How to save contents in paintbox to .jpeg or any image file using Director?

I'm having difficulty in our System using Director (THESIS) because one of the compilation we had is to save the drawings in the paintbox into an image file (.jpeg, .bmp, .png, etc). Is there someone who can help me? Please I really need to learn it before deploying the final System. Thanks much~

How to save or save a drawing in a PNG or any Image file format ?

Hi,
I am working on a signature capturing application using J2ME MIDP 2.0 for Palm Treo 750 with Windows Mobile 6.0
I am taking signatures as a drawing on a CustomItem.
Now, i want to send it to a php script running on Apache server to save this signature as a PNG, jpeg or any image file at server end.
or how can i save this drawing on my local file system as a png or any other type of image file.
Plz help if anybody knows the right way....
Thanks.

Hi Hithayath,
Thnx for the reply.
Actually, i hv no problem in storing a data locally or sending it on a web server. The problem in related with the formats.
I mean, how can we create a png or jpg file using the raw bytes of an image drawn on a canvas or CustomItem.. ?
We can get the integer array of RGB points using getRGB() method of image object. Now, if i will write this data after converting to binary in a file then that file
will show a message like "Preview not available". It means the format is not recognized.
So, my question is how can we convert this raw data in a png or jpg format so it can be displayed on a web page or stored in a png or jpg file..?
I think now u can better understand the problem.
Waiting for the reply....
Thanks. :)

How to save content of JPanel into jpeg or png file

I have to independent classes: Class A and Class B. Each class constructs its own graphical objects:
Class A {
//do something
public void paintComponent(Graphics g)
int x = 0;
int y = 0;
int w = getSize().width;
int h = getSize().height;
bi = new BufferedImage(
w,h,100,BufferedImage.TYPE_INT_RGB);
g2d = bi.createGraphics();
// draw lines
g2d.drawImage(bi,0,0,ww,hh, this);
Class B {
int x = 0;
int y = 0;
int w = getSize().width;
int h = getSize().height;
bi = new BufferedImage(
w,h,100,BufferedImage.TYPE_INT_RGB);
g2d = bi.createGraphics();
// draw lines
g2d.drawImage(bi,0,0,ww,hh, this);
Two buffered images get properly displayed within JPanel component. However, I need to save two those results into one file. If I add saving file routine into every class, at best I can only get them to be in two different files.
Please let me know if anyone can help me with this problem.
Thanks,
Jack

You didn't mention what should be the format of file that the combines the images. Here are two options:
1. Create another BufferedImage, and draw the BufferedImages from class A and B over this BufferedImage and save it as JPEG or PNG.
In each of the class, you can add a method like getBufferedImage(), which would return the local BufferedImage. A third class, say class C, needs to call this method in each of the classes, and then draw the BufferedImages returned by these methods over another BufferedImage. Save this BufferedImage as a JPEG or PNG.
A disadvantage of this approach is that you can't easily retrieve the individual images from the resulting file.
2. Create a single zip file by adding the individual JPEG/ PNG images created from the BufferedImage in class A and B.
Here is an example that creates single zip file of JPEG images from an array of BufferedImageObjects:
public static void zip(String outfile, BufferedImage bufimage[]){
 if(bufimage == null) return;
 try{
 File of = outfile.endsWith(".zip")? new File(outfile): new File(outfile+".zip");
 FileOutputStream fos = new FileOutputStream(of);
 ZipOutputStream zos = new ZipOutputStream(fos);
 for(int i=0;i<bufimage.length;i++){
 try{
 ByteArrayOutputStream boutstream = new ByteArrayOutputStream();
 JPEGImageEncoder enc = JPEGCodec.createJPEGEncoder(boutstream);
 enc.encode(bufimage);
ZipEntry entry = new ZipEntry("bufimage"+(new Integer(i)).toString()+".jpg");
entry.setMethod(ZipEntry.DEFLATED);
zos.putNextEntry(entry);
byte[] fileBuf = boutstream.toByteArray();
zos.write(fileBuf,0,fileBuf.length);
zos.closeEntry();
} catch (Exception e){ e.printStackTrace();}
zos.flush();
zos.close();
}catch(Exception e) {e.printStackTrace();}
The above method uses the JPEG codec and the zip package, both of which available in J2SE. In other words, you need to import com.sun.image.codec.jpeg and java.util.zip packages.
With this approach, you can easily retrieve the individual JPEGs using the java.util.zip package.

