Custom Image Renderer

I've created my own loader to load a raster file containing temperatures.
The values are in the range of 260 to 300. I've also stored these numbers as 64 bit reals.
When I use GeoRasterViewer and normalise the data I can see the map of the world.
When I use MapViewer, the image is all blurred on a gray scale.
Am I not seeing the image correctly because of the temperature range and the way it is stored?
My map request is below.
<?xml version="1.0" standalone="yes"?>
<map_request title="GeoRaster" datasource="geotest"
width="500" height="500"
imagescaling="false" antialiasing="false"
srid="8307" format="GIF_STREAM">
<themes>
<theme name="georaster_theme">
<jdbc_georaster_query
georaster_table="temperature" georaster_column="geo_field"
raster_table="rasterstorage" raster_id="1"
srid="8307" datasource="geotest" asis="false">
</jdbc_georaster_query>
</theme>
</themes>
</map_request>

Currently MapViewer does not normalize rasters cell values and that is probably why they are not rendered properly by mapviewer. We will implement this enhancement in a future version.

Datagrid Image Renderer Broken in CS SDK but not Flex project

Within a Photoshop Extension, I have a DataGrid which has an inline custom image renderer whose dataprovider is an ArrayCollection called "photos" representing a list of photos and some metadata properties. One of the properties "fileName" is concatenated with a path to a thumbnail image such as source="{'LR_AUTO/imported/thumbs/' + data.fileName}".
The dataprovider is bound to a LCDS DataService. When the extension is first launched, the dataservice initializes the dataprovider with the existing values for the "photos" arraycollection. The thumbnail images are correctly shown.
However, when the DataService receives a new row and updates the photos dataprovider, the datagrid's new row shows a broken image for the thumbnail even though the path is correct. I have dumped the photos dataprovider and verified that all information is correct. When I close Photoshop and relaunch it from Flash Builder, once again LCDS initializes the photos ArrayCollection and THEN the thumbnail that previously showed as broken show up correctly.
I have a ColdFusion Directory Watcher Gateway that watches a directory where Lightroom auto-imports images from a tethered capture session. When the camera sends Lightroom a new image, the new image is processed by Lightroom and moved to a target directory, and since ColdFusion's Directory Watcher is watching that targeted directory, ColdFusion will create a thumbnail image in a subfolder and notifiy LCDS that of the new image and related metadata.
*** This is the interesting part *** When Lightroom places new images in the target directory, this is propogated to the Photoshop Extension's datagrid, and the new row shows up as described earlier, showing a broken image for the thumbnail. BUT, instead of Lightroom, if I manually copy images to the folder where ColdFusion is watching, then exact same code path is exectuted and in the Photoshop Datagrid the new row appears and THE THUMBNAIL IMAGE shows up correctly.
The difference seems to be only in how the images are put in the original target location. The problem is when Lightroom puts them there, but it works when I put them there as a user.
*** More Interesting Info *** I have the Flex code for the Photoshop Extension duplicated in a standalone, non-CSSDK project using Flex 3.4 which I launch in a browser. I have mirrored the code in the Photoshop extension, but in this manner, the problem does not exist. With plain Flex 3.4 in a browser, whenever LCDS notifies the datagrid of a new photo record, the datagrid's new row ALWAYS shows the thumbnail correctly.
A primary difference in how the thumbnail image is rendered is that in a browser, the Flex 3.4 project accesses the image assets over the network, however, in the Photoshop Extension, the image asset WITH THE SAME RELATIVE PATH is accessed over the local file system.
source="{'LR_AUTO/imported/thumbs/' + data.fileName}"
So in the case of the browser, this path is a relative URL and the image is retrieved over HTTP, however, in the PS Extension, the same path represents a file system path relative to the project folder.
Unfortunately, because the Flash Player (including APE) cannot access BOTH the network and the local filesystem, so I cannot change the Extension to use network access.
** The important part to remember is that when I stop the Flash Builder debug session and close Photoshop, then relaunch the debug with Photoshop, then all the images show up correctly in the Extension.
Your advice is appreciated.
Thank you!

