Creating an image of a GUI

Hi!
Just had a quick question. Does anyone know how to create an image as a gif or jpeg of a GUI in a program. I want to capture the image to use in a Powerpoint presentation, but have now idea if it is possible to create an image of the graphic user interface.
Thanks in advance,

if you think of their name then post it on here. i'll
keep a watch on this topic. incidentally, i'm sorry
all you can think about is cream cheese as i hate the
stuff.Creamcheese is a piece of Nirvana, especially when sitting under a fat slab of lox and on top of a nice onion bagel.

most programmers i know, personally, tend to be
creatures of least resistance so i have the habit of
finding the quickest solution possible. you seem to
be a creature of most fun. i really like your harness
screen capture idea and i think i might write one just
for fun.A creature of fun, yes, but also of practicality. Many years ago I did this type of harness for DOS programming under Turbo Pascal. It was a test suite. The tester would run through the program, and when they saw an error on the page they'd hit a hot key. The harness would come to life, snap the image on the screen, ask for information about the error (change/error, category of error, description, etc), and log it out to file. The file was then sent to the developer who could then use the complementary app to read the file and scroll through the issues/errors at leisure, or just print the entire report. Back the file would go again for the tester to sign off on.
now that i think about it.. indeed, it wouldn't be bad to recreate this for apps today. JUnit only does so much on the "I know this to be right" arena, and doesn't allow for human understanding of "what's right".

How to load an image without a gui? big problems...

Hey guys, I usually try my best to not ask for help and figure stuff out myself. But this last week i've been having big problems with this work project.
My goal is to load images from disk, and append them to each other to create one big image.
The images are 0-9.jpg each file containing a number in it. then i create one big file with 4 numbers in it. called final.jpg.
so far i can do all this, but whenever the program is finished, the application just keeps running. the program has literally gone through all the steps... i have a system.out.println printed on the last line after the main, after the class instantiation... and still it stays running.
how do you guys load images without a gui? This program will probably be running under unix, so i can't create a (for component example)
Panel() and media track the file load... so i'm pretty much stumped
any help you guys can provide would be really incredibly helpfull at this point. I have searched these threads for a few hours without luck. I found only 1 real post related to my problem, but eventually they said use MediaTracker = new Mediatracker( new Panel() ); which i can't use. :(
Thanks a lot guys.
:D

yeah tried doing that, didn't work either.
UPDATE
I FINALLY found a way...
and here it is for others to find!
public BufferedImage getImage(String filename) throws Exception {
FileInputStream input = new FileInputStream( filename );
JPEGImageDecoder decoder = JPEGCodec.createJPEGDecoder( input );
BufferedImage image = decoder.decodeAsBufferedImage();
return image;
it returns an image buffer, but it's better than nothing! :)
atleast this functions under unix.

System Image Utility fails to create boot image

I am not able to successfully build a boot image with the System Image Utility. The build starts and runs for about 1 minute and then I get 100's of ditto messages saying "No space left on device". There's plenty of space left on the device. Eventually I get a GUI message stating the there was an error creating the image. The image is of course unusable. This only happens on a Boot image. I have no problem making an install image from the same source. Is it just me??
Xserve G5 Dual Mac OS X (10.4.5)

I had simililar problems with much headscratching as the result.
I found that whenever I tried to create a boot image with System Image Utility (SIU) using an image file of my existing system as the source SIU would fail with the annoying "No space left on device" message everytime. I did a little investigating and found that SIU always created a 400 MB disk image file to copy to. So the error message was correct as my source was way over 4 GB.
I checked the manual and found the embarrasingly simple solution. It's not mentioned directly, rather it is stated that when you want to create an boot image from an existing system you should boot the machine containing the desired system on disk from an alternate source and the run SIU on that machine. The "trick" is that you're running SIU with the existing system mounted as a disk.
So I went back to my Xserve, mounted the image so it appeared on the desktop. Ran SIU and chose the mounted volume as the source instead of the image file, and hey presto!

How do i create an Image in my own class

Hi!
I have a class
public class gBuffer {
which is used for double and tripple and n-th
buffer of graphics.
I need to create an image in the constructor, but
the only way i could do it is something like:
Applet a = new Applet();
Image i=a.createImage(100,100);
I just could not find any other class where createImage()
is not abstract.
How do i do it right?

You need a real live Component object that will enable
you to do something like this:
Component c = get_a_Component_from_somewhere();
Image writable = c.createImage(100,100);
Graphics g = writable.getGraphics();
g.drawxyz(...);
g.dispose();If you're programming from within an application or servlet,
with no real GUI components available,
then you might have a problem. You might create a
Frame object without ever making it visible.

