Binary 2D image array

I'm lookking for a solution for this problem: I have a binary 2D array of an image. Now I want to search for and count all "1" (= high) values in the 2D array. Please help me to solve this problem. Thx.

I don't know what a "binary image array" is, but if you mean a 2D boolean array, you can wire it into Boolean to (0,1) and wire the output of that into Add Array elements (Boolean and Numeric palettes).
If that doesn't help, you should post your VI so we can see what your array looks like.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

Transform jpeg image to binary coded image

how to transform jpeg image to binary coded image? using which properties? thanks .

well, I dont think so. but what exactly do you need, transforming it into bits or bytes?
well, I have no time to do the program for you, but this is the idea:
FileInputStream inputF=null;
File imageF;
byte content [];
try {
    imageF=new File ("The image path");
    content=new byte [(int) imageF.length ()];
    inputF=new FIleInputStream ("the image path");
    inputF.read (content);
} catch (Exception E) {
}and thats all to have a byte array with the bytes of the image.

Please Help!-Problem using Image[ ] array

Hi everyone,
I have this real confusing bug in my code which i am not able to fix.
Image[] tmpImg = new Image[Img.size()]; /initializing an image array tmpImg
 for(int i=0; i<Img.size(); i++) { //i require this display the image a number of times
 try{
 icon = Image.createImage("/Icon.png");
 im = new ImageItem("Image", icon,ImageItem.LAYOUT_CENTER,"image"); //using a imageItem to display the image in a form
 form.append(im);
 icon2 = Image.createImage("/Icon2.png");
 im2 = new ImageItem("Image2",icon2,ImageItem.LAYOUT_CENTER,"image"); //using another imageItem to display the second image
 form.append(im2);
 if (imageValue.elementAt(i) == "availableImage") {
 tmpImg[i] = icon; //assigning the value to the image array based on a condition from a String Vector
 if (imageValue.elementAt(i) == "offlineImage") {
 tmpImg[i] = icon2; //assigning the value to the image array based on a condition from a String Vector
 } catch(IOException err) {}
 System.out.println(tmpImg[0]);
 System.out.println(tmpImg[1]);
 System.out.println(tmpImg[2]);
 System.out.println(tmpImg[3]);
 return tmpImg;
 }My problem is that when i try to print tmpImg[0], tmpImg[1] etc all the values are printed null. But the Image is created and being displayed on a ImageItem. but i am not able to assign the image to the image array 'tmpImg' which is within an if condition.
Can anyone tell me why is this so. I would be grateful
Thank You

Thank u deepspace
I got a lil' frustrated, so completely did not think that way. The code is working now
Thanx again

Piv to Image Array

I have a program on my computer called Pivot Stickfigure Animator which I use to make graphics. Is there a way to read a Pivot file into an Image Array?

Read Binary(raw Image) data from a file

Hi
PLEASE HELP, I want to Read Binary(Raw Image)data (16 bit integer) from a file and display on the JPanel or JFrame.

Hi, you'll need to use MemoryImageSource.
You read each RGB triple and add it to a pixel[].
Heres the roughg idea.
Hope that helps.
Harley.
int width,height;
int[] pixels = new int[width*height];
while(!fileDone)
for(int i=0; i<(width*height) i++){
int rgb = inputStream.readInt();
pixels[i] = rgb;
DirectColorModel colorModel = new DirectColorModel(16,0xff00,0x00ff,0x00ff);
MemoryImageSource memImage = new MemoryImageSource(width,height,pixels,0,width));

32 Bit Image to Image Array

I am attempting to get an image array from a 32 Bit image. I
attempted to use IMAQ ImageToArray. This did not work when
passing in a 32bit RGB image. It works fine after I convert the
image to 8 or 16 bit image, but this is a step I am attempting to
remove. So, my main questions is there a way to get an Array of
an image directly from a 32 Bit Image?

In the Color Utilities there is a function called IMAQ Color Image to
Array. That is the one you want to use. Hopefully you have the Vision
Development module or you may not have access to this vi.

Need Help Creating Image Array

Hello,
I am a newbie at Flex 2 and I am working on this site that
needs an image array consisting of 5 images. The ideal thought
would be for the images to load into an HBox I created as a holding
place and have the images change every 5 seconds or so. I have
looked around the forums and the internet but I have yet to find
anything. If anyone can please help me on this I would greatly
appreciate it.
Regards,
Jose

If you've done what I think you have, then I may have tried something similar.
I tried creating a BufferedImage in a JPanel, basing the size of the BufferedImage on the size of the JPanel in the constructor, but when the JPanel was created, it tried to set up the image before resizing the JPanel i.e. the BufferedImage size was set to (0,0) and that threw an IllegalArgumentException at runtime. I found that I had to declare variables for an initial image size, then optionally change the image size later.
Hope that helps.