I expected that if my extension uses the local filesystem AND the network that I would get a Security Sandbox Exception as I recently described in this thread:

TableSorter + custom cell renderer: how to get DISPLAYED value?

Hi!
I have a JTable with a custom cell renderer. This renderer translates numerical codes, which are stored in the table model, into textual names. E.g. the table model stores country codes, the renderer displays the name of the country.
Now, having a reference on the JTable, how can I get the DISPLAYED value, i.e. the country name? Is there some method like ....getRenderer().getText()?
Thanx,
Thilo

Well, a renderer can be anything. It may be rendering an image not text so you can't assume a method like getText(). However, since you know the component being used to render the cell you should be able to do something like:
TableCellRenderer renderer = table.getCellRenderer(row, column);
Component component = table.prepareRenderer(renderer, row, column);
Now you can cast the component and use get text.
Another option would be to store a custom class on the table cell. This class would contain both the code and value. The toString() method would return the value. Whenever you want the code you would use the table.getValueAt(...) method and then use the classes getCode() method. Using this approach you would not need a custom renderer. This thread shows how you can use this approach using a JComboBox, but the concept is the same for JTable as well:

Custom Cell Renderer for JList

I'm getting some strange behaviour from my custom cell renderer.
import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;
public class TestRenderer implements ListCellRenderer {
private JPanel jpCell = new JPanel();
public Component getListCellRendererComponent
      (JList list, Object value, int index, boolean isSelected,
       boolean cellHasFocus) {
    jpCell.add(new JLabel("Render"));
    return jpCell;
import javax.swing.*;
import java.awt.*;
public class TestPanel extends JFrame {
     public TestPanel() {
          JList jlst = new JList(new String[]{"Value", "Value2", "Value3"});
          jlst.setCellRenderer(new TestRenderer());
          JPanel panel = new JPanel();
          panel.add(jlst);
          add(panel);
     public static void main(String[] args) {
          TestPanel frame = new TestPanel();
          frame.setSize(300, 300);
          frame.setLocationRelativeTo(null);
          frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
          frame.setVisible(true);
}As you will see the renderer displays the string several times in each cell depending on which layout manager I use. However, if I replace the JPanel with a JLabel and set the String as text on the label the String is only printed once per cell. I can't see to find the reason for this.

So getListCellRendererComponent returns a component whose paintComponent method is called with the Graphics object of the JList Yes, except that the paint(...) method is called. There is a difference. paintComponent() only paints the component. In the case of a JPanel you would get a boring gray colored component. paint() will paint the component and its children and the Border of the component as well. So you get a much more exiting component.
Read the section from the Swng tutorial on [url http://download.oracle.com/javase/tutorial/uiswing/painting/index.html]Custom Painting for more information.
So the state of the cell is not the state of the cell Renderer Component meaning the image rendered onto the cell only reflects the state of the Cell Renderer Component at the time the cell was rendered.Yes which is why this method should be efficient because repainting is consistently being done for all the cells. For example every time row selection changes multiple rows need to be repainted. Think of this same concept when you use a JTable which also contains multiple columns for each row.
That is why you should not be adding/removing components in the rendering code.
It makes sense except that if this was the case the first version of the Render that I posted should have been rendered first with one "Render" then two then three, shouldn't it?Yes, except that you can't control when or how often the rendering is done. Add the following to the renderer:
System.out.println(index + " : " + jpCell.getComponentCount());You will see that rendering is done multiple times. The JList tries to determine its preferred width. To do this it loops through all the items in the list and invokes the renderer to get the width of the largest renderer. Well the largest width is the last renderer because 3 labels have been added to the panel. So that width becomes the preferred width of the list. Then the GUI is displayed and the list is painted. Every time the renderer is called an new label is added, but after the 3rd label there is no room to paint the label so it is truncated.
Change your code to the following:
//add(panel);
add(jlst);Now change the width of the frame to see what happens.
Given all the help you have received, I expect to see many "helpfull answers" selected as well as a "correct answer" (if you want help in the future that is).

