Setting JFrame Image Background

Hi everyone, I'm kind of new to Java programming and so far I haven't been able to find a way to set the background of a JFrame to an image. I already know how to change the color but I need to set an image to the background and not just a color. So I was wondering if anybody knew where to find a simple tutorial or instructions on how to do this or if someone could simply explain it.
Thanks for the help :)

Swing related questions should be posted in the Swing forum.
I haven't been able to find a way to set the background of a JFrame to an imageReally? Thats hard to believe as this is one of the most common questions in the forum. What search keywords did you use? Maybe the last two (or three) words from your topic title would be a good start. And searching the Swing forum would be a good idea.
I'm partial to my [Background Panel|http://www.camick.com/java/blog.html?name=background-panel] solution which does what the above postings suggest, plus provide a few other image painting options.

How do you set an image into the background of a JPanel or JFrame?

How do you set an image into the background of a JPanel or JFrame?

Something like this, Ive thrown in an ImageIcon on a
button too for good measure.
import java.awt.*;
import javax.swing.*;
public class JFrameImage extends JFrame {
public JFrameImage() {
Container c    = getContentPane();
JPanel panel = new JPanel(){
             public void paintComponent(Graphics g)     {
ImageIcon img = new
= new ImageIcon("background.jpg");
                  g.drawImage(img.getImage(), 0, 0, null);
                  super.paintComponent(g);
        panel.setOpaque(false);
ImageIcon icon = new ImageIcon("onButton.jpg");
JButton button = new JButton(icon);
panel.add(button);
c.add(panel);
public static void main(String[] args) {
JFrameImage frame = new JFrameImage();
frame.setSize(200,200);
frame.setVisible(true);
Going totally fancy pants
ImageIcon bigImage = new ImageIcon(bgImage.getImage().getScaledInstance(getWidth(), getHeight(),Image.SCALE_REPLICATE));
g.drawImage(bigImage.getImage(), 0, 0, this); Will scale the image to the size of the panel
whereas
for (int y = 0; y < getHeight(); y = y + image.getHeight(null))
for (int x = 0; x< getWidth(); x = x + image.getWidth(null))
g.drawImage(image, x, y, this); Will give a tiled effect
Try tiling with an animated gif and bring your processor to a standstill.

Setting image background transparent

I want to know how can I set the background of an existing images to transparent. I am a web desginer and currently i want's to change background color of one of my site http://twxdroid.com but here the problem arises that some of my used images background won't match up site background, so someone plz tell me how to change existing image background transparent. I heard about using magic wand selection tool or quick selection tool to make transparent but still can't figure out how to use them.

• if the Layer is a Background Layer change it to a regular one by double-clicking it
• make a Selection with whatever Selection Tool is appropriate
• if you selected the background use Select > Inverse to invert the Selection
• Layer > Layer Mask > From Transparency
• if further corrections are needed paint on the Layer Mask – black to hide, white to show the Layer’s content
• save the layered file as psd, psb or tif
• File > Save for Web … to save a copy a format that fits your needs (png-24 for example)

How do I set an image as a background for a course homepage?

I am trying to set a background image for when people visit the homepage (like MOMA and others). Yet, I can't find where/how to do that. Is there any documentation that people of found for the design side of creating an iTunes U course and nav?
thx,
Matthew

Since you are asking in the Course Manager forum, I am puzzled by your question. As a teacher, you can set an image for your course, but there aren't background images for individual courses.
If you are talking about the institutional pages in the iTunes U section of the iTunes Store, your institution's page is managed by your site administrator (using Public Site Manager), so contact him or her to make the change.

I already tried right-click the page, choose View Page Info, then click Permissions. The first item is the site-specific permission for images and you should be able to reset back to the default here. This did not work.
I also tried right-click View Page Info and click Media. Click the first image on the list and observe the Block Images checkbox above the preview at the bottom.

[ANSWERED]Which terminals let you set a random background image?

Many terminals nowadays let you set a background image on the terminal itself.
Which terminals let you set a random background image from a directory or list of images? Also need to be able to have multiple terminals with different background images open, so having a script that moves around images won't work.
I like this because when you have lots of terminals open, you can associate each with their background image. Also if your background image isn't a tiled thing or a stylized gradient (such as a human, etc), it might look bad when duplicated all over the screen.
I could use transparency, but I don't like psuedo transparency, and real transparency comes with all sorts of problems. (For me at least.) I would still prefer having multiple background images though.
Konsole and eterm are the only two I know that can do this, but konsole is KDE, and eterm has no unicode support, is dead (I think), and is ugly.

