Problems with BufferedImage
Hi, i'm very new to Java.
What I'm trying to do is process the individual pixels of an image. So far I have the following code:
BufferedImage inputImage;
public void loadImage()
try
File input = new File("face.jpg");
inputImage = ImageIO.read(input);
catch (IOException e)
JFrame frame = new JFrame();
JOptionPane.showMessageDialog(frame,
"File input Error!","Error", JOptionPane.ERROR_MESSAGE);
}This loads the Image, from a jpg.
Next I am trying to get the color data from an individual pixel so I tried this:
int[] pixels =
img.getRGB (5, 5,img.getWidth()-5,img.getHeight()-5,null, 0,img.getWidth()-5);
JFrame frame = new JFrame();
JOptionPane.showMessageDialog(frame,
"" + (int)pixels[1],"PixelColor", JOptionPane.ERROR_MESSAGE);However it always gives me a Coordinates out of bound exception, I am pretty sure img.getWidth() is returning the actual width of the image
if i put in a small values say (5 ) for width and height and scan size it does return something but it looks like gobbeldy gook -16734 does not seem like an actual pixel value!
Also I have another question how do I println to the console? Thanks
Salik
Yes I have verified that getWidth and getHeight return the proper height width of the image.
here's the actual error:
java.lang.ArrayIndexOutOfBoundsException: Coordinate out of bounds!

at java.awt.image.BufferedImage.getRGB(Unknown Source)

Problem with BufferedImage.getScaledImage()

GetBlue() problem with BufferedImage
hi i have an bmp image that i want to know the blue color component for the first pixel of the pixel array i create from the image
the problem i have is that the pixels[0]=-10718816 and i get an "IllegalArgumentException --> More than one component per pixel", i thing is because the number should be between 0 and 255. but im not really sure...
please some one help me.
i just need to get the blue color component from the first pixel of an pixels int array from image loaded with BufferedImage
BufferedImage img = null;
String pix="";
//here i load the image into the BufferedImage
img = ImageIO.read(new File("C:\\1sierra.bmp"));
//here i load the intArray with the rgb pixels of my BufferedImage
int[] pixels = img.getRGB(0,0,img.getWidth(),img.getHeight(),null,0,img.getWidth());
//here i try to get the blue color component and i get the exception
pix =Integer.toString(img.getColorModel().getBlue(pixels[0]));You want to use a bit-wise AND and not the MOD operator.
public class TryInt
public static void main( String[] args )
int i = 0xFFFFFFFF;
System.out.println( i & 0xFF ); // output: 255
System.out.println( i % 255 ); // output: -1
}The most significant byte of an RGB int value often holds the Alpha value which is typically 0xFF.

Problem with BufferedImage & "getGraphics()" / "createGraphics()"
I try to create with a servlet a Graphics2D Object with the method "createGraphics()" from a BufferedImage Object. Therefore I use the following code:
BufferedImage bufferimage=new BufferedImage(100,100,BufferedImage. TYPE_INT_RGB);
Graphics2D g2;
g2=bufferimage.createGraphics();
With the Graphics2D Object I wanna draw into the BufferedImage Object:
g2brut.drawLine(5,5,30,30);
The servlet runs fine on a Windows-PC with Apache and Jserv. On a Linux-PC the same code doesn't work: The method createGraphics() creates a bug and the servlet doesn't run any longer.
Hope someone could help!If there are no graphical components in your Linux system, like X-Windows or something, you don't have the capabilities to use the drawing package. AWT is system-dependent and without drawing routines on your system, you can't access drawing functions in Java. Assuming this is the problem, there's a package out there that gets around that by providing system-independent access to AWT. I've only heard of the problem, never faced it myself so I don't know exactly how to implement it, but my friend ran into the same problem and solved it this way.