Custom Cell Renderer / Video garbage on "refresh"

I have created a custom Cell Renderer for my JTable. When the application in which this JTable is displayed, is moved into the background and then brought back "front", The application does not redraw itself completely.
I am able to see the information contained in the JTable but none of the surrounding components. When I do a mouse click on any of the background of the surrounding panel, nothing happens.
In order to get the entire Panel/View/all visible components to refresh themselves, I have to click on aother component (example would be switching to a different panel of the tabbed pane.)
This only happens when I have a JTable with this particular Renderer showing. Any other panel or JTable not using this Renderer refreshes completely.
Here is my Cell Renderer most of which I borrowed extensively from info posted in these forums:

Here is an entire example that shows the situation of the Frame (in this case) not updating/refreshing all of it's components when regaining focus.
To simulate the problem, simply move "something"/another window over the sample frame and then move it off. In my case the scrollbar and the headers do not reappear until I have selected a row and scrolled the table.
Here is the example code:
import javax.swing.*;
import javax.swing.table.*;
import javax.swing.border.*;
import java.util.*;
import java.awt.*;
import java.awt.event.*;
public class MultiLineCellExample extends JFrame {
MultiLineCellExample() {
    super( "Multi-Line Cell Example" );
    DefaultTableModel dm = new DefaultTableModel() {
      public Class getColumnClass(int columnIndex) {
        return String.class;
    dm.setDataVector(new Object[][]{{"aa aa aa aa aa\naa aa aa aa aa\naa aa aa aa aa","b","c"},
                                    {"A","B","C\nC"},{"x","y","z"}},
                     new Object[]{"1","2","3"});
    JTable table = new JTable( dm );
    table.setDefaultRenderer(String.class, new MultiLineCellRenderer());
    JScrollPane scroll = new JScrollPane( table );
    getContentPane().add( scroll );
    setSize( 400, 130 );
    setVisible(true);
public static void main(String[] args) {
    MultiLineCellExample frame = new MultiLineCellExample();
    frame.addWindowListener( new WindowAdapter() {
      public void windowClosing( WindowEvent e ) {
        System.exit(0);
}And here is the Renderer code:
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;
import javax.swing.border.*;
import java.awt.*;
import java.io.*;
public class MultiLineCellRenderer extends JList implements TableCellRenderer {

        ListCellRenderer renderer = getCellRenderer();

        setCellRenderer(renderer);
    public Component getTableCellRendererComponent(JTable table, Object value,

Custom Property Renderer - class not found error?

Hi,
I am trying to create a custom property renderer in KM - just a basic Hello World for now, as in some of the other threads on SDN.
When I use the renderer for a property in my layout set, nothing is displayed.
My code is as follows:
public class SBPCPropertyRenderer extends AbstractPropertyRenderer
     public Component renderProperty(IProperty property, IResource res, int maxLength)
          throws WcmException

