Get colors from image
Is there any way to get the colors from an image in photoshop? Ideally, I would like a simple process to get a swatch collection from an existing image.
Thanks,
CFH
I don't know if this is the easiest way, but, change Mode to Indexed. Go to Mode>Color Table and Save the table with a new name. Then you should be able to load it in the Swatches palette from the flyout. Choose .act in the dropdown.

Hey people, I'm new to Illustrator and have a question. I want to use a color from an image that I put into Illustrator.
The exact things I did with the image are the following: copied it from Windows Photo Viewer into Illustrator, then put the 'cut out' effect on it, then copied it into a new Illustrator document that has a businesscard template and resized it fit the template's margins. Now I want to kind of 'enlengthen' the image by putting a square next to it. To make it look smooth, it has to have the same color as that side of the image of course. But that's my problem, I'm not able to select the color from the image and make a new color group with that specific color. The 'get color from selected artwork' button doensn't help much since I can't click it, for some reason the mouse turns into this 'can't click here' icon every time I move it on this button.
Any help would be greatly appreciated!
PS apologies for any unavoidable noobnessTo sample a color from a raster image, ShiftClick with the Eyedropper tool. (CS3)

I need a way to get the Color from a paint panel when the user clicks the mouse. I already have the mouse listener set up to return the co-ordinates within the paint panel.
Could you suggest a class and method I could use, to get the color value from the paint panel.
here's some of the code, so you know what i'm taking about
public void mouseClicked (MouseEvent e)
System.out.println("the co-ordinates are "+ e.getX()+" "+e.getY());
}There is no Image object there is only a paintPanel object.
Doesn't seem to be a constructor for an image object in the Image Class.
There must be an easier way of getting the pixel color for any given co-ordinates within the paintPanel object. -
Reading pixel color from Image?
Hello frnds,
I am making a project in which i have to upload Image, am trying to find color of each pixel in RGB format so that I can locate where my sprite begins in Image !!
But I am not able to do so.. do I have to use PixelGrabber to do that? or should i use RGBImageFilter..!! I am new to java so if u can tell me how to use them, then It would be grateful.
I want to scan whole image from left to right, Right to left, top to bottom and vice-versa. So that I can exactly tell at what pixel value sprite starts and ends.
Please help me out. any sort of help will be useful for my project..
Thanking you in advance.Image bufferImage;PixelGrabber pg1;

bufferImage = Toolkit.getDefaultToolkit().createImage(jpegData);

Hi,
Can someone please tell me how to get the bytes from an Image object in an applet. I need to send the data to php or asp script to save to image file on server. Preferably in jpeg format if thats possible. Thanks.what i need is to save an Image object to the server. I have written all the applet functionality in editing the image in various ways i just need to know how to get all the data and transform to jpeg data that can be sent from applet to a php script that simply writes the data it recieves to the disk. so far all ive been able to do is get short things like [B@4e2f0a to be written to the file on server. can someone please direct me as to waht i need to do and show me working code example or something. thanks alot.

I'm trying to get the binary pattern from an image and store it byte by byte, so i can manipulate it.
Any help on how i would go about doing this would be greatfully recieved.
Perhaps a url to some relevant material would be nice. Thought I'd come to the guys who know about this sort of thing.
Thanks
Frasertry {
int[] pixels = new int[width * height];
PixelGrabber pg = new PixelGrabber(img, 0, 0, width, height, pixels, 0, width);
pg.grabPixels();
return pixels;
} catch (InterruptedException ie) { return null; }This code is an example using a pixel grabber to retrieve an array of int values, each representing pixel data.
int values are 32 bit, but the pixel data should only encompass the first 8 bits of each int.
You can't cast the int to a byte because it will chop off the bits from the other end leaving you with a byte full of 0's and a black image.
To convert these ints to bytes you can use bitwise operators to chop off the leading 0 bits and then build a byte array with your image data. -

