How to generate thumbnail of a image in servlet

hi
could anyone tell me how can we generate thumbnail of a image which is stored in server using servlet

Google for something like java image resize or java create thumbnail. Plenty of examples around.
See also http://today.java.net/pub/a/today/2007/04/03/perils-of-image-getscaledinstance.html
If you are quality conscious to the point that bicubic isn't enough, google for Lanczos algorithm. I don't know of a plug-and-play Lanczos Java implementation. I did one myself (company property, sorry) based on some other language version that google will find for you.

How to generate iMovie thumbnails

Hello,
When i first started my iMovie project, i chose not to generate thumbnails for my video to save me time on the front end, and now I really need to generate them cause i am having trouble matching up my audio and video (recorded on seperate devices). How can I generate thumbnails for my clips? I can't seem to find that option anywhere!
Thanks,
Osprey

You might be able to trick iMovie by temporarily moving that project folder out of the following location:
Mac HD > Users > (your home folder) > Movies > iMovie Projects > (look for the name of the project that blew-up)
Drag that project folder to the Desktop for the time being. Launch iMovie and see if it still tries to create the Project Thumbnails. If it gets past any error messages or other house keeping, you can create a new project. Otherwise, quit iMovie. Drag that project folder from the desktop BACK into your iMovie Projects folder. Try launching iMovie again and see if it gets stuck generating the Thumbnails.

The built in facebook social widgets generate an error "unable to generate thumbnails," all the other social widgets work fine, how can I fix this?

My facebook widgets generate the error "unable to generate thumbnail" - my page is set to public, it also says this even with the adobe muse facebook page. All of my other widgets work fine. Any ideas/help?

Imovie keeps getting hung up generating thumbnails for new events. How do I fix this?

I imported several movies from my miniDV camera without issue. Yesterday I tried to import another movie, only about 30 minutes long to a new event, and the "generating thumbnails for new event" has taken 12 hours and is still not complete. I tried to force quit and reopen the program it just starts the process again upon opening. I went online and downloaded and installed the imovie updates.... still no luck. I can't even use imovie now because when I open it it just goes back to generating thumbnails. Any thoughts? Im new to the Mac, and I just bought this computer 3 days ago and want to love it, but this is frustrating.

What version of iMovie 2011. Make sure you have installed all updates. There has been several updates addressing stability issues. If you have a newer system there were compatibility issues. Hopefully this will fix your issues. I have a new 2012 MBP 13 and works fine. It did lockup (pinwheel) 2x and has been fine.
After the updates running Disk Utility and repair permissions as well. Make sure things are correctly referenced.
Good luck

How do I show multiple rollover images on a page inserted dynamically (pulled out of a sql database

How do I show multiple rollover images on a page inserted dynamically (pulled out of a sql database table) using Dreamweaver’s Repeat Region. Example: I have different products each one associated (through their productID) with two images (one that’s showing in the page and one for the rollover effect) that are pulled from a database using Dreamweaver’s Recordset. So I want to end up with a page containing row after row of images(one for every product).When moused over each image will reveal the second (rollover) image for the same product which in turn can be a link(the image itself ) that when clicked leads to a detailed page with more information about the product the image is associated with. To show row after row with images for the different products in the database table I am using Dreamweaver’s Insert Rollover Image command and then the Repeat Region – I have no problem to complete the steps, to insert the image and the rollover one at once and set the paths so they are pulled dynamically depending on the productID they are associated with .I have also no problem to apply the Repeat Region so not only the first image associated with the first product in the table is shown but all of them-a routine and standard procedure when using the Repeat Region to dynamically generate and display multiple rows of data. However, when I preview the page the rollover effect is lost –the images are shown but when moused over the second image does not show. The problem is caused when the Repeat Region is applied-once again I am allowed to apply it but the rollover stops working, a kind of interference. ANY SOLLUTION PLEASE, ANY WORK AROUND.

