Can Java support .bmp files?

This is probably a dumb question but I'm just wondering if Java supports .bmp files. I know how big they are and that they're not 100% reliable at being transparent and that they are slow when it comes to scaling. I also found them slow when they are drawn transparently not to mention that they are also not reliable at being translucent either. But I do have a program that can convert bitmaps to GIFs, JPEGs, PNGs, PCX... well, just about every image format that there is out there but I do start creating my images as .bmp's because they're easy to edit. So does Java support them?

I assume it does... If you're not sure, try it. But why the heck would you want to do that? BMP's are no easier to edit than PNG's, and PNG's are better than BMP's in every way. Using BMP's would be like shooting yourself in the foot. Also, when loading an image into memory, they don't work any differently than any other format. The only thing format affects is how the image works BEFORE it's loaded in. Once it's loaded, it's just another image. Different formats won't change the speed of working with them in Java.

Java support for file of large dimension

Hi friends,
Do you know if exist a support for managing file of large dimension (about 2GB) using java? BerkeleyDB could be a good support?
thanks

As Kaj mentioned before, using an NTFS partition, you should be able to write files of extreme sizes (for instance, an NTFS partition that is 200GB in size may store a single 200GB file).
Of course, using FileChannel objects, you shouldn't actually try and write the full 2+ GB of data at once, because that will effectively require over 2GB RAM for the data of your application alone. Instead, append your datafile one segment at a time (the size of the segment, in bytes, is roughly the amount of RAM you need for your data). Perhaps you can directly write the bytes into FileChannel (ie: when your measurements take place), which does not require a byte buffer.
Neither FileChannel nor File impose size restrictions beyond what the underlying operating system and type of partition impose. For example: a FAT32 partition can't deal with files over 4GB, so no language (Java, C++, whatever) will make it possible to store 4+ GB files on a FAT32 partition.
If you rewrite a portion of my [url http://forum.java.sun.com/thread.jsp?forum=31&thread=562837&start=15&range=15&hilite=false#2770450]sample from the thread "storing in Java", you should be able to write a 4GB file on your NTFS partition. Change the size of the byte buffer to 64MB and the amount of cycles to 64 and you're there.
I'm not sure how long it will take to write 64 chunks of 64MB, but don't expect it to finish in a few seconds. My regular IDE drive takes 2.25 seconds for a 60MB file (yet, my Serial-ATA drive does it in 1078ms, so don't forget that hardware has a significant impact on I/O performance as well).

Photoshop 7 can no open .bmp files?

Hi:
When I try to open a .bmp file using the PS7 file open method with the file dialog window set for all formats, no .bmp files appear in the list of files.
If in Windows Explorer a .bmp file is selected then the right click option of open with PS7 is used PS7 gives an error message.
I've read other posts about saving .bmp files in 8 bit mode but can find nothing in the forum or manual about opening a .bmp file.
How to do it?
Have Fun,
Brooke Clarke

-------SOLUTION------
Thanks to Ed pointing to the file BMP.8BI I've found the solution.
That file was missing from the folder at:
C:\Program Files\Adobe\Photoshop 7.0\Plug-Ins\Adobe Photoshop Only\File Formats
so PS7 could not work with .bmp files. The reason it was missing was an earlier version had a security bug. Adobe came out with a new version the top of the page looks like:
Photoshop CS2, Photoshop CS3 and Photoshop Elements 5 updates to address security vulnerabilities
Release date: July 10, 2007
Vulnerability identifier: APSB07-13
CVE number: CVE-2007-2244, CVE-2007-2365
Platform: All Platforms
Affected software versions: Photoshop CS2, Photoshop CS3, and Photoshop Elements 5.0
http://www.adobe.com/support/security/bulletins/apsb07-13.html
I downloaded the patch zip file for Photoshop Elements 5.0:
http://download.macromedia.com/pub/security/bulletins/apsb07-13/win/ps_security_update.zip
and after unziping it moved BMP.8BI into the File Formats folder and it seems to work fine in PS7.

Can Java execute batch file outside of current JVM in separate process tree

Hi,
Does anyone know how to run programs from Java as separate processes that will not die when the spawning java program exits (JVM exits).
The problem I have with using Runtime.exec is it spawns only child processes under the current running JVM, thus when the origonal program that called Runtime.exec ends so does all child processes.
Basically I want to start a DOS batch file from my Java application, my Java application will then immediately exit (calling System.exit(0) ). The batch program will continue to run, its does some file clean up, create's some new files and deletes the old jar (containing the main app), it then rebuilds the main app jar and and executes the main class and then exits itself.
I've also tried the apache.tomcat.jni.Proc :-
long pool = Pool.create( new Long(0).longValue() );
long pa = Procattr.create( pool );
Procattr.dirSet( pa, "c:\\temp\\updater\\");
Procattr.cmdtypeSet( pa, Proc.APR_SHELLCM );
Procattr.detachSet( pa, 1 );
long proc = Proc.alloc( pool );
Proc.create( proc, "test.bat", new String[]{"test.bat"}, null, pa, pool );
System.exit(0);
The detach option doesn't work, if I take it off then the bat file runs and stops the JVM exiting, if I leave it in the batch file never gets called.
Is this possible in Java. Can java start master process on Windows XP JDK1.5+?
Cheers
Chris.