How to save content of a whole swing page

Hi everyone ..
can any of u tell me ,how to save contents of a java swing page in a single file with all components viz . textfield,textarea,JTable,JPanel etc .. with their respective formatting ie.e Font,Color etc ..
Plz let me know it soon .. its very urgent ..
Can I save it as Screenshot or Jpeg Image .. or how to go about it .

Sure: see below!
WARNING: this code will not compile as is because it uses some other classes from my personal code library (FileUtil & StringUtil). The particular methods of those classes which are used below are trivial methods that anyone can write, which is is why I have not posted them as well. So, to get the code below to compile, you can
a) write your own versions of these classes or
b) simply add the necessary methods to this class or
c) simply comment out their usage (in the case of StringUtil, which is just used for arg checking)
But if you still want me to post them, then I can post the relevant fragments of those classes.

* Class which supports taking screen shots of the entire desktop, AWT Components, or Swing JComponents.
* This functionality is implemented in a series of <code>take</code> methods, each of which returns a BufferedImage.
* This class also offers convenience <code>write</code> methods for storing BufferedImages to files.
* 
* The images taken by this class should be the precise images seen on the screen.
* However, the images written to files may deviate from the originals.
* One obvious cause is limitations of the chosen file format (especially with lossy formats like jpeg).
* A subtle issue can occur, however, even when using lossless formats like png:
* if the file is subsequently opened by another application,
* that application may rescale the image, which can often cause visible artifacts.
* <blockquote>
* To see this last problem on Windows XP,
* call {@link #take()} which returns an image of the entire desktop and write it to a file,
* and then open the file with XP's default graphics file viewer ("Windows Picture And Fax Viewer").
* This program shrinks the desktop image in order to fit it inside the program's window,
* and rescaling artifacts are readily seen, especially if the desktop image has any kind of text in it.
* If "Windows Picture And Fax Viewer" instead cropped the image or had a scroll pane, then this should not happen.
* </blockquote>
* 
* Acknowledgement: this class was inspired by the program
* <a href="http://www.discoverteenergy.com/files/ScreenImage.java">ScreenImage</a>.
* Differences from the above program:
* <ol>
* <li>this class uses {@link BufferedImage#TYPE_INT_ARGB} instead of {@link BufferedImage#TYPE_INT_RGB} in order to preserve alpha</li>
* <li>this class's {@link #formatNameDefault default image file format} is PNG instead of JPEG</li>
* <li>this class's <code>take</code> methods simply take snapshots and never have the side effect of writing image files</li>
* <li>this class added a version of <code>take</code> which can get a snapshot of a region of a Component</li>
* <li>
* when taking a snapshot of a region of a Component or JComponent,
* the Rectangle that specifies the region always has coordinates relative to the origin of the item
* </li>
* </ol>

* 
* It might appear that this class is multithread safe
* because it is immutable (both its immediate state, as well as the deep state of its fields).
* However, typical Java gui code is not multithread safe, in particular, once a component has been realized
* it should only be accessed by the event dispatch thread
* (see <a href="http://java.sun.com/developer/JDCTechTips/2003/tt1208.html#1">Multithreading In Swing</a>
* and <a href="http://java.sun.com/developer/JDCTechTips/2004/tt0611.html#1">More Multithreading In Swing</a>).
* So, in order to enforce that requirement, all methods of this class which deal with components
* require the calling thread to be the event dispatch thread.
* See the javadocs of each method for its thread requirements.

How to save content typed in textfield only as lowercase in repository?

How to save content typed in textfield only as lowercase in repository?
Suppose we have a textfield in a component dialog. Irrespective of how enduser enters the data in the textfield, lower/mixed/upper case, it should always be saved as lowercase in the repository.

You have 2 options:
* Frontend: You adjust the javascript, so the user can only enter lowercase characters
* Server-side: Implement a SlingPostProcessor to change the data to lowercase before it is persisted (see http://sling.apache.org/apidocs/sling6/org/apache/sling/servlets/post/SlingPostProcessor.h tml)

Hi,
Yes, you need store data to table, and fetch it when page is opened.
Simple way is create table with few columns and e.g. with CLOB column and then create form based on that table.
Then modify item types as you like, e.g. use HTML editor for CLOB column

How stop PS6 from removing the DPI value from an image when using "save for the web"?