Displaying Images in my GUI

I have created a GUI that lets me display images that a user selects from a file. However is it possible to display an image that has not yet been written to a file?
I have a class that takes an image object, perfoms operations on it then maps this to a new image object. Would it be possible to display this image before it has actually been written to file? If anyone out there has ideas i'll be very grateful.
Here is an example of how I map one image to another:
     // Creates an image object.
     MyImage imageRight = new MyImage();
     // Now read in the image file
// Create new object for reading image
     MyImage imageCenter = new MyImage(imageRight.getWidth(), imageRight.getHeight());
/* Copy the pixel information from image that was read in to the
     new image */
     for (int y = 0; y < imageRight.getWidth(); y++) {
               for (int x = 0; x < imageRight.getHeight(); x++) {
          /* Get the values from imageOne */
          int red = imageRight.getRed(x,y);
          int green = imageRight.getGreen(x,y);
          int blue = imageRight.getBlue(x,y);
          /* Put these values into imageTwo */
          imageCenter.setRGB(x, y, red, green, blue);
At this point before I write the file, you can see that imageCenter holds all the attributes of an image. Now can I display this image object in my GUI?
I hope someone can help me as this is really important.
Thanks again.

Look into the graphics's drawimage method.

Create a Image viewer

I would like to create an image viewer applet, so that I am able to display lots of images as (thumbnails) and also to be able to select and display one image at a time, as well as zooming in and out. How do I get started? What good books can help me? Please help?
thanks

Look to the left under documentation. There us a nice Tutorial
section. First start with making simple applets. Once you
are done, move into making GUIs so you get a good handle on
components and containers. Finally, as was suggested, read
anything you can find in there about JAI. Your best friend,
when you are done the tutorials, should be the API as it
provides all the classes and methods that you should need.

Newbie Help: Java Object to create an image

Hi there.
I'm trying to create a Java class that I can call from Coldfusion that will build a GIF file based on parameters.
The idea is, the Java object opens a "background" gif file and then writes some text onto it and saves the whole thing out as a GIF.
Bearing in mind this class will be used directly by Coldfusion, and so isn't an applet or an application...can anyone tell me what is wrong with this code as I get a null pointer exception on the getGraphics() line:
// Methods available to Coldfusion
public String CreateOverlay( String imageFile, String outPath, String overlayText, int x, int y, String fontFace, int PointSize)
try{
Toolkit tk = Toolkit.getDefaultToolkit();
Image im = tk.getImage(imageFile);
Gif89Encoder enc = new Gif89Encoder();
OutputStream out = new BufferedOutputStream(
new FileOutputStream(outPath)
Image newimg = createImage(100,50);
***** Graphics g = newimg.getGraphics();
g.drawImage(im, 0, 0, 100, 50, this);
g.drawLine(0,0,50,50);
enc.addFrame( newimg );
enc.encode(out);
out.close();
catch (Exception e) {
System.out.println("Error...");
e.printStackTrace();
return "Dont care at the moment";
Any help to this troubled newbie would be appreciated.

Hi Kurt,
You must call "setVisible(true)" on your Frame before
creating the image.But, the thing is, this object doesnt have (or need) a GUI. Its just an object that sits on the server and its methods are called to generate an image on disk. Basically what happens is Coldfusion receives information from a user and it loads the java object, calls a method which then generates a new GIF file that is made up of a simple button background and some text (entered by the user)....it then returns the name of this file to Coldfusion and Coldfusion stores it in a database for later retrieval.
In simple terms:
COLDFUSION===========
1. Creates an instance of the JAVA Object
2. Call the generateGif method passing an image filename and some text eg:
newFile=c.GenerateGif( "simplebutton.gif", "Some text for button");
JAVA OBJECT========= (GenerateGif method)
1. Load the GIF simplebutton.gif
2. Create a new blank image
3. Draw the loaded GIF onto the blank one
4. Write the Text ("some text for button") onto the image
5. Take the image and encode it to GIF format
6. Write this GIF to disk
7. Return the filename of the new GIF image just created
8. Finish
As you can see, I dont want or need a GUI.....
Is this possible ?
Thanks in Advance,

How do I Create interactive images to be used in another website?

Our office is contracted with a simple website company, so from the begining the framework is there. I want to add an interactive map that has each county hyperlinked to information about that area. I was told that Dreamweaver is the program I would need in order to create it.
So, I have the program now but every tutorial I read is about making your own website in dreamweaver and I can't find anything about how to create the image to upload into a different website.
Anyone know how to do this????
Thank you!