Well I found the answer elsewhere (java.net) thought I'd post it here for future visitors who might be experience the same problem.
Basically Runtime can do this however it must be done the following way :-
The java:-
public class Main {
    public static void main(String[] args) throws Exception {
        Process p=Runtime.getRuntime().exec("cmd /c c:\\test.bat");
        System.out.println("done");
        System.out.println("quitting");
        System.exit(0);
}The batch:-
@echo off
PING 1.1.1.1 -n 1 -w 5000 >nul
java -cp "c:\ " MainThe important line that makes the whole thing work is :-
@echo offIf this line is missing then the whole things locks up (must be the io streams getting used)
Also this code can not be run from an IDE (well at least not from Intellj) as it also locks up.
It must be run from a command prompt or jar.
Also note that any commands in the batch file must have there output redirected to "nul" otherwise Windows kills the cmd as soon as it trys to output to a dead stream (dead because the Java has exited). for example :-
@echo off
PING 1.1.1.1 -n 1 -w 10000 >nul
cd %1
del /F /Q *.* >nul
move /Y new\*.* >nul
RD /Q /S new >nul
PING 1.1.1.1 -n 1 -w 1000 >nul
java -cp "c:\ " Main
exit

Does java support Flash files?

I wanted to use Flash to display some animation in my application, but I'm not sure if Java will support it. Anyone know where I can find info on this subject?

You can't use Flash in AWT or Swing, if that was what "support" meant in that question. Flash is only a browser plug-in as far as I know.

How to open a BMP file in a JLabel???

Hi all,
My problem is that I want to set a BMP file as icon of a JLabel, but the Class ImageIcon doesn't support BMP files.
Thank you all.

The easiest way to do that is to get a graphics package that can convert a BMP file to a JPG file. Some versions of Microsoft Paint will do that, but you should be able to find another one if you need it.
I hope Brazil wins, but if they don't it will be because the referees give it to Korea.

Display .bmp files

How can I display .bmp files with java?

Yes using JAI - using core methods or just the codec.
You only need the jars. A full install on the desktop or server is not required but the C libs a full install provides MIGHT make things a little faster.

The command is gone because iDVD has been discontinued by Apple. After Apple discontinued iDVD they removed the iDVD burning link from iMovie. I still use iDVD sometimes, only because I have an old copy.

You have mentioned about Handbrake as a converter. What is the RF no. (under Constant Quality) meant? It seems that the smaller the no. is, the better quality will be.

I don't know what RF means. When I have used HandBrake, I've used presets that apply to what I want to do, so I don't know the meaning of each individual setting. However, it appears that many of them are listed in the HandBrake User's Guide that is linked from the Help menu in the program:

Photoshop is not amateur-level software, and although it can edit a video, it cannot burn a DVD. Unfortunately, because I still use iMovie, I haven't tried anything else. You might want to read the reviews of various DVD-burning applications in the Mac App Store.

Creating pie chart diagram in java and converting into BMP file

hi all ,
my req. is to create draw a pie chart diagram and store
the picture in BMP. it is Possible. if so how ?
cheers
senthil

Hi Senthil,
This response is a bit late but I hope it can help in some way. Your requirement (to create draw a pie chart diagram and store the picture in BMP) is possible and actually quite easy if you don't mind using two open source libraries. In his previous response to this thread, Detlev mentioned JFreeChart for as a solution for charting however he also mentioned that it lacks support for BMP. Although this is true, you can use the JFreeChart library (http://www.jfree.org/jfreechart/index.html) in conjunction with an imaging library to meet your requirement. I have used JFreeChart on multiple projects and I highly recommend it. For the imaging library you have many options, however the only one I have used is The Java Imaging Utilities (JIU - http://jiu.sourceforge.net/). Using these two class libraries, you can generate your pie chart and save it to a BMP file with the following block of code:
     try
         JFreeChart chart = this.createChart();
         FileOutputStream streamOut = new FileOutputStream("your/files/path/BMPfile.bmp");
         BufferedImage image = chart.createBufferedImage(600, 300);
         if(image == null)
              reportError("Chart Image is NULL!!!!!!!!");
              return(false);
         RGB24Image rgbImage = ImageCreator.convertImageToRGB24Image(image);
         Codec codec = new BMPCodec();
         codec.setImage(rgbImage);
         codec.setOutputStream(streamOut);
         codec.process();
         codec.close();
         streamOut.flush();
         streamOut.close();
    }catch(IOException ioExcept)
         // throw or handle IOException...
         return(false);
    }catch(OperationFailedException opFailedExcept)
         // throw or handle OperationFailedException...
         return(false);
The first line inside the catch block calls a helper method that should create the actual chart using the JFreeChart library. Once you have your chart instance (all chart types are represented using the JFreeChart class), you can then retrieve a BufferedImage of the chart (JFreeChart.createBufferedImage(int width, int height);). In our situation, the BufferedImage class will act as an "intermediate" class, for both libraries (the charting and imaging) can make sense of BufferedImages. The rest of the code deals with storing the generated chart (the BufferedImage) as a BMP file to disk. The RGB24Image, Codec, BMPCodec, CodecMode, and OperationFailedException classes are all part of the JIU library. Also, note that the storage source is not solely limited to a File on disk; the Codec.setOutputStream(OutputStream os) method will accept any subclass of OutputStream. This implies that not only can you store to the actual App Server disk (where your app is running) but also to sources such as Knowledge Management (KM) resources or even directly to the clients browser (in the case of an iView).
Once again, sorry for the late response and let me know if you have any questions regarding the code above.
Regards,
Michael Portner

How can i build RPMs file for my own Java Application?

How can i build RPMs file for my own Java Application?....I have my own directory that contains all Java Source files and some files that my Application required....I want to build RPMs file like a install File to Linux System, Now my OS is Linux Fedora core 1.....How can i do this?

I think that in order to create a RPM, you'd need to
use some C.Nope - the RPM is all about packaging and the "magic" x.spec file. You can have anything you want in the RPM, but you have to use RPM tools to build the .rpm file. One of the features is that you can also indicate (via "install" scripts) modifications to other files or the filesystem to support the installation of whatever's in the RPM.
