How to shrink wallpaper image?
I want to use a picture I took on my iPhone as the new wallpaper. But when I get to the Move and Scale part, I am having issues. I am able to shrink the image by pinching my fingers. But then I can't tap the Set button? Anyone else have this problem?
You can use animation with scroll , or place image with scroll setup so that when Page scrolls down to a specific position then the large logo hides on page and small logo appears which can be done using scroll movement.

I am looking for a tutorial on how to shrink and image.
So what I what to accomplish is on the main page there is a large main logo than when the page is scrolled down it will move to the upper left (I know how to do this) then is will also shrink down or scale to a smaller image and then I will have it as a sticky header. So lets say the logo is 350x250 and I want to shrink it down to 150x75.
Hope that makes sense...how can I accomplish this?

How to deleting wallpaper images from iPhoto
I have downloaded wallpaper apps onto my iPod touch 4 gen and they appear on my iMack iPhoto Devices section as well I like to know how to delete them since I don't need them any longer.I don't know how to delete them from my iPod either.
If they are in iPhoto simply drag them into iPhoto's Trash Bin at the left and empty it via the iPhoto ➙ Empty Trash menu option.
As for the Touch best to ask in the iPod Touch forum.

How can I retreive my wallpaper image? It is not in my photos. I deleted it from my iphone because i had a copy on my desktop. Then my desktop was stolen and now the only image i have is on the iphone wallpaper.
My problem is the backup is lost too, because the computer that contain the backup was lost with the original photo. It seems to me that the image is stored on the phone in some type of memory. I'm willing to destroy the phone in order to retrieve the image. Any thoughts on where or how the wallpaper is stored on the phone itself?

How to display an image in a window ?
Hi all,
Could someone point me to a document that explains (preferably with code samples) how I go about displaying a JPEG image in a window.
What I'm eventually trying to create is a slideshow, but for now, I just want to add an image to a JFrame and have that display, and even this simple first step is beyond me. There seem to be quite a few different classes to deal with images, but I'm just looking for the simplest one.
With a view to my future requirements, I will want to be able to dynamically shrink an image so that it fits in the window, as well as cropping images so that the full resolution is displayed, but anything that doesn't fit in the window is chopped off.hi,
how to place an image in the cells of a grid and to drag and drop that image. i have the code to locate the postion of each cell on mouse click. now i want to place an image in particular cell and i want to drag and drop that particular image to other cells of grid.

Wallpaper images not showing up in system preferences
hi. my wallpaper images aren't showing up in system preferences/desktop. the folders are there (apple/nature/black and white/etc.) but there are no images in them. the image files are in my library, but i can't figure out how to get them back into system preferences. can anyone help?
thanks so much.that brings up a finder window, and i can get to the folder that way, but the images used to be in the folders in system preferences, and i can't get them back in there. the folders are there, but empty. the files are in the library but i can't move them. help!

White line disappears when I shrink the image
Hi,
I am working in an image that has a drawing with thin white lines over a dark background.
When I shrink the image, the white lines disappear. I would like to know how to thicken the white lines, so that it doesn't disappear when I shrink it...
Thank you,
RobsonHi John,
The image is attached now. I want to make an icon out of it. The image of the icon that I have got so far is attached too. This icon was achieved programatically through C#, so I guess it is messing it, there is even a loss of color.
So I would like to do everything in Photoshop, to leave it ready to be an small bitmap with 24-bit color and all the white lines... -
So I was making image's on my computer for a friend's wallpaper and was curious as to how I achieve that crisp, sharp, high definition quality? Here's a screenshot of my settings for reference.

If you're aiming for a wallpaper image, you should work on an 8-bit image, not 16-bit, and the ppi definition should be the same as your friend's monitor's.

If you want to get exact about displaying print size:
Open a new 500 pixel x 500 pixel file in Photoshop, and set it to 100% (view actual pixels) if it does not come up that way.
Get out a ruler and measure the image on screen in inches.
Divide 500 by the measurement.
This is the resolution of your screen, write it down somewhere. Call it your actual monitor resolution factor.
Why not simply take a screen shot, copy, and create a new document in Photoshop - the suggested document size with be the resolution of your screen. Of course you could just look at your display resolution, but this way you can factor in the task bar layout.
As to 8 vs 16 bit: I recommend always editing in 16 bit, unless your computer can't handle it or you're using PSE. Convert it to 8 bit at the end. Memory is cheap, and RAM is reusable, and heavy processing in 16 bit is far superior. -
I'm trying to create a photo manager but I can't find a way to load multiple images onto my frame. I have a thumbnail class that makes thumbnails for an image (which is a modified version of the class ImageHolder from FilthyRichClient)

