How to send picture message using J2ME sms APIs?

Hi,
I experiment with SMS APIs, i successfully send simple text message. now i want to send picture message, how to send picture message using J2ME APIs.
please guide me.
guna.

I experienced in coding sending and receiving sms in J2ME. Besides, I also esperienced in coding reading a binary file in a applicaition jar. But I never done these both together. Hence Im not sure it works or not. Below is the example to open and read a binary file:
InputStream oInputStream = getClass().getResourceAsStream( "/picture.png" );
if(oInputStream == null) {
//File does not exist;
throw new Exception("File not found");
//Read the binary file and copy it to a byte array
byte[] abyPicture = new byte[oInputStream.available()];
oInputStream.read(abyPicture );

How to display dynamic images using Struts

I am storing the image name in bean. I want to use the <html:img> tag to display my images. How can i do that using struts.
Something or sort..
<html:img src=bean:write name="pageEntry" property="pageImg"/>
Thank You

* In your web.xml file, add the struts-html-el.tld definition from the struts\contrib\struts-el\lib directory
* Add this tag library to your JSP page; something like:
<%@ taglib uri="WEB-INF/struts-html-el.tld" prefix="html-el" %>* Refer to the following example:
<html-el:img src="${pageEntry.pagePic}" />* This assumes that pageEntry is a Bean, and pagePic is a bean variable accessed by the getPagePic() method.

Can you guide me how to mirror an image using Photoshop CS4 ME ?

hello guys...
as I was surfing the InDesign forum, I just found this which is exactly like the question I was about to ask, but since I read that it's not that easy to do it with InDesign, I am sure that it's doable by Photoshop, but how ???
any way to do it ???
thank you very much .

Unfortunately I'm not too good for recommending good tutorials, as I'm almost 100% self-taught (experiment, try, fail, try again, succeed, that kind of thing).
A Google search for "create mirrored image using Photoshop" does turn up a lot of tutorial content, e.g., http://www.photoshop911.com/tricks/mirror_image.html
With Photoshop you can do anything to an image given sufficient time and effort.
Enjoy the journey!

How do I load images using nio?

Beyond using the toolkit to load an image, I don't know how to load an image. I looked at the javax.imageio package briefly, but I'm not sure where to start there.
I would like to be able to load images with nio Ii.e. memory map the files) and display them on screen.
Any advice and help would be appreciated.
Thanx
Bill

from java api 1.4
BufferedImage bi = ImageIO.read(File)
BufferedImage bi = ImageIO.read(InputStream)
BufferedImage bi = ImageIO.read(ImageInputStream)
BufferedImage bi = ImageIO.read(URL)

How to display an image using MIDP on Palm?

How can I display an image using MIDP on Palm? The following code works on the Siemens SL45i, but not on Palm:
public class Test extends List
Image image = Image.createImage("/images/test.png");
append("item 1", image);

Have found the exact same problem when trying to display an image (other then the default (null)) in a list, on a Palm.
The image displays correctly on a form, but when set on an element in the list, it does not display. (mind you this is in both emulator mode and on the real device)
It does not seem to be related to size of the image.
The Sun documetation states, that you should not rely on it been displayed (obviously it's an implementation issue with the Palm, and other devices I have not tried)
But like to hear definitively from Sun though!

How to change the images used in the "Named people" tiles?

After working on adding people/faces for a while, I find that in many cases the image used in the "Named people" tile for a particular person is the worst one possible.
Is there a way to tell Lightroom to use a different image?

Agreed. The people grid looks horrible after a while. I went looking for a way to identify a key tile and couldn't find it.

Anyone how to resize an image using imagereader and imagereadparam?

I want to use imagereaderparam to process the image.
MY code is as follow:
ImageReader reader = _editor.getImageReader();
     try
     if (reader != null)
               int w = reader.getWidth(0);
               int h = reader.getHeight(0);
               ImageReadParam param = reader.getDefaultReadParam();
               //param.setDestination(reader.read(0));
               Dimension d = new Dimension(my_width, my_height);
               param.setSourceRenderSize(d);
               BufferedImage bi = reader.read(0, param);
     } catch (Exception e)
          e.printStackTrace();
This code just not work , and get an exception
java.lang.UnsupportedOperationException: Can't set source render size!
anyone know how to do that ?
coz i dont want to use getScaledImage...

