Help plz~ URGENT: Display image icon with specific coordinates
I want to view an ImageIcon with specific cooridnate (ie, I know the coordinate of the top left hand corner, and i know the height and the width of the "want to display part")
how can i make it such that it will onli view the part i want?
for example
i want to display say from (40, 40) (left hand corner) to (90,90) (right hand corner)
ImageIcon thePic= new ImageIcon("theimage.jpg");
ImageIcon newPic= new ImageIcon( XXXXXXXXX);
what should i put at the XXXXXXXXXX part?
Thanks in advance!
Use getSubImage method of BufferedImage. Something like:
Image originalImage = ImageIO.read(imageFile) ;// see ImageIO API
Image scaledImage = originalImage.getScaledInstance(40.40,90,90);
ImageIcon imageIcon = new ImageIcon(scaledImage);ImageIO.read is overloaded for files, inputStreams and URL's so you can choose how to load it.
I'll leave the rest to you

Since I restored my iPod, it displays an icon with an adapter charger and an electrical outlet. So I connected with an AC charger as the demand for more than 48 hours but no change. My iPod no longer recognized in itunes or my computer and functions no longer work. I tried to reset it, Apple appears to leave room for a few seconds later the same icon with an electrical outlet and impossible to put it into disk mode. Help me please I don't know what to do. And forgive me my bad English I speak only French.

Displaying Images along with Drill Drown Results
I'm using MS access 2003 as my data base and CF as the web
language. I cannot find a topic in reference to displaying Images
along with Drill down results. My tables in access have a OLE
object included however I am clueless as how i can display the
images with my drill down results. I just cannot find a link that
talked about this issue already. Does anyone have a link to this
forum topic?College Kid wrote:

Sorry, no link, but I think you want to be looking at the
<cfimage...>
and|or the <cfcontent...> tags. One or both of these
tags should allow
you to deliver the image from the database to the client.
You are doing this in a bit of an unusual, but not unheard of
way. Most
people just store the image file in a handy directory
accessible to the
web server and then store the name|URL to this image as text
in the
database.
But it is definitly possible to server up binary image data
as well.
Though I have never heard of this in conjunction with MS
Access and 'OLE
objects'. I usually hear this discussed in relation to more
enterprise
database management systems and BLOB [Binary Large OBjects]
data fields. -
I have an image
when loaded into my program, i have the getScaledInstance to about half of the size
and then i want to crop on that scaled image icon, how can i do that?
i tried the crop image filter, but it always need to getImage().getSource() which require the cooridnates of the original image (non scaled one)
i do not have the cooridnate of the original image, i just have the scaled image coordinate part for cropping. How can i crop?Hey, here's some code:
URL url = getClass().getClassLoader().getResource("some_image.jpg");
Image rawImage = ImageIO.read(url);
Image bufferedImage = new BufferedImage(X, X, BufferedImage.TYPE_INT_ARGB);
// Perform your scaling here.
bufferedImage.getGraphics().drawImage(rawImage, 0, 0, X, X, X);
MediaTracker tracker = new MediaTracker(this);
tracker.addImage(bufferedImage, 1);
tracker.waitForID(1);
Image cropImage = bufferedImage.getSubimage(X, X, X, X);Is this anymore useful to you?

Hi,
I would like to replace the standard coffee cup window icon with a custom image for a stand-alone Swing application, all packaged as a JAR file. As a quick test, I wrote the following:
package me.swinginfo1;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
public class IconWindow extends JFrame {
public IconWindow() {
this.setSize(300, 200); //set the window size
this.setLocationRelativeTo(null); //centers window on screen
this.setTitle("Window with Icon"); //set the window title
this.setDefaultCloseOperation(EXIT_ON_CLOSE); //end the program when window closed
java.net.URL imageURL = this.getClass().getResource("images/red_circle.png");
this.setIconImage(new ImageIcon(imageURL).getImage());
* Executes Swing window... no arguments.
public static void main(String[] args) {
IconWindow myWindow = new IconWindow();
myWindow.setVisible(true);
When I run this class from the IDE (Eclipse, in this case), the program runs fine, and my icon image appears in the corner of the window as desired. However, when I package the program into a JAR, the JAR will not execute. My method of packaging is simply to use File -> Export -> JAR.
Note: if I comment out the two lines related to the Icon Image, then the JAR executes as expected (but without my custom image icon, of course).
I am concerned that perhaps the resource folder containing the image is not being included in the JAR. Is there an easy way to check this? Or is there something else I am doing wrong?
Thanks!Thanks for the information atmguy. After checking the jar contents, I found that my resource files (the "red_circle.png" in this case) were not being packaged into the jar. It looks like the reason for this was that I had just added the directory to my project "src" directory by hand, rather than importing the files with Eclipse. Thus, when I packaged the jar using Eclipse, it was unaware of the resource files and therefore did not include them in the jar.
Also, I found that in Windows a handy way of quickly viewing jar files is to rename the jar as a .zip, and then just explore the zip file. (As mentioned here: http://en.kioskea.net/faq/sujet-556-to-see-the-content-of-a-jar-file).
The jar now executes as expected. Thanks! -

Urgent: Displaying image in Abstract Portal Component.
Hi all,
In my application form, i am displaying a logo. I saved that logo under /dist/images. and in my form, i am giving the path as src = "/images/logo.jpg". But image is not displaying. Can anyone quickly help me to solve this.Hi,
U can't use the c:\foldernanme\image name as this is not permissible in portal.
Therefore u need to use the following syntax :
"/irj/portalapps/appl name/project name/folder name/image.jpg"
e.g
<img src="/irj/portalapps/com.tsl.portal.runtime.logon/layout/intro_logo.jpg" border="0">
If the answer is helpful please reward with points.

