I am trying to add images to a rtf document. I am able to add images to the document but I can't append any images. This means that when the 2nd Image is added, the first image is removed. I think that whenever the code is executed a new rtf document is created.
public class InsertToWord {
com.lowagie.text.Document doc = null;
FileOutputStream evidenceDocument;
String fileName = "evidenceDocument.rtf";
settings obj = null;
InsertToWord() {
obj = new settings();
doc = new com.lowagie.text.Document();
}
public void insertImage(File saveLocation) {
try {
evidenceDocument = new FileOutputStream(obj.getFileLocation() + fileName);
RtfWriter2.getInstance(doc, evidenceDocument);
doc.open();
com.lowagie.text.Image image = com.lowagie.text.Image.getInstance(saveLocation.toString());
image.scaleAbsolute(400, 300);
doc.add(image);
doc.close();
} catch (Exception e) {
}
}
}
On your insertImage() method, you are indeed creating a new file and overwriting your old one.
This line is creating the new file:
evidenceDocument = new FileOutputStream(obj.getFileLocation()+fileName);
You can pass the FileOutputStream in as a parameter to the method and then remove the line all together:
public void insertImage( FileOutputStream evidenceDocument , File saveLocation )
This code is the one I´m using to add an image into a RTF format and its working fine :
public void actionPerformed(ActionEvent arg0) {
JFileChooser fileChooser = new JFileChooser();
int option = fileChooser.showOpenDialog(null);
File file = fileChooser.getSelectedFile();
if (option == JFileChooser.APPROVE_OPTION) {
try {
BufferedImage image = ImageIO.read(file);
image = Scalr.resize(image, 200);
document = (StyledDocument) textPane.getDocument();
javax.swing.text.Style style = document.addStyle("StyleName", null);
StyleConstants.setIcon(style, new ImageIcon(image));
document.insertString(document.getLength(), "ignored text", style);
}
catch (Exception e) {
e.printStackTrace();
}
}
if (option == JFileChooser.CANCEL_OPTION) {
fileChooser.setVisible(false);
}
}// End of Method
The textPane variable is a JTextPane.

So im trying to save a image (Image class from javafx.scene.image.Image) onto a file with a save file dialog (JFileChooser) so that it is user friendly.
What i want it to do: Save the image specified
What it does: Save dialog works (i think), and it doesn't save (write to file) anything.
Here is the code behind it:
public void saveFile() { //menu item interface for save and save as
JFrame parentFrame = new JFrame();
JFileChooser fileChooser = new JFileChooser();
fileChooser.setDialogTitle("Save");
fileChooser.setCurrentDirectory(new File(System.getProperty("user.home")));
//Setting the file extentions
/*fileChooser.addChoosableFileFilter(new FileNameExtensionFilter("PNG Image", ".png"));
fileChooser.addChoosableFileFilter(new FileNameExtensionFilter("JPG Image", ".jpg"));
fileChooser.addChoosableFileFilter(new FileNameExtensionFilter("BMP Image", ".bmp"));*/
int userSelection = fileChooser.showSaveDialog(parentFrame);
if (userSelection == JFileChooser.APPROVE_OPTION) {
File fileToSave = fileChooser.getSelectedFile(); //selected file
saveToFile(picFrame.getImage(), fileToSave); //save the file
System.out.println("Save as file: " + fileToSave.getAbsolutePath()); //debug because it doesnt work
}
parentFrame.dispose();
}
and here is saveToFile
public static void saveToFile(Image image, File file) {
String extension = "";
File outputFile = file;
try {
if (file != null && file.exists()) {
String name = file.getName();
extension = name.substring(name.lastIndexOf("."));
}
} catch (Exception e) {
extension = "";
}
BufferedImage bImage = SwingFXUtils.fromFXImage(image, null);
try {
ImageIO.write(bImage, extension, outputFile);
System.out.println("Saveing file");
} catch (IOException e) {
throw new RuntimeException(e);
}
}
After some digging arround and debuging i found the problem and the solution , so here it is.
All the code.
