Preload an image before JWindow appears

is this accomplished with a thread?
threads are the one territory im afraid to wander in, haha.
I have a JWindow that is opening with only one image in it.
However, as it is now the JWindow coems up immediately
and there it is a LONG time before the image appears.
any suggestions? thanks!
i have this as a class variable
static Image image = Toolkit.getDefaultToolkit().getImage("img/MercLogo.jpg");
i open the Jwindow, put in a JPanel then drawImage.

How about not putting the image loading as part of a static field. Instead do something like
public void openWindow() {
java.awt.image.BufferedImage bigImage = javax.imageio.ImageIO.read(resource);
// jwindow stuff
}ImageIO.load is a synchronous method, only returning when the entire image data is bufferred in memory. The Toolkit method returns an asynchronous image which loads its data when requested.

Image as drop-down text link -- image doesn't appear

(Using Robohelp X5)
Wondering if anybody has had anything like this happen before
and can explain it for me???
First line of topic is type <h1>. At the end of the
line I have an icon that is a link to drop-down text.
Here's where it gets weird. I compiled the help and displayed
the .chm. Looked at the topic, the image doesn't appear, but is
clickable (and works properly). Used the 'print' option from the
.chm to print to .pdf. The image appears in the .pdf.
Looked at the code, can't see anything wrong with it.
Back in the wysiwyg editor, selected the last character of
normal text plus the clickable icon, copied and pasted in place (so
now have
<text2><dropdown2><text><dropdown>)
Removed <text><dropdown> (the original content),
edited the code to use the proper 'name' attribute (because it was
modified on the paste), recompiled, ran the .chm, everything
displays properly (the image is there).
Note: I was having similar problems with it earlier, think I
fixed it the same way, and everything was okay for a few compiles,
then started having the problems again.
At this point, as far as I can see, the .html is the *same*
as it was before, but now the image appears in the .chm. Colour me
totally confused :-)
Anybody have any insights as to why this could be happening?
Thanks!

Change what you have now:
a:link {
    color: #4E8E98;
    text-decoration: none;
a:visited {
    text-decoration: none;
    color: #4E8E98;

Bridge: Images don't appear in Content Folder

(iMac OS X 10.5.2 (Leopard); 4 GB Ram; PS CS 3; Bridge 2.1.1.9; Raw 4.3.1)
All my images are on the MacIntosh hard drive under Cover Flow view. In Bridge, there are two main folders that contain images:: Window Documents ( deleted images from a color management program from a external hard drive/PC computer that I previously owned)) and Pictures (images transferred from PC to MAC). Problem: No images appear from the Window Documents Folder in the Content Pane in Bridge. Most images don't appear on the Content Pane from the Pictures folder with the exception of a few file folders. In the Preview Pane (Bridge) there are all sort of weird glitches. Previous to this problem I worked 7 1/2 hours dragging and dropping images from files in the Window Document Folder into selected folders in Pictures and deleting the images to Trash that weren't going to be kept. Everything ended well that day....no problems but the next day when I opened Bridge I couldn't access most of my images. At the bottom left hand corner of Bridge it tells me how many images there are but they don't appear. Summary: What I do know is that the images are on the hard drive, my computer is trying to open them up but something is preventing them from appearing in the Content Pane. Before I reach for that second glass of wine, can you please help? I am so frustrated and don't know where to turn for help in this matter. Thank you so very much. PS. I also can find the images in Finder when I right click on the mouse button on a file. I've tried using Tools>;Cache>Build and Export Cache. Images will appear but after I close Bridge they disappear into their deep dark hole!

Solved the problem myself. I retyped the name of each folder (same name) under Pictures and added a space plus #1 after each folder name. Images appeared almost immediately on the content pane after that was done. Later I will then open up on my hard drive, under Cover Flow, two windows....one from the Pictures Folder and the other one from the Window Documents that contain the images transferred from an old hard drive. I will then select the images I want to keep and drag and drop the images from the Window Documents to the sub-folders in Pictures and that should do it. Attempting to do it from within Bridge will cause the images in Pictures to disappear so this other way is safer. Then I will trash my Window Document folder when I'm done. If anyone has experience this problem this might be a way to see if my solution might work for you. (I formerly had a window system and now have a iMac).