Urgent: Displaying image in JSPPAge in Abstract Portal Component.
Hi all.
In my application, i need to display the image in a table cell. My JSP page is under dist\portal-inf\jsp\ and my image is under dist\images\. I am calling the image from my page using
<td>
<image src = "..\..\images\image.jpg"></td>
and i am trying with the absolute path also i.e., <src = "C:\Programfiles\....">
But image is not displaying.
Can anyone kindly helpme how to rectify this.Hi,
Call it this way:
src="/irj/portalapps/your par file name/project name>/images/image.jpg"
You can't use the absolute path as the file is application is esecuted on the portal server, not from any local machine.
Hope this helped. If it did, kindly consider rewarding points.
Thanks and Regards,

My new iMac with Yosemite displays photo icons with a white border. How can I remove this border?
How can I remove the white border/'frame' around the photo icons, which I store in folders other than iPhoto?
My computer is an iMac 27" (Late 2014 5K Retina display) with Yosemite 10.10.3.
The border does not exist on any photos /images created on my MacbookPro (Lion) or any earlier computers. It appears after importing to the iMac and only then after saving in either Preview or Photoshop Elements.
I have looked in all "Preferences" but could not find how to remove the border.
Any advice will be gratefully received.Thank you for the reply. I wanted to wait awhile in order to ensure that this corrected the issue. For a brief while, it did! However, it did not take long before the screen began once again hijacking my home button presses. This occurs even with Firefox removed from default applications ( triple-checked ).
This never happened before version 35. -

Please Help::How to display a Map with LIsts as Keys and Values using JSTL
Hi,
I need some assistance on how to display a Map in JSP using struts or core JSTL. I have a HashMap which has a List of keys and each key maps to a value of an ArrayList.i.e I have an ArrayList of taxCodes and each taxCode maps to a value of taxDetails which is an ArrayList of details for for that particular taxCode. I have some trouble to display each taxCode then display taxDetails for each taxCode. Here is my code below:

Edited by: aiEx on Oct 8, 2007 6:54 AMhi evnafets,
yes i need a nested for loop.I have tried your advice but my bean properties are not found.Am getting this error:
javax.servlet.ServletException: Unable to find a value for "key_item" in object of class "java.lang.String" using operator "."
I have tried this as stated earlier in the post:I have tried to make the method getItemTaxDetails return a List and get the returned list value as taxDetails. I then tested to display this list on JSP and its displaying fine.
public List getItemTaxDetails(String key_year,String key_office,
String key_client,String key_company,int key_item){
ItemTax taxDetail = null;
List taxDetails = new ArrayList();
List itemTaxCodes = new ArrayList();
Map itemTaxDetails = new HashMap();
Connection conn = null;
Statement stat = null;
ResultSet rst = null;
//get a list of all tax codes of an item with a
//given item number
itemTaxCodes = getAllTaxCodes(key_item,key_year,
key_office,key_client,key_company);
DbConnection dbConn = new DbConnection();
try {
conn = dbConn.getDbConnection(Constants.WEB_JNDI);
stat = conn.createStatement();
for(Iterator taxCodeIter= itemTaxCodes.iterator(); taxCodeIter.hasNext();){
ItemTax itemTaxCode = (ItemTax)taxCodeIter.next();
String taxCode = itemTaxCode.getKey_tax_code();
String select = "SELECT tax_type,tax_value," +
"tax_limit_val FROM "+ Constants.WEB_TABLE +
" WHERE key_item = "+ key_item +
" AND key_year = '" + key_year + "'" +
" AND key_office = '" + key_office + "'" +
" AND key_client = '" + key_client + "'" +
" AND key_company = '" + key_company +"'" +
" AND key_tax_code = '" + taxCode + "'";
rst = stat.executeQuery(select);
while(rst.next()){
taxDetail = new ItemTax();
//records to be displayed only
taxDetail.setKey_item(Integer.parseInt(rst.getString("key_item")));
taxDetail.setTax_value(rst.getString("tax_value"));
taxDetail.setTax_limit_val(Float.parseFloat(rst.getString("tax_limit_val")));
//////other details records ommited//////////////////////////
taxDetails.add(taxDetail);////An ArrayList of taxDetails for each taxCode
* A HashMap which has all taxCodes of an item as its keys
* and an ArrayList of taxdetails as its values.
* I return this for display in a JSP.
itemTaxDetails.put(taxCode,taxDetails);
} catch (SQLException ex) {
ex.printStackTrace();
} finally{
SQLHelper.cleanUp(rst, stat, conn);
//return itemTaxDetails;
return taxDetails;
}And my JSP
taxdetails_list.jsp

View display image BLOB with PHP!
I using..
$consulta = oci_parse($conexao,"select photo from userp where usrph_status = 'A' and id = :didbv");
$didbv = $_POST["id"];
oci_bind_by_name($consulta, ':didbv', $didbv);
oci_execute($consulta, OCI_NO_AUTO_COMMIT);
while (($row = oci_fetch_array($consulta, OCI_ASSOC)) != false) {
$arr = oci_fetch_assoc($consulta);
header("Content-type: image/JPEG");
$result = $arr['PHOTO']->load();
print "<img src='".$arr['PHOTO']."'>";
print $result;
echo $result;
What appears in the result page is:
This image contains errors and can not be displayed.
How to fix this?- With that content type, you should be sending only binary data, not the HTML "<img" text.
- You have both a print and and echo.
Look at script 105 on p.236 of The Underground PHP and Oracle Manual | Homepage -
