Changing images on a random path

Is it possible to have an image cross the screen slowly on a random path for say 10 seconds, then have another image replace it and go across on another random path? i will have maybe 15 images in toal that I want to do this with!
Thanks

Yes, though a random path may not get you across the screen. You'll need to decide on how you want the random path to be defined.

Automator - Change Image Type - Multiple page PDF- TIFF conversion

I was able to do this on a friend's computer (not sure which version of OS X they were running), but this seems impossible on Snow Leopard.
I need to convert hundreds of multiple page PDFs to TIFFs. I can't get this to work, and the Change Image Type option only lists single page PDF conversion. I could separate PDFs into multiple files, convert to TIFFs, but then I don't know how to recombine a bunch of TIFF pages into a larger file. From google searches, I know this is possible using tiffutil, but I don't really understand how to use that well, and I really need an automatic process.
I'm at my wits end with this, because I did it just last week on someone else's computer and it was easy as pie. Why can't you convert multiple page PDFs in Snow Leopard?
Any ideas?
Thanks!

I just tried this - two problems.
It creates a separate tiff document for each page of the input pdf.
Also, this action is just annoying because it results in randomly named files in some temp folder that i can only locate using the reveal finder item action. I know I can rename files in automator, but I'd really like to have the output file have the same name as the input file.
It confuses me why they would remove this functionality in Snow Leopard.

Dreamweaver template won't change images

I am using Dreamweaver 5 on a Macbook Pro and I have been trying to change the Header image in my site. I would go in and change the image using the CSS panel but the image itself will not update. I've tried deleting the old site definitions and recreating them only to have the same problem.
Nothing will change on my template. It won't aknowledge my changed image "i have saved it under the same image name". i've tried changing the name of the image, re-loading it and still THE OLD IMAGE APPEARS!. What the heck is going on? Can someone please tell me where it is getting this image from when I have clearly changed the image, looked at image to confirm it is in fact the changed image prior to attaching it.
I am completely puzzled and Desperate as my client expects these changes. Thank you. In the mean time I will try to just upload the changed image to the web and hope the template uses the updated image on the server.
Thank you for any help you can offer.

Dreamweaver 5 means Dreamweaver CS5 correct? Can you give us a bit more info on your workflow? How's your site set up? Where does this image reside in comparison to the root of the site folder (make sure the image gets saved to the site folder)? Is the file path to the image correct? Make sure to turn live view off and back on again?

How do you change the color of the path the pen tool makes?

There must be some way to change the color of the path the pen tool makes from that grey color to something that will contrast with the image underneath. I found one thread about this from 2010 or so and the answer led to a dead link. This seems like it would be a very helpful feature that would be easy to implement. Someone please tell me in 2014, after a zillion version of photoshop have come out in the past 30 or so years, how do we do this? Thank in advance.

Why? When you zoom in too close sometimes it become too pixelated to see what's going on and the point on the pen become to close to each other. Why can't you change the path to a color so that it doesn't blend into the image you're trying to trace? Why is the unchangeable color one of the most likely colors to become invisible on most images? So frustrating!

How to change Images with ImageIcon

Hello everyone, this is my first post on the forums.
I am struggling at the moment to find a way to change images in my program. I am making a card game and when the user clicks a button it will replace the card he has with another card. I thought the following code would work but apparently it doesnt:
String cardPathA = "image1.gif";
ImageIcon imageCardA = new ImageIcon(cardPathA);   //cardPathA for example is image1.gif
//during the program the user changes cards so it should now show image2.gif
cardPathA = "image2.gif";
imageCardA.setImage(cardPathA);The error occurs when compiling and it reads: "+setImage(java.awt.Image) in javax.swing.ImageIcon cannot be applied to (java.langlString)+".
I have searched all over the internet and I haven't found anything. I would appreciate some help. Thanks :)