SVG image does not appear in mobile version but does in desktop version

Hi,
I am new to using Muse and have created only one site before in Muse. I have taken screenshots to show the problem I am having.
I have used Illustrator to create the following logo image that I save out as an SVG file:
As you've probably guessed, I have used clipping mask to insert the marbly purple image into the shapes and text (this may be relevant to the problem, I don't know).
I then save it out as an SVG with the following details as advised by Adobe:
Then moving into Muse, I File > Place the SVG file. 'Unable to generate thumbnail' comes up in both desktop and phone versions:
Regardless, I uploaded to FTP post to my website. While the SVG appears perfectly on my desktop browser, it does not show at all on my phone browser:
This is not only happening on my phone, I have visited the same website on multiple phone devices and still the SVG image does not appear. Any ideas why this is happening?
Have I totally missed something about file formats for mobile browser versions in Muse?
Also- in illustrator, I saved the SVG logo for the mobile version as a SMALLER SVG than the one I saved for the desktop version.
Thanks

Use a PNG file. I see nothing in your logo that would warrant using anything else. You're not scaling it, there is no interaction and all you are doing is masking out some data that is pixels already. Pardon me, but using an SVG makes no sense at all. Beyond that one would need to see the file, but my guess would be that the "responsive" setting once again embeds some garbage data. Wouldn't be the first time...

Images will not appear on Stage area of Adobe Flash Professional

I have Adobe Flash Professional CS5.
Yesterday I successfully created an animation.
Later the same day I tried to create another and the images will not appear on the stage.
I loaded in PNG files - which worked the first time - now they will not show up.
I can see their binding boxes on the stage, and move those but the images just do not show up.
When I hit ctrl + enter to preview, I can see the images in the preview movie - just not on the stage working area!
I tried restarting, shutting down, updating my PC, uninstalling programs, loading different file types (jpg), and resaving and reloading the PNG files. I even tried different types of Flash defaults. NOTHING WORKS.
I hope someone can tell me what is wrong this makes no sense!

Before you drag the image from the library to your stage, make sure you insert a blank keyframe (F6) on the layer you are working with, then drag to stage. This worked for me.

Image does not appear across all browsers

On the main page, just below the "Available soon for..." there is an order now button. It only appears with Safari. I've tried Firefox, Chrome and IE and the image does not appear on any of those. The thing that gets me is that the image was there before and worked fine, all I did was make it bigger and relink it, so I'm confused why all of a sudden it doesn't show up.
Thanks in advance for any assistance.

when you say "Re-upload the image", do you mean reinsert it, or re-link it?
Neither.
Re-upload it to the web server from your local hard drive. In DW, click on the image file in the Files panel then click the Up arrow to Put the image to the server.
If that does not work, do as Nancy suggests and re-create the image in your image editor then re-upload.

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Note the timestamps of the BOOT_TIME log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
☞ When posting a log extract, be selective. A few dozen lines are almost always more than enough.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Step 2
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent of each. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
☞ If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
☞ Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

Images won't appear!

