Display image in specified position

Hello everyone
I wanna know how I can display an image at an specified (x,y) position. I'm totally lost in how doing it.
I have a bmp image of an arrow (which I could convert into bitmap or gif if needed) and I want to display it in an specified place. I have no idea how to do it.
Can someone show me the beginnings?
thanks

java.awt.List you can not.

The "Use custom settings for history" selection allows to see the current history and cookie settings, but selecting this doesn't make any changes to history and cookie settings.

If all History settings are default then the custom settings are hidden and you see "Firefox will: (Never) Remember History".
"Never Remember History" means that Private Browsing is active and "Always use private browsing mode" gets a checkmark.

How to display images from BLOB column via APEX 4.0

Hello,
I did the following in order to display images of two Oracle records on the APEX page. I am using APEX Version : 4.0.1.00.03 , Oracle DB Version : 10.2.0.4.0.
1. Created An oracle table TEST_FORM
with 3 columns
( ID number, MIME_TYPE varchar2(255) , Image BLOB )
2. Inserted two records
10001, image/gif, ( actual image1)
10002, image/gif, ( actual image2)
3. created an Oracle procedure
CREATE OR REPLACE PROCEDURE show_my_form ( p_image_id IN test_form.id%type) AS
l_mime test_form.mime_type%type;
l_length NUMBER;
l_file_name VARCHAR2 (2000);
lob_loc test_form.IMAGE%type;
BEGIN
SELECT mime_type, IMAGE
, DBMS_LOB.getlength (IMAGE)
INTO l_mime, lob_loc, l_length
FROM test_form
WHERE id = p_image_id;
owa_util.mime_header(l_mime, false);
htp.p ('Content-length: ' || l_length);
owa_util.http_header_close;
wpg_docload.download_file (lob_loc);
END show_my_form ;
4. In Apex 4.0
step1. Created an interactive report on a new APEX page
step2. Specified the following in the Region Source
select id, mime_type, '<img src="#OWNER#.show_my_form ?p_image_id=#ID#" />' photo
from TEST_FORM
The column result shows as <img src="CCS.show_my_form?p_image_id=#ID#" />
I am unable to display the column image as a link to a proper image photo.
Could you please advise me if I missed anything ?
Thanks a lot.
Regards
Susanna

Maybe the space you have before the ? is causing issues. there shouldn't be any space.
Your procedure looks to be much the same of one that I have.
Have you granted execute on your procedure?
Also, what version DB are you running? This could be another issue: http://daust.blogspot.com/2006/04/xe-calling-stored-procedures.html
But anyway, you don't need to create your own procedure these days. You could do the following:
in your query, have a column: dbms_lob.getlength(blob) photo ; save, then in column attributes for that column, apply a format mask. There is usually a link below the text box for the format mask - BLOB Download Format Mask, which will help you build the format mask. But it is documented here: http://download.oracle.com/docs/cd/E17556_01/doc/user.40/e15517/advnc.htm#BCGGJHEF

How to upload and display image using bsp application

hi
I just wants to know that
1- how to upload image from BSP page with attachment into sap server .?
2-how to display image in to BSP page(webpage).
thanks

Hello Gupta Prashant,
Just to upload and display an image, import image in MIME repository. Not only still images but also flash files can also be uploaded in the MIME repository. Once you import the image in it, use normal html code for image call;
<img src = "file.jpg/gif" width= height=>
Besides it, if your requirement is to store the image in the database and fetch it based on specified field-name, then you have to go for BLOBs i.e Binary Large Object, using this you can also store images, videos, pdfs, applications in the database.
MBLOB - Medium BLOBs store videos and pdfs,
LBLOB - Large BLOBs store movie files and applications.
You have got 2 ways to use it; some databases store BLOB objects into themselves and some store the path of the BLOB object maintained on the FTP server.
You can also implement it in ABAP;
read the following link and practice the tutorial;
[ Use of MIME Types|http://help.sap.com/saphelp_45b/helpdata/en/f1/b4a6c4df3911d18e080000e8a48612/content.htm]
also check this
[TYPES - LOB HANDLE|http://help.sap.com/abapdocu/en/ABAPTYPES_LOB_HANDLE.htm]
And looking at your question, in order to upload an image, you can make use of FILEUPLOAD tag provided by HTMLB.
Step 1: FILEUPLOAD provides a browse button to choose desired image file.
Step 2: Store that image in database using BLOBs.
Step 3: Retrieve the image using normal select query and display it on the screen.
Hope it helps you,
Zahack

