Adding images in applet
Hello,
in my applet, i used 5 no of JButtons using Icon with some ".gif" file.At first ,they run well in appletviewer,But in IE,i got a security exception.After that using policy tool,i created a policy file.Then it works well in IE.But images are not displayed in button.What can i do?.This is very urgent.JButton b1=new JButton("new ImageIcon("2g.gif")");
Kindly tell your consent.
Inba Samuel.
It probably can't find the files for the images. You shouldn't need to resort to changing the policy file just to load an image.
Note that you can't access the local filesystem from an Applet (without signing it or changing the policy file). You don't need to access the local filesystem directly to load an image, though:
URL url = new URL(getDocumentBase(), "image-1.gif");
JButton button1 = new JButton(new ImageIcon(url));This will load the images from the same directory as the HTML page displaying the Applet.
Hope this helps.

I am creating a slot machine and i have
a basic design and drawing. The only thing
i want to do now is add an image of falling coins
coming out of the coin slot at the botom of the slot
machine. i need help in how to put an image in. Like i have
the image saved on my pictures in computer but no clue at
all how to add it into my applet. Heres the applet. Any help at
all would be great. heres the image url of the image i want to add:

I'm developing an applet that contains a Swing GUI. The applet has a DesktopPane which contains several internal frames. These internal frames are meant to be instantiated and added on the fly depeding on user input, so all of thier setup code is contained in thier specific classes, which extend from JInternalFrame.
The Problem is that in the frames I want to use labels and buttons with icons. I am unable to load the images into the frames. I can open an image in the applet class using the getCodeBase method to get to the file name, but I know of no way to get the code base from within the components added to the applet.
Is there any way to load an image from a child componenet, or a way to get the codebase of the parent applet?That did work very wel, but now I'm left with a new problem. The class getrus the URL for the code base, and it looks the same as the original from the applet. However, when I go to create an ImageIcon using this URL, and add it to a component I get no display. No error occurs, and the applet runs fine but the image doesn't display.

Looking for Image Button Applet
I'm looking for a simple image button applet (normal state, mouse-over and mouse-click) which can refer to a HTML or start a Javascript function. Can anyone help?
KippieHi,
This is the source code. I don't quite understand what I should do with the tokens. I hope this is allright. Thanks for your help
Kippie.

import java.applet.Applet;

Program Name: ImageURLButtonBar
Author: Paul Whitelock
Version: 1.1
Copyright: (c) 1997 by Paul Whitelock and Modern Minds, Inc.
Requires: ImageURLButtonBar.class
ButtonBar.class
ButtonBarObserver.class (Interface definition)
ButtonRegion.class
ButtonAnimate.class
Modifications: v1.01 (15 April 97)
* Added "sticky" button behavior (controlled
by applet "stick" parameter)
v1.03 (25 June 97)
* Added applet parameter "useCodeBase". If useCodeBase
is true, then image file locations will be based on the directory
in which the Java class files are located. If useCodeBase is false, then
the locations will be based on the HTML directory. Note that audio
file locations are always based on the Java directory. The default
for useCodeBase is false (use HTML directory for base).
* The "stick" parameter will now accept a button number in
addition to the value of "true" or "false". If a button number
is specified, then that button will be "stuck" down
when the button bar initializes.
* Added the capability of loading multiple URLs for each button
with an optional target for each URL.
v1.1 (25 September 97)
* Added "baseBrighten" and "baseBrightenTint" parameters to control
highlighting for base button bar.
* Added "mouseOverBrighten" and "moBrightenTint" parameters to control
highlighting for base button bar.
* Added "mdBrightenTint" and "mdBrightenAll" parameters to control
highlighting for base button bar. Previous versions of the applet
supported "mouseDownBrighten," but only if button borders were not
drawn for the button-down button bar (the "mdBrightenAll" can be set
to "true" to override the this default behavior).
* An "appletBGColor" parameter has been added to set the
applet background color. The applet background color is
sometimes visible during scrolling or during a page repaint.
NOTE: This source code was composed using Microsoft Visual J++
with tab stops of 4. Text may not be formatted correctly
if another editor is used.

Error while adding Image: ORA-00001: unique constraint
Dear all,
I have an error while adding images to MDM I can´t explain. I want to add 7231 images. About 6983 run fine. The rest throws this error.

I checked all data. There is no such dataset in the database. Can anybody give me a hint how to avoid this error.
One thing I wonder: The PermanentId is allways the same but I can´t do anything here.

For such issues, can you please create a new thread or directly email the author rather than dragging back up a very old thread, it is unlikely that the resolution would be the same as the database/application/etc releases would most probably be very different.
For now I will close this thread as unanswered.