Problem with Background image and JFrame
Hi there!
I've the following problem:
I created a JFrame with an integrated JPanel. In this JFrame I display a background image. Therefore I've used my own contentPane:
public class MContentPane extends JComponent{
private Image backgroundImage = null;
public MContentPane() {
super();
* Returns the background image
* @return Background image
public Image getBackgroundImage() {
return backgroundImage;
* Sets the background image
* @param backgroundImage Background image
public void setBackgroundImage(Image backgroundImage) {
this.backgroundImage = backgroundImage;
* Overrides the painting to display a background image
protected void paintComponent(Graphics g) {
if (isOpaque()) {
g.setColor(getBackground());
g.fillRect(0, 0, getWidth(), getHeight());
if (backgroundImage != null) {
g.drawImage(backgroundImage,0,0,this);
super.paintComponent(g);
Now the background image displays correct. But as soon as I click on some combobox that is placed within the integrated JPanel I see fractals of the opened combobox on the background. When I minimize
the Frame they disappear. Sometimes though I get also some fractals when resizing the JFrame.
It seems there is some problem with the redrawing of the background e.g. it doesn't get redrawn as often as it should be!?
Could anyone give me some hint, on how to achieve a clear background after clicking some combobox?
Thx in advanceI still prefer using a border to draw a background image:
import java.awt.*;
import java.awt.image.*;
import javax.swing.border.*;
public class CentredBackgroundBorder implements Border {
private final BufferedImage image;
public CentredBackgroundBorder(BufferedImage image) {
this.image = image;
public void paintBorder(Component c, Graphics g, int x, int y, int width, int height) {
int x0 = x + (width-image.getWidth())/2;
int y0 = y + (height-image.getHeight())/2;
g. drawImage(image, x0, y0, null);
public Insets getBorderInsets(Component c) {
return new Insets(0,0,0,0);
public boolean isBorderOpaque() {
return true;
}And here is a demo where I load the background image asynchronously, so that I can launch the GUI before the image is done loading. Warning: you may find the image disturbing...
import java.awt.*;
import java.io.*;
import java.net.URL;
import javax.imageio.*;
import javax.swing.*;
import javax.swing.border.*;
public class BackgroundBorderExample {
public static void main(String[] args) throws IOException {
JFrame.setDefaultLookAndFeelDecorated(true);
JFrame f = new JFrame("BackgroundBorderExample");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JTextArea area = new JTextArea(24,80);
area.setForeground(Color.WHITE);
area.setOpaque(false);
area.read(new FileReader(new File("BackgroundBorderExample.java")), null);
final JScrollPane sp = new JScrollPane(area);
sp.setBackground(Color.BLACK);
sp.getViewport().setOpaque(false);
f.getContentPane().add(sp);
f.setSize(600,400);
f.setLocationRelativeTo(null);
f.setVisible(true);
String url = "http://today.java.net/jag/bio/JagHeadshot.jpg";
final Border bkgrnd = new CentredBackgroundBorder(ImageIO.read(new URL(url)));
Runnable r = new Runnable() {
public void run() {
sp.setViewportBorder(bkgrnd);
sp.repaint();
SwingUtilities.invokeLater(r);

Hi everyone,
I have been trying to get this GUI built from the ground up and I have encountered a problem with the GridBag(exception error that the fields being added can not be done. Also, my method main seems to be off track, I have a working program which the display fields have been modified to display object and everything else is the same except that I can not get the GUI to run.
The following is the code and any suggestions as to what I can do to get this going will be appreciated. Thank you.

I took your advice and decided to take a different approach to the problem I am having, I decided to stay somewhat with the basics with little knowledge I have about coding. I am new to this and I am trying to learn through the fire but it's getting hot so if you don't mind, can you tell me what I need to do to fix the error messages I am getting.
1. "else" without "if',
2. can't load my icon-a JPG
3. exception in thread amin
process complete.
4.Text area for displaying an iteration of the input
the code is not as long as the other one! any help will be appreciated. Also I am attaching the code to the GUI that does work but I can not seem to get the actionListener aspect to work. Thanks again.
//this one works and it serves as a model for what I am //trying to do in the fields. as well as designate a text area //where a each entry per iteration of input is displayed

