How to save image which is inside an applet?

In my web application, I am displaying some graphs using applet. I wish to let the user save the graphs as images from the browser.
I would really appreciate if somebody could inform me about this.
Thanks
Sachin

A couple of things...
1) You will need to sign your applet afterwards, otherwise the user will not be able to save the graphic to their hard drive due to the Java security policy.
2) I did something similar, a code snippet is below. Mine was a Servlet version though, and sent the buffered stream to a JSP page where it was displayed as a graphic. You can figure out how to modify this so that it goes to a File stream instead... You will
OutputStream stream;
BufferedImage bi = new BufferedImage(pieValueObject.getCanvasWidth(), pieValueObject.getCanvasHeight(),
BufferedImage.TYPE_BYTE_INDEXED);
Graphics2D graphics = (Graphics2D)bi.createGraphics();
// paint all your stuff on the graphics object created above
// use a JPEG encoder to actually take what is on the graphics
// object inside the BufferedImage, and encode it to the stream.
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(stream);
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bi);
param.setQuality(1.0f, false);
encoder.setJPEGEncodeParam(param);
encoder.encode(bi);
// Your graphic is now in the Output stream.

How to reference an image which is inside of ArrayList?

Hi,
I have an item renderer which displays an image.

i want to renew my window and how to save backups which i hav on my itunes ??

See Backup your iTunes for Windows library with SyncToy. As long as you copy your entire library over to the new/rebuilt computer your devices should sync with the library and will be backed up on the first sync. If you really want to backup the device backups see this support document iTunes: About iOS backups and backup the device backup folders, then restore them into your new profile.

How to Save image in a text to my photos

How do I save the photo in a text message to my iPad air photos?

Tap the image in Message. (If you touch too long it brings up the: Copy; Other... menu instead)
This blows the image up to full screen.
Touch the image again to get menu options.
In the top right corner, tap the box with the up arrow. One choice is Save Image. Touch it to save to your camera roll.
In the top left corner, the three-line menu shows you all the photos in the message string, and some metadata like image size and camera title/image number.
This is in IOS 7.1.1 on an iPad, and should work on iPhone and Touch also.

1.Go to transaction SE78.
2.Select tree menu: Form Graphics -> Stroed on Document Server -> Graphics General Graphics -> BMAP Bitmap Images
3.Select <IMPORT> to import bitmap image file to SAP. System will popup screen for input file information and target name.
4.Select <Tick> After you already input data. System will upload image and return message to tell you success or fail.
5.You can preview the picture that uploaded by select<print prv>
If u want to store the images and retrive it from the server corresponding to the person id then just save the image by person id and code it as per the requirement.
U can save ur images using se78 and also u can c it using TCODE AL11.By navigating thru the exact path u can get the images.

How to save Image from binding FlipView?

I bind 4 images in my FlipView, how save an binding Image to Picture Library;
<FlipView Name="display1" ItemsSource="{Binding}" Foreground="#FFE6D52E" HorizontalAlignment="Center" VerticalAlignment="Center
            <FlipView.ItemTemplate>
                <DataTemplate>
                            <Image x:Name="image" Source="{Binding Path=Image}" Stretch="UniformToFill"/>

//for me it is hard to save binding files,I cant save any image

Hi Icce cage,
Per my understanding, you bind the path of image to Image control, so you get image path string from display1.SelectItem property. Try finding Image from this path in installation folder and then copy it to Picture library. Please try the following code
snippet.
Custom class to hold the image object.
public class CustomClass
public string ImagePath { get; set; }
public string ImageName { get; set; }
Initial image sources.
private void Page_Loaded(object sender, RoutedEventArgs e)
images = new System.Collections.ObjectModel.ObservableCollection<CustomClass>();
images.Add(new CustomClass() { ImagePath = "/Images/1.png", ImageName = "1.png" });
images.Add(new CustomClass() { ImagePath = "/Images/2.png", ImageName = "2.png" });
images.Add(new CustomClass() { ImagePath = "/Images/3.png", ImageName = "3.png" });
images.Add(new CustomClass() { ImagePath = "/Images/4.png", ImageName = "4.png" });
images.Add(new CustomClass() { ImagePath = "/Images/5.png", ImageName = "5.png" });
display1.ItemsSource = images;
XAML.
<FlipView RightTapped="display1_RightTapped" Name="display1" Foreground="#FFE6D52E" HorizontalAlignment="Center" VerticalAlignment="Center" >
<FlipView.ItemTemplate>
<DataTemplate>
<Image x:Name="image" Source="{Binding Path=ImagePath}" Stretch="UniformToFill"/>
</DataTemplate>
</FlipView.ItemTemplate>
</FlipView>
Save image to picture library.
private async void display1_RightTapped(object sender, RightTappedRoutedEventArgs e)
CustomClass data = display1.SelectedItem as CustomClass;
if (data!=null)
var installation = Windows.ApplicationModel.Package.Current.InstalledLocation;
var imagesfolder =await installation.GetFolderAsync("Images");
var file = await imagesfolder.GetFileAsync(data.ImageName);
await file.CopyAsync(KnownFolders.PicturesLibrary);

How to "Save Image" directly instead of "Save Image As"?