How stop PS6 from removing the DPI-value from an image when using "save for the web"?
Example:
- Open a tif image, that contains a dpi value (resolution).
- Use the splice tool in PS6.
- Export the slices with "Save for web", as gif-files.
Then the dpi value is removed, the gif files has no dpi value (it's empty).
How can we stop PS6 from removing the dpi value when using "save for web"?
OR:
When using the slice tool, how can we save the sliced pieces without PS removing the dpi value?

you can make your art go a little bit over the bounds. or you can make sure your artboart and art edges align to pixels

I am actually interested in extract the page and create a new PDF with that page. But still there is a catch that on which basis the page needs to extract either on PAGE number OR on Bookmark basis.
But here in this scenario assume I am looking for the PDF file, now I want to save only page 5. How can I extract page 5 automatically/programmatuically? Or in simple word how can I get the reference link of page 5?
Here I am not getting clear picture that Do I need both SDK Adobe & Acrobat to achieve this requirement. And more over you have mentioned that SDK itself is free. But on Adobe side it is mentioned that it is available by license only with this I have another doubt: To work my desktop/system application with Adobe PDF library, this library needs to distribute with the application. So in this case will it be chargeable for each and every deployment.
Could you please provide me the link from where I can download the SDK? So that I can do some excerise with SDK to figure out the exact flow of functionality to work with my application.

Nicola,
I am sorry but we do not have an example for "Save the Overlay Figures and Text in an Image File" for CVI. Currently, you are going to need to use Window's API calls in order to get this functionality.

How to save contents of JPanel to an image file

Hi,
I am using a JPanel to display some primitive shapes(line, circle,etc.) and I need to save the contents of this panel to disk as an image file (JPEG, bitmap, TIFF, etc.). Have searched jdc but've found no feasible results. I would really appreciate a sample code for this job.
Thanks in advance.

Got it ...i just forgot the 3rd line:
fos = new FileOutputStream("c:\\majjooo.jpg");
JPEGImageEncoder enc = JPEGCodec.createJPEGEncoder(fos);
enc.encode(img);but am still having a problem is that the picture is black ...eventhough the panel has contents and i can see it but the picture has nothing but pitch black ...what do you think ??

How to save the value in Cedit control into a text file bu using measurement studio c++?

Im using measurement studio c++ to create a application. How to save a randomly generated value which display in the CNumberEdit Control to a text file? how to do the coding part?

You can use the CNiFile class to write the value out to a file. For example, create a new Measurement Studio C++ project and follow these steps:
Add a CNiNumEdit to the dialog.
Add a member variable for the CNiNumEdit called m_numEdit.
Add a button to the dialog.
Double-click the button to add a message handler for the button's BN_CLICKED message.
Add the following code to the button's BN_CLICKED message handler:
CNiFile file("C:\\Values.log", CFile::modeCreate | CFile::modeWrite | CFile::typeText);
file << m_numEdit.Value << endl;
file.Close();
Run the application, edit the CNiNumEdit's value, and click the button. The value should be written to the Values.log
file as specified in the code above.
Hope this helps.

How to include Chart in Web Page not as seperate image file?

Hi, I am using JCharts and am trying to figure out how (or if it is even possible) to create a chart and then place it in a web page. All the examples I've seen show you how to create a JPEG of the chart and then link to this image from your web page. Is it not possible to surround the JPEG chart with other HTML so that I can keep my web page logo and menu etc on the same page as the chart?
I can't find any examples which show how to surround your images with HTML as JCharts creates a JPG file and returns that in the Http Response e.g. "ServletEncoderHelper.encodeJPEG13(axisChart, 1.0f, response);".
My environment is Java 1.4.2, Struts and Tomcat 4.1.30.
Is there a way of drawing charts directly into a web page rather than displaying them on a seperate page as an image file?
many thanks in advance,
James.

If you understand html, you know that to display an image, you must provide a reference to the image's location within the html code (there's no way to embed the image itself, directly in the html).
An image's reference is just an url of where the image can be loaded from. Provide an url which goes to your dynamic chart servlet and requests the appropriate chart (i.e., you may have to pass in certain parameters in the url).