This is a rather odd thing that is happening in Apex, I have never seen this before we have tried very many methods.
Here's the story ...
We have installed Apex on our Oracle App Server R3, and we have set up a load balancer. Everything works fine in the application except all of the images in the images/htmldb underlying subdirectories. We did a lot of debugging to see which images were appearing when logging onto Apex. For some ODD reason everything in the images/menu directory appears fine, actually all of the images directory under the images/htmldb do appear fine too ... EXCEPT for images in the underlying subdirectorys of htmldb/builder/, htmldb/icons/, htmldb/misc/ etc.
What is going on?
Here are the methods we have already attempted...
1) Check the dads.conf file, everything looked fine the aliases were set up file for /i/ and /c/, we restarted the server and everything, still no luck. If the images from the menu directory do appear, then the alias shouldn't even be the problem.
2) Manipulated the dads.conf, we manipulated the aliases for /i/ and /c/ and copied the entire htmldb/ directory into the menu directory, just to see if the images would appear and change the /i/ alias to look into the /menu/htmldb/, again no luck.
3) Recopied the entire images directory, we deleted the entire images directory from the server, and re-copied a fresh copy over from Oracle. Just in case the images were corrupt, again no luck.
4) We moved the images from the htmldb/builder directory to the htdocs directory, because this is a global directory, everything should be accessible by the browser, typed into the url, still image not found.
After every step, restarted the http server and cleared the cache from the browser, still no luck.
The only odd thing is that when we commented out ALL the aliases from the dads.conf file, the images from images/menu were still appearing, even after clearing the cache. These image files were being read from somewhere! We even looked at Apex after deleting the entire images directory, and everything did not work (that was expected). I am not familiar with the infrastructure, but something weird is going on here, is there some server cache that needs to be cleared each time or something?
We tried so many methods for hours, please let us know if anyone has come across this dilemma, it shouldn't be rocket science, the images are there ... typing in the direct URL to the images in the images/htmldb/builder directory should let the image appear in the browser, am I not right?
Is there something I am missing?
Any advice is appreciated.
Ann

I'm not real familiar with how alot of the back end stuff works, but we had an issue where we added an image. It displayed OK in Internet Explorer but not FireFox. We had to upload the image into the SHARED COMPONENTS\FILES\IMAGES page. We then had to reference the image like this:
<img src="#APP_IMAGES#holly.png">

Image fails to appear on a jsp if path to jsp is not default

Hi,
Similarly to one of the tutorials, I dragged and dropped an image (edit button) to a jsp page. When doing exactly as the tutorial says, the image shows fine. But after a small modification which is saving the JSP file under the WEB-INF folder
-> html_public/WEB-INF/JSP/x.jsp the image stopped showing. The image fails to appear as if the path to the image was wrong (ie shows a blank square with a small X in it). if I right click this missing image(blank square) on the jsp page and I choose "open ../../images/x.gif then a new window opens with the image showing fine.
Is anyone able to reproduce this error or maybe knows a workaround for this ?
I am using Jdev 10.1.2 on Windows XP.
TIA
Michael

Hi,
I copied the too lines but it gives me the same result as before.
<% String resourcePath = request.getContextPath(); %>
<.img height="21" width="39" src="<%=resourcePath%>/images/button_edit.gif"/>
I dragged and dropped the image to my jsp to make sure I didn't make any syntax errors, but it looks similar ti the above and both give the same annoying error.
<.img height="21" width="39" src="../../images/button_edit.gif"/>
Any ideas?
TIA
p.s. I added the dot after the < character in this post so that the forum program won't treat the statement as html tag.

Please add "resize image before uploading" and "do...

SOME of us do NOT want to send bothersome, huge images over mobile devices just to share a pointless moment with a friend - or an enemy.
Wechat already has this AWESOME feature, so maybe Skype should have one too - as it is so cumbersome to go into another program to resize and save an image before sending it.
Please add a button to have a possibility of sending a low resoluton version of all images and also before downloading an image to check out if it is worth the money and bandwidth.
Sincerely, The Wrath of Diego

You can resize some bitmap, or movieClip, etc. to a new size by making a new bitmapData at the desired size and drawing the source into the new bitmapData. When doing the draw use a Matrix to accomplish the scaling. Something like so:
var newBitmapData:BitmapData = new BitmapData(320, 240);
var m:Matrix = new Matrix();
m.scale(newBitmapData.width / originalBitmapData.width, newBitmapData.height / originalBitmapData.height);
newBitmapData.draw(originalBitmapData, m);

Previewing an image before uploading

Hi,
I would like to upload images in my application and save those uploaded images to one folder in my system, i could do that with any problem. But i have to preview the image before uploading.
How to do this in JSP or either in html?
please help me in doing this..
thanks in advance

Write the image to some temporary location in your server machine. Either public or non-public. If non-public, you could use a servlet to display the image. If the end user has somehow confirmed the preview, then just move that image to the desired permanent location.
Working with file paths isn't going to work. IE is the only browser which is so dumb that it sends the complete client side file path along with the file name. In other browsers you won't know from which client side path the image is been uploaded.

