How can I find the DPI of an image? The following code tells me the size of the image in pixels which I want to convert to millimetres. When I have looked at conversions I can find - "mm = (pixels * 25.4) / dpi" but how do I find out the DPI?
public class NewMain {
/**
* @param args the command line arguments
* @throws java.io.IOException
*/
public static void main(String[] args) throws IOException {
String filename = null;
BufferedImage bimg = ImageIO.read(new File("testimage.jpg"));
int width = bimg.getWidth();
The code is used to find coordinates of an image and i cannot understand how it works.
for (int y = 0; y < height; y += 2) { for (int x = 0; x < width; x += 2) { int px1 = secureRandom.nextInt(4); int px2 = secureRandom.nextInt(4); while (px1 == px2) px2 = secureRandom.nextInt(4);
class mmm { public static void main(String[] args) { OcrEngine ocr = new OcrEngine(); ocr.setImage(ImageStream.fromFile("pp.tif")); // ocr.setImage((IImageStream) new File("pp.tif"));
[Code] ....
In above code giving error .
Exception in thread "main" com.aspose.ms.System.IO.FileNotFoundException: Can't find file: pp.tiff.
Where i am wrong. I am trying to pass all formt(.png,.gif,.jpg) images. I am giving proper path ....
Sir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.
I stored an image into MySQL database using swings and hibernate but I am struggling to retrieve that image from MySQL database and display same image in the jTable cell and same as on jLabel whatever I retrieve from the database using swings and hibernate .
I'm trying to make a method that takes an image and turns it into a tile image. So if the original image looks like this:
[URL] ....
then the output image should look like this:
[URL] ....
Here's a method that's supposed to do that but for some reason the output image looks the same as the original:
public static int[][] tile(int[][] arr){ int[][] tile = new int[arr.length][arr[0].length]; for (int i = 0; i < arr.length; i++) { tile[i]=arr[i]; } return tile; }
I recently changed the method and the error message I'm getting is "bad operand types for binary operator '+'. Here's the method:
public static int[][] tile(int[][] arr){ int[][] tile = new int[arr.length][arr[0].length]; for (int i = 0; i < arr.length; i++) { for(int j=0; j<arr[i].length;j++){ tile[j]=(tile[j])+(arr[i]); } } return tile; }
I'm trying to add an image icon to my application but since the code will be checked by another computer, I cannot use an image in my computer and use its file address. If I save the image in the project, is there a way to get the file address of the source code? Or is there a better way to add a unique image icon to the app?
I have two classes. One is a game, and the other is a frame that displays an image. They are both on JFrames. I want to put the image onto my class that is a game, and I tried just putting the part that makes the image in the image class, but it will not let me use the JFrame from my other class, saying that it doesn't exist. How do I make them recognize each other? Here is my code
The serializable class ImagePanel does not declare a static final serialVersionUID field of type long public class ImagePanel extends JPanel{ ^^^^^^^ ^ ^^2 problems (1 error, 1 warning) mh_sh_highlight_all('java');
im basically just trying to put the image inside the GUI and centre the text underneath it. Which is hard to believe since the text is above the image in the code .
I want to import an image to resize but not sure how to start of.Should I be using the "BufferedImage & ImageIO.read" method or the "paint(Graphics g) { Image img1 = Toolkit.getDefaultToolkit().getImage" method?
I'm trying to flip an image horizontally. However because when I flip the images they're offset by a bit, I added "-height" to offset the change in position. Unfortunately, it doesn't seem to be working 100% of the time; some images are adjusted to their correct position but some are not.I'm using this line to flip an image: Java Code: g.drawImage(castle, x, y - height, -width, height, null); mh_sh_highlight_all('java');
I am very much new to Java. I have just started learning event handling. Currently I am learning about Key Events. And am learning by doing. Well that is how one could learn anything in fact. I want to write a program in which the currently loaded image in the panel of a frame changes upon a key press say "Enter" or any other key.
How do random text in an image ? Let me explain : I have ten identical pictures and want randomly appear different words in each image. This is possible to do?
1. The human user of my application asks it to fire up a scanner which scans a paper document. The document is a filled in form. 2. The application then displays the scanned image to the human user.The image is displayed in a JScrollPane since it may be larger than the scroll pane. 3. The human user needs to locate a certain item in the form, for example a social security number, and enter it into a field in a data entry screen.Note that the image and the field appear on the same screen.
Of-course the social security number always appears in the same location in the image. Also the image needs to be the appropriate magnification and resolution to allow the human user to easily read and understand the item he is searching for in the image.
What is the best way to present the scanned image to the user such that he immediately sees the item he requires and can enter it into the data entry field.
What I am trying to do is save the the content drawn to my screen as an image. The following code is my render method and although I know how to use it, I don't fully understand the classes and how they work with is making this difficult.
public void render() { BufferStrategy bs = this.getBufferStrategy(); if (bs == null) { createBufferStrategy(3); return;
