Images using Toolkit && Forte

I have a quick question that, for all the Java books I have, is never addressed.
::When loading an image into an application using the Toolkit.getDefaultToolkit().getImage(), what directory is checked for the image (using Forte)? Assuming that the sourcecode directory is different from the where the classes are compiled to (and they are all within a project directory), which one is searched?

Also, assume that no directory is specified within the parameter to .getImage() - only the filename.

How to tell if an Image is loaded using Toolkit.getImage()

If I use Toolkit.getImage(url) it always returns an Image object, no matter if the image located at that url is a correct image or not.
The w/h is always -1, -1 right after loading (since it hasn't been loaded completely of course).
Anyone know how I can tell if a correct image is loaded or not, without adding a MediaTracker?

Why don't you want to use a MediaTracker? It is by far the most convenient way to do what you want to do.

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
BufferedImage requiredImage= new BufferedImage(800,600,BufferedImage.SCALE_SMOOTH);
//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);
mt.addImage(img, 0); // adds image with ID 0
mt.waitForID(0);
}catch(Exception myex)
myex.printStackTrace();
//draw background starting from x=0, y=0 with 800 X 600 dimentions
g.drawImage(img,0,0,800,600,null);
////////// end draw background image
////////// begin draw image1
img=Toolkit.getDefaultToolkit().createImage(image1);
try
MediaTracker mt = new MediaTracker(frame);
mt.addImage(img, 0); // adds image with ID 0
mt.waitForID(0);
}catch(Exception myex)
myex.printStackTrace();
//draw image1 starting from x=10, y=10 with 200 X 200 dimentions
g.drawImage(img,10,10,200,200,null);
//////////// end draw image1
//////begin transparentImage
img=Toolkit.getDefaultToolkit().createImage(backData);
try
MediaTracker mt = new MediaTracker(frame);

Hierarchical keywords and Image Info Toolkit question

I presently use Image Info Toolkit with a controlled vocabulary for keywording and I'm trying to find a way of doing the same thing in Aperture. Here's my present keyword setup:
IIT works by having a cascading set of keyword windows. You can drill down to the desired level of detail, then apply the entire 'tree' to an image by drag and drop eg.
Europe > UK > England > North Yorkshire > Whitby.
All of the words are applied to the IPTC, plus you can assign synonyms EG Europe, EU, EEC.
I've seen in my demo version of Aperture the ability to create the cascading set of keywords, but it doesn't seem to apply all of the branch, just the bottom word. I see the others are greyed out. Does this mean they are not embedded, or would they be applied on any exported images, say for stock library submissions?
I'm pretty impressed with my demo version so far and if I can get a workflow I like, I can see me scrapping IIT and Bridge.
AAny suggestions very welcome.

Set "Referer" when loading an Image through Toolkit

To load an Image using an HttpURLConnection, I use the abstract java.awt.Toolkit.getImage(URL url) method, which is implemented by sun.awt.windows.WToolkit. This method uses the HttpURLConnection to load the Image.
The problem I have, is that I don't know how I can set the HTTP "Referer" request header. There is a method in the HttpURLConnection called setRequestProperty(String key, String value), which I could use, but I can't reach the HttpURLConnection being used to load the Image.
I would consider another way to load Images, but that would mean quite a bit of refactoring. I would prefer not to use Reflection, though.

I did look at the HttpsURLConnection (of which we also have our own implementation), but that still doesn't solve the problem, unfortunately.
Is there maybe another way to load an image from an HttpURLConnection or HttpsURLConnection? If there's a way that I can provide or access the connection being used and still get an Image object, I would be a happy man!

TS failing on Use Toolkit Package

Started to have problems installing Win7 x64 on machines (HP EliteBook 9470) after removing drivers belonging to other package.
Keep on getting these error messages:
C:\_SMSTaskSequence\Packages\S01000FB\Scripts\ZTISCCM.wsf(11, 3) (null): Library not registered.
C:\_SMSTaskSequence\Packages\S01000FB\Scripts\ZTISCCM.wsf(1655, 4) Microsoft VBScript-runtime error: Object needed: 'oUtility.Arguments'
Failed to run the action: Use Toolkit Package.
Incorrect function. (Error: 00000001; Source: Windows)
As stated above, the drivers that were removed belonged to another package (another HP machine), so it should not have affected this package. Or so i thought...
Every HP 9470 now bombs out on Use Toolkit Package, after the step "Setup Windows and ConfigMgr".
Initially i figured this was a driver related error, so drivers for the NIC has been removed and imported again (Intel 82579LM).
I've tried three different file versions, two from HP and one (newer date) from Dell and finally a native driver from Intel (dated from this year) to no avail.
The files are all downloaded fine.
I can ping internal servers and external sites.
When the machine boots up after this failed install, the icon for wireless connection behaves weird:
It shows as if there are wireless networks available but not connected.
Hovering the mouse over, it does say that it is connected and i can reach both internal servers and external websites.
Unplug and replug the network cable results in the icon for cabled network showing up for a few seconds, then disappering again, acting as if there is no LAN card available.
There are no missing drivers (no exclamation marks) in Device manager.
Anyone else seen this or something like it?
This happens on any HP machine we have.