I gotta tell you, using multiple images for rollover effects is going to be a big challenge in your dynamic scenario.
If this were my product page, I would use thumbnails with a bit of CSS opacity or filters to desaturate and make them full opacity/color on mouse over. Nice effect with much less bandwidth. Easily done globally with CSS code.
Two examples:

No thumbnails for XPM images

I used to see thumbnails for my xpm images in Finder, however now I no longer see any thumbnails or preview images. How does one fix this?

How long ago was that? Once upon a time various ai and eps files displayed thumbs in Finder, then they went away. And once Photoshop files with an alpha channel displayed correctly (I still can't believe that this was taken away and never returned). Apple giveth and Apple taketh away. AFAIK the best you can do is get a QuickLook generator that handles xpm files and then use it to see thumbs. There's one here:

I tried it and it seems to work without a problem.

Premiere Pro 5.5.2 crashes when generating thumbnails; faults ImageRenderer.dll

Hello all! I'm a new Premiere user. I've been working on a review show, and it's been going great for the last month. A few days ago, however, Premiere Pro started acting wonky. Part of my show involves putting in small clips from other sources, typically 3-4 seconds. With this most recent show, Premiere Pro started crashing left and right without warning. It took me a few days to narrow down the source.
ImageRenderer.dll seems to be crashing when attempting to generate thumbnail images of the sourced clips. Everything else seems to work fine. It seemed to start when I used the Clip Speed / Duration function to slow down a 30fps clip to about 25% speed. I realized later that the clips were at 30fps in a 24fps timeline (the rest of my material is 24fps). Once I changed the clip's speed, Premiere started crashing, perhaps due to how the clip interacted with the timeline. I removed the offending clip, but it seemed that the damage was done. I discovered that if I deleted the source file from the project inventory pane Premiere wouldn't crash.
I just recently discovered that if I collapse the video track of the source clip, Premiere won't generate thumbnails for those clips and thus remains stable. I stress-tested my rig all day yesterday using MemTest86 and Prime95, with no errors. I also uninstalled Premiere Pro, rebooted, and reinstalled from scratch. I still get the ImageRenderer.dll crash when Premiere attempts to generate thumbnails for the clips. So far I do have a workaround (collapse the video track) but I would like to figure out a better solution for it. I even created a new project and re-sourced the clips into a different frame rate.
Any help would be appreciated!

IMovie11 hangs, freezes while generating thumbnails

Often after importing MiniDV tapes using iMovie11 the progress bar for generating thumbnails gets to a certain point and then stops. It will remain this way for over a day unless I Force Quit the application.
The event directory and thumbnail directory of the imported tape do not show any recently created files after a while.
A search on the internet revealed one workaround - delete any zero-byte DV files that iMovie creates and reload iMovie.This worked for a couple of tapes but now I am stuck while importing other tapes.
I am not using Stabilization.
As of this writing, I may have narrowed the problem down to the number of DV files that iMovie creates. For some reason, with those other tapes, it creates almost 2000 such files for a simple 90-minute tape. When I delete over a 1000 of the smallest DV files iMovie will complete the generation of thumbnails.
I have not yet tested what happens if I delete over a 1000 of the largest DV files.
If I import the same tape twice, the two imports will produce a different number of DV files, the difference is in the hundreds but both data sets are still too large for iMovie11 to generate thumbnails from.
I have tried using two different camcorders for importing those other tapes without positive results.
I have a new low-end Mac Pro with the OS present as of Oct of last year (when I bought the computer), 8GB of RAM, 600MB of free disk space, and I use a Firewire adapter to convert the 400 mbps connection coming out of the camcorders to the 800 mbps connection integral to my Mac Pro.
I have tried powering down and back up to remove variables involving the OS and Firewire interface.
I have no other movie projects or events present in iMovie when I conduct my imports.
How do I get iMovie11 to stop hanging, freezing while it generates thumbnails?
Thank you.