Best way of removing color from image
Hey Adobe Community,
I'm Aaron. I have this image here: https://www.dropbox.com/s/zjpjq5mf8t02pn9/chimera1-Recovered.jpg
What I'm trying to do is create an outline for a pattern, something like the hot dog in the pattern here: https://m1.behance.net/rendition/modules/59556275/disp/36d76e9e0f33274e8a75ea77fd69b731.jp g
Anyone know if this is possible and what is the best way of doing it? I'd like to keep the outline throughout the whole design of the chimera. Doesn't matter how tedious , I just need some ideas.I know of no good way to do this in Photoshop.
The quickest way I know is to place the original photo in Illustrator, reduce the opacity of it somewhat, and use the pen tool on another layer to draw what you want. Depending on the nature of the image, it can be tedious, but you don't mind that. :+)
Good luck. -
How do I transfer a color from one object to another without losing the gradient?
COLORING AN OBJECT AND SAVING THE GRADIENT
These are my notes.
x
Choose the EYEDROPPER tool.
x
Sample the color you want from an object in your image.
x
Double-click on the fill icon at the bottom of the tool panel.
This brings up the COLOR PICKER panel.
In that panel, you'll find the numeric value of the color you sampled.
I followed these instructions but when the COLOR PICKER panel came up, it didn't show the color it was suppose to show. The color I sampled with the eyedropper was a light blue with a gradient. I had a few different files up with the same image. One file brought up the color orange in the Color Picker panel. And another file brought up a total BLACK, with a numeric value of 0000! Can anyone tell me what's happening?My guess is the eyedropper tool is struggling. The best way and the one I use is to get color readings in Photoshop using its eyedropper tool. Write down the color percentages for each color you want from the image. Then, in Illustrator, I use the color palette to create new swatches using the percentage I wrote down from the actual image file. Those new swatches can be used ( or transferred to ) in the gradient palette. I have never used the eyedropper tool for getting color from anywhere in Illustrator. But, that's just me.

[CS2/CS3] - Getting color of stroke
I'm parsing graphical objects (rectangles, ...) and I want to be able to get color of stroke(fill color),
I use this code:
Utils()->GetFillRenderingUID(sourceFillRenderingUID, sourceGraphicStyleDescriptor);
to get sourceFillRenderingUID and now I use:
PMString sourceStrokeColor = Utils()->GetSwatchName(sourceSplineRef.GetDataBase(), sourceStrokeRenderingUID);
but this method returns me name of color only in case of base color (Black,...),
please how to get color CMYK or something similar to be able to compare 2 colors ? Thx, marxinI found out, that if I create a graphic object with defined swatc (f.e. C=100, M=0, Y=0, K=50), my code:<br/>
Utils<IGraphicAttributeUtils>()->GetStrokeRenderingUID(sourceStrokeRenderingUID, sourceGraphicStyleDescriptor);
PMString sourceStrokeColor = Utils<ISwatchUtils>()->GetSwatchName(sourceSplineRef.GetDataBase(), sourceStrokeRenderingUID);
my code correctlly gets "C=100, M=0, Y=0, K=50" as a name of strokeColor. But If I create user defined solid color (which is not a swatch profile), my code gets "" as a Name. I read in guide that solid color f.e. will create a local swatch profile, but I am not able to get the color from UID.
Please could anyone help me how to get color from stroke and local swatch ?

I have been using lv_vfw.llb VI's for grabbing images from a CREATIVE WEB CAM ,i am able to get color images in the continues shot but when i try to snap a color image which i need for my processing i get only a monocrome image ,i have been trying to play around with the RGB weightings but i am unable to get a color iamge,it shall be of great help if you could help me in doing this as it is urgent for me.Thanks for your help.
vicky,
I am unfamiliar with the lv_vfw.llb, and have not used it before. However, I noticed that you stated that you are able to grab in color, just not snap in color. If this is the case, why not just perform a grab and then extract a single buffer from this grabbed data, which would likely be in color? This seems like a possible solution to the issue that you are seeing.
Other than that, I really don't know enough about the lv_vfw.llb to be of much help on this issue. Hopefully another member of this forum will be able to assist you with this software.