Hi,
Have you found any solution for this?
We have the same problem in our environment.
SCCM 2012 R2 CU1 with MDT 2013
The problem shows itself when deploying Windows 7 x64 with x86 boot image on the HP z420 and HP zBook 14. HP 9470 has not been tested yet. However, everything works fine with x64 boot. I do not want to use the Z64 boot image!
Does anyone have any solution for this?
The error just popped up by itself without us consciously made any changes in the environment. Has worked well previously with the x86 boot image and Win7 x64 on these models before.

I am trying to softproof an image using a CMYK .icc file. I sent an image from LR 5 to PS CC 2014, opened the Camera Raw FIlter, but the hyperlink to access workflow is not showing up in the CR dialogue box... Any ideas why this might be?

Capture an image using the web camera from a web application

Hi All,
Could anyone please share the steps what have to be followed for capture an image using the web camera from a web application.
I have a similar requirement like this,
1) Detect the Webcam on the users machine from the web application.(To be more clear when the user clicks on 'Add Photo' tool from the web application)
2) When the user confirms to save, save the Image in users machine at some temporary location with some unique file name.
3) Upload the Image to the server from the temporary location.
Please share the details like, what can be used and how it can be used etc...
Thanks,
Suman

1) Detect the Webcam on the users machine from the web application.(To be more clear when the user clicks on 'Add Photo' tool from the web application)There's not really any good way to do this with JMF. You'd have to somehow create a JMF web-start application that will install the native JMF binaries, and then kick off the capture device scanning code from the application, and then scan through the list of devices found to get the MediaLocator of the web cam.
2) When the user confirms to save, save the Image in users machine at some temporary location with some unique file name.You'd probably be displaying a "preview" window and then you'd just want to capture the image. There are a handful of ways you could capture the image, but it really depends on your situation.
3) Upload the Image to the server from the temporary location.You can find out how to do this on google.
All things told, this application is probably more suited to be a FMJ (Freedom for Media in Java) application than a JMF application. JMF relies on native code to capture from the web cams, whereas FMJ does not.
Alternately, you might want to look into Adobe Flex for this particular application.

Downloading images used to go automatically to the last folder used to save images, even when reopening Firefox. In just the past few days, possibly coinciding wih the most recent updates, the folder defaults to the 'Downloads' folder. This is most annoyi

Downloading images used to go automatically to the last folder used to save images, even when reopening Firefox. In just the past few days, possibly coinciding wih the most recent updates, the folder defaults to the 'Downloads' folder. This is most annoying. What happened? Internet Explorer 8.0 did the same thing. This was one of the reasons why I started using Firefox to download all images. I went into Tools>Options and it only lets me set another folder. I dont want to set a specific folder I want it to always go to the last folder used. So what gives?
== This happened ==
Every time Firefox opened
== possibly when the most recent updates were installed, a few days ago

Thanks jscher 2000. I guess I didn't make it clear. "It restarts with all the addons activated, and resumes with the tabs that were open before closing it." IE, it's running fine now with all the extensions activated. Everything is OK now.
So something in the Firefox code was causing the bad behavior. It's not essential that I find out what the problem was - I'm just curious. And if anybody else has this same problem, it might be nice to have it corrected at the source.

Create a new Buffered Image using Raster and ColorModel

Sorry , I crosspost this message,because no one reply.
Recently,I write a programme combining C++ and Java .
The C++ part create a array containing image data in form of BI_RGB and biBitCount==32.
The java part create a image using Raster and ColorModel like this:
   static int[] data ;
   DataBuffer db = new DataBufferInt(data, data.length);
   WritableRaster wr =Raster.createPackedRaster(db, 1024,768, 32, null);
   ColorModel cm = new DirectColorModel(32,0xff0000,0x00ff00,0x0000ff);
   img = new BufferedImage(cm, wr, false, null);But it doesn't work .
it report this:
Exception in thread "main" java.lang.IllegalArgumentException: Raster sun.awt.im
age.SunWritableRaster@dff3a2 is incompatible with ColorModel DirectColorModel: r

Help displaying an image using the canvas!!!!!!!!