Absolutely has to be a bug. This isn't a setting or configuration problem. It might even be a Snow Leopard problem. I had the same problems with A2.1.4 on SL as I do with version A3.0.1. Export hangs seem to happen on images that came from my A2 library that was imported into A3 but originally adjusted in A2. These images were imported from scanned TIFF files. If the adjustment mechanism was flawed in prior Aperture versions then Apple needs to create and distribute a utility that converts these images into something that A3 can use.
I will have to revert to A2 running on Leopard until Apple can get this fixed. If I cannot export, there is no point in running the software. On this discussion thread, we are just trying to fly by flapping our arms.

Generate Thumbnail and Display to Browser from a Servlet

I have the following code working locally generating a thumbnail jpeg to the file system.
My question is how would I do the same in a servlet and display the results to the browser?
I don't necessarily want to save the thumbnail to the filesystem on the server, if I can get
away with it. To sum up, using a servlet I would like to reference a full size image (jpeg) on the filesystem and dynamically build a thumbnail in memory and display in via the browser. Can this be done? Help would be greatly appreciated.
import java.awt.* ;
import java.awt.image.* ;
import java.awt.event.*;
import java.awt.geom.*;
import java.io.* ;
import java.net.*;
import javax.swing.*;
import com.sun.image.codec.jpeg.* ;
public class GenerateThumbnail {
public static void main (String args[]) {
try {
// Load normal-sized file
InputStream in = new FileInputStream("test.jpg");
JPEGImageDecoder dec = JPEGCodec.createJPEGDecoder(in);
BufferedImage inImg = dec.decodeAsBufferedImage();
// Scale down to half the size
AffineTransform xform = AffineTransform.getScaleInstance(0.3,0.3);
AffineTransformOp xformOp = new AffineTransformOp(xform,AffineTransformOp.TYPE_BILINEAR);
BufferedImage outImg = new BufferedImage(150,112, BufferedImage.TYPE_INT_RGB);
xformOp.filter(inImg, outImg);
// encode the reduced image
OutputStream out = new FileOutputStream("thumbnail.jpg");
JPEGImageEncoder enc = JPEGCodec.createJPEGEncoder(out);
enc.encode(outImg);
in.close();
out.close();
catch (IOException ie) {}
}

Why don't you just have the servlet send out the following HTML:
<img src="test.jpg" width=150 height=112>
Of course the full-sized test.jpg will be downloaded by the browser, but the display will be limited to the specified width and height!
If this helps, don't forget the Dukes!

PSE6 FLV Share - how to get thumbnails?

Hi,
I have tried all the available templates (that allow video) to publish for the web various video clips (FLV format).
Does anyone know how one can thumbnails to be visible on the album pages so one can select the relevant clip?
At present all one can do is advance through the clips on the player with no knowledge of what the clips are until they play.
Thanks,
Stewart

How to Generate Statistic Graph in Report??

Hi, i am developing an questionnaire program together with 19 question... i am able to get value for each value..
Now my problem is how to generate a statistic graph whenever user can check their report ??
Can anyone help?? Thank you very much......
from bscs

The easy way is to use your values to set the width or height of an image dynamically in HTML, but you can only do bar charts using this method.
For real reports and measures have a look at

How can I exchange all the images in a slide show with new ones

I have 18 slide shows each is a different competition for our camera club. How can I exchange all the images from each slide show with new images as our club competitions commence? I am reluctant to just delete the slide show because I will have set it all back up. I want to leave the size shape and format of the show as is, but just exchange all of the current images with new ones. I am hoping there is a quick way to delete and replace all images for each show? Each slide show has around 40 images and I have 18 shows
thank you for your help

1. Activate "thumbnails" in the configuration panel
2. Select one Thumbnail.
3. Rightclick and choose "Select same"
4. Press "backspace"
5. Open the configuration panel and load the new images.
