Bmp, gif, jpeg

[Tys Seyffert]

Hey all,

Is it possible to save a panel as a graphic file like a bmp, gif, jpeg?

I have a calender that has a panel as the base. I want to save the the calender as a graphic.

Thank you

Tys

If you're trying to save an image then you have to work with the image.Use the proper API. (See working with images on java.sun.com).

If you're trying to *print* a form, then i don't thing that there is a way you should do that, because this is an operating system's ability.I mean that in other languages, like C++,VB use some System's libraries (like MCI) to print a form etc. The reason is that the programming languages they can use such libraries, are written in system's code-base.And to be more specific: the operating system are written with these languages(talking for C++).Java is Platform Indepedent so i think what you're looking for can't be done.If there is a way to save a panel as an image without using system's libraries, post it if you'll find it, because i don't know any.Java is a low level to high level language,and probably there is a way, but i think it is very advanced.

I'm not telling you to stop looking, I'm telling you what i think.It is intresting , and if you find anything post it!

This could be buggy, I didn't test anything. Should give you the general idea though. Google's an amazing thing you know.

public void saveComponentAsJPEG(Component myComponent, String filename) {
       Dimension size = myComponent.getSize();
       BufferedImage myImage = 
         new BufferedImage(size.width, size.height,
         BufferedImage.TYPE_INT_RGB);
       Graphics2D g2 = myImage.createGraphics();
       myComponent.paint(g2);
       try {
         OutputStream out = new FileOutputStream(filename);
         JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
         encoder.encode(myImage);
         out.close();
       } catch (Exception e) {
         System.out.println(e); 
       }
     }

Um...Not exactly. Printing is a task performed by a Printer Driver. All printers are registered with the OS. It's the VM's job to locate those drivers and pass the information to them. That's why we have a different VM for different platforms.

Hi Gregg,
I believe at last, you are right!
But i think this could be difficult.I haven't try it.But this is true you posted.


Farewell!

It is difficult. The printing API sucks. But it's not much better in any otehr language. You really have to do a lot of preparations of whatever you are printing before sending it to the printer. Like making sure the margins are right and the print area is right, etc, etc. Someone needs to make a higher level API for this.