public void saveFile() { //menu item interface for save and save as
Window mainStage = ap.getScene().getWindow(); //get ze window
FileChooser fileChooser = new FileChooser(); //Filechooser the class that has the file chooser
fileChooser.setTitle("Open Resource File"); //Title of prompt
fileChooser.getExtensionFilters().addAll( //add filter
new ExtensionFilter("Image Files", "*.png", "*.jpg", "*.gif", ".bmp"), //Filters
new ExtensionFilter("All Files", "*.*")); //Filters
File selectedFile = fileChooser.showSaveDialog(mainStage); //get the file
if (selectedFile != null) { //if something is selected then
System.out.println(selectedFile.getAbsoluteFile()); //debug
System.out.println(selectedFile.getAbsoluteFile().getParent()); //debug
Image img = SwingFXUtils.toFXImage(bImg, null); //convert to Image
saveToFile(img, selectedFile); //save the Image
}
}
/**
* A simple image save
*
* #param image The image you want to save
* #param file The file where you want to save it
*/
public static void saveToFile(Image image, File file) {
File outputFile = file; //file
BufferedImage bImage = SwingFXUtils.fromFXImage(image, null); //Convert to bufferedimage
try {
ImageIO.write(bImage, getFileExtension(outputFile).toUpperCase(), outputFile.getAbsoluteFile()); //actualy save
System.out.println("Saveing file ex: " + getFileExtension(outputFile).toUpperCase() + " to: " + outputFile.getAbsoluteFile() + " with name " + outputFile.getName());
} catch (IOException e) {
throw new RuntimeException(e);
}
}
private static String getFileExtension(File file) {
String name = file.getName();
int lastIndexOf = name.lastIndexOf(".") + 1;
if (lastIndexOf == -1) {
return ""; // empty extension
}
return name.substring(lastIndexOf);
}
I have two buttons in a menubar that contains both a save and save as button. However, I currently have the code for both of them the same and it does the save as currently with prompting the user where they want to save. I want the save button to only save without prompting for the dialog unless the file doesn't yet exist.
I've tried fiddling around with the code to try and figure out a workaround, but have not figure it out.
fileMenu.getItems().add(saveItem);
saveItem.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
FileChooser saveFile = new FileChooser();
saveFile.getExtensionFilters().add(new FileChooser.ExtensionFilter("Image Files", "*.png", "*.jpg"));
saveFile.setTitle("Save File");
File file = saveFile.showSaveDialog(stage);
if (file != null) {
try {
WritableImage writableImage = new WritableImage(width, height);
canvas.snapshot(null, writableImage);
RenderedImage renderedImage = SwingFXUtils.fromFXImage(writableImage, null);
ImageIO.write(renderedImage, "png", file);
} catch (IOException ex) {
System.out.println("Error");
}
}
}
});
fileMenu.getItems().add(saveAsItem);
saveAsItem.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
FileChooser saveFile = new FileChooser();
saveFile.getExtensionFilters().add(new FileChooser.ExtensionFilter("Image Files", "*.png", "*.jpg"));
saveFile.setTitle("Save File");
File file = saveFile.showSaveDialog(stage);
if (file != null) {
try {
WritableImage writableImage = new WritableImage(width, height);
canvas.snapshot(null, writableImage);
RenderedImage renderedImage = SwingFXUtils.fromFXImage(writableImage, null);
ImageIO.write(renderedImage, "png", file);
} catch (IOException ex) {
System.out.println("Error");
}
}
}
});
The code currently does the exact same save function for each save button. I want it to only prompt for the save as button.
You need to have a File instance field in your class that is initially assigned to null. When you read in a File or when you do your first save, then this field is assigned to that File. When the save button is pressed, then you check if the field is null, and if so, show the dialog as you would for the save-as button. If the field is not null, then you simply write the file to disk using the data that you have and that File.
for example (code not tested):
// a private instance field
private File myFile = null;
fileMenu.getItems().add(saveItem);
saveItem.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
if (myFile == null) {
saveAs();
} else {
writeFile(myFile);
}
}
});
fileMenu.getItems().add(saveAsItem);
saveAsItem.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent event) {
saveAs();
}
});
private void writeFile(File file) {
if (file != null) {
try {
WritableImage writableImage = new WritableImage(width, height);
canvas.snapshot(null, writableImage);
RenderedImage renderedImage = SwingFXUtils.fromFXImage(writableImage, null);
ImageIO.write(renderedImage, "png", file);
} catch (IOException ex) {
System.out.println("Error");
}
}
}
private void saveAs() {
FileChooser saveFile = new FileChooser();
saveFile.getExtensionFilters().add(new FileChooser.ExtensionFilter("Image Files", "*.png", "*.jpg"));
saveFile.setTitle("Save File");
File file = saveFile.showSaveDialog(stage);
myFile = file; // !!
writeFile(file);
}
So am trying to make a button where it opens a FileChoser to import an image .
My probleme is :
1-I want the fileChoser to display only images-files(.jpg ...).
2-When the FileOpener opens , the other windows should be Disabled until the
FileOpener is disposed . In my case , they are disabled but when I click on them my programe crashes for some reason .
3-If there is a better FileOpener it will be welcomed , this si not mine I found it on the net .
