Images on canvas

Hello,
I use Oracle Forms 6i with Oracle 10g Database.
I have one form where placed over than 30 images. Each image have the same When-Mouse-Click trigger.
I took images from database. Each image is a separate block.
When I press mouse button on the first or on the second image item then all is OK. But on all others fires an error FRM-40734.
WHEN-MOUSE-CLICK
declare
v_item_name varchar2(100);
begin
v_item_name := :system.CURSOR_BLOCK||'.form_name';
call_form(get_item_property(v_item_name,database_value));
end;
I think that my form causes this error because of memory problems.
Can anyone help me? :(

Hi again. Here is the description of error which I've found.
FRM-40734: Internal Error: PL/SQL error occurred.
Cause:     A fatal error occurred in PL/SQL during trigger execution.
Action:     Notify the DBA.
Level:     >25
Type:     Error
Can i ask you one question?
Why trigger_block and not cursor_block?
He he, already i asked 2. :)
Thanks for replies.

Place image on canvas

Hi.
I am trying to place image on canvas.
However the image doesn't show!!!!!!!!!!!!! :(
no error and compiles well....
private void AddTile(String image, int startx, int starty, int endx, int endy)
try{
tiles = ImageIO.read(new File(image));
catch(Exception e)
System.out.println("Image not Found");
Graphics2D a =(Graphics2D)tiles.getGraphics();
a.drawImage(tiles, 20,20,20,20,TileCanvas);
if the above function is called the image should be placed on canvas right?
TileCanvas is a canvas, and tiles is BufferedImage.
just in case I'll put my source code followed by this

You have at least two problems.
1) You are mixing AWT and Swing. Instead of using a Canvas you should use either a JComponent or a JPanel.
2) In Swing, drawing such are you are doing should be done within the paintComponent(Graphics g) method using the Graphics provided as an argument to the method.
P.S. I can't test you code because for some reason you feal the need to use a NetBeans specific layout manager.

OutOf Memory Error while saving image of canvas

Hi,
I am facing a weired problem while saving the image of the graphics in Canvas. It's giving me OutOfMemory error. Here is snippet of code:
if(cmd.equals(C.ACTION_SAVE)){
            try {
                FileDialog fd = new FileDialog(frame, "Save ProcessInstance as JPEG", FileDialog.SAVE);
                fd.setFile(processInstance.getProcessDefinition().getName() +processInstance.getProcessOwner() +processInstance.getProcessOwnerId() +".jpeg");
                fd.show();
                String name = fd.getDirectory()+fd.getFile();
                    int w = canvas.getWidth(), h = canvas.getHeight();
                    BufferedImage image = new BufferedImage(w, h,
                            BufferedImage.TYPE_INT_RGB);
                    Graphics2D g2 = image.createGraphics();
                    canvas.paint(g2);
                    g2.dispose();
                    ImageIO.write(image, "jpeg", new File(name));
                } catch (IOException e) {
                    System.err.println(e);
                }

Hi,
I tried to run garbage collector for the same and now its working fine. I want to know is there any drawback of using this approach. I am new to java and waiting for ur expert comments. I added following lines in the above code just below ImageIO.write(image, "jpeg", new File(name));:
         image = null;
                    Runtime r = Runtime.getRuntime();
                    r.gc();

How to save an image from canvas to jpeg2000 format?

good day! i would like some help about jj2000. i wish to save an image from canvas to a jpeg2000 format file. how will i do it using the jj2000? i just need to save it to a file.
please help!!!
thank you in advance!
lrds

I am not familiar with Jpeg2000, but the easiest way I've found to go from Java to a JPeg file is with Java Adavanced Imaging (JAI) package from Sun. Take a look at it and see if it meets your requirements.