Problem displaying binary tif image from rfc

Hello All,
I am trying to display an image that is returned from RFC as binary image
Context description:
Context Node From RFC - Out_Et_Image node type tbl1024
Node element Line
As I understand the node is representing a byte array and each Line element i a part of the array .
i did
1. merge it into one byte array :
int ArrayTot = 0 ;
for ( i =0;i<wdContext.nodeOut_Et_Image().size();i++){
 ArrayTot = ArrayTot+wdContext.nodeOut_Et_Image().getOut_Et_ImageElementAt(i).getLine().length ;
 final byte[] pictureContentTemp1 = new byte[ArrayTot];
 for ( i =0;i<wdContext.nodeOut_Et_Image().size();i++){
 if(i>0){
 j=j+wdContext.nodeOut_Et_Image().getOut_Et_ImageElementAt(i-1).getLine().length;
 System.arraycopy(wdContext.nodeOut_Et_Image().getOut_Et_ImageElementAt(i).getLine(),0,
 pictureContentTemp1,0,wdContext.nodeOut_Et_Image().getOut_Et_ImageElementAt(i).getLine().length );
 }else{
 j=wdContext.nodeOut_Et_Image().getOut_Et_ImageElementAt(i).getLine().length;
 System.arraycopy(wdContext.nodeOut_Et_Image().getOut_Et_ImageElementAt(i).getLine(),0,
 pictureContentTemp1,j,wdContext.nodeOut_Et_Image().getOut_Et_ImageElementAt(i).getLine().length );
2. using the IWDCachedWebResource to generate and display it
IWDCachedWebResource resource = WDWebResource.getWebResource
(pictureContentTemp1,
WDWebResourceType.GIF_IMAGE);
resource.setResourceName("pic");
try{
IWDWindow window = wdComponentAPI.getWindowManager().
createExternalWindow(resource.getURL(), "gggg", true);
// Eliminate some features of the window
window.removeWindowFeature(WDWindowFeature.ADDRESS_BAR);
window.removeWindowFeature(WDWindowFeature.MENU_BAR);
window.removeWindowFeature(WDWindowFeature.STATUS_BAR);
window.removeWindowFeature(WDWindowFeature.TOOL_BAR);
window.setWindowSize(780,430);
window.setWindowPosition(20,140);
window.open();
}catch (Exception e){
 wdComponentAPI.getMessageManager().reportException(e.getLocalizedMessage(),false);
The problem is that I get a corrupted file and i cant see or open it .
Some more details:
The original image size is 42,234 bytes
i get from the RFC after merging the array 43,008 bytes i think that the extra bytes that a get are the problem , but i don't have any idea how to get rid of them or solve the problem .
My WAS version is nw04 sp19
Does any one encounter this problem? Or can guide me what to do?
Thanks
Ronen

Get binary from image

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
Fraser

try {
            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.

How do i convert a picture back to a image array and extract the coulor table.

Been trying to do so for the past 2 weeks and the folks at NI India also are unable to support me. please help. I am on labview 6.1
Ankur

I suppose that you are talking about a LV picture.
My opinion is that LV 6 was an absolute pity for picture management. LV 7 is only a pity.
Your problem could be solved in a breath using a few of the IMAQ vision tools. Unfortunately, NI has decided to keep separated its image management tools from its graphic development environment. I think that this situation should be discussed...
With LV 6, there is probably a solution that use the Flatten to String function, convert the string to a 1D-array of bytes, remove the 32 bytes or so the Flatten function has added before the actual picture bytes, then reshape the array according to the initial picture size. I have done that in the past for a 8byte picture. Not sure if it is as simple for a colored picture. Not sure either if I'll have some time to spare on the problem today.
Hope you will find here some more constructive help !

Binary File to Array

I need to choose a file with a file chooser and then convert it to an array. The file is a binary file and I just want every byte out of it as an element in a very large byte array. Im not quite sure how to go about this, can someone who has done this or knows how guide me in the right direction?
When I run the enclosed vi it acts as if the file is not 512 bytes big and says that an EOF has been reached. Im sure Im just doing it plain wrong tho .
The zip contains two of the files I wish to read in as well as my poor attempt to read the file into a byte array. The vi has two main problems:
1) It doesn't work
2) It doesn't take into account variably sized files
Thanks

(1) You wire a byte stream type of I32, meaning you read 4x as many bytes as intended.
--> solution: right click in the type constant and select Representation:U8.
(2) You can get the actual file size e.g. with the eof function.
See attached modification (LabVIEW7.1).
... and don't forget to close the file when done

Image array applet freezes

I'm using a modified version of Romain Guy's music shelf (http://www.curious-creature.org/2005/07/09/a-music-shelf-in-java2d/), using it as an applet in an extension for a mozilla based media player.
In order to allow decent performance I'm using a proxy pattern, so the images are not actually loaded until they're needed. All the proxies are stored in a simply java array at startup. When more than 100 of the proxies have loaded their image, the whole thing slows down, and when 113 (exactly and always) have loaded, the applet freezes completely.
Anyone got any idea why this might be happening?? There's plenty of memory left and the applet is run localy so it shouldn't be security probem either.

Nevermind..... a classic case of RTFM. I might have enough memory, but java only has 64mb....

Image Array , GUI Issue

I am currently trying to insert a 20X20 image a specific spot on an array spot[X][Y], but do not know how to get them in the array.
Can anyone help me?

And sorry im a Beginner, but would this mean i would have to make 100 separate JLabels to fill the 10X10 grid for the array?Yes, you'd have to make 100 JLabel objects, but not 100 separate JLabel variables as all the JLabel objects would be held in a single 10 by 10 array.
Is this a memory game application?