I have a problem with the getRGB(int x, int y) method of the BufferedImage class :
I've load an image in it :
1:// b is my bufferedimage clas and myimage is an image
2:b.getGraphics().drawImage(myimage, 0, 0, this);
3:// g is the graphics object of my paint method
4:g.drawImage(b, 634, 225, null);
5:// This write -16777216 and 10, 10 is a black point
6:System.out.println(b.getRGB(10, 10));
I think the problem is at the second line. But i'm not sure. Can somebody help ?That's probably not what you meant. You can do a binary and:int r = (hex & 0x00FF0000) >> 16;
int g = (hex & 0x0000FF00) >> 8;
int b = (hex & 0x000000FF); -
Problem with affinetransformOp method...
I have a serious problem with filter method
I Want to make a image flipping or some other filtering by using
AffineTransformOp
but it printouts an erro like this
cannot resolve symbol
op.filter (img, flipped)
(the error pointer shows ".after the op")
a code from my one of the filters
BufferedImage flipped = new BufferedImage(img.getHeight(), img.getWidth(),BufferedImage.TYPE_INT_RGB);
AffineTransform trans = new AffineTransform(0, 1, 1, 0, 0, 0);
AffineTransformOp op = new AffineTransformOp(trans, AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
op.filter(img, flipped); //img is my buffered image source
I used some other ways like (img, null) but always give out error.
thanks..Did you declare "img" as BufferedImage or something else?
What is the full error message? -
Problem with Transparency using PixelGrabbar.
Well, im having a problem.
Im creating a basic 2d game and using images, since im using alot of images and they are being drawn alot i use a class i call "GameSprite", basically it retrieves the file needed and then keeps it in a pixel array, but transparency dosn't seem to work with it. The reason im using this is because say i have 100 images to draw, it dosn't need to keep using the drawImage method because it draws all at once using a set drawing area on which the pixel arrays are possitioned, for example this is the drawing;
public void drawGraphics(int xOffset, Graphics g, int yOffset)
setImageConsumer();
g.drawImage(drawingAreaImage, xOffset, yOffset, this);
.private synchronized void setImageConsumer()
if(imageConsumer != null)
imageConsumer.setPixels(0, 0, drawingAreaHeight, drawingAreaWidth, colorModel, drawingAreaSize, 0, drawingAreaHeight);
imageConsumer.imageComplete(2);
}Here is the basic's of what it does, note i used URL just for a test if you wanted to test (image still is uploaded there);
Image image = Toolkit.getDefaultToolkit().createImage(new URL("http://i166.photobucket.com/albums/u116/the_owner2007/testtrans.png"));
image = setTransparency(image, new Color(255, 89, 255));
ImageIcon icon = new ImageIcon(image);
imageWidth = icon.getIconWidth();
imageHeight = icon.getIconHeight();
imagePixels = new int[imageWidth * imageHeight];
PixelGrabber pixelgrabber = new PixelGrabber(image, 0, 0, imageWidth, imageHeight, imagePixels, 0, imageWidth);
pixelgrabber.grabPixels();If i use for example a JLabel and set an ImageIcon as the image the transparency works, otherwise i can't figure it out.
Here is the setTransparency method;
public static Image setTransparency(Image im, Color color) {
//the color to make transparent
final int markerRGB = color.getRGB() & 0x00FFFFFF;
ImageFilter filter = new RGBImageFilter() {
public int filterRGB(int x, int y, int rgb) {
if ((rgb & 0x00FFFFFF) == markerRGB) {
return markerRGB;
} else {
return rgb;
ImageProducer ip = new FilteredImageSource(im.getSource(), filter);
return java.awt.Toolkit.getDefaultToolkit().createImage(ip);
If you can think of an alternative solution which would work better and possibly more efficiant please feel free to post that.
Thanks.drawingAreaImage = component.createImage(this);Note that images created through this method are often times immutable. They will not respond to changes in the underlying ImageProducer. So "drawingAreaImage" is essentially a snapshot of whatever pixels "this" gave it.
An exception to this rule is if you use MemoryImageSource and set the animated flag,
int[] pixels = ....
MemoryImageSource imageProducer = ....
imageProducer.setAnimated(true);
drawingAreaImage = component.createImage(imageProducer);This time, whenever pixels is modified you can call imageProducer.newPixels() and the image will be updated.
