Excellent Blog. Thank You
Small clarification on Step **6) Oracle Home Directory, ...a) Resize the Root Partition**
Ubuntu 11.10 has Gparted available as a Ubuntu software download, DONT use that while trying the above step, instead download the ISO file from http://sourceforge.net/projects/gparted/files/gparted-live-stable/ gparted-live-0.12.0-5.iso (124.6 MB)
Burn that ISO file on a Blank DVD, reboot the Ubuntu , during startup select Boot from DVD Option if not already selected. this will take to Boot Menu Options of Gparted Live then select the first menu option, and this allows to do further action such as Re-sizing .
and once you have chosen and executed step a) . do NOT run step b) also that is "Setup External Storage"
I hope this minor clarification can avoid some confusion

Problem seeing images using Firefox

I have a problem seeing images when using Firefox. I can see them at first, but when i scroll down they dissappear until I get to a certain point on the screen (like when the images are at the top of the firefox screen) then I can see them. Was wondering if anyone knew what the problem could be?

from the system details you've submitted it appears that you have the foxit reader pdf plugin on your system - it's known to cause problems with hotmail since firefox 12. disable it in firefox > addons > plugins until there's an update by foxit which fixes the issue

Grab images using IMAQ without sending frame request

Hello,
When a camera is externally triggered, is it possible to design a *.vi that makes use of IMAQ and grabs images via Camera Link frame grabber without sending frame request signals AND without knowing the external trigger? Just to grab images whenever FVAL, LVAL and DVAL go high. Possible?
Thanks.

Greetings, kcin;
Just to check whether I understood or not, to have the Framegrabber acquire images when the FVAL, LVAL and DVAL lines go high with no other communication between the camera and the host computer? What exactly is the purpose of this endeavor?
Initially, I do not believe it would be possible while using our IMAQ Driver simply due to the way it is designed; I will look into the matter further and inform you of my findings.

Display a grab image using subVI

Hi, i have a problem.. i hope it is easy to solve.
I did a VI using Grab IMAQdx so that i can adquire images from a USB Camera and save a video. It works great and i acquire and save the video. The problem is that when i try to do this VI as a subVI it doesn't work. For the subVI i'm using one terminal the one for the image display. When i run the program i can't see any image (set of images because i'm using grab and it seems like a video), but it seems that the subVI woks because when i open the file where the video was saved, the video is there but i can't see it at the momento on the front panel...
Any suggestions?
Solved!
Go to Solution.

Your main vi will not update the image that you acquire in the sub vi because you would be running your sub vi inside a loop ( I guess). What you can do is create a global variable of Image display indicator and update the indicator inside the sub vi. In the main vi create a seperate while loop and read the global variable and display it in the main vi. Need a better solution? please post your code.
The best solution is the one you find it by yourself

Problem Printing Images Using JAI

I'm using JAI in an application that prints images. My program works fine on my development machine (Windows XP), but when I put it on my Windows Server 2008 r2-64 bit, it crashes for certain images (these are large images of land plats) that go to a particular printer (OCE PlotWave 300) It prints my smaller images that are printing on a variety of printers just fine (images of Mortgages etc..) and it prints everything just fine on my development machine. What could possibly be causing this?

Problem sharing images using Photoshop Album Starter Edition 3.2

Just installed this program and can't seem to email an image. It goes through the processes and the email box pops up with the attachment and when I click on send, it saves and closes. Where does it save and close to and why isn't it sent immediately. Thank you for your help. I am beginning to feel like a dunce.