Here's my source code :
public class FileOpener {
private JFileChooser file_chooser = new JFileChooser();
StringBuilder path = new StringBuilder();
public File choosed() {
File file = null;
if(file_chooser.showOpenDialog(null) == JFileChooser.APPROVE_OPTION) {
file = file_chooser.getSelectedFile();
Scanner input = null;
try {
input = new Scanner(file);
} catch (FileNotFoundException e) {
System.out.println("Fail");
e.printStackTrace();;
}
while(input.hasNext()) {
path.append(input.nextLine());
}
input.close();
}
return file;
}
public String getPath() {
return path.toString();
}
}
And here's my call (Where there is a probleme is the enable-disable window) :
Button button_2 = new Button(composite_1, SWT.FLAT);
button_2.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
shell.setEnabled(false);
FileOpener v = new FileOpener();
File file = v.choosed();
if(file != null) {
Image image = new Image(shell.getDisplay(), file.getPath());
Image image2 = main.ScaleImage(image, Image_input);
Image_input.setImage(image2);
}
shell.setEnabled(true);
}
});
Notice that this code works , but am trying just to fix the bugs,the "ScaleImage" fonction reScale the chosen Image to fit my label.
I managed to fix the Enable-disable problem simply by removing all what was interfering with the shell :
Button button_2 = new Button(composite_1, SWT.FLAT);
button_2.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
FileOpener v = new FileOpener();
File file = v.choosed();
shell.forceActive();
if(file != null) {
Image image = new Image(shell.getDisplay(), file.getPath());
Image image2 = main.ScaleImage(image, Image_input);
Image_input.setImage(image2);
}
}
});
I fixed completly my probleme by using FileDialog :
Button button_2 = new Button(composite_1, SWT.FLAT);
button_2.addSelectionListener(new SelectionAdapter() {
#Override
public void widgetSelected(SelectionEvent e) {
FileDialog test = new FileDialog(shell);
test.open();
File file = new File(test.getFilterPath()+"\\"+test.getFileName());
if(file != null) {
Image image = new Image(shell.getDisplay(), file.getPath());
Image image2 = main.ScaleImage(image, Image_input);
Image_input.setImage(image2);
}
}
});
Thanks for greg-449 for the answer .I didn't know how to exactly work with the new GUI but to get the file path :
test.getFilterPath()+"\\"+test.getFileName()
I have a JPanel name "imagePanel" and a button name "browseBtn". All contained in a JFrame class. When pressing the browseBtn, a file chooser will open up and after choosing a PNG image file, the image will appear directly in the imagePanel.
This is the action event for the browseBtn
private void browseBtnActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
JFileChooser fc = new JFileChooser();
int result = fc.showOpenDialog(null);
if (result == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
if (accept(file)) {
try {
ImageIcon image = new ImageIcon(file.getPath());
JLabel l = new JLabel(image);
imagePanel.add(l);
} catch (Exception e) {
JOptionPane.showMessageDialog(this, "Error reading file !");
}
}
else {
JOptionPane.showMessageDialog(this, "Choose png file only !");
}
}
}
public boolean accept(File file) {
return file.isDirectory() || file.getAbsolutePath().endsWith(".png");
}
I have choose the correct .png file but i don't understand why the image didn't show up in the imagePanel. Can you guy explain on that ?
Cheers.
You should avoid creating new objects everytime you want to display your image, imagine if you change it 5 times, you're creating 5 times an object while you display only one !
Like said in the comments, your best shot would be to create your label when you create your panel, add it to said panel, then simply change the icon of this label when you load your image.
browseBtn.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
JFileChooser fc = new JFileChooser();
int result = fc.showOpenDialog(null);
if (result == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
if (accept(file)) {
try {
ImageIcon image = new ImageIcon(file.getPath());
label.setIcon(image);
} catch (Exception ex) {
JOptionPane.showMessageDialog(this, "Error reading file !");
}
}
else {
JOptionPane.showMessageDialog(this, "Choose png file only !");
}
}
}
public boolean accept(File file) {
return file.isDirectory() || file.getAbsolutePath().endsWith(".png");
}
});
Assuming label is the reference to said JLabel, created on components initialisation.
Or you might try this :
browseBtn.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
JFileChooser fc = new JFileChooser();
int result = fc.showOpenDialog(null);
if (result == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
if (accept(file)) {
try {
ImageIcon imageIcon = new ImageIcon(new ImageIcon(file.getPath()).getImage().getScaledInstance(20, 20, Image.SCALE_DEFAULT)); //resizing
label.setIcon(imageIcon);
/*try { // or try this
InputStream inStream = this.getClass().getClassLoader().getResourceAsStream(file.getPath());
BufferedImage img = ImageIO.read(inStream);
Image rimg = img.getScaledInstance(width, height, Image.SCALE_STANDARD);
label.setIcon(rimg);
} catch (IOException e) {}*/
} catch (Exception ex) {JOptionPane.showMessageDialog(this, "Error reading file !");}
} else {JOptionPane.showMessageDialog(this, "Choose png file only !");}
}
}
public boolean accept(File file) {
return file.isDirectory() || file.getAbsolutePath().endsWith(".png");
}
});
i have the following code trying to save the contents of a JTextPane as RTF. although a file is created in the following code but it is empty!
