Converting image into byte array

Hi all,
How to convert an integer array image into byte array ?
here i have a image like this :
private static int pixelArray[] = {
0xff000000, 0xff000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000,
0xff000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000
From this one i create image like this one :
Image image = Image.createRGBImage(pixelArray, width, height, true);
Now i want to convert that pixelArray into byte array ? how to do this
additionally i want to send this byte array to servlet .
thanks in advance.

Hi,
If you want to convert your int array to a byte array you should
split each integer into 4 bytes to avoid losing information. You can
rebuild your integer array later if you need to. I think this code
will work (i havent tested it):
byte[] pixel= new byte[pixelArray.length<< 2];
for (int i= pixelArray.length- 1; i>= 0; i--) {
int aux= i<< 2; // i* 4 = i<< 2
pixel[aux]= (byte) (pixelArray>> 32);
pixel[aux+ 1]= (byte) (pixelArray[i]>>> 16);
pixel[aux+ 2]= (byte) (pixelArray[i]>>> 8);
pixel[aux+ 3]= (byte) pixelArray[i];

Convert image into TIFF 4

I have a requirement to convert images from TIFF 6 to TIFF 4. I have been able to convert to TIFF without compression. However, to reduce the file sizes I need to implement compression_group4. Although it is listed as being supported . . . it does not appear to be.
Any ideas?

(1) Are you using compression? I can create TIFFs but not compress them using .COMPRESSION_GROUP4
(2) When I try and use JAI's ImageCodec (specifically TIFFEncodeParam) and specify COMPRESSION_GROUP4 I get a run-time error: "java.lang.Error: Unsupported compression scheme specified."
(3) This error seems to be generated by the line .setCompression, as I have been able to generate the error without specifying an image. (ie: it's not related to this image not being supported)
(A) Here is the code I'm using:
OutputStream os = new FileOutputStream(destinationFile); //where destinationFile is a File object representing the saved file
TIFFEncodeParam param = new TIFFEncodeParam();
param.setCompression(TIFFEncodeParam.COMPRESSION_GROUP4);
ImageEncoder enc = ImageCodec.createImageEncoder("TIFF", os, param);
enc.encode(src); //where src is a RenderedImage Object
os.close();
any ideas?
Thanks in advance!

Help regarding converting images into blocks of 8X8

Hi,
Please could anyone help me with the source code for converting an image(of any type) into blocks of size 8X8.
I need these blocks as an input for DCT conversion for Watermarking the image
Thanks in advance

Hello
You can migrate a SAPscript form into a Smart Form and convert a SAPscript style into a Smart Style.
When converting a SAPscript style into a Smart Style, the system converts all paragraph and character formats with all their properties and attributes without any changes. Thus you can use the converted Smart Style without making any adaptations.
When migrating a SAPscript form into a Smart Form, the system executes the following steps:
It copies the language attributes and the output options.
It migrates the layout information including pages, windows, and their attributes and positions on the page.
It copies the texts in the form.
It displays the fields (SAPscript notation: program symbols) in the texts.
It converts the SAPscript commands (such as NEW-PAGE or IFu2026ENDIF) to comment lines and displays them in the texts.
After the migration, you have a template that you can enhance and modify according to your needs. Adapt the form logic by specifying the commands which the system converted to comment lines.

Convert image into dots

How can I create a fade (for my purposes, from black to white) using identically sized individual dots? I don't want halftone, because the size of the dots varies. I want a fade, starting from 100% concentration (black, with no space) to 0% concentration (no dots). Anyone know how to do this? Thanks!

Make a gradient and use the Color Halftone filter on it. Convert to grayscale first because you only want the black dots, and change the screen angle to 90 degrees.
Use as overlay, or as a mask:

How to convert image to array pixel values in java

I would like to know how to convert image into arrary of pixels in java ?
which API should i use ?
please give me link to a sample program !

I find the most efficient way to just walk over the image and call getRGB(x,y) on every pixel, more so than Pixelgrabber. If someone knows a more efficient way, give me a beep.

Preserving alpha while converting images to grayscale

I am trying to convert images into grayscale.
I use this code
public static BufferedImage grayScale(BufferedImage im) {
        BufferedImage image = new BufferedImage(im.getWidth(), im.getHeight(), BufferedImage.TYPE_BYTE_GRAY);
        Graphics g = image.getGraphics();
        g.drawImage(im, 0, 0, null);
        g.dispose();
        return image;
    }but transparent parts become black. Is there a simple way to preserve opacity while converting to grayscale.