On a side note, you are using a very old method of dealing with images (over a decade old since java 1.0 and 1.1). Are you doing this for compatability purposes? I would recommend you drop the ImageProducer/Consumer model entirely and stick with BufferedImages (which as been around since 1.2 and was the "upgrade" from the ImageProducer/Consumer model). -
Problem with session while sending a multipart-form (a file via post)
I have a problem with the communication between my applet and my server. I use a method to post an xml to my server with the Content-Type "application/x-www-form-urlencoded" and with it I'm not having any problem to preserve the session.
However I use another method I found in the forums to post files and try to adapt it, but I'm being send from the server to the login page because it's not recognizing my session
Can anybody help me? This is my method
public String uploadFile(String adr, BufferedImage img) {
String res = "";
String CONTENT_BOUNDARY = "--abvx98734732";
String s;
File f = null;
URL url;
URLConnection conn;
try {
url = new URL(adr);
conn = url.openConnection();
conn.setDoOutput(true);
conn.setRequestProperty("Content-Type",
"multipart/form-data; boundary=" + CONTENT_BOUNDARY);
conn.setRequestProperty("file-Name", "process_image.jpg");
DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
wr
.write(("--"
+ CONTENT_BOUNDARY
+ "\r\n"
+ "Content-Disposition: form-data; name=\"fileData\"; filename=\""
+ "process_image.jpg" + "\"\r\nContent-Type: image/jpg\r\n\r\n")
.getBytes());
ImageIO.write(img, "jpg", wr);
wr.write(("\r\n--" + CONTENT_BOUNDARY + "--\r\n").getBytes());
wr.flush();
BufferedReader in = new BufferedReader(new InputStreamReader(conn
.getInputStream()));
while ((s = in.readLine()) != null) {
res += s;
in.close();
catch (MalformedURLException muo) {
muo.printStackTrace();
catch (IOException io) {
io.printStackTrace();
return res;
}This is how I preserve session in my other method:
private static final String SESSION_KEY = "_session_id";
URLEncoder.encode(SESSION_KEY, "UTF-8") + "=" +
URLEncoder.encode(sessionId, "UTF-8");
wr.writeBytes(content);
....Yes, the only way is to pass the value u want in the query string. But make sure that the value is not too large.
In case you have too much info i guess the only way is to circumvent multipart and handle the process in your own custom class, which wont be worth the effort if u need pass only 2-3 small parameters.
Always,
Leo.
Hi,
Before I upload a file, I want to get a few parameter
values (getParameter) on the form first. I've tried
using com.oreilly.servlet MultipartRequest and a few
other free servlets but they require that the file
must to be uploaded first. For example:
MultipartRequest multi = new
MultipartRequest(request,filepath, 10*1024*1024);
//this will instantiate the object and upload the
file
String command = multi.getParameter("command"); //get
the form parameter
Is there any way I can get the parameter first before
uploading the file? I truly appreciate any helps you
can provide me.
Regards,
Lily -
I'm making photo album on the web. But I have a problem with thumbnails generation. I have read alot about it on this forum (thanks guys) but I have a problem:
Sometimes (but not every time) and independent on the image I've got thumbnail picture that can not be readed neither by IE or Photoshop or another programm. I'm using next encoding sequence:
PEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
com.sun.image.codec.jpeg.JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bufferedImage);
writeParam.setCompressionMode(JPEGImageWriteParam.MODE_EXPLICIT);
param.setQuality(0.7f, true);
encoder.setJPEGEncodeParam(param);
encoder.encode(bufferedImage);
And this code operate in the Servlet enviroment. So, I can not understand what is wrong?
Renat.Hi Renat.
I may be wrong but I have observed some troubles with JPEG encoding (particularly because of a lack of CPU)... You may have the same trouble... The problem is that I don't how to catch these errors but if someone knows how to, I would be really interested in... I can only catch them when I decode these images thanks to TruncatedFileException and ImageFormatException.