Problem with display of images in applets
Hi all,
When I run this program, the appletviewer window is showing no output (i.e. no image). I'm using the netbeans IDE 5.0.
Blue hills.jpg is present in both the src folder and build folder.
* <applet code="image" width =800 height=600>
* <param name="img" value="Blue hills.jpg">
* <\applet>
import java.awt.*;
import java.applet.*;
public class image extends Applet {
Image img;
public void init() {
img=getImage(getDocumentBase(), getParameter("img"));
public void paint(Graphics g){
g.drawImage(img,0,0,this);
Please help in figuring out the problem....It will be looking for it in the folder with the HTML that invokes the applet.
If you want to pack the image in with the applet then use getResource instead.
And spaces in the name are probably not the best idea. -

Apple have a big flaw adding images to Apple TV coding error.
Hi all, it seems Apple have a big flaw in there new version of itunes 8.2.0.23.
So heres the problem if you have a Apple Tv system. Adding images is great however the softwares flaw is when you have a lot of images. i have over 3000, and tick boxes apear half way in the list, for know reason.
i have add a link to show you guys and girls a screen shot...
can anyone from apple sort this out?
it really bugging me. as it happens of vista, xp, windows 7, and osx.
Cheers

you should report it via the official method - http://www.apple.com/feedback/appletv.html -
hi every body.
I want to display images in an applet when i invoke it from the jsp page . it is not working. the code is as follows.
<html>
<body>
<jsp:plugin type = "applet"
code ="Welcome.class"
width="475" height = "350" >
</jsp:plugin>
</body>
</html>
while the code of "Welcome.java" is as follows.
ImageIcon image = new ImageIcon("aa.gif");
JButton button = new JButton(image);
i have placed the aa.gif file in the same directory where i placed the Welcome.class and the jsp file.
when i run this program the i recieve the message that the applet is not loaded.
can some body help me how to place images in applets.
thanks.You should be able to test that applet on you hard drive first. If it works check the case of the image file.
Web servers look for case. If you are asking for ImageIcon img = new ImageIcon("abc.gif") and what is loaded on your web server is "abc.GIF" it won't find it. Same goes for basic HTML tags like
<Img src=abc.gif>. But it will find it on you hard drive when you run the applet there. -
Adding Images to the List component
Adding Images to the List component while using the FLV
PLayback
All, ( i can send you my source files if it would help)
I'm using the FLV Playback component and loading videos into
it from an external xml file. I also have a list component tied to
the FLV playback that when you click on one of the elements in the
list, it plays that movie.
QUESTION:
My question is how do I add an image to the list component?
Below is the xml file and the actionscript. I've added the image
attribute to the XML file as img="time_square.jpg" and added the
element of the array when calling/creating the list. Did I do this
right?
Any direction would be very much appreciated.Adding Images to the List component while using the FLV

Help with images within applets
I created a card game applet which calls images placed within the same directory. In appletviewer the game runs fine,not in browsers. I downloaded the browser plugin since i use swing classes. If I remove the image the applet loads up without the grafix. Here is the IO error generated. I thought applets can read files within the same directory and sub directories? Would creating a jar file solve this problem? Anyhelp would be appreciated.
java.security.AccessControlException: access denied (java.io.FilePermission main2.gif read)When running in a browser, your applet must be signed in order to be able to access local resources. Check out the "Signed Applets" forum for many discussions about this, as well as methods for signing applets.

Adding images and buttons without a frame appearing
I would like to add images to some of my pages without having them appear in a frame. I would like to place some transparent gifs on the page to use as buttons for hyperlinks. I would also like to have some photos (with transparent backgrounds that appear on the page and are not surrounded by a picture frame. Any Suggestions
iWeb seems to default to stroking newly-added images and shapes. Pages (iWeb's close relation) includes a way to change the default appearance, but I can't find anything similar in iWeb. You can, of course, remove the stroke using the Graphic Inspector (just set Stroke to None). Transparency in gifs and photo images is supported. Just drag into iWeb or use Insert > Choose... Again, remove the stroke if this appears.

