Problem with Image I/O and applet

I am having trouble using Image I/O to load a PNG image in an applet. I am just using a very basic applet that simply loads the image from a URL and that's it, and the exception I get is -
java.lang.SecurityException: Unable to create temporary file
at java.io.File.checkAndCreate(File.java:1294)
at java.io.File.createTempFile(File.java:1385)
The simple applet is as follows -
import java.awt.image.*;
import java.net.*;
import java.io.*;
import javax.swing.*;
import javax.imageio.ImageIO;
public class CheckImageApplet extends JApplet
public BufferedImage bi = null;
public void init()
URL url = null;
BufferedImage bi = null;
try
url = new URL( "http://localhost/CheckImageSystem/checkimages/backGS.png" );
catch ( MalformedURLException mfue )
try
bi = ImageIO.read( url );
catch ( IOException ioe )
Any thoughts on this exception would be appreciated

It seems the line
bi = ImageIO.read( url );
fails. Can't see anything else. Perhaps this method needs to create a temp image for some reason, and tries to do this at the local harddrive (not allowed). Use getImage(URL, String); instead. ImageIO isn't intended for applets, I think, so you should use the applet methods.

Problems with image on tablet and mobile.

I'm animations with various types of images, and for some reason I am unaware the images do not load right. I realized that when doing a pinch zoom feature of the tablet getting her perfect fix. I tried png and svg. Both give the same problem.Someone has been there?

Appears to be a case of exceeding the original 100% w/h of the images.
Generally the images should be 'prepped' in size (to match the quality when zoomed). So the starting size of the images/icons on the stage should be scaled smaller - then the zoom will factor to the original size. I hope that made some sense.

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?

Copy and Paste Problems with Images

I'm having the strangest problems with images. I copy an image off of the web for one of my art history classes and I go to paste into another program but, whether it's Keynote, Powerpoint, Photoshop, or Graphic Converter, something always goes wrong: the images definitely lose some of their quality, become brighter in appearance, and get jagged on the edges. This is starting to drive me nuts, especially since it never happened in 10.4 on my iBook G4. Any suggestions?

Make it an 8-bit file (Image menu > mode).

My daughter's older Ipod Touch is having a problem with images becoming pixilated when taken from an e-mail and placed into her camera roll. ( She wants to put on Instagram ) Any help?

My daughter's older Ipod Touch is having a problem with images becoming pixilated when taken from an e-mail and placed into her camera roll. ( She wants to put on Instagram ) Any help?

I think that may be a consequence of the email provider she is using. Some services (AOL is one example) inspect and modify email attachments, particularly photos, resulting in reduced resolution compared to the email that was sent.
The iPod does not do this. The resolution of the picture in the email she receives will be identical to what is imported.

I'm having problems with videos, they shake and the images break up back and forth into striped colors, how do I fix this?

I'm having problems with videos, they shake and the images break up back and forth into striped colors, how do I fix this?

1) This is because of software version 1.1. See this
thread for some options as to how to go back to 1.0,
which will correct the problem...

2) This tends to happen after videos. Give the iPod a
minute or two to readjust. It should now be more
accurate.
3) This?
iPod shows a folder icon with exclamation
point
4) Restore the iPod
5) Try these...
iPod Only Shows An Apple Logo and Will Not Start
Up
iPod Only Shows An Apple Logo
I think 3,4, and 5 are related. Try the options I
posted for each one.

I just noticed that one of the restore methods you posted was to put it into Disk Mode First rather than just use the resstore straight off, I Have tried that and seems to have solved the problem, If it has thank you. previously I have only tried just restoring it skipping this extra step. Hope my iPod stays healthy, if it doesnt its a warrenty job me thinks any way thanks again

The errors are here:
          byte buff[]=new byte[(int)file.length()];
          InputStream fileIn=new FileInputStream(aa);
          int i=fileIn.read(buff);
          String conffile=new String(buff); (conffile is a String object containing the image)
and here:
String content ="-----------------------------7d11e410e500f2\r\n"+"Con
ent-Disposition: form-data;"+"name=\"upload\";
filename=\""+aa+"\"\r\n"+"Content-Type:
application/octet-strem\r\n\r\n\r\n"+conffile+"--------
--------------------7d11e410e500f2--\r\n";
printout.writeBytes(content);conffie is sent to the server but
it's non possible to treat binary data as String!
Image files must be sent as byte[] NOT as String ......

Problem with images opened in Photoshop CS 5

Hi, I have a problem with images that I open in Photoshop CS 5. F. ex. I opened
the following image:
The image appears with a purple color in Photoshop. If I hover over the image
with a tool like lasso, it temporarily regains it´s original color. The image mode is RGB Color, 8 Bits/Channel.
I resetted the start settings of Photoshop with the CTRL-Shift-Alt-combination, which had no effect.

The confusion arises from the imprecise error message in the Preferences > Performance dialog box, to wit:
OK, that seems to be open to misunderstanding indeed.
The video card: Citrix Systems Inc. Display Driver.
Could not find a list for CS6 specifically, but the card may fall short.
http://helpx.adobe.com/photoshop/kb/tested-video-cards-photoshop-cs5.html
If I invoke View > Proof Colors, the only thing that changes is that the text in the brackets
Also if you set View > Proof Setup to something different?
Boilerplate-text:
Are Photoshop and OS fully updated and have you performed the usual trouble-shooting routines (trashing prefs by keeping command-alt-shift/ctrl-alt-shift pressed while starting Photoshop, 3rd party plug-ins deactivation, system maintenance, cleaning caches, font validation, etc.)?