Image does not appear in applet.

I am reading the book, Teach Yourself Java in 21 Days.
There is an example in Ch.11 that shows how to load an image into the applet.
I have tried to use the code provided as is along with an image as defined in the code. I have also uploaded the html, class and image to a folder on the web. Unfortunately, the image does not appear in the applet. The image does have an image that I created using ms paint.
Here is the code I am currently using from the book:
import java.awt.Graphics;
import java.awt.Image;
public class LadyBug2 extends java.applet.Applet {
     Image bugimg;
     public void init() {
         bugimg = getImage(getCodeBase(),
             "ladybug.gif");
     public void paint(Graphics g) {
         int iwidth = bugimg.getWidth(this);
         int iheight = bugimg.getHeight(this);
         int xpos = 10;
         // 25 %
        g.drawImage(bugimg, xpos, 10,
            iwidth / 4, iheight / 4, this);
         // 50 %
         xpos += (iwidth / 4) + 10;
         g.drawImage(bugimg, xpos , 10,
              iwidth / 2, iheight / 2, this);
         // 100%
         xpos += (iwidth / 2) + 10;
         g.drawImage(bugimg, xpos, 10, this);
         // 150% x, 25% y
         g.drawImage(bugimg, 10, iheight + 30,
             (int)(iwidth * 1.5), iheight / 4, this);
}I tried placing the image in an images folder and I also tried changing the code to getImage(getDocumentBase(), "ladybug.gif")
as well as tried getImage(getCodeBase(), "ladybug.gif") in order to try and grab the image from the same directory as the class file and the html file.
The image file's name is: ladybug.gif
The code in the html file:
<HTML>
<HEAD>
<TITLE>Lady Bug</TITLE>
</HEAD>
<BODY>
<P>
<APPLET CODE="LadyBug2.class" WIDTH=1024 HEIGHT=500>
</APPLET>
</BODY>
</HTML>
I have gotten previous applet examples from the book to work. One of them did have an error in the author's code which I fortunately was able to overcome. This time, I am afraid, the error eludes me.
Thanks in advance.
I do see that there is no start/stop/run in this version, but I believe this should still work because of the init. I am guessing that maybe the problem lies somewhere in there.

According to the javadoc:
getImage
public Image getImage(URL url,
String name)Returns an Image object that can then be painted on the screen. The url argument must specify an absolute URL. The name argument is a specifier that is relative to the url argument.
This method always returns immediately, whether or not the image exists. When this applet attempts to draw the image on the screen, the data will be loaded. The graphics primitives that draw the image will incrementally paint on the screen.
Parameters:
url - an absolute URL giving the base location of the image.
name - the location of the image, relative to the url argument.
Returns:
the image at the specified URL.
I am confused as to how to use the name after the url.
Should it read something like:
bugimg = getImage("http://g.jtrusty.com/JavaApplet/", "LadyBug.gif");
EDIT: I still get the same error, cannot find symbol at getImage.

please tell me how can i display and jpg image on JWindow.

BufferedImage img = ImageIO.read(new FileInputStream("img.jpg"));Or better yet, load it from the classpath rather than relying on the file being in a particular directory relative to where your app started.
Change:
new FileInputStream("img.jpg")
To:
getClass().getResourceAsStream("/img.jpg")
And make sure the directory containing img.jpg is included in the classpath.

Preload an image before JWindow appears
