Events on Jpeg image

I have a jpeg image of a particular area map which i need to load in my app using swing, is there a way to fire some event when clicked on specific areas on the jpeg image and then highlight that area.
I have googled and tried various ways but still not getting it right
Please if anyone can guide me it would be great help.
Thanks in Advance

I have found the same functionality on ALOV Map [http://alov.org/index.html] The way their applets works i need exactly the same functionality like pan, zoom etc and most importantly events. but they are using shp files and i dont know exactly what they are. As for other things i tried are Flex's ImageViewer, ImageMap form Flexlib but it dosent solve my problem.
The Map is actually going to be a console where depending on the live datafeeds from the database(continuosly updated) the exact location should be activated, like highlighting/blinking without user interference (Like monitoring system). The user will then click the area and any another activity will be triggerd.
Now honestly i'am confused as the project is in java so we need something in java or related to java swing, servlet, applet dosent matter that is why i posted my query here therfore sorry if it hurt someone that is not my intention. I have even gone as far as HDF5 file format but i need something simple.
I again request you to give me some guidlines that i can try and solve my problem.
Thanks in advance

Help with managing RAW and jpeg images and installing iphoto 9

Greetings: Fist, let me make the neophyte apology and plea - I'm sorry, I should have come here first; I didn't and now I need your help.
I have just purchased a macbook pro (still in its box) with updated software for my older imac os x. I have a number of Canon related photo editing programs (that came with my 40D digital SLR) and Adobe photo elements 6 for mac on the imac. Following some erroneous advice I have made a complete mess of the pictures folder's content by trying to delete images directly from that folder (there are now 6000+ images in the folder, many of which are duplicates(?). Most of the images are not tagged or labeled and some have been organized in/by iphoto (I corrupted the iphoto's library structure very early on by disrupting and editing its images - which might explain why iphoto had a difficult time 'finding' and displaying some of my photos). The picture folder now holds jpegs, smallRAW images (a Canon 40D photo format) and various duplicates of the orignal images - (some of the duplicates don't display as images, but as jpeg logos, which, when opened contain duplicate image or are completely black) The first time I downloaded RAW images into iphoto 6 the RAW data displayed as a black image. When shooting in smallRAW on the Canon 40D, the camera produces a jpeg image for 'easy viewing and editing in the camera' but it looks as though iphoto 6 made duplicates of the jpeg and the RAW data and stored them in different locals in the picture file. In an attempt to get the number of images down, I have been trying to delete them from the picture folder. (My daughters both download images rather indiscriminately in hopes of 'editing them on the computer' which inevitably does not happen) and there is a lot of experimental bracketing of images - shooting raw and different Camera formats etc., all of which need to be cleaned up before I proceed.
Sometime in the not-too-distant future I would like to have iphoto 9 running on my imac with a clean library of images and a seamless way of downloading, editing and storing images (including the RAW data).
The macbook pro is for my highschool-aged daughter, who will run iphoto 9 but not have any RAW image data on her system. She would like to copy some of the old iMac's images to put into her own iPhoto 9 library (probably using a disk, email or on-line photo service - ideally, I would like to be able to copy and remove a number of those images from my HD and give them to her for the macbook)
A few questions and queries: Can I 'dis-able' iphoto 6, while I delete images (RAW and jpeg) from the picture file? (and is this even a good idea).
Once I have edited the # of images down to a reasonable size, should I re-launch iphoto 6, rebuild the iphoto library and then update to iphoto 9 or skip v6 and rebuild with v9?
And now for the 'how stupid is this guy question' - I really had planned to purchase an external backup; but between new the macbook, car repairs and braces it has never come to fruition. So, I have never properly backed up my images. What is the bare-bones, least expensive method for me to do this? I'd even consider burning everything to disks if that works. I can't afford the $ to purchase a new external hard drive right now (really). Budget is set aside mid-November for one though.
I've been looking through some other discussion boards and it looks like I'm not the only one having RAW image issues. I know that shooting smallRAW with the companion jpeg is probably not helping things but I take my camera equipment on extended canoe trips - and we like the ease of on-the-spot editing with this format.
Thanks in advance for your help - Mark