Problem with Image.createImage()

Hi all!
I'm writing a simple midlet just to display an image on the screen and I'm having some problems with Image.createImage()
Here is my code
Image bg_img;
ImageItem imageItem1;
imageItem1 = new ImageItem("", null,ImageItem.LAYOUT_DEFAULT, "");
try{
bg_img = Image.createImage("/image.png");
imageItem1.setImage(bg_img);
catch(java.io.IOException e){
e.printStackTrace();
I'm getting an exception on bg_img = Image.createImage("/image.png");
I can't understand what is it...:(
I know for sure that the problem is not "file not found"
Any one can help me???

If you are catching IOException, then u may have problem with ur image path. "image not found on the specified path." if ur image is not in the current directiry then put it into current directory. otherwise, If u are using resouce folder and it is already included into the resouce path, then put ur image in that folder..try this..
Still not get, then please give some detail about ur development toolkit. and ur apllication packaging scheem. are you using ANT?

Problems with image scaling

I'm facing a real problem with image scaling
I've used several algorithms but it all has defects but the most common thing is the out of memory error after several enlargments...
does any one know a solution...
note:
I've used several packages to do so,but I'm looking for a solution from the jdk itself
JAlexscorpio

Did you take into account that the getScaledInstance() -method creates a completly new Image?
So if you use it like in
ImageIcon icon1=new ImageIcon("Blah.gif");
ImageIcon icon2=new ImageIcon(icon1.getImage().getScaledInstance(400,400,SCALE_FAST);
you will end up with 2 different Images which have their own data and memory requirements.
even if you use something like
ImageIcon icon1=new ImageIcon("Blah.gif");
Image i=icon1.getImage();
icon1.setImage(i.getScaledInstance(200,200,SCALE_FAST));
You will need enough memory to store the data for the original image, as well as the data for the scaled
version of the image, at least for the time that it take the JRE to create the scaled version. You never know when the garbage collector kicks in to delete you old data so it could be that this takes some time and until
that moment your memory is not available. If your now doing several of the scaling operations, and there is no chance for the garbage collector to do its work, you will run out of memory.
I hope that might help, if not feel free to post again

I tried updating to os 4.3.3 but Tsed update incomplete due to error. I am now stuck with image of usb and ITunes on IPad. I cannot reboot it or connect to computer. Can anyone help?

I have encountered this problem with my first IPAD2 and brought it back to the Apple Store. They gave me a new one and I used it for a few weeks and my MIC was not working so I decided to try and install the update. I hard wired my laptop this time and again I had the same error. The IPAD2 froze so I went back to the Apple Store and they tried to fix the problem. They could not. So they are going to give me another new one. I asked them what the problem could be and they said it was my computer and I should select the download and not the download and install. But to be honest I do not remember I had that option. When I get my new one, I will see if I get the option to select how I update my IPAD. I also saw a message on this site that suggested closing all security programs before attempting to updat the software. I did ask the apple rep when I returned my IPAD today if the security programs would interfer with the update. They said no, but I will try anything to get the update to work. If you find an answer let me know

Experiencing problem with image display in LR5

I have an intermittent problem with images displaying and exporting in LR. It just began a couple of months ago and is totally random - will do it with RAW (CR2) or JPG. It displays this way in all modules - Library, Develop, Slideshow....The image displays fine in a non-Adobe image viewer (Faststone or Windows Viewer). I've reloaded LR5 and PSCC and is still persists. I know the image file is fine. It also has begun effecting older images that were showing up just fine a while ago. I just loaded about 200 images and maybe 3 or so have this viewing problem in LR & PS. Has anyone else experienced it and have a suggested fix? My graphics card has the latest drivers and shows no problems with other applications. Here is the same image - one a jpg export from Lighroom, the other a save as jpg from Faststone. HELP!

This is almost always a hardware problem, causing corruption of the file. The difference you see between Lightroom and other software is that Lightroom is accessing the full RAW image, while the other software is trying to read the embedded JPG preview.
To figure out exactly what hardware is the problem, you need to try different transmission paths and hardware ... different camera cards, different card readers or USB cables/USB ports, different hard disks, etc. Eventually you should be able to isolate the problem.

I downloaded a new version of firefox. It said it had problems with my norton toolbar and now it doesn't feature it in the window. I'm not that comp savvy. How do I either get the Norton toolbar up or go back to the old firefox? Thank you.

After having yet another problem with my MacBook Pro and having to wipe the drive, I am now unable to sync my iPhones etc without erasing all the music on them. Is there a way around this? I have no other library!

iTunes is a mess! It couldn't find it's own libraries and I was forced to create a new one. Now I don't know where my music is or if any's missing.

How crap is that?
It's not crap at all.
It's not that simple. For example, I've 3500 songs on my MacBook but don't want them all on my phone, so I have to manually select each song again???
There has to be a solution.
Why not simply make a playlist with the songs you want on the iPhone?
and maintain a current backup of your computer.

I keep updating it and it wont let me verify it and I cant get any apps even if they are free, and I just Deleted some apps to make room for my new upate!

The message says: "The payment method has been denied, try another method"
I'm living in the same country and city since I was born, so I don't think the location is the problem.
And yes, I paid with the card a meal in Burguer King today. And nothing more.