Since you want to preserve the alpha channel you'll need to get and set the pixels yourself. And you'll have to use a BufferedImage type that
supports an alpha channel. TYPE_BYTE_GRAY won't do...
public static BufferedImage grayScale(BufferedImage im) {
     BufferedImage grayImage = new BufferedImage(im.getWidth(), im.getHeith(), BufferedImage.TYPE_INT_ARGB);
     for(int x = 0; x < im.getWidth(); x++)
          for(int y = 0; y < im.getHeight(); y++){
               int argb = im.getRGB(x,y);
               int a = (argb >> 24) & 0xff;
               int r = (argb >> 16) & 0xff;
               int g = (argb >> 8) & 0xff;
               int b = (argb      ) & 0xff;
               int l= (int) (.299 * r + .587 * g + .114 * b) //luminance
               grayImage.setRGB(x,y, (a << 24) + (l << 16) + (l << 8) + l);
     return grayImage;
}

Load a redrawn image into a JLabel and save it into a BufferedImage?

Hello, I'm doing a small application to rotate an image, it works, but I'd like to show it into a JLabel that I added, and also store the converted image into a BufferedImage to save it into a database, this is what I have so far:
public void getImage() {
try{
db_connection connect = new db_connection();
Connection conn = connect.getConnection();
Statement stmt = conn.createStatement();
sql = "SELECT image " +
"FROM image_upload " +
"WHERE image_id = 1";
rset = stmt.executeQuery(sql);
if(rset.next()){
img1 = rset.getBinaryStream(1);
buffImage = ImageIO.read(img1);
rset.close();
} catch(Exception e){
System.out.println(e);
public void paint(Graphics g){
super.paint(g);
Graphics2D g2 = (Graphics2D) g;
ImageIcon imgIcon = new ImageIcon(buffImage);
AffineTransform tx = AffineTransform.getRotateInstance(rotacion, imgIcon.getIconWidth()/2, imgIcon.getIconHeight()/2);
g2.drawImage(imgIcon.getImage(), tx, this);
jLabel1.setIcon(imgIcon);
private void jButton1MouseClicked(java.awt.event.MouseEvent evt) {
// TODO add your handling code here:
setRotacion(getRotacion() + 1.5707963249999999);
repaint();
I get the image from a db, then using the paint() method I rotate the image, it works, but the new image is outside of the JLabel and I don't know how to assign the new one into the JLabel (like overwritting the original) and also how to store the new image into a BufferedImage to upload it into the database converted, thanks in advanced, any help would be appreciated, thanks!!

I was able already to fill the JLabel with the modified content, just by creating a new BufferedImage, then create this one into a Graphics2D object and the drawing the image into it, last part, inserting the modified image into the database, so far, so good, thanks!
EDIT: Ok, basic functionality is ok, I can rotate the image using AffineTransform class, and I can save it to the database and being displayed into a JLabel, now, there's a problem, the image for this example is 200 width and 184 height, but when I rotate it the width can be 184 and the height 200 depending on the position, but the BufferedImage that I create always read from original saved image:
bimage = new BufferedImage(buffImage.getWidth(), buffImage.getHeight(), BufferedImage.TYPE_INT_ARGB);
Is there a way that I can tell BufferedImage new width and height after rotate it? :( as far as I understand this cannot be done because before the image bein rotated the bufferedImage is already created and, even being able to do it how can I get width and height from rotated image? thanks!

How do I stop FireFox from converting css3 transforms such as scale, or rotate, into matrix transforms?

Go to pilatch.com/cards and click any of the cards in the arc. Now do the same in Chrome, or Safari, or IE 9. I have un-min-catted all my JavaScript, so you can see what's going on more easily.
CSS3 transforms in version 16 of FireFox are being converted into matrix transforms.
It pretty much horks my rotate and scale animations.
For instance, if you set the style attribute of an element to something like, style="transform:scale(0.75)", FireFox immediately converts that element's transform property, such as <element>.style.transform to "matrix(...)".
I know how to do the linear algebra to convert rotate and scale via jQuery cssHooks into matrix transformations, and I've even written code to detect this "feature" of a browser, (that it forces a transform into matrix), and return a different hook that writes a matrix transform instead of a rotate transform, or scale, all in the past two days, on my development site.
However, it's proving to be increasingly challenging to make this new feature compatible with jQuery's animations. Going further, I may have to hack jQuery just to make this work for FireFox, or drop FireFox animation support altogether unless some FireFox developers make their new implementation backwards compatible.
I know that transforms normally get converted into matrices behind the scenes in the rendering engine. Leave your matrix there. Don't overwrite what the user has put in for a transform!
I also know that I should be using CSS3 animations, but, dangit, I started this project before those had widespread support. I can't rewrite all my animations because I want to support FireFox. That's not really an option. I'll direct my users to Chrome instead. I have more features in development that use these types of animation, and I'm in too deep to turn back.
Thanks for your consideration. Please contact me as you learn more about this.

