Image (jpeg, gif) display in AWT layout manager

Goodmorning All,
I am looking for some help, a hint on my AWT Layout challenge i have.
Example GUI_1:
=========================
Window border..................[_][x]..
=========================
[label]....|display_area|....[button].
[label]....|display_area|....[button].
...............|display_area|....[button].
...............|display_area|....[button].
...............|display_area|..................
=========================
...........................................[QUIT].....
=========================
I want to
- display a picture in the "display area" of the this GUI
- put labels left of it with some text
- put a couple of buttons right of it, through which i am able to manipulate the image
Questions:
*1. Is it (even) possible to display an (jpeg,gif) image in the "display area" while using a layout manager?*
Surfing over the internet...so far i only have found applet-examples that use the full gui surface of the applet to display an image via the g.drawImage (imagename, x,y); without any gui elements (labels, buttons) beside it.
*2. What kind of AWT gui element do i need at the location of the "display area"?*
Is is possible to use a CANVAS or do i need somethen else? (e.g. glue an image on a button)
*3. Is is possible to display an ANIMATION (series of sequences jpeg, gifs) in the display area?*
I already found out how to locate and load the images (via mediatracker).
Now i need to find a way to "paint" the loaded images in the GUI.
*4. Is this even possible with AWT layout or do i need to switch to SWING layout?*
I have not used Swing yet, cause i'm working my way up through the oldest gui technologie first.
*5. Do know any usefull websites, online tutorials (on awt and displaying images) that can help me tackle my challenge?*
Thank you very much for your hints, tips and tricks

A link as Gary pointed out is the best way to see what the problem may be.
Did you save the image to your working folder and have you defined a site pointing to this folder.
Defining a site helps Dreamweaver track and organize the files used in this site.

If you can't see the image, this means that the path to the image is incorrect.

Need help to create report with jpeg/gif image

Hello,
I need help with creating a form with a special jpeg/gif seal. I never done this Java. Until now, I created all forms with ansi C++ with HP escape characters to draw lines, boxs, and text. This form will contain boxes which is populated with database information read from a text file.
Since this form contains a special seal on the upper right, I don't think it can be done with old fashion ansi C++. How can I create a form with Java and create it as a simple exe to just print the form to a specified printer.
Thanks,
John

Hi,
I am creating a form with boxes (lines and text). What is special about this form is that it has an image jpeg or gif at the top right corner. Is is a state department seal. Up to this form, I had used ansi C++ and print out escape HP character to print out the lines, boxes, and text. I have no idea how to print out the image. I am new to JAVA and only 1 class in it. Is there sample code out there to create this type of form with the image? I need a starting point.
Thanks,
John

How can i convert an image into gif file as jpeg by using com.sun.image.*

please help me to convert an image into gif format. i have used sun's impl com.sun.image.code.jpeg package to convert a buffered image into a jpeg file. is there any implementatioln available from sun to handle gif files.

Many. Try for instance google with 'java image encoders'. Go to the URL http://www.google.com/search?q=java+image+encoders and be amazed of the wonders of modern web search tools.

How to display thumbnail image of file in KM navigation layout

Hi, I'm using a km nav iview to display some files to my users. The files are all images and it would be more useful if the images could be displayed right upfront instead of clicking on the file name and having the page reload with preview.
I am aware of the layout "TreeList preview explorer", does anyone know of another way to add a thumbnail next to the file name just in a new column instead of in the preview area?
Thanks and regards,
Scott

Scott,
Check this http://help.sap.com/saphelp_nw04/helpdata/en/03/bd7440036f6d1de10000000a1550b0/frameset.htm :
Thumbnails
You use the Thumbnails layout profile to display folders that contain images or documents for which thumbnails are supported.

Can assets be images of type jpeg,gif,Tiff,etc... ?