Problem in displaying images stored in Blob variable

Hi all,
I have a requirement where i need to retrieve the image stored in Blob variable in DB and display the image in JSP page.
I have written the below code to achieve this, it works fine
In JSP, I am calling a action in the <img tag
<img src='downloadPhoto.page?method=getPhotoInBytes&accessoryModelPictures.id.accessoryNumber=${photo.id.accessoryNumber}/> In my controller class
InputStream inputStream=accessoryPicturesLOB.getPicture().getBinaryStream();
byte[] theBytes = new byte[inputStream.available()];
inputStream.read(theBytes);
response.setContentType("image/jpg");
response.getOutputStream().write(theBytes);But the problem is, *if i right click on the image and select save picture as option i get a error saying "The system cannot find the specified file "*
Can you please tell me what is wrong in my approach/code
Is there any better approach to display image that is store in Blob variable ?
Please help on this.
Thanks in advance.

You need at least to set the filename in the content disposition header.

Tab canvas does not put the items in their specified positions

Hi all,
I have created a form with a tab canvas with three tab pages, each page has it's own text items.
I saved this form without any problems.
When i open this form again, i found that, some of the items in the first tab page are not put in their positions in this page, although the x position and y position is still correct in the property pallette.
i overcome this by moving these items with the mouse to any direction and returning it back, but the problem comes after saving and trying to open the form again.
Not : this occures only in the first tab page, i tried to swap the second tab page(page7) with the first tab page (page6), now the problem occures with page7(which became the first after swap) .
Please help

Yes, the items are in a frame.
Both automatically and locked for the frame upate layout property causes the problem.
I want to tell that the form in run time is ok, but in the forms builder the text items are not in their specified positions.
Then when changing any property for the items even if it was not related to the item position, the item is then displayed in the correct position.

How to adjust R/W rules to display images inline?

Hi all,
out of the box, when I insert an image in a paragraph (DITA 1.2) then FrameMaker 12 uses the "below line" display setting. I need to display it inline, at the insertion point.
When I adjust the settings of the anchored frame then the inline setting is lost when saving the XML file. So evidently I need to adjust the R/W rules.
I tried to add a corresponding inline rule but had no success so far, does anybody know what needs to be done? It seems like a quite common requirement to display images inline.
Robert

Robert, Scott,
     I just did a non-DITA test of the r/w rule:
         element "Image" {
      is fm graphic element;
      attribute "placement" {
        is fm property position;
        value "inline" is fm property value inline;
        value "break" is fm property value bottom;
     My test document had two Image elements, one positioned at the insertion point, one at the bottom of the column. In both cases, the placement attribute was set correctly when I saved the document as XML and interpreted correctly when I opened the XML document.
    Robert, does your EDD define the placement attribute? If so (and you want to keep it), you need to add the subrule
        is fm attribute;
to the attribute subrule. However, since setting the attribute in the FM document does not affect the anchored frame position, so I recommend deleting the attribute from the EDD. The r/w rule I suggest assumes the attribute is XML-only.
    Before you make that change, though, I wonder if the value "inline" appears in italics in the Structure View. Italics indicates the default value for an attribute that has not been set. That would explain why you see the value in the Structure View but not in the attribute editor.

