Hello, my issue this time is establishing a 2-D array of images. I input a 600x600 files, which I then take and divide by rows and cols. Then I want to make 4 300x300 squares, displaying the bottom corner at the end. I get initalizing errors, which Im not sure how to correct. Any help is appreciated, thanks.

I get initalizing errors, which Im not sure how to correct.

... which are..?

[g00se]

I see

	myImagePiece = new Image[numCols][numRows];
        for (int c = 0; c < numCols; c++) {

[peepsrct]

Thanks, but decided to go a different direction. I loaded the image section to a tmp, then moved to the array of images. Compiled, but I now get this error.

The last code i posted should solve your problem

[peepsrct]

Yes, it pointed me in the right direction. Thanks again. I got past that part and am now stuggling a little with getting a new JFrame to show the pieces all together but hopefully should come together shortly.

Thanks again.

[peepsrct]

Hello again, I've been trying to work different ways but I can't seem to get my showPuzzle method to work correctly. At the moment I've been trying to input 2 row, 2 col of a 600x600 image. Then simply trying to divide it evenly and show one instance of it ([1],[1]) or lower right corner.

Complies and Runs fine, but when you click compute it doesn't pop up new window, or show image. Thanks for help.

Why do you expect it to show an image when you push the Choose button? You have no code that indicates that this is the case. If so, you will need to put it in the actionListener under the CHOOSE area.

[peepsrct]

Wow, totally overlooked that issue. Must have deleted some code while editing it all. Though I now get following NullExceptionerror, I believe within my cropImage() as the last output recieved before is of cVal. Going to work on my crop loop, thinking do to rounding dividing odd number gonna mess up my pieces a tad. Thanks.

cVal= 106
rVal= 118

I'm not sure, but I remember something about the Toolkit way of loading images...I think you might need to call prepareImage() on the image object RIGHT after creating it with Toolkit. I have always used the ImageIO class and have gotten really good results. Perhaps you can check it out.

[peepsrct]

Before I used my cropImage to just take one chunck off a image(top 100x100), and it worked. Only thing I changed in it was the two loops, so I still need to check into that. I'll look into ImageIO as well, do you think it would be more suited for the tasks I need to perform? Those being:

1) Get Picture cut up into pieces
2) Display them on clickable buttons, that are then randomized to form a "puzzle game" that user rearranges.

[peepsrct]

I fixed my errors, and got a window to dislpay alas! However I still get a NullPointer on this statement, any help?

showLabel.setIcon(new ImageIcon(myImagePiece[1][1]));

Hi, within a current project I've been trying to display a image after cropping it, though at this line I get a null pointer exception. Any help is appreciated, Thanks ahead of time.

public void showPuzzle()
{
	JFrame sP=new JFrame("Show Puzzle");
	super.repaint();
	JPanel	showPanel;
	JLabel	showLabel;
	Container cp2;

        showLabel=new JLabel();
	showLabel.setIcon(new ImageIcon(myImagePiece[1][1]));   // Throws here.
	showPanel=new JPanel(new FlowLayout());
	showPanel.add(showLabel);
	cp2=getContentPane();
	cp2.add(showPanel);
	sP.add(cp2);

	setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	setSize(500,500);
	setLocation(new Point(300,200));
	setVisible(true);
}

Here is where I create this image:

public void cropImage()
{
		ImageProducer imProducer;
		CropImageFilter	cropFilter;
		FilteredImageSource	croppedImageProducer;

		System.out.println("Attempting to Crop Image");

		myImage=Toolkit.getDefaultToolkit().getImage(getStr);
		MediaTracker mTracker=new MediaTracker(this);
		mTracker.addImage(myImage,1);
		try
		{
		mTracker.waitForID(1);
		}
		catch(InterruptedException e)
		{
			System.out.println("ERROR FOOL..");
		}
		int imgW=myImage.getWidth(null);												// Image width
		int imgH=myImage.getHeight(null);												// Image Height
		int cVal=imgW/numCol;															// Width/NumColumns
		int rVal=imgH/numRow;															// Height/NumRow

		for(int c=1;c<numCol;c++)
		{

			for(int r=1;r<numRow;r++)
			{

				cropFilter = new CropImageFilter(0,0,cVal,rVal);
				imProducer = myImage.getSource();
				croppedImageProducer = new FilteredImageSource(imProducer, cropFilter);
				myImagePiece[r][c] = createImage(croppedImageProducer);
		if(imgH>rVal)
			rVal=rVal+rVal;
			System.out.println("rVal on loop #" + r + ": " + rVal);
			}
		if(imgW>cVal)
				cVal=cVal+cVal;
		}


}

3 Topics merged. Please do not create multiple topics on the same subject. Thanks!

It looks to me as if the Toolkit is not properly loading the file. You might want to look into ImageIO class. Much easier.

[peepsrct]

Thanks for the advice, it does seem to be a good option. A little hard to put my mind around at first, but once I looked into it I got the premise. However I still am getting a error thrown, this time on the statement

myImage = getImage(getStr);

And the issue:
