Animated GIF error

I've joined Creative cloud and was able to create the swf file in Flash Pro CC. Would like to export it as an animated Gif but when I do that it won't play and seems to be a single image. When the swf is created I get this error.
Symbol 'catjum[', Layer 'Layer 2', Frame 69, Line 1, Column 1
1180: Call to a possibly undefined method getURL.
Please help!

If you are using Flash CC and you have getURL somewhere in your code, that getURL will be the problem since it is AS2 code and Flash CC does not support AS2 code.

Saving animated gif error - canvas size too big?

Hi,
i have been asked to create an animated gif which has a snow effect in the background. The animation runs pretty well using the pattern style to move the animated snow down. The problem is when I try to export the animation the save for web dialogue window freezes and I can't quit photoshop. I have tried to make the canvas (image size) smaller and it works.
Is there a memory problem with creating animations in Photoshop if the document size is too big, im running a 3000x1000px at 72dpi
TThe animation would be used on a web app, which a script could probably do a better job, but I need to try this first.
thanks

Something is very wrong here. The point behind using GIFs is that they are small and OK to put on a Web site.
First thing: forget all about PPI - this has absolutely no relevance to Web/screen images; it is only used for printing. You need to think about the pixel size.
So, how big in pixels are your starting images?
How big do you want the resulting GIF to be? Again, you have to decide in pixels, as the viewing size will depend upon screen resolution of the person looking at it. You can use a notional PPI of 70-100 to guess how big it will be in inches, but that's all it is - a guess.
Is this getting you going in the right direction?
I cannot resist commenting that I hate almost all animated GIFs as they reduce Web site usability so much.

CS1, CS2, CS3 Animated Gif Creation Error.

Example: http://img365.imageshack.us/img365/5665/walksz2.gif
Whenever I made an animated gif with a transparent background, the above happens. It doesn't hide the previous frame when drawing the next one. However, when I give it a non-transparent background, it is still fine - http://img59.imageshack.us/img59/8080/walklk4.gif
How can I fix this? This happens in Photoshop CS1, CS2, and CS3.
Thanks,
Dave.

Read up on "frame disposal method."
Here's a link to the online PS CS3 live documentation about the subject. This info applies to all the versions you mentioned:

Resized animated gif ImageIcon not working properly with JButton etc.

The problem is that when I resize an ImageIcon representing an animated gif and place it on a Jbutton, JToggelButton or JLabel, in some cases the image does not show or does not animate. More precicely, depending on the specific image file, the image shows always, most of the time or sometimes. Images which are susceptible to not showing often do not animate when showing. Moving over or clicking with the mouse on the AbstractButton instance while the frame is supposed to updated causes the image to disappear (even when viewing the non-animating image that sometimes appears). No errors are thrown.
Here some example code: (compiled with Java 6.0 compliance)
import java.awt.*;
import java.awt.event.*;

          for (int i = 0; i < IMAGES; i++)
               p.add(this.buttons[i] = new JButton());

          f.setVisible(true);
          this.refresh();
     public void refresh()
          this.doScale = !this.doScale;
          for (int i = 0; i < IMAGES; i++)
               ImageIcon image = new ImageIcon(i + ".gif");
               if (this.doScale)
                    image = new ImageIcon(image.getImage().getScaledInstance(180, 180, Image.SCALE_AREA_AVERAGING));
               image.setImageObserver(this.buttons);
               this.buttons[i].setIcon(image);

               this.buttons[i].setPressedIcon(image);

When you press the "Toggle scaling"button it switches between unresized (properly working) and resized instances of three of my gif images. Notice that the left image almost never appears, the middle image always, and the right image most of the time. The right image seems to (almost) never animate. When you click on the left image (when visble) it disappears only when the backend is updating the animation (between those two frames with a long delay)
Why are the original ImageIcon and the resized ImageIcon behaving differently? Are they differently organized internally?
Is there any chance my way of resizing might be wrong?

It does work, however I refuse to use SCALE_REPLICATE for my application because resizing images is butt ugly, whether scaling up or down. Could there be a clue in the rescaling implementations, which I can override?
Maybe is there a way that I can check if an image is a multi-frame animation and set the scaling algorithm accordingly?

Create animated GIF using imageio

How do you create an animated GIF using the J2SE's javax.imageio classes?
I have been browsing these 3 threads (one of which I participated in) to try and develop an SSCCE of creating an animated GIF.

(pity I did not prompt the OP on that last one, to supply an SSCCE.)
Unfortunately, my efforts so far have been dismal. Either, without the IIOMetadata object, the GIF has frames with no delay, and it cycles just once, or with the IIOMetadata object I get an error.

According to imagio's [gif metadata specification|http://java.sun.com/javase/6/docs/api/javax/imageio/metadata/doc-files/gif_metadata.html], the metadata you are specifying is image-specific metadata. The stream metadata is global metadata applicable to all the images.
So change this,
IIOMetadataNode root =
    new IIOMetadataNode("javax_imageio_gif_stream_1.0");to this,
IIOMetadataNode root =
    new IIOMetadataNode("javax_imageio_gif_image_1.0");and this,
IIOMetadata metadata = iw.getDefaultStreamMetadata(iwp);

//metadata.mergeTree(metadata.getNativeMetadataFormatName(), root);
metadata.setFromTree(metadata.getNativeMetadataFormatName(), root);
//Node root = metadata.getAsTree("javax_imageio_gif_image_1.0");to this,
IIOMetadata metadata = iw.getDefaultImageMetadata(
        new ImageTypeSpecifier(src),null);
System.out.println("IIOMetadata: " + metadata);
metadata.mergeTree(metadata.getNativeMetadataFormatName(), root);Here is your program again, but with the above changes.

Animated GIF frame loss

I have an applet that has a JPanel with a JLabel in it. That JLabel was created with an ImageIcon constructor with an animated gif image. The gif has eleven frames (each with replace set) and is set to loop. When I bring up the applet the image animates through the first 7 frames then stops. I can File/Open the gif in Netscape and it looks fine - animates all images and loops. Looking at it with:
setDebugGraphicsOptions(DebugGraphics.BUFFERED_OPTION); or FLASH_OPTION
it looks good until that 7th frame then I start to see flash of grey the size of the JLabel.
I understand that the ImageObserver defaults to the JLabel. But I have tried directly setting it with no joy. I have also tried calling .flush() on the image with no joy. So I tried a different animated gif and it stopped on the 3rd frame (but also appears fine in a browser).
I am on day 2 of trying to figure this out (pulling my hair out).
I cut this down quite a bit, so there may be syntax errors.
public class RRR extends JApplet implements RRRConsts
public void init()
loadImages();
myJPanel = new MyJPanel();
contentPane.add(myJPael);

catch (Exception e)
{ logger.log(Level.SEVERE, "Unable to load images", e); }

MediaTracker tracker = new MediaTracker(this);
tracker.addImage(image, 0);
tracker.waitForID(0);
return image;

I just had the same problem. It seems that when using an animated gif as ImageIcon it will not be loaded compeltly if it is too large. The maximum seems to be somewhere between 60 - 70 KB.
I managed to use a higher compression on my gifs to make them smaller, but I haven't found any general solution yet.

Why does animated .gif not work with windows?

I have created an animated .gif to place in a powerpoint presentation, but when I sent it to my client who used a windows computer, it does not work. When I try to open the .gif in my windows 98 virtual machine, it says it has errors.
I created it in photoshop CC using the timeline and saving it with "save for web".

AAAAAAAGGGGGGHHH! Stupid Powerpoint corrupted the files when it "packaged" them
Thank you for pointing me in the right direction.
It is very difficult to figure out what my client is doing on his end.
It won't let me mark you both as correct.

Animated gif is not moving in the FireFox 3.6.3 ?

why animated gif is not moving in FireFox 3.6.3 ?
== This happened ==
Every time Firefox opened

Same problem in save mode. An animated gif will not start. No offending plugins or themes are installed.
But if I right-click on the animation and then on "Grafik-Info anzeigen" (maybe "show grafic info") then as soon as the info window starts the animation, it is also started in the browser!
And this error does not happen on all machines. My Win7 64bit does it right. My XP 32bit (freshly updated) freezes the animation. Weird world.

Animated gif in photoshop

Hi
I'm running Photoshop 7 on a MacBook Pro. I previously used photoshop on a PC.
I created an animation using layers, and saved it as an optimised gif. However, when I tired to upload it to MySpace it would load: error message said it was an unsupported format.
I didn't have this problem before on the PC - any ideas what is different or how I can fix it?
THanks
Seamus

Hi, my apologies if that sounded condescending. Indeed I'm getting the same error as you do when trying to upload animated gif files created in either PS CS2 or IR CS2. I don't know what this site's problem is, because my gifs run in any browser. I have found that myspace accepts a gif file only when I open it in Safari and drag it from the browser window to the desktop first. Go figure.
I know it's annoying to have to open every gif file in Safari and drag it from the browser to the desktop, but at least it works this way.
It might just be some optimization setting in IR, although I wouldn't know what.
Good luck

Animated GIF. problems in Captivate

I have been trying to bring in an Animated GIF. into my
Captivate presentation.
When I import the animation using Insert> Animation it
converts the animated gif to a swf file.
In the preview screen it shows my animated gif with multiple
colors flashing over and over. It is doing this to all of the
animated gifs that I am bringing in. My fps is set to 10 within
Captivate.
Is there frame restrictions or file size restrictions that is
causing this error when bringing in an animated gif. Any
suggestions?

Hi mikeygilbert23_nap and welcome to our community
Unfortunately, there are a few different methods used to
create animated .GIFs. One would think all of them would be created
simply using different images. Largely this is true. But some
animation programs allow you to choose different methods for the
way the screen is painted between frames. Sounds like you may be
seeing this behavior.
Not sure what to advise as to how to work past it though.
Sorry. Hopefully one of the others has a clue.
Cheers... Rick

Can Premiere Elements be used on an animated gif file?

I am considering purchasing Premiere Elements but I need to know if one can use it to add effects to an animated gif file.
For example, in Photoshop Elements one can add certain effects to a gif image, such as giving it certain textures or filters.
Can one do the same kind of thing in Premiere Elements and if so can it be done to an animated gif file?
Maybe a better way to ask this question is: can you import an animated gif file into Premiere Elements and then manipulate it? Run filters, etc.
Thanks for your help.

If you load your GIF into Premiere Elements 10, edit it, then share to an AVI file, you can then import the AVI file into GIF Movie Gear by Gamani, which will then create an animated GIF. I learned about this utility from a Microsoft tutorial on creating icons for Windows XP.
http://www.gamani.com/product_icon.htm
If you use Firefox and get redirected, try using Internet Explorer instead.
After the trial period is over, it's $29.95US for 4 licences.
When you share to an AVI file, you will want to select the Microsoft AVI item from the list, then click the advanced button to open up the dialog where you will need to select a codec and enter the frame size and frame rate. The codec will have to be one that GIF Movie Gear likes, so there may be some trial and error needed to get a good codec. I shared to an AVI after picking Xvid for the codec, which GIF Movie Gear imported.

Import animated GIF from Photoshop?

I have a question... I am unable to create custom animated gif's in Photoshop 5/6 and import them into Captivate 7. It just says "The GIF file contains errors". I've tried exporting on multiple settings and still no luck, same with exporting from Fireworks.
I am however able to import an exported gif from Flash, yet the quality is horrible and the transparency is buggy. Is anyone else having this issue, or is there some setting that I am missing? Basically I need to animate some images within a Captivate project, without the need of using a .SWF (for HTML5 output). Any help would be much appreciated, thank you.

I experienced this issue with Captivate 8 and Photoshop CC...
I eventually realized if the animation has any frames with "no delay" I would get the error. Changing those frames to a 0.1 second delay resolved my issue. Not sure if this is the same bug you are experiencing but it's worth a try!

Why is an animated GIF not appearing on my webpage?

I have succesfully built a site that is ready for publication. The client submitted an ad for one of his suppliers that he wants to promote. It is an animated GIF from AVG.
I placed it on the home page. It looks great. It shows up in previews. When I publish the site online, the GIF does not display. If I export the site as HTML and view the files locally, the file appears as it should.
When I view the online version on Firefox, there is no GIF file visible. When I use Chrome to view the site, the GIF is there. The client says for him it's vice versa. Firefox shows the GIF, but Chrome does not.
I did not apply ANY styling to the GIF. It is only placed on the page as is.
I cannot figure this one out. HELP.
The site is located at: http://72.29.127.6/~pcbasics/
I will submit the muse file upon request.