Displaying images in canvas one after another

Hi all,
I have a problem displaying images in canvas one after another. I am using for loop and when i run the application, all images run back in the and only finally only the last image gets displayed in the emulator. I also used thread.sleep(). But it din't work.
Here is my code:
// A canvas that illustrates image drawing
class DrawImageCanvas extends Canvas
Image image;
public void paint(Graphics g)
int width = getWidth();
int height = getHeight();
g.setColor(0);
g.fillRect(0, 0, width, height);
String images[]={"paint_2.PNG","radha.PNG","cute.png","design.png","flowers.png"};
for(int i=0;i<images.length;i++)
image = null;
System.out.println("/"+images);
     try
     image = Image.createImage("/"+images[i]);
catch (IOException ex)
System.out.println(ex);
g.setColor(0xffffff);
g.drawString("Failed to load image!", 0, 0, Graphics.TOP | Graphics.LEFT);
return;
if (image != null)
g.drawImage(image, width/2, height/2, Graphics.VCENTER | Graphics.HCENTER);
try
Thread.sleep(5000);
catch(Exception ex)
     System.out.println("the exception is.."+ex);
Help me and Thanks in advance.

See the code below : prefer the use of a Timer and a TimerTask instead of Thread.sleep().
showNotify (from Canvas) is used to launch the timer.

    Image[] tabImage;
    int imageCounter = 0;
    public DrawImage(){

            for (int i = 0; i < images.length; i++)
                tabImage[i] = Image.createImage("/" + images);

Hi ViswAmmu,
>>Please help me out to get transparency for path in canvas to view background image in canvas.
If I'm not misunderstanding, I think you just need to loop through all Canvas.Children and set Opacity property for them:
private void Image_MouseLeftButtonDown_1(object sender, RoutedEventArgs e)
//Loop through all children items
foreach(UIElement v in CanvasPanel.Children)
v.Opacity = 0;
op.Title = "Select a picture";
op.Filter = "All supported graphics|*.jpg;*.jpeg;*.png|" +
"JPEG (*.jpg;*.jpeg)|*.jpg;*.jpeg|" +
"Portable Network Graphic (*.png)|*.png";
if (op.ShowDialog() == true)
ib.ImageSource = new BitmapImage(new Uri(op.FileName));
imgBackground.Source = new BitmapImage(new Uri(op.FileName));
CanvasPanel.Background = ib;

Can anyone explain me how to scale the image in canvas in flash builder 4.6

Can anyone explain me how to scale the image in canvas in flash builder 4.6, Scaling of image in component , can i get some examples .. it should set almost all size screen

Dropping image on canvas causes image to jump.

When I drop an image on a canvas in AIR the image "jumps" a few pixels to several from the current mouse location.
So if the mouse is at location (12, 12) and I drop the image it may appear at (10, 14), or (15, 20), or whatever. It doesn't appear to be a consistent offset like I would expect if this were caused by using global to local mouse position thing (but I'm not ruling that out anyway).
Secondly, when I then drag to move the image on the canvas the drag proxy will again jump many pixels from the mouse cursor.
Here is my mouse down handler:
            private function dragBegin(event:MouseEvent):void
                  var dragInitiator:Image = Image(event.currentTarget);
                var ds:DragSource = new DragSource();
                ds.addData(dragInitiator, "img");
                var dragProxy:Image = new Image();
                dragProxy.source = event.currentTarget.source;
                DragManager.doDrag(dragInitiator, ds, event, dragProxy);
And the drop handler:
        private function dragDropHandler(event:DragEvent):void
               var image:Image = Image(event.dragSource.dataForFormat("img"));
               image.x = event.localX;
               image.y = event.localY;
               UIComponent(event.currentTarget).addChild(device);
What am I doing wrong that is causing this jumping?
Thanks,
-Mark

Hi,
I think the only way to do this is to use a jsp with a servlet, where the servlet would create the image and send it over as a stream, while the jsp would call on the link of the servlet and display that image using the HTML <IMG> tag.
So, if you have a servlet, lets call it PictureServlet.
This is what you would do in your servet:
// create that image and send it over from the doPost/doGet method of the servlet
public void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
response.setContentType("image/jpg"); // set the stream to be a JPEG image
ServletOutputStream sos = response.getOutputStream(); // create the output stream
BufferedImage bImg = createImage(); // this is where you write on your image using canvas and return it as a Bufferedimage
ImageIO.write(bImg,"JPG",sos); // write the image to the stream as JPEG
sos.close(); // close the output stream
public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        doPost(request, response);
    } This is how you would get that image and display it in your JSP.
<img src="../servlet/PictureServlet" name="pic">Note the path might be different, depending on the hierarchy of where jsps and servlets are stored on the server.
I hope this helps,
Val.