Hi Tom,
I've implemented similar behaviour but with the state of resource. The code is following:
private static final class URLs {
          private static final String BEFORE_APPROVAL = "/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/etc/public/mimes/images/s_s_ledr.gif";
          private static final String APPROVAL = "/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/etc/public/mimes/images/s_s_ledy.gif";
          private static final String PUBLISHED = "/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/etc/public/mimes/images/s_s_ledg.gif";
          private static final String     ARCHIVED = "/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/etc/public/mimes/images/s_s_ledi.gif";
     public Component renderProperty(IProperty property, IResource res, int maxLength){
          Image image = null;
          try {
               IRepositoryServiceFactory factory = ResourceFactory.getInstance().getServiceFactory();
               IURLGeneratorService ug = (IURLGeneratorService)factory.getService(IServiceTypesConst.URLGENERATOR_SERVICE);
               IStatemanagementManager stateManager = (IStatemanagementManager) factory.getRepositoryService(res,IWcmConst.STATEMANAGEMENT_SERVICE);
               IStatemanagementUtilsResource sResource = stateManager.getStatemangementResource(res).getUtils();
               Locale locale = res.getContext().getLocale();
               IState state = sResource.readState();
               if (state.getID().equalsIgnoreCase(States.BEFORE_APPROVAL))
                    image = new Image(ug.createAbsoluteUri(new UriReference(URLs.BEFORE_APPROVAL,null,null)).getPath(), state.getDescription(locale));
               if (state.getID().equalsIgnoreCase(States.ARCHIVED))
                    image = new Image(ug.createAbsoluteUri(new UriReference(URLs.ARCHIVED,null,null)).getPath(), state.getDescription(locale));
               if (state.getID().equalsIgnoreCase(States.APPROVAL))
                    image = new Image(ug.createAbsoluteUri(new UriReference(URLs.APPROVAL,null,null)).getPath(), state.getDescription(locale));
               if (state.getID().equalsIgnoreCase(States.PUBLISHED))
                    image = new Image(ug.createAbsoluteUri(new UriReference(URLs.PUBLISHED,null,null)).getPath(), state.getDescription(locale));
               return image;
          } catch (Exception e) {
               StatePropertyRenderer.log.fatalT(e.getMessage());
               return image;
But you can simply take one of the properties of your resource with the method res.getProperty(<IPropertyName>) instead of state and check the value of this IProperty. I took images from KM but you can also add necessary images to your project and use them.

Data provider problem in custom item renderer

I have a complex, custom item renderer for a list. I add
items that I extracted from an xml to the data provider using the
IList interface. But when displaying the list, the items are all
screwed up. Each rendered item has some parts which are initialized
as different components depending on the values from the xml. This
initialization is called in the item renderer for the
creationComplete event.
The weird thing is that when I output the dataProvider to
check its values, some of the items have internal uids sometimes
and sometimes they don't. If I output the dataProvider right after
I add the items to it, none of them get internal uids. But from the
initialize method, some of them do and some don't.
To make things weirder, sometimes, as I scroll up and down
the list, the dynamic components get all switched up. I'm either
having a problem with internal uids or with the creation policies
for lists. Or it's probably some simpler mistake I have yet to see.
Anyone have any idea where the problem could lie? Any help is
greatly appreciated.

Any successful render must:
1) override the set data property of the component
Further, best practice is to store any data you need in the
override set data(), and call invalidateProperties(). Then do the
actual work in an override commitProperties() function.
The framework is smart about when to call commitProperties
efficiently. set data() gets called much more often.

Reduce size of custom images in Address Book

I love Address Book's wonderful integration with Mail.app, my iPod and even my phone. So, one day I decided to set custom images for almost all of my contacts - copying and pasting images into the fields.
However, afterwards, I realised that my 275 contact address book has ballooned from 2MB to 49.9MB thanks to the pictures. If I export the contacts into a Group vCards, it is an astounding 121.8 MB.
I feel that Apple should've limited the size of the pictures (automatically resize it just as iPhoto does for email and iWeb does for the web). However, this isn't the case.
Thus, my question is:
Is there a script or anything to reduce the size of those custom images? I am not looking forward to deleting the pictures and resizing them before importing them into Address Book. If there is an automated way of resizing the pictures, please let me know!
Thank you very much!

Hi mintchocicecream,
Have a look at this:
http://discussions.apple.com/message.jspa?messageID=2271577#2271577
May be of no help, but sounds like you have larger that necessary files.
I do mot know of any script, short of a photoshop group resize that would work. Certainly nothing in Address Book.
Good Luck
John

Event Handling in JTable Custom Cell Renderer

I have a JLabel as a custom cell Renderer for a column. I want to handle mouse click event for the JLabel rendered in the cell.
I tried adding the listener for the label in the custom cell renderer but it is not working. Any ideas how to handle this problem??
Thanks
S.Anand

