri = 0;
gi+=70;//if (gi<0) gi = 0;
bi+=70;//if (bi<0) bi = 0;
pxl[i] = ( 0xff000000|ri<<16|gi<<8|bi); // Change value
else
pxl[i] = ( 0xff000000|ri<<16|gi<<8|bi);// Keep as it is

Pixel Color

I have an object of "Canvas" and I want to get the Color of the point where the user has clicked. How?

Fast and dirty: If you are not talking about an applet, you could use java.awt.Robot.
Better solution:
In Canvas the entire Canvas gets painted in the paint(Graphics) method. If you paint to an Image, not directly to the canvas, and paint that image to the Canvas to make it look the same, then you can find the color of any pixel by inspecting the Image. See the java.awt.PixelGrabber class on how to get the pixels of an image.

Get pixel vi picture control

Can i get a pixel color value without converting the picture data to an array?
Seems an unneccesary step in my opinion because internally the array data is available
anyway.
Neither the standard palette nor the vi.lib picture vis seems to contain procedures to read pixel values.

If you are using MS Windows, and the image is displaying on a front panel, there is a Windows API: GetPixel (https://msdn.microsoft.com/en-us/library/dd144909(v=vs.85).aspx) for that.

Hi,
several html tags have the attribute bgcolor, like
<body bgcolor="red"> or <body bgcolor="RRGGBB"> where RR, GG, BB is an hexadecimal value according to RGB color palette.
you can also work with CSS and in this case you affect the attribute style, which is also available in several tags:
document.body.style.backgroundColor="#EEEEEE"

The app icons I have on the iPad have just come up blank with the app name under it. How do I get the colorful icons to appear? The apps do work though

The Ipad icons are all just a grey box. How do I get the colorful icons?

First thing to try is a reboot of your iPad. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider until the Apple logo appears. Let go of the buttons and let the iPad restart. See if that fixes your problem.