Problems with Overlay Layout - can anyone spot something wrong/missing?
Hi folks, I'm developing a tool that allows you to draw rectangles around objects on an image. The rectangles are then saved, and you can move between images. For some reason, though my rectangles are not drawing on the panel. I am using the Overlay Layout. Can anyone spot what I'm doing wrong? (The TopPanel canvas appears to be there, as it's taking input from the mouse - the problem is simply that the red rectangles are not drawing on the panel). Please help!!
So you know, there is a JFrame in another class which adds an instance of the ObjectMarker panel to it. It also provides buttons for using the next and previous Image methods.
Any other general advice is appreciated too.

}Regards,
EricAlright so I fixed it! I created a new class called BottomPanel extends JPanel, which I then gave the responsibility of drawing the image. I gave it an update method which took the details of the currentImage and displayed it on the screen.
If anybody's interested I also discovered/solved a problem with my mouseListener - I couldn't drag backwards. I fixed this by adding tests looking for negative widths and heights. I compensated accordingly by reseting the rectangle origin to e.getX(), e.getY() and by setting the to original_origin.x - e.getX() and original_origin.y - e.getY().
No problem! -
Problem with ImageIO.read and ImageReader GIF becomes dark
I am having problems with certain GIF images loading completely dark. I previously had problems with certain JPGs colors being distorted http://forum.java.sun.com/thread.jspa?threadID=713164&tstart=0. This was a problem in an old JDK.
Here is the code:
java.awt.image.BufferedImage bufferedImage = javax.imageio.ImageIO.read( new java.io.File("javabug.gif") );
System.out.println( bufferedImage );
javax.imageio.ImageIO.write( bufferedImage, "jpg", new java.io.File("badcolors.jpg") );
javax.imageio.ImageIO.write( bufferedImage, "png", new java.io.File("badcolors.png") );BufferedImage Read is:
BufferedImage@337838: type = 5 ColorModel: #pixelBits = 24 numComponents = 3 color space = java.awt.color.ICC_ColorSpace@119cca4 transparency = 1 has alpha = false isAlphaPre = false ByteInterleavedRaster: width = 1536 height = 1152 #numDataElements 3 dataOff[0] = 2
Here is the GIF
http://www.alwaysvip.com/javabug.gif
I am using jdk1.5.0_06
If I use java.awt.Toolkit.getDefaultToolkit().getImage instead of ImageIO.read, the problem no longer exists.
java.awt.Image image = java.awt.Toolkit.getDefaultToolkit().getImage( file.toURL() );
java.awt.MediaTracker mediaTracker = new java.awt.MediaTracker( new java.awt.Container() );
mediaTracker.addImage( image, 0 );
mediaTracker.waitForID( 0 );
java.awt.image.BufferedImage bufferedImage = new java.awt.image.BufferedImage( image.getWidth( null ), image.getHeight( null ), java.awt.image.BufferedImage.TYPE_INT_RGB );
java.awt.Graphics g = bufferedImage.createGraphics();
g.setColor( java.awt.Color.white );
g.fillRect( 0, 0, image.getWidth( null ), image.getHeight( null ) );
g.drawImage( image, 0, 0, null );
g.dispose();
javax.imageio.ImageIO.write( bufferedImage, "jpg", new java.io.File("goodcolors.jpg") );
javax.imageio.ImageIO.write( bufferedImage, "png", new java.io.File("goodcolors.png") );BufferedImage Read is:
BufferedImage@1bf216a: type = 1 DirectColorModel: rmask=ff0000 gmask=ff00 bmask=ff amask=0 IntegerInterleavedRaster: width = 1536 height = 1152 #Bands = 3 xOff = 0 yOff = 0 dataOffset[0] 0
Is this another bug in the JDK? Is there a possible workaround where I can still use ImageIO.read?I figured out the problem. It was an actual BUG in the JDK!
The code failed with the following JDKs:
java version "1.5.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_01-b08)
Java HotSpot(TM) Client VM (build 1.5.0_01-b08, mixed mode, sharing)

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_03-b07)
Java HotSpot(TM) Client VM (build 1.5.0_03-b07, mixed mode)
The code ran sucessful with this JDK:

Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)

If you are using the ImageIO classes, I highly suggest you upgrade to the latest JDK.