Hi,
I am working on ES2.
I am able to take PDF file as form to the my process. Here my new requirement is   in addition to pdf I need to take all types of images
say jpeg,gif, and Tiff as input to my process. But I am not able to do that bcas Workbench only takes *.pdf as input.
If you have other extensions expect pdf, while   taking the asset into the start activity, I could not find that file in the application.
Please help me in this regard how workbench takes all image files as inputs into the process.
Thanks
Praveen.

Hi Scott,
Thanks for your reply.
Yes   I have to use as image file as form to the process.
I am using Adobe LC ES2.
Let me explian my requirement : I have scanned image   and need to use that image as input to the process i mean image as form to the process.

Please help in this regard.
Thanks

JPEG/GIF image to BASE64

Hi,
I like to convert JPEG/GIF or any type of image into BASE64 format and Viceversa. Can somebody provide me the java code for doing this.
Cheers,
Siva Maranani.

Rather than use an undocumented API, I would suggest a 3rd party library for Base64 encoding such as the one that I wrote:
http://ostermiller.org/utils/Base64.html
It even has several convenience methods for encoding files:
static void      encode(File fIn)
Encode this file in Base64.
static void      encode(File fIn, boolean lineBreaks)
Encode this file in Base64.
static void      encode(File fIn, File fOut)
Encode this file in Base64.
static void      encode(File fIn, File fOut, boolean lineBreaks)
Encode this file in Base64.

Layout manager issue.

I was hoping that someone could shed some light on why one layout manage will allow an applet to be inserted in a class that extends JFrame but not another.
Here is the guts of the problem I have an class that extends applet to display a pie chart. I then have a seperate class that extends JFrame that display two input boxes and a button. When the user enters two fields and clicks draw the pie chart displays working with the two numbers. The JFrame class that works uses the border layout. I change the class to use gridbag, and now only the textboxes display. Can anyone help. Here is the code for the three classes.
This is the applet class....
* File: PieChart.java
* PieChart class is an Swing applet that use a pie chart
* to show the percentage. It is used by PieChartExample
* to show what percetange of a payment actually goes to
* pay interest. There is no error handling in the program.

percent = 1.0;
     public void setPercentage(double pct) {
          this.percent = pct;
public void paint(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g2.setPaint(fg);
drawAnnotation(g2);
drawArc(g2, percent);
public void drawAnnotation(Graphics2D g2) {
          // draw a small green circle
          g2.setPaint(Color.green);
g2.fill(new Ellipse2D.Double(200, 200, 10,10));
// draw a small red circle
g2.setPaint(Color.red);
g2.fill(new Ellipse2D.Double(270, 200, 10, 10));
g2.setPaint(Color.black);
g2.drawString("Interest", 210, 210); // write "Interest" by green circle
g2.drawString("Principal", 280, 210); // write "Principal" by red circle
     public void drawArc(Graphics2D g2, double percent) {
// draw the interest portion
          g2.setPaint(Color.green);
          g2.fill(new Arc2D.Double(10,10,200,200, 0, percent * 360, Arc2D.PIE));
          // draw the rest (principal portion)
          g2.setPaint(Color.red);
          g2.fill(new Arc2D.Double(10,10,200,200, percent * 360, (1-percent)*360, Arc2D.PIE));
This is the JFrame class using Boarderlayout that works.

Ok. It seems I may be wrong and that this may not be a concurrent call issue. I overode the components setBounds and setLocation methods and it appears that an external class is updating the position of these components while layoutContainer is attempting to position them. I can see that the correct positions are being set in the setBounds method, but this is happening after layoutContainer has called getLocation on the components. To be a little more specific, I am using a JLayeredPane to display some overlapping JLabels with images. I have implemented drag and drop on these labels so that dropping one on another swaps the images. The label positions and sizes are not being changed during the drop (I don't want them to move or resize just change images). However, for some reason I have yet to discover, two calls to set bounds are being made on the labels. The first call is relocating the label to the second labels position, the second call is relocating the label back to it's original position. If anyone has any insight on why the label position are changing when I am not explicitly repositioning them please reply. I will post another reply when I have corrected the problem or found a work around for it. I am awarding the dukes to tjacobs1 since he was the only responses I've had so far.