Hi,
Are you just trying to produce a BufferedImage at a smaller size? May I ask why you don't want to use getScaledInstance? I agree with you not to use it. It is slow. Just wondering what your reasons are. If all you need is to take one image and make it a different size, try this:
BufferedImage src = ...
int scale = 0.5f;
int w = (int)(src.getWidth(null) * scale);
int h = (int)(src.getHeight(null) * scale);
// could use TYPE_INT_RGB if there's no alpha in your image
BufferedImage dest = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
Graphics g = dest.getGraphics();
g.drawImage(src, 0, 0, w, h, null);
d.dispose();How does that work for you? It should be pretty quick.

How do I straighten images using Photoshop CS2?

Can someone please tell me how I straighten images like horizons and buildings using Photoshop CS2?
I run the software under Windows XP
Thank you.

What I do is press Ctrl-T which activates Free Transform. I press Ctrl-" which turns on the grid. I can then rotate the file to correct a drooping horizon, or I can Right-Click on the image to activate the contextual menu, and select Skew. In that mode, I can grab a corner and drag it up or down, right or left, to shift or tilt the image.
Another way to level horizons is to use the Measure tool and from the menu, <Image>, <Rotate Canvas>, <Arbitrary>. You use the Measure tool to draw a line from one part of the horizon to another. When you click Arbitrary you'll get a little dialog. Click <OK> and the image rotates. You'll need to deal with cropping next since your image no longer fills the corners.

How to overlap an image using css in my .cfm

Hi, I know this is a little off-topic, but in my gallery.cfm,
I have a couple of rows that have an image in it, I was wondering
how I can use css to put some text over the image? Like for
example, how can I put some red text "Sold out" over toy1.jpg? I
have tried using z-index but that requires some positioning but in
this case there is no positions ? Can someone please help me on
this?
Sample code:
<table align="center">
<tr>
<td>
<img src="images/toy1.jpg" width="128" height="180"
border="0">
</td>
</tr>
<tr>
<td>
<img src="images/toy1.jpg" width="128" height="180"
border="0">
</td>
Thank you,
C

Hope this helps.
<style type="text/css">
.cell {position:relative;}
.productImage {top:0px; left:0px; width:128px; height:180px;}
.soldText {position:absolute; top:30px; left:0px;
font-size:2.0em; color:red; width:100%;
text-align:center;

How to display large image using JAI

dear all,
could anyone tell me how do i display an image which is around
5000x5000 pixels in JAI. I try to use BufferImage to store the image
but JVM throws" out of memory " error while program is running.
thanx a lot!

just a rough estimate, but a 5000x5000 image would require at least 24MB assuming each byte is one pixal, I believe they are 4 bytes per pixel in RBGA format. (5000*5000) = 25,000,000 pixals /1024/1024 = 23.8MB for 1 byte pixals, *4 for 4 byte = 95.3MB. I'm pretty sure that this is how it stores it. Maybe I'm wrong but it certainly explains the situation. assuming you have at least 256MB ramm, run java with -Xmx200M and see what happens.
java -Xmx200M app
or if you have more ramm, like 512, use 450 or 500.

How do I access images used in Tutorials on AdobeTV?

I'm trying to follow the tutorials on AdobeTV to familiarize myself with Illustrator CS6. The instructor uses preloaded artwork, layers and images to teach and I don't know how to follow along without accessing those images. Are they available for download, or included in the CS6 package?

Depends on the tutorials. Not all fiels are avialable to the users, some are stock content from the programs, otehrs may require registration at lynda.com, some are avialable from Adobe Exchange....

Is there an example somewhere that shows how to acquire StillColor images using IMAQ Vision calls?

I need to be able to acquire images from both composite and RGB channels. I am also confused of how to display them and modify display settings as go from color to grayscale to binary.Thanks.

Jerry,
I have attached a CVI example for doing stillcolor acquisition. If you are using LabVIEW, there should also be shipping examples for stillcolor acquisition under labview\examples\imaq\imaq color.llb
To configure your imaq board for stillcolor acquisition, please refer to the following KB
http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/cc743c416e390c008625683f007562c7?OpenDocument
Hope this helps.