If you want to handle the selection of a tree node
1) write a class like:
public class TreePaneListener implements TreeSelectionListener {
// TREE SELECTION LISTENER
public void valueChanged(TreeSelectionEvent e) {
JTree tree = (JTree)e.getSource();
DefaultMutableTreeNode node = null;
int count = 0;
boolean doSomething = false;
if(tree.getSelectionCount() > 1) {
     TreePath[] selection = tree.getSelectionPaths();
     int[] temp = new int[selection.length];
     for(int i =0; i < selection.length; i++) {
// Check each node for selection
     node = (DefaultMutableTreeNode)selection.getLastPathComponent();
     if(node.getLevel()==2) {
// Change this code to take the action desired
     doSomething = true;
2) After creating the tree register the listener
TreePaneListener handler = new TreePaneListener();
tree.addTreeSelectionListener(handler);

Custom Image bullets--is there a way to change the color?

The reason why is I'm trying to use one of the circles and it keeps coming out dark gray, and it needs to be white (on a B&W laser printer). This is for a check list on a church bulletin.
Also, is there a way to upload other bullet images to use?
Thanks!
MacBook Pro 15", CoreDuo 2 2.33 ghz Mac OS X (10.4.9) Cube 450 mhz

You would need to edit the custom image in some other application, such as GraphicConverter.
As for your second issue, Custom Image is the way to set an arbitrary image as a bullet -- what do you mean by "upload"?

Custom Resource Renderer not coming on Implementing Flexible UI Components

HI,
I am using the Sneak Preview NW2004s SP9 with TREX .
I have to modify the search result list as returned by the TREX using the default search, basically have to include a custom Link based on the resource name.
I am trying to run the examples from the Knowledge Management and Collaboration Developer's Guide - "How to Implement Flexible UI Components".
I deployed the par file for the sample application "Using Flexible UI Ready-Mades"
and followed the steps as outlined below:
System Administration>System Configuration>Knowledge Management -->Content Management
1) Under
User Interface->Mapping>Resource Renderer
Created a new mapping for the java class com.sap.km.ui.renderer.SimpleResourceRenderer
2) Then under
User Interface->Settings>Resource Renderer Settings
Created a duplicate of SearchResourceRenderer
and in the copy changed the Resource Renderer to the custom one(as the one mapped in previous step).
In the Search Result layout Set, i changed the Resource Renderer Name to the custom one.
Now i restarted the server.(i tried restarting after almost all the steps )
But my resource renderer is not coming after i execute the TREX Search.The list returned seems to use the default Resource Renderer.
I even tried by making an advanced copy of the Search Layout Set, changed the Resource Renderer name, updated the OTH file(search.oth), Switched on the degugging for the WdfProxy and reloaded the OTH.
Now the new layout Set is being used but still i cannot see the result as per the custom resource renderer.
Morover, if i try to print some message from the resource renderer code(Component render method), it is not printed in the default Trace file.
Please help me in identifying and resolving the problem.
Thanks,
Siddhartha

Hi Detlev,
Sorry for the delay.
We don't want to exlude the folders, we would like keep it, the problem is, instead of appearing the folder name, is displayed the error message and below the actions (details, delete, ).
At first, we thought that could have been an error in the configuration of LayoutSet, but then, we tried on other two environments, with the default LayoutSet configuration and we still get, on the three environments, the same error message.
Any idea?
Thanks and Regards,
John

Need for a Datagrid with variableRowHeight="true" and custom Item Renderer to display exact rows