Capture images (JPEG) from IP-Camera

Hey there!
I have been trying to capture images from an IP-Camera. I understand that this has to be done by using a custom DataSource and I have tried many many example found here on the net, but with no results.
I think I've tried every piece of code found here at this forum regarding this subject.. :/
The best I could do was not getting an error while creating a custom DataSource from a BufferedStream..but the when I try to configure/realize the Processor - created with Manager.createProcessor(customdatasource) - it gives me an error which, I think, has something to do with unrecognized content..
I could post all the examples I tried but I think it would be too much of a confusion so...does anyone have a full working example of code to achieve this? WITH the frame grabber class? plizzzzzzzzz?
Thanks,
Edd

I felt Captfoss' solution was inspired and so gave it a go. The following builds a video from an ip cam jpg stream using a version of Sun's JpegImagesToMovie.java. It is hacked together quickly and with scope for improvement, but it works, proves the idea, and is a good example.
Run as:- java JpegImagesToMovie -w 320 -h 240 -f 30 -o file:test.avi

Podcast image no longer displaying in iTunes

My podcast has been in iTunes for around two years, but just within the past week iTunes is not displaying the graphic. The graphic is still there, and the references in the rss.xml have not changed. Here's a link to the xml file:
http://www.thesecularbuddhist.com/rss.xml
The graphic reference in that files is:
<itunes:image href="http://www.thesecularbuddhist.com/images/iTunes_Art.gif" />
Any help would be appreciated, thank you!

I had the same thing happen to me about two weeks ago, poof my image just dissappeared.
I went ahead and emailed the support team about the issue and this was their response:
"Please forward a copy of the image you would like to update your podcast with as well as the iTunes Store URL of your podcast.
To get the iTunes Store URL, right click or option click on the title in iTunes Store.
Please ensure that the image is:
600 x 600 in dimension
PNG of JPEG format
Using RGB colorspace"
I agree with the user above probably a glitch with the Store.

Refreshing image ( and not displaying the one in the cache )

Hello , I made an app with many galleries stored locally but i made another section with a daily image, and this image is located on an ftp server http://XXXXX.com/image.png for example so everyday i upload the new one with the SAME name as the older one
( that is replaced by the newest ) , however the app is always displaying the older one , even if i restart the app , the computer or kill completely the app.
How could i do please?
Could i add something next to the image url (in a gallery module) to make it refresh everytime the app loads?
PS : if you couldn't solve this problem could i put a button to refresh the image?
Thanks
EDIT : I reinstalled my app and changed several times the image and now it's working?
Is it temporarily so this image will be cached and the issue will appear once more or was it a bug?

Hello
I don't believe you can without addressing/changing the way the image is loaded on your server.
You have several options to remove the caching even from files you upload.
You can for example use a .htaccess file in the folder where your image is uploaded
(assuming your webserver is an apache server)
<IfModule mod_expires.c>
# Enable expirations
ExpiresActive On
# Default directive
ExpiresDefault "access plus 1 day"
# Images
ExpiresByType image/gif "access plus 1 minute"
ExpiresByType image/png "access plus 1 minute"
ExpiresByType image/jpg "access plus 1 minute"
ExpiresByType image/jpeg "access plus 1 minute"
</IfModule>
You can also set the header using a loading script in php, asp or whatever language your server supports (e.g. showimage.php?img=blabla.png which allows you to set the no cache header (or limited cache header) in the php header before loading it in your
applications (works also for asp, etc.). Any searchengine will give you some inspirational examples.

Images won't display in Review mode

When I send a draft of a page for review, several of the
images (jpegs and gifs) will not display. Do the images need to be
formatted in a certain way?

When the draft is published, are the images visible
then?