Terence, Is the picture folder the primary source for the images or does that data reside somewhere else?
If you gathered them there, then yes.
I really don't want to have to go through 14,000 images looking for the pictures that I want to keep (or is that my only option?).
Only you can decide what you want to keep.
Why does the computer keep making copies of the images and filing them under date and events?
That's how iPhoto works. It's not a problem usually, only you did go in there and make a problem, and now we are trying to fix it.
You advise not to muck around in the picture file via preview,
No I don't. I advise not to much around in the iPhoto Library Folder.
but if I download images through a program other than iPhotos - image capture or adobe aren't I doing that anyway?
Adobe what? Adobe is a software manufacturer who make many excellent applications, you need to be more precise. And no, if you import photos with Image Capture or “adobe” no you are not interfering with the iPhoto Library Folder.
Can you edit a base image file somewhere and remove it from the HD without iphoto making a copy of it and storing it somewhere else?
This is stunningly easy. Don't use iPhoto. Use an image editor.
I want to look the negatives, decide which ones I want and throw the rest away. Can that be done or am I way off course?
Yes, and iPhoto (or similar apps) make this really easy.
Hook up your camera. Import the pics to iPhoto. Go through the imported pics. Trash the ones you don't want. Then process the ones you do. But you must learn how to use iPhoto to do this successfully
To trash: put the pic in the iPhoto trash and empty it. This removes the file from iPhoto and the Hard Disk.
Process it: If you want to use another editor: You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.

Problem displaying CMYK jpeg images

I have a problem with a CMYK jpeg image.
I know that about supported JPEGs in JRE - JCS_CMYK and JCS_YCCK are not supported directly.
And I found here how to load the image:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4799903
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5100094
I used both the suggestions described to load it, but when the image is displayed the colors are wrong, are very different from the one displayed in PhotoShop, for example.
Any suggestion are very appreciated. If it's necessary i can send you the image.

The loading process It takes about 10 seconds, and every repaint it takes the same time.The painting yes, the loading no. It shouldn't take much more time to load the image then an ordinary JPEG. In particular, your now using a "natively accelerated" JPEG image reader, so it should take less time on average to load any JPEG. 10 seconds is absurd. Are you sure your not including the drawing time in that figure?
- Another problem: JAI-ImageIO is not available for MAC OS X platform.This is somewhat true. You can take the imageio.jar file and package it together with your program (adding it to the class path). This will give you most of the functionality of JAI-ImageIO; in particular the TIFFImageReader. You just won't be able to use the two natively accelerated ImageReaders that comes with installing.
Right now, you're using the accelerated CLibJPEGImageReader to read the image. You can't use this image reader on the MAC, so you have to take the approach mentioned in the 2nd bug report you originally posted (i.e. use an arbitrary CMYK profile).
The conversion is too long more than 30 seconds.The code you posted could be simplified to
BufferedImage rgbImage = new BufferedImage(w,h,
            BufferedImage.3_BYTE_BGR);
ColorConvertOp op = new ColorConvertOp(null);
op.filter(cmykImage,rgbImage);But again, 30 seconds is an absurd value. After a little preparation, converting from one ICC_Profile to another is essentially a look up operation. What does,
System.out.println(cmykImage.getColorModel().getColorSpace());print out? If it's not an instance of ICC_ColorSpace, then I can understand the 30 seconds. If it is, then something is dreadfully wrong.
the RGB bufferedImage that i get after the transformation when it is displayed is much more brightThis is the "one last problem that pops up" that I hinted at. It's because some gamma correction is going on in the background. I have a solution, but it's programming to the implementation of the ColorConvertOp class and not the API. So I'm not sure about its portability between java versions or OS's.

Jpeg image loaded with Loader- loadBytes() does not display when app is deployed on remote server

I am loading a JPEG image from the server, using the Loader->loadBytes() and that works when the app is deployed under my local Tomcat server. When I deploy it on other servers the image is not displayed, instead of the image I see II*
On the server side I have java, Spring, BlazeDs and I use RemoteObject on the client.
The code that loads the image looks like below:
private function imageLoadResultHandler(event:ResultEvent):void {
    var result:ArrayCollection = event.result as ArrayCollection
    var bytes : ByteArray = result.getItemAt(0) as ByteArray;
    _loader = new Loader();
    _loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderCompleteHandler);
    _loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, loaderFaultHandler);
    _loader.loadBytes(bytes);
private function loaderCompleteHandler(event:Event):void {
    var loaderInfo:LoaderInfo = event.currentTarget as LoaderInfo;
    var img:Image = new Image();
    img.source = loaderInfo.content;
    myPanel.addChild(img);
<mx:RemoteObject id="ro" destination="imageLoadService">
     <mx:method name="loadImage" result="imageLoadResultHandler(event)" fault="faultHandler(event)" />
</mx:RemoteObject>
Any help with this problem is much appreciated.
Thank you,
Lumi Velicanu

Hi Dmitri,
Thank you for the prompt reply, your question about the jpeg content was a helpful pointer.
I solved the problem, it had nothing to do with flex, it was all on the java side. The image was obtained from converting a TIFF to a JPEG, the conversion was failing and the flex loader was receiveing a tiff and it did not know how to display it.
The java problem was kind of interesting, I'll post it here as an FYI in case anybody cares :
On my server the first writer returned by ImageIO was an instance of JPEGImageWriter and on the other servers was CLibJPEGImageWriter. And it happens that only JPEGImageWrite can write the type of TIFF that we are having.
The fix was to iterate through all the writers and pick the instace of JPEGImageWrite, instead of the first one found.