Hi
I am trying to add a canvas to an applet. I am successful in doing so. There is a JMenuBar added to the applet. when I click on the file menu The contents are being displayed behind the canvas and as a result I am neither able to see the buttons nor select them. Could some one help me with this.
Note: Once you compile the code you wouldn't be able to see the contents right away. Click on left top,immidiately below the applet menu. This will repaint the contentpane. This is some thing I am working on.
applet class
package aple;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Shape;
import java.awt.geom.AffineTransform;
import java.util.ArrayList;
import javax.swing.JApplet;
public class NewJApplet extends JApplet{
public Graphics2D g2;
AffineTransform atf = new AffineTransform();
sketch sk = new sketch();
@Override
public void init() {
getContentPane().add(sk);
Gui gui = new Gui();
// menubar
this.setJMenuBar(gui.Gui());

this.setBackground(Color.green);
@Override
public void paint(Graphics g){
// g.fillRect(50,50, 50, 50);
}When you were using JPanel, your "setBackground" didn't work because you were overriding its paint(Graphics) method without calling "super.paint(g);". If you don't do this, the panel won't paint its background.
You should also override "protected void paintComponent(Graphics g)" in any JComponent, such as JPanel, instead of just "paint(Graphics)". (And don't forget to call super.paintComponent(g) FIRST in your subclass's overridden method, if you want the background painted):
class MyJPanelSubclass extends JPanel {
protected void paintComponent(Graphics g) {
super.paintComponent(g); // Paints background and any other stuff normally painted.
// Do your custom painting here.

Background layer seizes added images.
I am trying to create a photo collage by scratch (not using "Collage"). First I create a new blank page for the background and save it. It is shown as "locked" with a padlock. Then I open an image file (.jpg) to add to the background layer, and I get a message that I need to unlock the background layer so I click to unlock it. However the added image locks onto the background layer and doesn't make a new layer. If I open another image file it locks on top of the others.
The Layers panel only shows the layer(s) belonging to the currently active file. You need to arrange your image windows so that you can see your composite image as well as the source. With the source image active the Layers panel will show the source - click and drag that layer to the composite.
So in the following, the violet image is the active image and I drag its layer to the white image I've created for my collage. In the composite image with the new layer selected I can position it where I want. Select each of the other images in turn and do the same. Refer to my previous note, you can also do this with Copy & Paste.
When finished, your composite image and its Layers panel will look like this:

i used the following code to save a image it displays from applet.it works fine in appletviewer
BufferedImage expImage = new BufferedImage( (int)this.getWidth(), (int)this.getHeight(), BufferedImage.TYPE_INT_RGB );
Graphics g2d = expImage.getGraphics();
// draftGrid.update(g2d);
this.update(g2d);
g2d.dispose();
OutputStream out = new FileOutputStream( "guru.jpg");
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
encoder.encode(expImage);
out.flush();
out.close();
expImage.flush();
but when i run it in html through my web server the image does' get saved and it the exception i go is
Status code:404 request:R( j
ava/awt/image/BufferedImage.class + null) msg:null
what should i go to save a image from applet throgh browserHello,
This is what I am doing through a servlet call.
If you are just going to let the user download the image you could try the following:
// This works if we are just going to download the image as is
URL url = new URL(request.getParameter("imageURL"));
response.setContentType("image/gif");
response.setHeader("Content-Disposition", "attachment; "+
"filename=\"image.gif\"");
byte buf[] = new byte[1024];
InputStream inputStream = url.openStream();
ServletOutputStream out = response.getOutputStream();
//Read and Write
while(inputStream.read(buf) != -1)
out.write(buf);
out.flush();
out.close();
Or if you are going to manipulate the image a bit before they download it you could try the following:
URL url = new URL(request.getParameter("imageURL"));
response.setContentType("image/gif");
response.setHeader("Content-Disposition", "attachment; "+
"filename=\"image.gif\"");
// use ImageIcon because we are getting the image from a
// URL which might be slow - it has the MediaTracker built right in
javax.swing.ImageIcon ii = new javax.swing.ImageIcon(url);
Image image = ii.getImage(); // now the pixel data is in memory
// get the height and width of the loaded image
int width = image.getWidth(null);
int height = image.getHeight(null);
// create a rectangle as big as the image
Rectangle drawRect = new Rectangle(10, 10, width, height);
BufferedImage bufImage = new BufferedImage(width,
height, BufferedImage.TYPE_INT_RGB);
// get the graphics so you can draw on it
Graphics2D g = bufImage.createGraphics();
// create a nicce white background for the image
g.setColor(Color.white);
g.fillRect(0, 0, width, height);
// reset the color
g.setColor(Color.black);
// add the image
g.drawImage(image, 0, 0, null);
// add any other things you want as well
g.drawString("Just a string", 10, 10);
// create the output stream
ServletOutputStream out = response.getOutputStream();
JPEGImageEncoder jpegImageEncoder = JPEGCodec.createJPEGEncode(out);
// encode it
jpegImageEncoder.encode(bufImage);
out.flush();
out.close();
Hope that this helps.