im not really sure i made a quick example to show how I would change the imageIcon in a button, just change the paths for cardPathA and cardPathB for your pictures to get it working.
The only other thing i can think of is maybe to call repaint() for the components you are trying to change the image?
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class ImageChange extends JFrame implements ActionListener{
         final private String cardPathA;
        final private String cardPathB;
     private ImageIcon myImageIcon;
        private JButton changeCard;
        private int counter;
        private JPanel panel;
        private JButton imageButton;
     public ImageChange(){
            changeCard = new JButton("Change Button");
            counter = 0;
            cardPathA = "1.gif";
            cardPathB = "2.gif";
            myImageIcon = new ImageIcon(cardPathA);
            imageButton = new JButton(myImageIcon);
        public void makeGui(){
            changeCard.addActionListener(this);
            panel = new JPanel(new BorderLayout());
            panel.add(changeCard,BorderLayout.NORTH);
            panel.add(imageButton,BorderLayout.CENTER);
            this.add(panel);
            this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
            this.pack();
            this.setVisible(true);
     public void actionPerformed (ActionEvent menuChoice){
            counter++;
            if(counter%2 ==0){
                myImageIcon = new ImageIcon(cardPathA);
                imageButton.setIcon(myImageIcon);
            }else{
                myImageIcon = new ImageIcon(cardPathB);
                imageButton.setIcon(myImageIcon);
        public static void main(String[] args){
            ImageChange test = new ImageChange();

Image display - How do I display an image using an absolute path?

How do I display an image using an absolute path in a compiled WebHelp?
Our developers use RH8 map IDs within our in-house applications to display in a model window created using Telerik Rad Window.
Unfortunately images disappear from these model windows because RoboHelp removes absolute links to [inserted] images and changes them to relative in the compiled WebHelp.
How do we overcome this? Is there a solution in RH8?

I have tried again and changed the path in the topic HTML
from : ..\..\HelpTopics\Icon_Search.png
to : \HowDoI\Help_CMS\WebHelp\HelpTopics\Icon_Search.png
I am obviously unable to see it in RH8 as I have removed the relative link so it is "outside" of the project.
This time, on compilation, it has not stripped out the absolute links. The developer was working with me on this last week and we did have any issue in that they did not hold the absolute link. Most odd!
Checking the published help it appears to be working in the application, which is great.
So my apologies for raising the issue but it really did not work last week.

Change image size on list Field

I have list library which has column of "Person or Group" and selected "Name with (picture)". But i cant change image Size there. its always 62x62. How can i change it?
any idea?
Regards,
Lasantha

How exactly are you wanting to change it? height and width should just be attributes in the element... so.. probably the most simple (but not exactly elegant) way to handle this is to use jQuery.
If you drop the following script into a Content Editor Web Part on your page, it will resize all the profile pics to 100x100. (change the numbers to the size you want):
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function($){
$("img[width='62']").each(function()
$(this).attr("width","100");
$(this).attr("height","100");
</script>
Some Caveats:
1) This script resizes ALL images that have a width of 62. So, if you have some other random image on your page that is 62px wide, it will find it and resize as well.
2) I'm references the jQuery library externally which I do not usually recommend, but at least you can drop this script in and it should just work.
Again, not elegant, and I'm sure someone smarter than me can improve on it, but it should at least get you what you need.
Good luck!

I don't understand this either, I've tried replacing "PaintOff(1)" with "vOn()" but I get the same error. This is baffling to be, as I thought that the hour11 would have access to all the methods inside the PaintOff class?
Anyway, thanks for any help you guys give me!

Hi!
Your problem is that you've used a widening conversion to convert from PaintOff to a JPanel. JPanel has no such method, and so the compiler is complaining that it can't find it.
e.g
public class NoCompile{
     public static void main(String args[]){
          One one = new Two();
          one.methTwo();
public class Two extends One{
     public Two(){}
     public void methTwo(){
        System.out.println("Executed 2");
public class One{
     public One(){}
     public void meth1(){}
} will give you the same sort of error message. To make the compiler happy, use a cast.
Now this will compile and gives the right result.
public class NoCompile{
     public static void main(String args[]){
          One one = new Two();
          ((Two)one).methTwo();
}So in your case, you want to do
((PaintOff)hour11).vOn();
Does that help?

Filter plugin. Problem after change image depth.

Hi All !
I already wrote filter plugin it work fine but only for image depth 8bit, after i change image depth on 16 or 32 bits I getting error msg box from photoshop.
I try change on 'destination.colBits = 8' or 'destination.colBits = pChannel->depth' or ' (pChannel->bounds.bottom - pChannel->bounds.top) * pChannel->depth;' but all the same.
PixelMemoryDesc destination;
destination.data = data; //*pixel
destination.depth = pChannel->depth;
destination.rowBits = (pChannel->bounds.right - pChannel->bounds.left) * pChannel->depth;
destination.colBits = 8;
destination.bitOffset = 0 ;
Please help someone !
Very Thanks in Advance !