Backups of raw and Jpeg images

I currently backup my iphoto library via time machine and keep a second copy of another USB HD. However the backup is the iphoto library, how do I back up the raw and jpeg images so that they are not within the library so that I could access them from a non apple pc?
I just would like the added security.
Thanks
Peter

You'll need to export them from the Library.
Select an Event or Album in the iPhoto Window and go File -> Export
In the resulting dialogue you have a number of options:
From the dropdown you can select the Kind to export:
Originals will get you exactly that: the original files. These will be the contents of the Event as per the iPhoto Window.
Current will get you the most recent versions of the files: a mix of edited and unedited pics. Again, the contents as per the iPhoto Window.
Tiff and Jpeg options allow you to export the current versions in those formats and you can the metadata - tiles, keywords, descriptions and locations - to the files on export.
PnG does not have the option to write the metadata as that format has very limited support for it.
There are other options for file size and naming and so on.

Opening New Browser window for click event on an image

hi all,
I want someone to help me out solving the problem of opening
a new browser window on the mouse click event of an image or a
button etc.... The new window would contain the datagrid details
from the main window, but in an expanded form. If at all there is a
solution, I even want to know whether there is anyway for sizing
the poped up window,because I dont want the new poped up window to
cover the entire screen.
For getting better idea of my problem, the best example I
could give is the popup window that appears when we click on the
preview button while posting the message to the forum.
Someone please do help me out in this regard.
Thanks,
amar.

I'd definitely try to use a Flex popup... but the
flash.net.navigateToURL method is a simple way to open a popup
window in a new browser. You can pass any data needed by the new
page using the URLRequest and/or URLVariables. The URL you navigate
to could, of course, be another Flex application if necessary. I
use this only when I need to open a popup window on another site,
or an HTML formatter report or something similar.
Concerning yourself with the size of the popup window may be
a bad design choice also. I, for example, have my browser
configured to open all popups in a new tab regardless of sizing
constraints imposed by the designer. If it is absolutely necessary
for you to have control over the size of your popup window, you
should follow the advice given by others and use a Flex
popup.

I cannot erase alias JPeg images on a memory card so that it will not accept any more which I try to load onto it, yet there are no actual images available if I click on any of them. The error message states that one or more cannot

Cannot delete aliases for JPeg images on a lumix camera memory card even selecting individual images anjd trying to move to trash -error35 one or more items cannot be found. No image available on clicking or if card put back into camera-"no images to disply" Yet if try to add more images, message that card is full! Any suggestions?

Deleting from iPhoto or image capture after import should be fine and shouldn't cause any issues. Deleting from the folder view of finder, can cause issues as the camera can the image is still there. You can try emptying the trash on your mac if you deleted them via the finder, as although you've deleted it, it's only marked as trashed and not actually deleted until you empty the trash - ie it won't relieve the space taken by the files.
If your still having issues after you try this, you may be best formating the memory card. This will wipe all data on it though, so make sure you do copy anything off that yo u want to keep! Format from the camera, so that choosing the format>erase all option from the menu of most cameras.

hedger,
How do you expect anyone to help when we don't know a darned thing about the file, abut your setup, exact version of Photoshop and your OS, machine specs, etc.?
BOILERPLATE TEXT:
Note that this is boilerplate text.
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),
exact versions of your OS, of Photoshop (not just "CS6", but something like CS6v.13.0.6) and of Bridge,
your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,
what error message(s) you receive,
if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
etc.,
someone may be able to help you (not necessarily this poster, who is not a Windows user).
a screen shot of your settings or of the image could be very helpful too.