Is there anyway or option to directly save images instead of having to click "save image as" then go into the popup to save the image location? Thank you!

Gingerbread Man made good suggestions.
However you still must "save as" something even if "unnamed001". Windows requires a name and location for each file (whether an image or other file) saved. You can have the same file name in different directories (folders).
You can copy and paste images without saving, in some applications.

How to save image from email to iPhoto

trying to save image attachment from email to iPhoto

What is the problem? What does not work?
Either drag the attachment from the mail to the iPhoto con in the Dock, or ctrl-click the attachment and use the option "Export to iPhoto" from the pop-up menu (in Mail in MacOS X 10.10). Don't remember, if this worked in Mail in Mac OS X (10.5.8), as your signature is showing.

Problem with how FeuerFuchs saves images

FeuerFuchs presently seems to work like this. You load a page displaying an image or images. You like one or more of them and you want to save them. Each time you tell FeuerFuchs to save an image, instead of copying that image from wherever it's stored in order to display it on your screen to the folder you want to save it to, FeuerFuchs re-downloads that image.
Can someone please tell me why FeuerFuchs is programmed to re-download images it's told to save instead of copying them from wherever they're stored in order to display it on the screen? It seems like that only serves to increase bandwidth usage.

I've got that and it's great for if I want to save all the images from one or more tabs. But it only saves images from entire tabs instead of one out of several images in a tab and the treeview navigation is slower than using the shortcuts I use to jump from one folder to the next.

How to save image?

Hi all,
I have drawn an Image using Graphics, and then I have drawn some rectangles on it.
How can I save that image with drawn rectangles?
any idea or link which should I refer?

Example 1:
import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Font;
import java.awt.FontMetrics;
import java.awt.GradientPaint;
import java.awt.Graphics2D;
import java.awt.geom.Ellipse2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
public class WriteImageType {
static public void main(String args[]) throws Exception {
    try {
      int width = 200, height = 200;
      // TYPE_INT_ARGB specifies the image format: 8-bit RGBA packed
      // into integer pixels
      BufferedImage bi = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
      Graphics2D ig2 = bi.createGraphics();
      Font font = new Font("TimesRoman", Font.BOLD, 20);
      ig2.setFont(font);
      String message = "www.java2s.com!";
      FontMetrics fontMetrics = ig2.getFontMetrics();
      int stringWidth = fontMetrics.stringWidth(message);
      int stringHeight = fontMetrics.getAscent();
      ig2.setPaint(Color.black);
      ig2.drawString(message, (width - stringWidth) / 2, height / 2 + stringHeight / 4);
      ImageIO.write(bi, "PNG", new File("c:\\yourImageName.PNG"));
      ImageIO.write(bi, "JPEG", new File("c:\\yourImageName.JPG"));
      ImageIO.write(bi, "gif", new File("c:\\yourImageName.GIF"));
      ImageIO.write(bi, "BMP", new File("c:\\yourImageName.BMP"));
    } catch (IOException ie) {
      ie.printStackTrace();
Example 2:
// Create an image to save
    RenderedImage rendImage = myCreateImage();
    // Write generated image to a file
    try {
        // Save as PNG
        File file = new File("newimage.png");
        ImageIO.write(rendImage, "png", file);
        // Save as JPEG
        file = new File("newimage.jpg");
        ImageIO.write(rendImage, "jpg", file);
    } catch (IOException e) {
    // Returns a generated image.
    public RenderedImage myCreateImage() {
        int width = 100;
        int height = 100;
        // Create a buffered image in which to draw
        BufferedImage bufferedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
        // Create a graphics contents on the buffered image
        Graphics2D g2d = bufferedImage.createGraphics();
        // Draw graphics
        g2d.setColor(Color.white);
        g2d.fillRect(0, 0, width, height);
        g2d.setColor(Color.black);
        g2d.fillOval(0, 0, width, height);
        // Graphics context no longer needed so dispose it
        g2d.dispose();
        return bufferedImage;
    }