This helps, thanks. I have the content on the web page (where the hyperlinks will attach to), I have the image of the map, and I am making the shapes for the hotspots, just not how to get it all to link up.
Also, when I saved a trial (just to make sure it would all work) it doesn't successfully upload as an image onto the website, just a little box with a red X. Any more thoughts anyone?

Class casting, creating an image and decompiling...

Hi, I've got a couple of questions:
1)
How can I fully decompile classes, so with the implementation of the methods? Is it always possible to fully decompile a class file? When is it and when not?
2)
I aks this questions before, but I still haven't got it working, so sorry, but I ask it again :) :
I want to create my own class, for example cMyClass which extends the java.awt.Image class, which has abstract methods. How do these methods(for example getGraphics etc) have to be implemented?
3)
I can't cast a Image to cMyClass... why not?
Someone told me he did the following:
Canvas c = new Canvas()
cMyClass oImage = (cMyClass) c.createImage (100, 100);
and that this worked... I tried to do this too, and it seemed to work, but it actually didn't!!
I found out that c.createImage returns a null reference!!! That's why Java was able to cast it to my own cMyClass (not a problem to cast a null to something else), but when I created a Image (by doing a lot of unnessacary difficult stuff), and then tried to cast this Image to cMyClass it throw a ClassCastException or something like that...
How can I cast the java.awt.Image class to my class anyway?
3)
Why can't you create a image like i've done above or even like below:
Canvas c = new Canvas()
Image oImage = c.createImage (100, 100);
Why does this return a null reference?
Isn't there a better way to create an image?
4)
The getWidth and getHeight need a I thought observer...? Why is this? I just want the width and height and don't have an observer or something like that. Is there a way around this?
I tried getWidth(null) but this returns -1
Please help! :)

Hi, I've got a couple of questions:
1)
How can I fully decompile classes, so with the
implementation of the methods? Is it always possible
to fully decompile a class file? When is it and when
not?You can always get a dump of the bytecode with 'javap -c'. If you don't want to figure things out yourself, try searching google for a class file decompiler, possibly a de-obfuscator.
De-compilation is completely possible if the original author wanted that, by including debugging information. Depending on the degree of such information and the amount of code obfuscation, the decompiled code may lack variable names, line numbers, field and method names, class names, and even code structure. Names and line numbers are usually not re-creatable automatically, since the information is simply lost, but you can replace them with your own strings when analyzing an unknown class file (using the correct tools). Re-creating the original code structure may work in some cases, but to me the general case looks rather close to the halt problem (i.e. not solvable).
Use a de-obfuscator, hope you've got good luck, and analyze the bytecode manually if that doesn't work.
2)
I aks this questions before, but I still haven't got
it working, so sorry, but I ask it again :) :
I want to create my own class, for example cMyClass
which extends the java.awt.Image class, which has
abstract methods. How do these methods(for example
getGraphics etc) have to be implemented?I don't really understand the problem. 'abstract' means on the language level that your subclass must provide an implementation, i.e. a method body. What that method is expected to do is explained in the javadocs for Image. But in fact you're free to do anything. You could play a sound in the getWidth() method (replace with any method name if you want). Just consider the fact that a lot of code calls getWidth in the hope of getting the width of the image, not playing a sound. So much about the language level.
On a higher level, a subclass of Image should implement a certain way to describe an image. AFAIK this means that your code must know the size of the image and know how to produce the pixels of the image. I can't tell you in general how you must do this, because it depends on your special case. This boils down to the question, why do you want to write a subclass of 'Image'? What new way of describing and image have you come up with?
3)
I can't cast a Image to cMyClass... why not?Simple, and that's certainly not an ALT. Because that specific Image is not a cMyClass. It's probably a BufferedImage or similar that was produced by AWT.
Please read the specs carefully what casting is about.
Someone told me he did the following:
Canvas c = new Canvas()
cMyClass oImage = (cMyClass) c.createImage (100,
100);
and that this worked... I tried to do this too, and it
seemed to work, but it actually didn't!!
I found out that c.createImage returns a null
reference!!! That's why Java was able to cast it to my
own cMyClass (not a problem to cast a null to
something else), but when I created a Image (by doing
a lot of unnessacary difficult stuff), and then tried
to cast this Image to cMyClass it throw a
ClassCastException or something like that...
How can I cast the java.awt.Image class to my class
anyway?You can't, and if you understood casting then you'd understand that it wouldn't make sense.
3, 4(don't know)
Maybe stupid question, but for example the BufferedImage, is this
completly written in Java?
How is the link made between the OS+hardware and the Java code? I
mean, displaying images etc. is very platform dependend not?Look for JNI (Java Native Interface). It's a way to link native (e.g. C) code with Java code.