Hi Mattie,
The role of this program while mailing ends with the popping up of the email box.Any error that occurs afterwards must be due to the mail client.Which mail client are you using?You have mentioned that it saves and closes, so is there any message that is popped about it being saved?
Cheers,

Problem in creating 1 image using differnt images

Dear Fellows I want to create an image by using different images in byte array format. Images may be transparent or normal images. I want final result in byte array. I am using the following technique which is working fine but the problem with this technique is that it takes too much time to create an image. This is because I am using MediaTraker. If I delete the code of MediaTracker then program have undeterministic behavior i.e, sometimes it create the final image properly and sometimes nothing is displayed in final image.
I need some help from you. If anyone of you know the technique to draw image using different images without using mediaTracker kindly let me know.
Early replies will be appreciated
// here is the sample code which i m using for creating image
byte[] backgroundImage= // read 800 X 600 image from disk and convert it in to byte array
byte[] image1 = // read 200 X 200 image from disk and convert it in to byte array
byte[] transparentImage // read 300 X 300 transparent image from disk and convert it in to byte array
Image img=null;
Frame frame =new Frame();
frame.addNotify();
//creating BufferedImage object to store Final image

//get Graphics of BufferedImage created above
Graphics2D g=(Graphics2D) requiredImage.getGraphics();
///// begin draw back ground image
img=Toolkit.getDefaultToolkit().createImage(backgroundImage);
try
MediaTracker mt = new MediaTracker(frame);

Problem in creating client side PDF with image using flex and AlivePD

I need a favor I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf.I am taking the image inside a canvas . How do i control my images so that they come fit on that pdf file for any image size that i take.
Thanks in advance
Atishay

I am having a similar and more serious problem. It takes a
long time to execute, but even attaching a small image balloons the
pdf to 6MB plus. After a few images it gets up to 20MB. These are
100k jpeg files being attached. The resulting PDF is too large to
email or process effectively. Does anyone know how to reduce
size/processing?

Problem when trying to rename uploaded images using session value

Hi,
I have a form where 9 images are uploaded made into thumb nail size and then stored in a file. What I´m trying to do is rename those thumbnails from their original name to username_0, username_1, username_2 etc for each of the 9 thumbs. The username comes from the registration form on the same page. I have created a session variable for the username and am trying to use that to change to name of the image name, whilst my images are uploading and resizing the name stays as the original and not as the new username_$number. I have pasted relevant code below and would very much appreciate any help with this:

I hope i´ve supplied enough information and look forward to receiving any help or advise in this matter.

Use double quotes here:
$newname = str_replace ('name', '$username_$number', $name);
Change it to this:
$newname = str_replace ('name', "$username_$number", $name);

Problem w/ image item using 9i BLOB field and InterMedia ORDImage Object

Hi,dear all,
I have a problem with image item in Form 6i. Oracle 9i is used as backend DB, and a table contains image data is created for testing:
create table image_test(
id number,
image blob
In Form 6i, there is no problem to create a block for inserting/updating the image record into the database. However, it can not be used to retrieve image (blob field), the image item remains empty after 'execute query', while the id field can be retrieved. When the same table is created in Oracle 8.1.7, and the exact same form can be used without any problem both in inserting and retrieval. It seems that the Oracle 9i does not use the same way to store BLOB column. Has anybody ever encountered this problem? How to retrieve image (BLOB) in Form 6i from Oracle 9i?
I tried to use interMedia ORDImage as the data type in Oracle 9i, that is,
create table image_test(
id number,
image ORDSYS.ORDImage
Same problem, the form can insert record with image, but when retrieving, nothing displayed. Anybody could help! Thanks in advance!

hi!
well working with oracle8i and form6i.
same problem..but i used (instead of blob or clob as datatype..) Long raw..
it can be saved as usual..i mean Commit..
and can be retrieved..using Execute_Query..its working fine..
well if anybody get any other solution..do inform..

Search for images using Keywords Problem.

1) In LR4, Search for images using Keywords (click on arrow next to Keyword).
2) Select image, export to PS6, save as Tif.
3) Tif retains all Keywords when it appears in LR
4) Despite that, image does not show up in the same 'Search for images using Keywords'.
Can anyone help with this, it is frustrating me!