Hey guys
I don't know whether I am not grasping some concepts well.I have been going mad trying to get the code working
Here is the code
import javax.microedition.midlet.*;

import java.io.*;
* @author Administrator
* @version
public class MyMIDlet extends javax.microedition.midlet.MIDlet implements CommandListener{

if (display == null){
initMIDlet();
protected void pauseApp() {
protected void destroyApp(boolean unconditional)throws MIDletStateChangeException {
exitMIDlet();
public void commandAction(Command c, Displayable d) {
if (c == exitcommand){
exitMIDlet();
protected void initMIDlet() {
display = Display.getDisplay(this);
canvas = new MyCanvas(this);
System.err.println("Canvas instiated succesfully");
canvas.addCommand(exitcommand);
canvas.setCommandListener(this);
display.setCurrent(canvas);
public void exitMIDlet() {
notifyDestroyed();
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
import java.io.*;
public class MyCanvas extends Canvas implements Runnable {
private MIDlet midlet;
private Image offscreen;
private Image currentimage;
private Graphics g;
//MID profile application
/** Creates a new instance of MyCanvas */
public MyCanvas(MIDlet midlet) {
this.midlet = midlet;
try{
currentimage = Image.createImage("/bird0.png");
}catch(IOException e){
System.err.println(e.getMessage());
if (currentimage!= null){
System.err.println("Image create successfully");
}else{
System.err.println("Image not created");
try{
Thread t = new Thread(this);
t.start();
}catch(Execption e){}
protected void paint(Graphics g){
Graphics saved = g;
int x = getWidth();
int y = getHeight();
g.setColor(255,255,255);
g.drawImage(currentimage,x,y,g.TOP|g.VCENTER);
public void run() {
repaint();
I know for a fact that the Canvas class 's paint method is called by the system and not the application. This poses a problem for me because I am not sure how to pass the image to the piant method, so that it can be painted.
When I run the program(using J2ME wtk04), this is the outcome.
Image created succesfully
Canvas instiatiated successfully
null
Here are my questions
1) when is the paint method precisely called by the system?after a reference to the canvas class is created?
2) is it wise to create the image when instiating the canvas class?( initially created the image using a separate thread)-when sould the image be created?
3)how to let the application know when to use the image when painting the display area?
I am just trying the logistics here. It is very crucial to me to understand the bolts of this as the core f my project fouses on the man machine interface development.(For the project, the cilent application is quering for the map using HTTP)
I use a png file of size 161 bytes. Is that too big for testing purposes.
I would all the help that I can get. thanks in advance

1) when is the paint method precisely called by the system?after a reference to the canvas class is created?
After the canvas is set as the current display, and after that, after the repaint() is called.
2) is it wise to create the image when instiating the canvas class?( initially created the image using a separate thread)-when sould the image be created?
It's better to create the image in the very begining of the program e.g. in the midlet initialization. You can call the created image as often as you like later on
3)how to let the application know when to use the image when painting the display area?
you have to tell it :))
you can use if-then, switch, or anything else
and you can use clipping too

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?

I have installed a trial of Adobe illustrator on my macbook pro. I want to trace an image using the custom trace button but can't. Does anyone have any ideas how I could custom trace?

I have installed a trial of Adobe illustrator on my macbook pro. It is the 2014 release of adobe illustrator. I want to trace an image using the custom trace button.
I start a new document. Then I place my scanned pencil/colored pencil drawing, in to the document. I have tried scanning and then placing it as a jpeg, bitmap, and tiff file. I have tried scanning and then placing it, in color and in black and white. The scan mode I use is flatbed. Adobe illustrator allows me to select the default button and one of eleven preset buttons (e.g high fidelity photo), but it does not allow me to click the custom trace button. The custom trace button is grey while all the other buttons are white.
Does anyone have any ideas how I could custom trace?

It seems pointless to adjust it afterwards because it is then only a couple a pencil lines rather then a full drawing. And how do I adjust it afterwards? Would I do this using the different buttons under the window button?

How to print uspto patent images using Safari and Quicktime

3/18/06
Do you want to know how to print US patent images using Safari? Read on.
When you access the "images" link of a specific patent on the www.uspto.gov/ website using Safari, the page you are viewing is only one small upper left tile of a huge patent image that is not sized to the screen. You can scroll and try to read the page but it's almost impossible. Try to print it out and you only print what's on the screen. Bummer.
The fix:
Place the cursor on the opened image (it may appear blank), hold down the CONTROL key on you keyboard and click on the image. Two instructions come up. Click on the "Save Image to the Desktop" instruction and a DImg.tiff file will be created on your desktop. Click on the .tiff file and it should open in the Preview program, then simply print out the image. Voila!!!!
Click the yellow arrow in the left margin to access page 2 of the patent and repeat the previous instructions to create another .tiff file on your destop. Do every page and you'll have the patent available to print out one page at a time.
You can then rename the files and create a folder for that specific patent so you can access it later without signing onto uspto site.
It's odd that the ever compatible Apple does not provide seamless compatibility to view and print patent images on the US Patent and Trademark Office's website. Where would they be without protecting their own intellectal property? Let's hope the next version of Quicktime includes the appropriate ITU T.6 or CCITT Group 4 (G4) compression language.
Even the "throw it out the Windows" operating system is up to speed on this issue for America's hard working inventors.
Keep on inventing.