Is there any way of converting a jpeg image into a vector in Fireworks? Deity Babbage, where be thee?

I am hoping for a quick way of converting images (jpeg etc) into a vector.
Is this possible?
Thanks
Eddie

Try this:
http://vectormagic.com/home
It won't work with really complex images or photos, but if you have something like a logo, it can work well. You'll need to edit the vectors it generates to smooth out some bumps and incorrect nodes, but editing a vector is much easier than drawing the whole thing from scratch.
Hope this helps!

How to convert 24bits png image into 8 bits image

Hi,
I have gone through some of threads in this forum on changing color bits. But, I still can find right way to change my image (24bits) into different color bits(8 bits). The reason i want to change the color bits because I am getting a GIF image from map server, convert it into PNG format then rescale then into size of mobile phone screen.The PNG image is really has large data length , so the it took a while to load the whole image on screen.
Note : The following code is taken from few threads in this forum and i have modified it to suit my application.
I have no idea about Java2d...any help really appreciated...Thanks in advance!!!
My code is as follow:-
public File Scale(int width, int height, BufferedImage ImgSrc)
     try
               //BufferedImage bi = ImageIO.read(ImgSrc);
               //int w = bi.getWidth(), h = bi.getHeight();
     //Image oldRescale = bi.getScaledInstance(i, j, Image.SCALE_SMOOTH);
     BufferedImage Rescale = rescale(ImgSrc, width, height);
               //ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_GRAY);
               //ColorConvertOp op = new ColorConvertOp(cs, null);
               //Rescale = op.filter(Rescale, null);
     File outfile = new File("map.png");
               ImageIO.write(Rescale, "png", outfile);
               BufferedImage fromFile = ImageIO.read(outfile);
               ColorModel cm = fromFile.getColorModel();
               System.out.println(cm.getClass() + ", bits/pixel=" + cm.getPixelSize());
          catch(Exception e)
               e.printStackTrace();

     g2.drawImage(src, 0, 0, w, h, null);

          RenderingHints.VALUE_RENDER_QUALITY);

     public static BufferedImage rescale(BufferedImage src, int w, int h)
int transparency = src.getColorModel().getTransparency();
GraphicsConfiguration gc = getDefaultConfiguration();
BufferedImage tgt = gc.createCompatibleImage(w, h, transparency);
return copyRescaled(tgt, src);

First, we need to be clear about what you're trying to do -- is it rescale an
image or insure that the image is saved with a 8bit pixel depth? Or both? You are also
using GraphicsConfiguration's createCompatibleImage, which is excellent if you are going
to display the image immediately because it might be hardware accelerated
or compatible with hardware format, but you mentioned mobile phone screens, so
there is no advantage to using GraphicsConfiguration in that case, and if fact, it's
probably changing your ColorModel when you're not looking.

Using QuickTime Pro to convert a series of JPEG images into a QT movie?

Can I use QuickTime Pro to convert a series of JPEG images into a QT (uncompressed) movie? Thanks...
Windows XP

Yes.
One of the features of the QuickTime Pro upgrade is "Open Image Sequence". It imports your sequencially named (1.jpg, 2.jpg) liked sized images (any format that QT understands) and allows you to set a frame rate.
http://www.apple.com/quicktime/tutorials/slideshow.html
You can also adjust the frame rate by adding your image .mov file to any audio clip. Simply "copy" (Command-A to select all and then Command-C to copy) and switch to your audio track.
Select all and "Add to Selection & Scale". Open the Movie Properties window and "Extract" your new (longer or shorter) file and Save As.
As you've posted in the Mac Discussion pages but your profile says XP you'll need to subsitute Control key where I reference Command key.