Inconsistency problem with Image preview using ImageServlet -JSP

I have a Servlet that reads Images ( JPG) from file system and sends bites to response,
Code works fine and I can see the Image, Problem is that it is very Inconsistent sometimes I can see image and sometimes I see the red X mark instead of image,
if I refresh the page wih shift key holding, the image shows up.
when the image was obsent I can right click the image and go to properties and see the image path and it was correct.
any one has similar experiences with Images before ?
Servlet code follows.
File f = new File(imgPath);
BufferedInputStream in = new BufferedInputStream(new FileInputStream(f));
// Set all the required header information
response.setContentType("image/gif");
response.setContentLength((int)f.length());
response.reset();
response.resetBuffer();
BufferedOutputStream out = new BufferedOutputStream(response.getOutputStream());
byte[] buf = new byte[1024];
int nRead;
while( (nRead=in.read(buf)) != -1 ){
      out.write(buf,0,nRead);
/ Close up all our resources
out.flush();
in.close();
response.flushBuffer();JSP code in pieces.
<% response.setHeader("Cache-Control","no-cache");
   response.setDateHeader("Expires", -1);

Hi Peter,
Thanks for your e-mail.And sorry for late.
I have changed my activex server in my labview programme.Current
server name is XVideoOCX.I have attached 1 example.Still I am facing
the same problem that I am not getting disply from more than 1 web
cam.So would you be able to advice me,what should I do regarding this
matter.
Actually,This is a part of my M.Sc project.I am under pressure.Peter,Please do me this fevour.
Thanks
Kabir
1 eample from help file:
Video Disply
1. Choose the input mode (Video, Single Image Files, Screen, etc.)
XSetInputMode(0) // This
chooses video as input
2. Choose the video device
XSetVideoInput(0) //
Choose the first available video input device
3. Initialize XVideoOCX
XInit() // Initialize
XVideoOCX
4. Start internal video capture
XStart()
now XVideoOCX should display the live video
5. Stop internal video capture
XStop()
6. Close XVideoOCX
XClose()

Problems reading BMP images using ReadImage function

I am trying to load BMP images using the IMAQ Vision ReadImage function (VB6). The images load as monochrome images.
I use the CWIMAQViewer1.Pallette as a parameter in the command.
Note: The images load fine when using Vision Assistant or other image viewing software.
Any ideas?
Thanks!

Sorry. Wrong forum. I'll repost on Machine Vision forum.

Problem loading image for TrayIcon

This code works great if I'm in Netbeans running my project. No problems.
            //grabbing image for TrayIcon
            String curDir = System.getProperty("user.dir");
            Image image = Toolkit.getDefaultToolkit().getImage
                    (curDir + "\\src\\edunasdesktop\\earth_alert.png");The problem is when I run my jar file from the dist folder in my project folder. The TrayIcon loads just fine,
just with no picture. Do I need to point to a different location or do I need to put the picture elsewhere; or both?
Some pictures I used with the Netbeans GUI Builder on some JLabels are in the same src directory but I used the
Builder to add those pics so I guess I'm a bit unsure on how to do this by hand, as the Builder handled this type situation
in previous occassions.

The [section on icons|http://java.sun.com/docs/books/tutorial/uiswing/components/icon.html#getResource] in the Swing tutorial has information about loading images. The general idea is you use
URL toImage = SomeClass.class.getResource(...);Incendently, if done right then it will work in Netbeans or in a jar. The way you currently have it set the image would have to be in +/src/edunasdesktop/+ within the jar file for the Toolkit to find it.

All grabbed images are NI Test Image

I'm using HP dx7400 and the PCIe 1433 is installed on a full-height PCI Express x16.
But from the manual of dx7400, that x16 slot is remarked for graphic cards:
"One (1) full-height PCI Express x16 slot on PCA (for graphic cards)"
Wondering if my 1433 is not correctly installed and causing the grabbing problem.
Any comments would help.