Hi again, developers:
I'm in a search of a datagrid with certain characteristics:
     - variableRowHeight = "true"
     - only one column
     - each row must have a custom item renderer with possibly different heights, and a fixed width
     - the datagrid must show always every item in the data provider with no vertical scroll bars, what means that the datagrid height must have always the exact height sum of all the item renderers it is displaying.
     - and no extra empty rows must appear in the last positions of the datagrid
The last two requirements are something difficult to achieve... for some reason, empty rows appear at the last positions of the datagrid. I post what i've managed to get:
<mx:Script>
     <![CDATA[
     private function resize():void
                if (dg.dataProvider)
                    var h:Number = dg.measureHeightOfItems( -1, dg.dataProvider.length);
                    dg.height = h;
     ]]>
</mx:Script>
<mx:DataGrid id="dg" width="530" horizontalCenter="0" verticalScrollPolicy="off"
        dataProvider="{dp}"
        wordWrap="true" variableRowHeight="true" showHeaders="false" dataChange="resize()" height="{dg.measureHeightOfItems(-1,dg.dataProvider.length)}" click="Alert.show(dg.rowCount.toString());">
        <mx:columns>
            <mx:DataGridColumn headerText="ID" width="50">
                <mx:itemRenderer>
                    <mx:Component>
                        <mx:TextArea height="{Math.random()*100}" wordWrap="true" backgroundColor="{Math.random() * 16777216}" paddingTop="0" paddingBottom="0"/>
                    </mx:Component>
                </mx:itemRenderer>
            </mx:DataGridColumn>
        </mx:columns>
    </mx:DataGrid>

Thanks Harui, but it doesn't help. If the border is set it will help, but the very big problem is the empty rows that appear at the end of the datagrid... I can't find a way of measuring correctly the height of the itemRenderers!
I'll update this thread if I manage to do it.

How do I use a custom image as a bullet in Keynote 09?

All I need to do is use a PNG file as a bullet in the Master
Everything I find online says there is a Custom Image option but the only choices I see are None, Bullet, Image, Lettered, Numbered.
This should be simple but I have already wasted 2 hours trying to do this.
Please, can someone tell me what I am missing? What am I not understanding about this procedure?

As stated, the problem was that I could not find Custom Image anywhere. I finally figured out that along with the drop down menu for the Bullets there is also a triangle before the word Bullet 7 Lists. THAT is where one finds the Custom Image choices

Loading custom image formats

Hello all.
I am wanting to load a custom image format into my Java application, and am wondering how to do that. I have a few ideas to try but I figure if there is a site out there (or someone with the knowledge), there is no need for me to re-invent the wheel. So hopefully, someone might be able to expedite my learning. :)
The image format I want to read actually contains multiple images, with 1 color palette at the end of the file. I'd like to create a series of (I assume) BufferedImages for all the images contained within the file.
Are there any sites out there that can send me through a quick tutorial on rolling my own images, or can anyone give me a short function to do so?
Thanks so much!

Okay... I failed. I could really use some help in getting this work. Please.
I have a file, which contains 1 or more compressed bitmap images and a palette. I have a small Perl script that will convert the images in the file into multiple bitmap image files, so I know where the data is and I know I have the data locations right. :)
To create a BITMAP, I must reverse the order of the palette (perl function):
sub reversePalette() {
my $output = "";
for (my $i=0; $i < length($_[0]); $i=$i+4) {
$output = $output . substr($_[0], $i+2, 1) . substr($_[0], $i+1, 1) . substr($_[0], $i+0, 1) . chr(0);
return $output;
}For the image data itself, it uses a simple RLE encoding. If I see a 0, I check the next number and "uncompress" the data by adding that many 0's to the output file.
So, what I would like to do is convert my Perl script into a Java class that will take this sprite file and return an array of BufferedImages, which can then be used for whatever.
Any help in this would be greatly appreciated! I can't even figure out how to properly load a valid BMP file manually using WritableRaster and ColorModel. I'm so lost. :(

Range component in custom item renderer

Hi,
I am trying to put a spark Range component into the labelItemRenderer for flex mobile. Everytime I add it I get the error: "Skin for (long directory name for my range component) cannot be found". The custom item renderer is an actionscipt class because I read this is the best way to make them for mobile. I'll put the error in the bottom of the post.
If anyone has any idea why this could be happening or if anyone knows a possible way around this it would be extremely helpful. I basicaly just need a list where each item has a label on side and then a progress bar on the other side.
Thanks.
Here is the full error, ill put a star on the line where the addChild method gets called in my item renderer for the range component.