How to get a .tif image with n different colors?
Hi..i want to know how can i get a .tif image colored by some colors. I want to do something like this:
if(tifImage.pixel < 0.1) {
tifImage.pixel = yellow;
else if( 0.1 <= tifImage.pixel && tifImage.pixel <0.5){
tifImage.pixel = red;
up to n colors.
I prove the next code, but it is not getting the colors i want.
public void generateImage(BufferedImage bi,double alto,double medio,String output){
int width = bi.getWidth(); // Dimensions of the image
int height = bi.getHeight();
// Some constant colors (as arrays of integers).
int[] red = {255, 0, 0};
int[] green = { 0,255, 0};
//int[] blue = { 0, 0,255};
int[] yellow = {255,255, 0};
//int[] background = { 85, 85, 85};
int[] background = { 255, 255, 255};
// The original image data will be stored on this array.
int[][][] imageData = new int[width][height][3];
// We'll fill the array with a test pattern bars thingie.
double[] pixelArray=null;
for(int w=0;w<width;w++)
for(int h=0;h<height;h++)
if(bi.getRaster().getPixel(w,h,pixelArray)[0]>=9000){
//lo dejo blanco
imageData[w][h] = background;
else if(bi.getRaster().getPixel(w,h,pixelArray)[0]>=alto){
//lo dejo rojo
imageData[w][h] = red;
else if(bi.getRaster().getPixel(w,h,pixelArray)[0]>=medio){
//lo dejo amarillo
imageData[w][h] = yellow;
else{
//lo dejo verde
imageData[w][h] = green;
// Now we have a color image in a three-dimensional array, where the
// third dimension corresponds to the RGB components.
// Convert the color image to a single array. First we allocate the
// array.
// Note that this array will have the pixel values composed on it, i.e.
// each R,G and B components will yield a single int value.
byte[] imageDataSingleArray = new byte[width*height*3];
int count = 0;
// It is important to have the height/width order here !
for(int h=0;h<height;h++)
for(int w=0;w<width;w++)
// Rearrange the data in a single array. Note we revert RGB, I still don't
// know why.
imageDataSingleArray[count+0] = (byte)imageData[w][h][2];
imageDataSingleArray[count+1] = (byte)imageData[w][h][1];
imageDataSingleArray[count+2] = (byte)imageData[w][h][0];
count += 3;
// Create a Data Buffer from the values on the single image array.
DataBufferByte dbuffer = new DataBufferByte(imageDataSingleArray,width*height*3);
// Create an pixel interleaved data sample model.
SampleModel sampleModel =
RasterFactory.
createPixelInterleavedSampleModel(DataBuffer.TYPE_BYTE,
width,height,3);
// Create a compatible ColorModel.
ColorModel colorModel = PlanarImage.createColorModel(sampleModel);
// Create a WritableRaster.
WritableRaster raster = RasterFactory.createWritableRaster(sampleModel,dbuffer,new Point(0,0));
// Create a TiledImage using the SampleModel.
TiledImage tiledImage = new TiledImage(0,0,width,height,0,0,sampleModel,colorModel);
// Set the data of the tiled image to be the raster.
tiledImage.setData(raster);
// Save the image on a file.
JAI.create("filestore",tiledImage,output,"TIFF");
ThanksI tried that. When I open one image and set the exposure, then go to open the second image, nothing happens. I then saved one image as a psd file, then it would let me open the raw file a second time. When I had both open on the same screen and dragged the layer from one into another image, the layer size ended up being different than the other file. It was shifted down and to the left. I need these images to be pixel locked, and the user experience I went through did not allow me to do this.
I also do not see a way to copy/paste layers between files. -
In Preview, I suddenly am unable to get the "Adjust Color" tool panel to edit images. I just get the rectangular image selection tool instead. How do I ge the "Adjust Color" tool panel back?
Hmmm, I wonder if that window is hidden or off screen? Have you moved the pic window around to look under it?
Might try this...