How to fit image inside canvas Container?

Hi All,
I want to fit an image inside a canvas.
Making x and y to 0 of image is not working.
My problem is I am rotating image at 90 and I want to save that image. If i save normally it is not taking rotation.
So I am adding that image in a canvas and saving that canvas with rotated image.
Somehow some portion of canvas still remains empty after adding image to it.
Any idea how to perfectly fit image inside canvas?
Or How to rotate image bitmap data with maintainig aspect ratio?
Thank in advance

Mx component don't handle rotation very well. Spark Group should handle it
better.
You may need to set the y to the height of the rotated image (its original
width).

Image on canvas prob...

Is there any way to know that whether an image is present at particular location on canvas or not?
Actually, i have written a code that draws image on canvas and moving it randomly. I have to keep checking how many times the image passes through a rect area at particular location.....
...........Its a part of my project ..Plz help me out!

Make a Rectangle with width and height equal to the moving image dimensions. Move/position the rectangle from your event code and draw the image at its origin (x,y). Then it is a simple matter to check for intersection between this moving rectangle and the target rectangle.

Clear image on canvas

How to clear the image on canvas? I have a big image span the whole screen and I want to put another smaller image now. There is no "clear" method to be called! What I can do is to draw a rectangle. Any suggestion?
Thanks!

The following should clear your screen.
// Clear the whole screen.
g.setColor(255, 255, 255);
g.fillRect(0, 0, getWidth(), getHeight());

Right click top bar to open Image Size/Canvas Size/Info?

I've just upgraded from PS 5 to PS CC. In previous versions I was able to just right click on the top image bar to bring up a dialog box allowing me to access the Image Size, Canvas Size, Image Info, etc... That does not seem to be the case with PS CC, or am I missing a prefence setting that will allow this?
Thanks!

I tried your suggestion but still cannot access that info by right-clicking the bar. I've gone through my preference settings, primarily under the Interface section and enabled and disabled several options but still no luck. It's just habit from many years use and nice to be able to access several common settings I might adjust.
The keyboard shortcuts are fine also, but again habit and if my hand is already on the mouse it's just...or was just a simple click. (Me being lazy)
Thanks for the help and suggestions. If anyone else a suggestion, great!

Why is the Image in Canvas Square?

I have about a dozen video clips in my Sequence - they are all DV/DVCPRO - NTSC, 720x480. The sequence settings are 720x480 NTSC DV (3:2), Pixel Aspect Ratio NTSC - CCIR 601 - DV 720/480 and the Compressor DV/DVCPRO - NTSC.
Question: Why is the image in the Canvas square?
Thanks in advance for any help.
Brian

it looks stretched taller.
I think you have Anamorphic material.
Start a new Sequence. Go to Sequence > Settings and click the Anamorphic checkbox.
Select a clip in the Browser. Press command and 9. Find Anamorphic in the column on the left.
Click next to it in the Clip column to place a check mark there too.
Edit into the timeline.
Does that look better?

For the website you have given the background image it is using is [1] and it is getting set in css of body tag [2]. So Find the css at [3] and modify it OR replace [1] with other image with same file name.
[1]   www.hanwha.com/etc/designs/hanwha/images/bg-body.jpg
[2]
body {
    background: url("images/bg-body.jpg") repeat-x scroll 50% 0 #FFFFFF;
    color: #757373;
    font: 14px/18px Arial,Verdana,Helvetica,sans-serif;
    margin: 0;
    min-width: 979px;