A loop will loop through a collection of files and pass them to the constructor of Thumbnails to create thumbnails and then set them as icon for JLabels that will be added to a JPanel, but it throws a java.lang.OutOfMemoryError at this line:
BufferedImage originalImage = ImageIO.read(imageFile);
even when there're only about 8 image files in the collection (total size 2,51MB).
I've seen other people's software that could load hundreds of photos in a matter of seconds! How do I suppose to do that? How to load mutiple images efficiently? Please help!! Thanks a lot!another_beginner wrote:
Thanks everybody! I appreciate your help! I don't understand why but when I use a separate thread to do the job, that problem disappear. You were likely doing your image loading and thumnail creation on the Event Dispatching Thread. Among other things, this is the same thread that updates and paints your panels, frames, buttons, ect.. When a programer does something computationaly expensive on the event dispatching thread then the GUI becomes unresponsive until the computation is done.
Ideally what you want to do is load images and create thumnails on a seperate thread and update your GUI on the event dispatching thread. I supect that while you are finally doing the first item, you might now be violating the second item.
Whatever, the program seems to be pretty slow on start up 'cause it have to reload images everytime. I'm using Picasa and it can display those thumbnails almost instantly. I know that program is made by professionals. But I still want to know how.I took a look at this Picasa you mentioned. It's the photo manager from google right? You're right in that the thumnails display instantly when starting up. This is because Picasa is actually saving the thumnails, instead of creating them everytime the program starts up. It only creates the thumnails once (when you import a picture) and saves the thumnail data to " +*currentUser*+ /AppData/Local/Google/Picasa2/db3/" (at least on my computer --> Vista).
Also, if your looking for speed then for some inexplicable reason java.awt.Toolkit.getDefaultToolkit().createImage(...); is faster (sometimes much faster) than ImageIO.read(...). But there comes a price in dealing with Toolkit images. A toolkit image isn't ready for anything until it has been properly 'loaded' using one of several methods. Also, when you're done and ready for the image to be garbage collected then you need to call Image.flush() or you will eventually find yourself with an out of memory error (BufferedImages don't have this problem). Lastly, Toolkit.createImage(...) can only read image files that the older versions of java supported (jpg, png, gif, bmp) .
And, another question (or maybe I should post it in a different thread?), I can't display all thumbnails using a JPanel because it has a constant height unless I explicitly set it with setPreferredSize. Even when put in a JScrollPane, the height doesn't change so the scrollbar doesn't appear. Anyone know how to auto grow or shrink a JPanel vertically? Or I have to calculate the preferred height by myself?Are you drawing the thumnails directly on the JPanel? If so then you will indeed need to dynamically set the preferred size of the component.
If not, then presumebly your wrapping the thumnails in something like a JLabel or JButton and adding that to the panel. If so, what is the layout manager you're using for the panel? -
Photoshop CS5, is not shrinking PNG images with transparency more then I would like. Including adjusting all options from 'save for web', does anyone have any recommendations or alternatives that I could use ?
Reading between the lines, it sounds as though you need the transparency. What's not so clear is whether you need the 256 levels of transparency, nor what your use for the images is.
- Do you need partial transparency?
- Are these images to be used on the web? How?
- Could something like using a specific background color over the top of a specific background substitute for transparency?
- What kind of images are they? Could they benefit from noise reduction, which will allow the data to compress better?
The PNG format is the only one that's going to give you partial transparency and web browser compatibility.

How to resizing wallpaper on homescreen
How to resizing wallpaper on homescreen on the iPad Mini? As soon as you use the walpaper for homescreen it does not fit. On the screen says "Move and Scale" I did but comes back like you are zooming.
Hi, Jochie.
Thank you for visiting Apple Support Communities.
You may find the information in this article helpful.
iOS 7 uses a parallax effect to create the perception of depth on your Home screen and elsewhere. When this feature is on, you may notice that your:
Wallpaper, icons, and alerts shift slightly as you move your phone.
When setting a wallpaper in Settings > Wallpapers & Brightness, the photo or image will be slightly zoomed and cannot be scaled to fit to the screen.
You can change this behavior by enabling Settings > General >Accessibility > Reduce Motion.
Note: If zoomed, you will need to rescale your wallpaper to fit to the screen.

How can I assign image file name from Main() class
I am trying to create library class which will be accessed and used by different applications (with different image files to be assigned). So, what image file to call should be determined by and in the Main class.
Here is the Main class
import org.me.lib.MyJNIWindowClass;
public class Main {
public Main() {
public static void main(String[] args) {
MyJNIWindowClass mw = new MyJNIWindowClass();
mw.s = "clock.gif";
And here is the library class
package org.me.lib;
public class MyJNIWindowClass {
public String s;
ImageIcon image = new ImageIcon("C:/Documents and Settings/Administrator/Desktop/" + s);
public MyJNIWindowClass() {
JLabel jl = new JLabel(image);
JFrame jf = new JFrame();
jf.add(jl);
jf.setVisible(true);
jf.pack();
I do understand that when I am making reference from main() method to MyJNIWindowClass() s first initialized to null and that is why clock could not be seen but how can I assign image file name from Main() class for library class without creating reference to Main() from MyJNIWindowClass()? As I said, I want this library class being accessed from different applications (means different Main() classes).
Thank you.Your problem is one of timing. Consider this simple example.
public class Example {
public String s;
private String message = "Hello, " + s;
public String toString() {
return message;
public static void main(String[] args) {
Example ex = new Example();
ex.s = "world";
System.out.println(ex.toString());
}When this code is executed, the following happens in order:
1. new Example() is executed, causing an object to constructed. In particular:
2. field s is given value null (since no value is explicitly assigned.
3. field message is given value "Hello, null"
4. Back in method main, field s is now given value "world", but that
doesn't change message.
5. Finally, "Hello, null" is output.
The following fixes the above example:
public class Example {
private String message;
public Example(String name) {
message = "Hello, " + name;
public String toString() {
return message;
public static void main(String[] args) {
Example ex = new Example("world");
System.out.println(ex.toString());
}