Unable to create Disc Image from DVD

I get the following error when trying to make a copy of a family wedding DVD. I'm using Disc Utility and creating the image as a DVD/CD master (.cdr) file. It gets to about 3/4 of the way and then gives the following error.

I do not know what that error means. However, if you open up the Disk Utility & go into it's Help Menu & in the search field type duplicating a CD or DVD. There you will find detailed instructions on how to create a disc image from a DVD.
Good possibility your answer may be found there and/or there may have been something you missed in creating a disc image.
Good luck.

How can I create an image gallery with "next" buttons?

So I am almost done with my portfolio site (YES!)..now I just need the actual content (the images). My site is written in AS3.
I've watched many tutorials on how to create an image gallery (auto scrolling ones, scrolling ones that require mouse hover, etc etc), but those aren't what I am looking for.
I want a gallery that looks exactly like this one here:
http://jalbum.net/res/help/integrating-tutorial.html
I have a lot of work to display in my porfolio so there must be arrows at the end of the thumbnails so I can add more stuff. So I am just stumped on how to make the image gallery work with the ability to scroll for more photos with the click of the arrows.
Any ideas? Thank you.

Watching tutorials and learning from them are two different things. If you have learned from them you should be able to use what you have learned to devise a gallery such as the one you link to. If you have learned from them and cannot use what you learned, then you probably need to find/learn more.
If you study the design you linked you should be able to reason out what elements you need to devise... it is not overly complicated.
For the large picture you could have a Loader into which you load whatever image is selected from the thumnails. To get a brief transition you could just set the alpha of the Loader to 0 when an image change is occuring and gradually fade it in after the image has loaded.
The greatest challenge you are likely to face is in getting the thumbnails to advance back and forth depending on which is selected. All of the thumbs would be placed in a container (movieclip or sprite) and that would be masked so that only a portion of them is visible.
All thumbs that are not selected have their alpha property set to some value less than 1. Selecting one calls for the file it associates with to be loaded into the Loader. If the choice happens to lie off screen, then you need to move the movieclip that contains all of the thumbs some set value in the right (+x) or left (-x) direction.
If you want the thumbnails to wrap infinitely then when one leave the thumbnails area for movement in a direction, you need to take that thumb and relocate it to the other end of the thumbs in the container.

Problem in creating 1 image using differnt images

Dear Fellows I want to create an image by using different images in byte array format. Images may be transparent or normal images. I want final result in byte array. I am using the following technique which is working fine but the problem with this technique is that it takes too much time to create an image. This is because I am using MediaTraker. If I delete the code of MediaTracker then program have undeterministic behavior i.e, sometimes it create the final image properly and sometimes nothing is displayed in final image.
I need some help from you. If anyone of you know the technique to draw image using different images without using mediaTracker kindly let me know.
Early replies will be appreciated

Is there a way to create an image of a CC installer that way I can install without internet?

I work for a college that has a department of over 100 mac computers currently runing 10.6 and above. I am the IT here and am in charge of installing all programs the students use, so ease of installation helps. I know I can install using an internet connection and it seems pretty simple, my issue is that if for some reason I dont have internet connection in the department I wouldnt be able to install the programs. What I want to know is if I can somehow create an image for the CC softwares, such as Photoshop CC, that way I can create more images of that installer, put them onto external hardrives and install that way without using internet. hope thats enough information, thanks for the help.

Creating an image from a Mac and restoring it in another Mac

Hi,
I've spent a couple of hours trying to make a copy of one of my macminis, trying to copy it in another macmini to have the SAME machine "duplicated".
I've read some tutorials online, but something is going wrong....
First of all, I went to my "master" macmini, DiskUtility, create new image from folder, select my macintosh HD and I created the image of the whole HD.
Almost a hour after, the image was created.
Then I moved the .dmg to a USB drive, and I connected the USB pen to the machine that I want to be a "clone" of the master. There, I opened Disk Utility, Restore, I selected the Source image from my USB, but I can't selected (=drag) the Macintosh HD into the "destination" field...
What I'm doing wrong?
Thanks, any help is appreciated :))

Hi sr.richie;
If you are booted from Macintosh HD then the system will not allow this cloning operation to take place. You must boot from another disk in order to do that.