So now that time has passed and I'm on a clean new install, I decided to try out uxvrt again. The good news in that now I can type in it with scim. I have no clue how or why, but it means the greatest hurdle is gone.
I also even managed to get a good looking English font.
urxvt*font: xft:Monospace:pixelsize=12
Only problem is a readable east asian font. The default font is a mess and everything is squished together. If I explicitly select an east asian font, then there are huge spaces between each letter, even for english. So I find out this is a known bug, and I find a patched aur package for it, but the patch doesn't seem to make a difference.
I know urxvt lets you select a main font and a secondary font and so on. Maybe I did the syntax wrong. I tried both:
urxvt*font: xft:Monospace:pixelsize=16
urxvt*font: xft:WenQuanYi Zen Hei:size=9:antialias=True
and
urxvt*font: xft:Monospace:pixelsize=16,urxvt*font: xft:WenQuanYi Zen Hei:size=9:antialias=True
Neither of them worked. From what my understanding of what the man page says, the size of the cell is supposed to be based on the main font, but in both those cases the secondary font stretches the cells.
Can anybody reccomend fonts for east asian scripts that work well and show me your .Xdefaults ?
FAKE EDIT: I just thought of an idea, and it kinda works:
urxvt*font: xft:Monospace:pixelsize=16,xft:WenQuanYi Zen Hei:size=9:antialias=True
Now I get a readable font, but massive spacing issues between Chinese Characters.
EDIT: About the pixmaps, I got a script to randomly select and image and all is fine, but I can't seem to find a way to disable scaling. I can set the size of the picture by a percent, but it doesn't let me use decimals and it is impossible to get the exact resolution of the picture to display. (Unless I let it tile, but the pictures I am using aren't meant to be tiled.) Is there a way to either disable scaling, or set the urxvt size in pixels so I could make it exactly 640x480. The urxvt man page says that a scale of 1 disables scaling, but it seems to have no effect.
EDIT2: I just noticed I can't use scim now. I have no clue why, but I think compiling it with afterimage support breaks it.
EDIT3: I found out why scim was not working/working. I had to add this to my ~/.scim/global:
/SupportedUnicodeLocales = en_CA.UTF-8
I also got a script that works, kinda:
#!/bin/bash
image="$(ls /usr/local/share/cgs | sort -R | tail -1)"
urxvt -pixmap /usr/local/share/cgs/$image\;86x100
The only problem is that I don't know how to get urxvt -pixmap to keep the aspect ratio of the image. 86x100 is the closest it will let me get to the actual aspect ratio, but it is off slightly. Barely noticable. The man page says that propscale will do this, but it doesn't seem to work.
Either way, for now, I am just going to use 86x100.

Setting the desktop background image via Powershell

UPDATE:
I found the solution that addressed my problem, which I posted in a post below. Keeping the original post for Internet historical reasons as I the hope this helps someone else later on in their search for a solution.
===============
I have Bing'ed and I have Google'd and I haven't found a solid answer to setting the desktop wallpaper programmically. I am trying to do this via PowerShell, but I would be happy for any other language flavor or application to work.
Below is the code I have tried to set the desktop background image. This has been scrounged from a few sources across the web. This solution works 25% of the time and I haven't figured out what the cause for success or failure of the execution. Or maybe
it's neither, but waiting for Explorer to refresh. The only way to see the change 100% is to log out and log back in.
I am running Windows 8.1 btw.
Thank you for looking.

Great news! I found the solution and all props and credit goes to
jsd1982 of the XKCD comic
forum from a post he made in 2007 and some deep search kung-fu Googling on my part. Here is the
direct link to the post.
This solution has worked for me 100% of the time on Windows 8. The only gotcha I found (minor detail) was when setting this process to run as a scheduled task, I had to run it as elevated privileges for the code to compile in memory. Running this function
from PowerShell at the command prompt was fine.
NOTE: The code below is a slight trimmed down version posted by jsd1982 to just set the desktop wallpaper. I removed the image fetching from the Internet and the color inversion.

Set Table Row Background image

Hi all,
I'd like to set a Table row background image, but I only find a way to set a background image for each column, is there any way to set an image as background for a whole row?

Hi Pakojones,
Based on my test, it is not support to make the image tile in a row. The BackgroundRepeat values of tablix is Repeat, RepeatX, RepeatY, or Clip. In SSRS, just chart BackgroundRepeat can be set to Fit.
Reference: http://technet.microsoft.com/en-us/library/dd239334.aspx
In SSRS, we can put tablix in a rectangle, then add background image for the rectangle. We can tile the image over the whole tablix. If we want to make the image tile in a row, we can put the single row in a rectangle to work around it. In this situation,
we have to seamless paste the tablix in the end.
Alternatively, since the issue is by design, I recommend you that submit this suggestion at
https://connect.microsoft.com/SQLServer/ . If the suggestion mentioned by customers for many times, the product team may consider to add the feature in the next SQL Server version. Your feedback is valuable
for us to improve our products and increase the level of service provided.

How do you set a transparent background when adding an image?

I've added a block arrow image to a slide in Captivate 4. I enabled Transparent background and selected white as the color within the Image properties. This used to work when I added the same image in Captivate 3. However, in Captivate 4, when I publish, the image displays with a white background. Though it is transparent in priview mode and on the slide iteself when i have the project open. Any ideas on what else I could do to make the image background transparent?

Hi there
Transparent background should still work in Captivate 4 just as it did in Captivate 3.
There are a couple of reasons it may not do what you are expecting.
The background isn't truly the color it appears to be. For example, it may APPEAR to be solid white (or another color) but in reality it's hundreds of varying shades of the color. This happens a lot with JPEG images.
If the image is PNG format, I've seen Captivate become confused. Especially if the PNG already has a transparent background. So you may need to edit the image and save in a different format.
Cheers... Rick