How to insert a pdf or jpeg image into a blob column of a table

How to insert a pdf or jpeg image into a blob column of a table

Hi,
Try This
Loading an image into a BLOB column and displaying it via OAS
The steps are as follows:
Step 1.
Create a table to store the blobs:
create table blobs
( id varchar2(255),
blob_col blob
Step 2.
Create a logical directory in the database to the physical file system:
create or replace directory MY_FILES as 'c:\images';
Step 3.
Create a procedure to load the blobs from the file system using the logical
directory. The gif "aria.gif" must exist in c:\images.
create or replace procedure insert_img as
f_lob bfile;
b_lob blob;
begin
insert into blobs values ( 'MyGif', empty_blob() )
return blob_col into b_lob;
f_lob := bfilename( 'MY_FILES', 'aria.gif' );
dbms_lob.fileopen(f_lob, dbms_lob.file_readonly);
dbms_lob.loadfromfile( b_lob, f_lob, dbms_lob.getlength(f_lob) );
dbms_lob.fileclose(f_lob);
commit;
end;
Step 4.
Create a procedure that is called via Oracle Application Server to display the
image.
create or replace procedure get_img as
vblob blob;
buffer raw(32000);
buffer_size integer := 32000;
offset integer := 1;
length number;
begin
owa_util.mime_header('image/gif');
select blob_col into vblob from blobs where id = 'MyGif';
length := dbms_lob.getlength(vblob);
while offset < length loop
dbms_lob.read(vblob, buffer_size, offset, buffer);
htp.prn(utl_raw.cast_to_varchar2(buffer));
offset := offset + buffer_size;
end loop;
exception
when others then
htp.p(sqlerrm);
end;
Step 5.
Use the PL/SQL cartridge to call the get_img procedure
OR
Create that procedure as a function and invoke it within your PL/SQL code to
place the images appropriately on your HTML page via the PL/SQL toolkit.
from a html form
1. Create an HTML form where the image field will be <input type="file">. You also
need the file MIME type .
2. Create a procedure receiving the form parameters. The file field will be a Varchar2
parameter, because you receive the image path not the image itself.
3. Insert the image file into table using "Create directory NAME as IMAGE_PATH" and
then use "Insert into TABLE (consecutive, BLOB_OBJECT, MIME_OBJECT) values (sequence.nextval,
EMPTY_BLOB(), 'GIF' or 'JPEG') returning BLOB_OBJECT, consecutive into variable_blob,
variable_consecutive.
4. Load the file into table using:
dbms_lob.loadfromfile(variable_blob, variable_file_name, dbms_lob.getlength(variable_file_name));
dbms_lob.fileclose(variable_file_name);
commit.

How to load a jpeg image in to a database from a flex2 app

Hi,
how ouwld I browse the local fie system, select a jpeg image
and then save
it to a database using flex2?
Anybody know of some sample code that I can look at?
Thamls

Hi Thamis,
Take a look at the flash.net.FileReference class here:
http://livedocs.macromedia.com/flex/2/langref/index.html
This is the built in Flash support for file upload. You'd
handle the upload with a servlet/jsp/etc. server-side component to
save it to disk or as binary data in a database.
Best,
Seth

Converting a pdf document to a jpeg image C#

HI There,
How can I convert a pdf document to a jpeg image using c sharp? I need to do this on a web application. If someone can help me out with some code that would be great.
Sean - thanks in advance

The information provided by Aandi is unfortunately out of date. The Adobe PDF Library is obtained through Datalogics and has a JNI, Java, and .NET interface available. Additionally while the Adobe PDF Library with the .NET interface would provide the functionality you seek it is overkill.
PDF2IMG from Datalogics has a COM component available that can be accessed via C# to convert PDF to most image formats.

java.awt.HeadlessException: >That makes sense. It is saying that you cannot open a JFrame in an environment (the server) that does not support GUIs!
To make this so it will work on the server, it will need to be recoded so that it uses the command line only - no GUI.
What is it exactly that PinkChartFrame is generated an image of? What does it do? (OK probably 'generate a chart') But what APIs does it use (JFreeChart or such)?

Error when exporting to pdf - cannot read a jpeg image, but I do not know which jpeg image.

I have created a document (A5) in Indesign cs6 with 116 pages. Because I would like to print the book I want to export it to pdf. Normally this is no problem for me, but now I got the following error: "Error encountered while reading JPEG image. Image may be damaged or incompatible. Resave the image with different settings and try again." This is quite annoying as my book contains 631 links of which most are .jpg. Does anyone know how I can find out which picture gives the error?
What is remarkable is the following. As it is a very large file InDesign automatically splitted it in subsections (with names like 'A5 V' or 'A5 V3'). To get closer to the problem I tried to export each subsection (all between 3 and 30 pages) to pdf. But somehow I managed to do this, so one might think that there is nothing wrong with the document at all. But when I try to expor the document as a whole again I still get this error about the JPEG image. It takes a couple of minutes (somewhere between 30 and 40% of the exporting) before I get the error.
Is there anything I should have tried which I forgot? I hope anyone can help me with this problem.

If you are able to export as sections it's almost certainly not actually a problem with the image, but a problem of not enough system resources to finish the job. This is not uncommon with large complex PDF exports.
Try rebooting, then immediately open ID and try the export again first thing. If it works, great. If not, you can combine your sections into a single PDF in Acrobat Pro.