any tips regarding what am i doing wrong? (as usual dont forget im a beginner!)
if (option == JFileChooser.APPROVE_OPTION) {
////////////////////////////////////////////////////////////////////////
//System.out.println(chooser.getSelectedFile().getName());
//System.out.println(chooser.getSelectedFile().getAbsoluteFile());
///////////////////////////////////////////////////////////////////////////
StyledDocument doc = (StyledDocument)textPaneHistory.getDocument();
RTFEditorKit kit = new RTFEditorKit();
BufferedOutputStream out;
try {
out = new BufferedOutputStream(new FileOutputStream(chooser.getSelectedFile().getName()));
kit.write(out, doc, doc.getStartPosition().getOffset(), doc.getLength());
} catch (FileNotFoundException e) {
} catch (IOException e){
} catch (BadLocationException e){
}
}
EDIT: HTMLEditorKit if i use HTMLEditorKit it works and thats what i really wanted. SOLVED!
if (textPaneHistory.getText().length() > 0){
JFileChooser chooser = new JFileChooser();
chooser.setMultiSelectionEnabled(false);
int option = chooser.showSaveDialog(ChatGUI.this);
if (option == JFileChooser.APPROVE_OPTION) {
StyledDocument doc = (StyledDocument)textPaneHistory.getDocument();
HTMLEditorKit kit = new HTMLEditorKit();
BufferedOutputStream out;
try {
out = new BufferedOutputStream(new FileOutputStream(chooser.getSelectedFile().getAbsoluteFile()));
kit.write(out, doc, doc.getStartPosition().getOffset(), doc.getLength());
} catch (FileNotFoundException e) {
} catch (IOException e){
} catch (BadLocationException e){
}
}
}
here is the solution. it works if HTMLEditorKit is used.
Here is a solution for RTF and not HTML.
As RTF is not standardized, I needed some additional tags like \sb and \sa to force my Wordpad to display the file properly.
protected void exportToRtf() throws IOException, BadLocationException {
final StringWriter out = new StringWriter();
Document doc = textPane.getDocument();
RTFEditorKit kit = new RTFEditorKit();
kit.write(out, doc, doc.getStartPosition().getOffset(), doc.getLength());
out.close();
String rtfContent = out.toString();
{
// replace "Monospaced" by a well-known monospace font
rtfContent = rtfContent.replaceAll("Monospaced", "Courier New");
final StringBuffer rtfContentBuffer = new StringBuffer(rtfContent);
final int endProlog = rtfContentBuffer.indexOf("\n\n");
// set a good Line Space and no Space Before or Space After each paragraph
rtfContentBuffer.insert(endProlog, "\n\\sl240");
rtfContentBuffer.insert(endProlog, "\n\\sb0\\sa0");
rtfContent = rtfContentBuffer.toString();
}
final File file = new File("c:\\temp\\test.rtf");
final FileOutputStream fos = new FileOutputStream(file);
fos.write(rtfContent.toString().getBytes());
fos.close();
}
This is how I did when I faced the same problem.
public void actionPerformed(ActionEvent e) {
text = textPane.getText();
JFileChooser saveFile = new JFileChooser();
int option = saveFile.showSaveDialog(null);
saveFile.setDialogTitle("Save the file...");
if (option == JFileChooser.APPROVE_OPTION) {
File file = saveFile.getSelectedFile();
if (!file.exists()) {
try {
BufferedWriter writer = new BufferedWriter(
new FileWriter(file.getAbsolutePath() + ".rtf"));
writer.write(text);
writer.close();
} catch (IOException ex) {
ex.printStackTrace();
System.out.println(ex.getMessage());
JOptionPane.showMessageDialog(null,
"Failed to save the file");
}
}
else if (file.exists()) {
int confirm = JOptionPane.showConfirmDialog(null,
"File exists do you want to save anyway?");
if (confirm == 0) {
try {
BufferedWriter writer = new BufferedWriter(
new FileWriter(file.getAbsolutePath()
+ ".rtf"));
writer.write(text);
writer.close();
} catch (IOException ex) {
ex.printStackTrace();
System.out.println(ex.getMessage());
JOptionPane.showMessageDialog(null,
"Failed to save the file");
}
}
else if (confirm == 1) {
JOptionPane.showMessageDialog(null,
"The file was not saved.");
}
}
}
if (option == JFileChooser.CANCEL_OPTION) {
saveFile.setVisible(false);
}
}// End of method
The only problem I've seen in your code is that you're not closing the output stream (when content is actually written to disk).
Try out.close().
It should solve your problem.
