Sampling the color of a pixel

I have a very simple question: Is it possible for applescript to sample the color of a specific pixel on my screen and store it in a variable? (or three variables as the case may be)
Thanks

I knew I saw something like this earlier, but it took me a little while to find it.
There is a scripting addition called XTools that lets you move the mouse from AppleScript - it is available at http://lestang.org/osax/XTool/XTool-2.0.dmg.tgz . With XTools installed, it is a simple matter to move the mouse to where you want, then tell DigitalColor Meter to copy the color to the clipboard (it isn't scriptable, but you can use keystrokes):
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #FFEE80;
overflow: auto;"
title="this text can be pasted into the Script Editor">
move mouse {500, 500} -- requires XTool OSAX
tell application "DigitalColor Meter"
activate
tell application "System Events" to keystroke "c" using {shift down, command down}
end tell
log (get the clipboard)
</pre>

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);

Setting the color of individual pixels in a bufferedimage

i am trying to set the color of each pixel in a loop as follows:-
BufferedImage bi=new BufferedImage(w,h,BufferedImage.TYPE-INT_RGB);
for(int j=0;j<h;j++){
for(int i=0;i<w;i++){
pixel=translate(i,j);
clr=findcolor(pixel);
if(clr==-1){
bi.setRGB(i,j,0);
else
bi.setRGB(i,j,clr);
findcolor() function just returns an int, so how do take this integer value and set the appropriate color?
when i execute this code,in the PaintComponent method of a JPanel class, my entire panel becomes black, this is not because of my first "if" condition.i checked the return value of my findcolor function.
However if i multiply the color value by a large number like 10000, then i get a few colors only(black,blue, green)
So please let me know how i can get all colors, without having to multiply the value.

What do the translate and findcolor methods do?

A simple question involving the color of a pixel?

I'm just wondering, I'm using a BufferedImage to load an image and retrieve the pixels by their location in an image. I looked through the APIs, but I can't seem to figure out how to find the shade of each pixel. I understand that each color has a range within the possibilities of the int returned in the method getRGB(). Does the range denote the shade? Or does the alpha value perhaps? I'm not sure. Any help would be appreciated. Thanks!

What do you mean by the "shade"? Do you mean hue?
You might want to look at the HSBtoRGB and RGBtoHSB methods. HSB is a way to describe colors via their hue, saturation, and brightness.
The alpha value indicates the transparency of the pixel.
Just out of curiosity, what are you doing?

The color of a pixel in Graphics

Hi... does anyone know how to get the Color of a specific pixel in a Graphics object??
For example:
public void paint(Graphics g) {
// Something like this would be great! (but it doesn't exist)
Color c = g.getColor(10,10);
/* etc... */
}Does anyone know something about it?

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 read the color of pixels on the desktop?

Hi All!
how is it possible to read the color of certain pixels on the screen? This is not withing any GUI or graphical java application. That is, the java program is supposed to be invisible to the user, run in the background and have access to the color information on the desktop. I have no idea if this possible at all and don't know how to search for it. With which functions/APIs is it possible?
Would be very thankful for any hints!!
Alex.

Thanks a lot! this is exactly what I was looking for. Moreover, this class has other good things like how to control mouse, which I was also looking for.
So, you answered two my questions : )
Many thanks agian!!

Why does the color of a smart object differ from the actual shape that it was made from?

I have some smart objects in a file that I've been working on. For example, I have a simple replay button shape. But, for some reason the color of the smart object differs from the actual color of the shape. In other words, if I sample the color of the smart object it has a hex code of ae7f2c (image1). But if I double click into the smart object to see the actual shape color the hex code is correct: a37e2c (image 2). It's a very slight shift, but causing me to go off brand colors for a client that I am working for. Any idea what could be causing this? Thanks for your help.

How did you create this smart object? Paste from Illustrator. A shape layer from Photoshop?
If from Illustrator turn off color management, copy and repaste into Photoshop.

Photoshop CS5 colorpicker sampling lighter color

When I try to edit the color of a shape layer by opening the color dialogue box of the shape layer, the color that is picked up is a lighter color than the color I clicked on.
The eyedropper is set to point sample and all layers. This problem does not occur if I open the color dialogue box that is part of the toolbar.

A screenshot showing everything at the moment just after you sample the color would be good as well.
Keep in mind that adjustment layers above the layer will affect how it looks on the screen, but when you're editing the color of the layer itself it's going to show you the actual color of the layer.

Find color of specific pixels

I'm working with grayscale images and I need to find average darkness of specific regions. The areas are all perfectly circular.
I can't figure out how to determine the color of specific pixels in an image. Does anyone know of a way? I need to process millions of pixels so I would prefer something that can do this relatively quickly. The images are all grayscale, so I only really need to know the darkness of the pixel.
I don't suppose there is any built-in way of doing this that would be more efficient than my computing the average manually?

Ok, it seems that I can use a BufferedImage to acquire the colors of specific pixels. I found a couple methords that seem relavent:
public int getRGB(int x, int y)
public int[] getRGB(int startX, int startY, int w, int h, int[] rgbArray, int offset, int scansize)
The first is pretty staight forward, but I am interested in performance, and the second sounds like it could be better.
I'm not sure about the meaning of the the scansize argument:
scansize - scanline stride for the rgbArray
Am I right in thinking that rgbArray is defined that the value in the first index (after offset) is the upper left corner, the next is the pixel directly to the right of it. When the index become equal to scanline, you are now on the next row of pixels below.
This doesn't make sense to me because it would defeat the purpose of having 'w' (the width).
Now, the other question is whether using the second methord will actually improve performance...I need circular regions, so using a rectangle will waste data. Would I be better off using getRGB(int x, int y)? How about creating a subclass of BufferedImage designed to extract the colors in a circular manner. Actually, is using a BufferedImage the best approach even?

When I add a photo filter to an image, I can't use the color sampler in the photo filter dialog box. It automatically selects white. What am I doing wrong?

Whenever I add a photo filter to an image, I can't use the sampler tool that automatically appears when you open the photo filter dialog box to manually select the color of your filter. Whenever I try to use it, it automatically selects white (#ffffff), no matter where I click in the image. Does anyone know what I'm doing wrong?
Thanks

When you add an adjustment layer, the layer mask is automatically active. You need to activate the pixel (image) layer by clicking on it in the Layers panel.

How to organize the sample color grid in the Color box?

Do you have any tips/tricks to keep the small squares of color in the Color menu organized? These are the color samples that you pull from the color bar at the top of the box and that you drag onto the grid for future reference. I have been willy nilly dragging squares of color onto that grid and it works fine for short term work but I cannot remember what square was for what if I have left that page and need to return to fix or change something. The only thing I can think of is to make a paper graph and notate on that hardcopy.
One thing that I have been doing is, for colors that are hard to distinguish, I load the tiny squares onto FOUR grid squares to make one bigger square of the sample color.
But..... does anyone have another way?

Hey Lorna,
After viewing the video Kyn pointed you to, you know
all about the Magnifying glass now, right? Let me
know if you need any clarification to answer your
question.
Ogawd I feel like an idiot now. I don't remember....... but I have the URL.

Color sample chart shows names and numbers but not the color sample

on our website we display multiple pages with a color sample chart.
The descriptions of this chart still displays but the color samples are not shown.