Menu Buttons Change Image instead of Highlighting?

Does anyone know how to/or if it's possible to make a DVD menu in Photoshop for Encore where, when the menu button is highlighted it actually changes image instead of making it a solid highlighted colour?
For example...
In a DVD i'm making, I have Cartoon images that are the menu buttons. I would like to make it so that when you select it on your dvd player it makes the eyes open up wider and mouths of the characters open up. I have made the duplicate layers and changed one to have the open eyes and mouth and placed it directly ontop of the other and put both layers in the one group with the (+) to allow Encore to recognize it. But all I get is the top layer of the two turning to a top colour. I know that using prefixes like (=1) makes it highlighted and that is why it's highlighting but I don't know what else to suggest. I've looked at the prefixes on the Encore help on this site and tried to work it out but no luck
I know this is due to my lack of knowledge and really need some help to fix it, or know if it's even possible (I assume tht using such great products as Adobe it will be)
Thanx

Welcome to the forum.
This is easily done by doing dupe Menus for each Button. The Button on the original Menu will be set to Auto-Activate, and be linked to the dupe Menu with the different graphic. I would probably turn OFF Sub-picture Highlights.
The trick is to do a layout, and also name your Menus (especially the dupes), to reflect exactly what they do. I use Illustrator for my layout, but pencil and paper work well too.
Note: if run on a computer, the user will need to Dbl-click the Button, as Auto-Activate only works seamlessly from a DVD set-top player.
There are several other posts on this forum (a few very recent), where I go into much more detail. Also, Jeff Bellune's excellent book, The Focal Easy Guide to Adobe EncoreDVD 2.0, by Focal Press, has excellent, easy to follow steps for doing this. Though written for EncoreDVD 2.0, 100% of the book will apply to CS3 & CS4.
Good luck,

Displaying dynamically changing image: a problem with JLabel.

Hello! I use NetBeans 5.5 and I develop my GUI with Matisse. I'm rather a beginner in developing GUIs with this editor...
I'd like to display a dynamically changing image. The idea is: GUI shows the image, that is modified as some computations run in a different thread. App will be run on a single machine.
I'm trying to display the image as a label's icon. The problem is that my app's frame can be resized - and when it is, the label also resizes. When the label is resized, the image should also be resized - the image should always be of the same size as the label. The problem? I noticed, that it works only when I make my app's bigger. When I try to lower its dimensions, the label's dimensions remain the same. Why the label don't make its size smaller?
My code works as follows: when app's main frame is resize, the panel (the one, that the label is placed in) is also resized. And, since the label is in the panel, it (should) also be resized. So I wrote all the resize-events handlers (therefore I know that the resize event is sent when my app's frame is resized, and when the panel is resized - but the label is resized only when it grows bigger). In this methods I modify the image displayed in the label (I resize the image).
Or, perhaps, there is some other way to show a (dynamically changing) image with Swing... I chose JLabel, because I didn't want to write my own JComponent. JLabel can display image and that is all I need. The problem is: when the label grows bigger, I create a new, bigger image (icon). Why my label don't get smaller (the resize event isn't even sent)?

There is no component that dynamically resizes an image. You need to create your own. Something like this:
JComponent component = new JComponent()
     protected void paintComponent(Graphics g)
          // Scale image to size of component
          g.drawImage(yourImage, 0, 0, getWidth(), getHeight(), null);
};

Changing images on jsp

I created a jsp page with a button and a image (ImageComponent). When the button is pressed a picture is retrieved from a database and saved on the CLIENTs harddrive (ex: "C:\\img.jpg"). After this the image should be changed to the picture just downloaded from the database.
The tried to call the methode:
image.setUrl("C:\\img.jpg");
then the current image dissapears, but the new image isn't displayed.
Did I used the right methode, or should I just call some kind of refresh methode? Can you please help.
THANX

How to change image in jsp in a web application

I had created a web application in which I have given the option to change the image in a jsp, and I am saving that image in a folder.
The image is saved during the run time.But I am not getting that changed image.
If I restart my server the image is retrieved . What is the solution for getting the changed image during the runtime itself?

use javascript
example:
<img id='img' src="Img1.gif" border=0
onMouseover="document.getElementById('img').src='Img2.gif'"
onMouseout="document.getElementById('img').src='Img1.gif'">