I was wrong, it is not NTFS. According to a 700 mHz eMac running 10.3.9, it is Format: Mac OS Extended (Journaled). And it mounts the desktop on the eMac as well as reading and writing. I can copy files to it and remove them on the eMac.
My powerbook 1.5 gHz on the other hand, still not mounting.
Given this error I will repost this problem under a new subject.
Why would a drive mount an eMac desktop but not a Powerbook?

This particular site may usually only uses these images every once in a while so if no one checks this in the next couple days the images will no longer be there. I created a web archive the site which I could send if this page does go away. The issue does not happen in Firefox or Internet Explorer.

Hi and Welcome to Apple Discussions
I get the same effect as you in Safari. Loaded with no problem in Firefox. Page does have coding errors, which can lead to inaccuracies in how the page is rendered. Safari is much more strict about correct coding than Firefox, adhering to web standards set out by Web Standards Project.

Problem to display Animated Gif from HTML into JEditorPane

I have a problem displaying animated gif that comes from URL (HTML) into JEditorPane.
Let me show you the source I have:
* @author Dobromir Gospodinov
* @version 1.0
* Date: Dec 6, 2002
* Time: 6:47:53 PM
package test.advertserver;
import javax.swing.*;
import java.awt.*;
import java.io.IOException;
public class Test {
     public static void main(String[] args) {
          JFrame frame = new JFrame();
          JEditorPane ed = new JEditorPane();
          try {
               ed.setPage("http://localhost:8200/servlet?key=value");
          } catch (IOException e) {
               e.printStackTrace();
          JPanel panel = new JPanel();
          panel.setPreferredSize(new Dimension(500, 500));
          panel.add(ed);
          frame.getContentPane().add(panel);
          frame.pack();
          frame.setVisible(true);
}Part of the returned from servlet HTML includes an img tag:
<img src="/images/MyAnimatedGif.gif" alt="animated gif comment" width="480" height="50" border="0">Let us assume that MyAnimatedGif.gif has 10 frames and gif is looped - when the 10th is dipslayed it has to display the 1st and so on.
JEditorPane displays frames from 1 to 10 correctly but does not start from the first again. Instead JEditorPane displays a broken image.
I locate where the problem arise:
JEditorPane has an HTMLEditorKit that creates javax.swing.text.html.ImageView instance for every IMG tag.
And here is the problem:
ImageView has an ImageObserver necessary for the asynchronous image download. ImageObserver has the imageUpdate method. But this imageUpdate method is never called with ALLBITS flag raised up. Instead, after the last frame of MyAnimatedGif.gif is downloaded the imageUpdate method is called with flag ERROR raised up. Obviously this is a bug of Sun's implementation. Finaly the flag ALLBITS has to be received for normal end of image observing. But ALLBITS flag does not come.
So, can anybody help me how to load an animated gif within JEditorPane completely.
Thank You in advance,
Dobromir Gospodinov
P.S. If somebody of you wants to debbug what happens within ImageView will have to implement it (and related classes too, because of the limited package visability) borrowing the source from Sun's ImageView.

I'm also having this problem with java 1.4.1 I discovered that some animated gifs work fine, while others stop animating. Running with java 1.3.1 fixed the problem. I'm going to report this as a bug
Here's my code:
import java.awt.*;
import java.io.*;
import javax.swing.*;
public class AnimatedGifTester
extends JFrame
public static void main(String argv[])
throws Exception
new AnimatedGifTester();
public AnimatedGifTester()

StringBuffer buffer = new StringBuffer("<html><body>");
for (int idx = 0; idx < images.length; idx++)
buffer.append("<img src='" + images[idx] + "'>");
buffer.append("</body></html>");
String html = buffer.toString();
// save a copy of the html to open in a browser so we can see what it's
// supposed to look like
BufferedWriter writer = new BufferedWriter(new FileWriter("animatedGifTest.html"));
writer.write(html);
writer.close();
JEditorPane editorPane = new JEditorPane("text/html", html);
editorPane.setEditable(false);
getContentPane().add(editorPane);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setSize(new Dimension(400, 600));
show();