Problem with ImageIO.read and ImageReader JPG colors are distorted/wrong
(Using JDK 1.5)
ImageIO incorrectly reads some jpg images.
I have a jpg image that, when read by the ImageIO api, all the colors become reddish.
try
java.awt.image.BufferedImage bi = javax.imageio.ImageIO.read( new java.io.File("javabug.jpg") );
javax.imageio.ImageIO.write( bi, "jpg", new java.io.File("badcolors.jpg") );
javax.imageio.ImageIO.write( bi, "png", new java.io.File("badcolors.png") );
catch ( java.io.IOException ioe )
ioe.printStackTrace();
}Why is this happening??? My guess is there is a problem with the ImageIO.read ?
the jpg can be downloaded at http://www.alwaysvip.com/javabug.jpg
<BufferedImage@11faace: type = 5 ColorModel: #pixelBits = 24 numComponents = 3 color space = java.awt.color.ICC_ColorSpace@1ebbfde transparency = 1 has alpha = false isAlphaPre = false ByteInterleavedRaster: width = 1691 height = 1269 #numDataElements 3 dataOff[0] = 2>
I have even tried creating a new buffered image but still have the same problem:
(suggested by http://forum.java.sun.com/thread.jspa?forumID=20&threadID=665585) "Java Forums - ImageIO: scaling and then saving to JPEG yields wrong colors"
try
java.awt.image.BufferedImage bi = javax.imageio.ImageIO.read( new java.io.File("javabug.jpg") );
java.awt.image.BufferedImage out = new java.awt.image.BufferedImage( bi.getWidth(), bi.getHeight(), java.awt.image.BufferedImage.TYPE_INT_RGB );
java.awt.Graphics2D g = out.createGraphics();
g.drawRenderedImage(bi, null);
g.dispose();
javax.imageio.ImageIO.write( out, "jpg", new java.io.File("badcolors.jpg") );
catch ( java.io.IOException ioe )
ioe.printStackTrace();
}I have used the following which works but does not use the ImageIO api. However, I tried using the ImageIO to write and it worked for writing which leads me to believe there is a problem with the reader.
(suggested by http://developers.sun.com/solaris/tech_topics/java/articles/awt.html "Server-Side AWT")
try
java.awt.Image image = new javax.swing.ImageIcon(java.awt.Toolkit.getDefaultToolkit().getImage("javabug.jpg")).getImage();
java.awt.image.BufferedImage bufferedImage = new java.awt.image.BufferedImage( image.getWidth( null ), image.getHeight( null ), java.awt.image.BufferedImage.TYPE_INT_RGB );
java.awt.Graphics g = bufferedImage.createGraphics();
g.setColor( java.awt.Color.white );
g.fillRect( 0, 0, image.getWidth( null ), image.getHeight( null ) );
g.drawImage( image, 0, 0, null );
g.dispose();
com.sun.image.codec.jpeg.JPEGImageEncoder encoder = com.sun.image.codec.jpeg.JPEGCodec.createJPEGEncoder( new java.io.FileOutputStream( "goodcolors.jpg" ) );
encoder.encode( bufferedImage );
javax.imageio.ImageIO.write( bufferedImage, "jpg", new java.io.File("goodiocolors.jpg") );
javax.imageio.ImageIO.write( bufferedImage, "png", new java.io.File("goodiocolors.png") );
catch ( java.io.IOException ioe )
ioe.printStackTrace();
}BTW, the following does not work either:
java.util.Iterator readers = javax.imageio.ImageIO.getImageReadersByFormatName( "jpg" );
javax.imageio.ImageReader reader = ( javax.imageio.ImageReader ) readers.next();
javax.imageio.stream.ImageInputStream iis = javax.imageio.ImageIO.createImageInputStream( new java.io.File("javabug.jpg") );
reader.setInput( iis, true );
java.awt.image.BufferedImage bufferedImage = reader.read( 0 );I figured out the problem. It was an actual BUG in the JDK!

Serious problems with paint method, need major help
I've got a mjor problem with displaying a BufferedImage Object. My program takes in an image, i call a method on it which creates an ImageObject, imgObj, which contains the following values:
Image width, called width
Image height, called height,
array of 8 bit integers for the ARGB value of each pixel, called int [] imgCol
I've managed to create a Buffered Image of the form:
//make a buffered image ready to take the array of pixels
bufferedImage = new BufferedImage( imgObj.width, imgObj.height, BufferedImage.TYPE_INT_ARGB);
Then I set the ARGB values in the BufferedImage, by specifying the integer array of pixels, imgCol:
//set the values in the buffered image using buffered image method
bufferedImage.setRGB( 0, 0, imgObj.width, imgObj.height, imgObj.imgCol, 0, imgObj.width);
Then I try to paint it, callling repaint() in the same method as the code above.
Now when I try the following stuff I get a Null Pointer Exception:
public void paint(Graphics g){
paintImage(g);
public void paintImage(Graphics g){
Graphics2D ImageGraphic2 = (Graphics2D)g;
// Draws the buffered image to the screen.
ImageGraphic2.drawImage(bufferedImage, 0, 0, this);
Can anyone help me in fixing this problem?Here's the full stack trace, can't make heads or tails of what it's about though