Css style sheet will not display images

If i hardcode my style into the Login header.
Change my body to reflect my html changes for div tags
the login displays the way I want.
If I remove my style and link to an uploaded style doing the following.
<link rel="stylesheet" href="#WORKSPACE_IMAGES#SAMPLE2A.css" type="text/css">
the images do not display. Everything else from the style sheet works
just the images do not.
I am doing the following to display the images
#header {background: url("#WORKSPACE_IMAGES#testheader.png") no-repeat; width: 743px; height: 123px; position: relative;}
is "#WORKSPACE_IMAGES#testheader.png" correct way to display images when doing css
Howard

#WORKSPACE_IMAGES# is not substituted in files, such as css at runtime, only in the page template (and other places in apex). The best way that I've found is to define the bulk of your classes in a .css, and only the image attributes in the page template header. Or, you can just store everything on the filesystem in Apache and use relative paths.

Display Images stored on filesystem

Hello,
I have stored photos (JPEG images) in my OS filesystem and trying to create album to view them using BFILE datatype and stored procedure. I would like to diaply one photo on each page withlinks to next and previous photos. I was able to make this working but have still following issues.
- It only shows image for first row. For other rows, the strored procedure doesn't even run.
- The 'Layout and pagination' for report displays more rows on each page, even if I specify "Number of Rows" as 1.
Could you help me fix these issues? Also, if you have better way to do it, I am willing to try.
Thanks.

Is it possible not to download/display images ?

When the connection is low, it would be convenient not to download images from the websites. Is there a way to do this ?

Look at the following information. If this seems to be what you want, then you can un-check an option:
*'''''Load images automatically:''' Firefox displays images in web pages by default. Uncheck this option to disable images in web pages. If you enable loading images automatically, the Exceptions... button lets you select sites from which images will not automatically load. '''The Exceptions... button lets you specify websites that you wish to load (or not load) regardless of the setting of this preference. In the exceptions list, enter the site from which you want to allow or block images and click Allow to allow images, or click Block to block the images. '''''
*the above is from this article --> https://support.mozilla.org/en-US/kb/Options%20window%20-%20Content%20panel

I want resize the image and set position after retrieving from oracle datab

How can I display image on web page after retrieving it from oracle database. Display is not problem but resize that image and position is very dificult .Please send me Guideline about blob object todisplay and resize it in web pages

I tried to do the suggetion made by you but I was not able to solve the issue. I think I am close to it and with your help I should be able to resolve it. Let me explain you the brief about this issue.
1. Another group uses Oracle Apex to load the images in to the database.
2. I am fetching this data fron Oracle and displays in to Webpage using PHP.
This is so far I tried. Please bear with me if I am doing anything wrong.
1.I created program.php which calls the <IMG> as suggested by you.Snippet of the code is
<div><img src="/oracle/image_story.php" alt="Image Stories" width="900" height="500" /></div>
2. In the image_story.php, I used the following code.
<?php
$query = "SELECT *
          FROM IMAGE_STORY WHERE image_id = 50";
if ($result = run_oracle($query, 'select')) { // Run the query.
     $num_results = count($result);
     if ($num_results > 0) {
     foreach($result as $row){
          $img = $row['DOCUMT']->load();
          header("Content-type: image/pjpeg");
          echo $img;
          //echo '<div><img src="'.$img.'" alt="Image Stories" width="900" height="500" /></div>';
?>
When I run the program.php,Image is not displayed and it is showing as "X". To troubleshoot the issue,I run the image_story.php and echo $img is giving me the weird character like,
"ÿØÿàJFIFddÿìDuckyPÿîAdobedÀÿÛ„
I used PL/SQL developer as a client to access the BLOB field from the database and in the HTML view, it is giving me the same output.
Select * from image_story a where a.image_id = 50
I am not sure the issue is with the MIME-TYPE,ENCODING or I am missing something here. I tried lot of Content-Type.
Please guide me.

Displaying images that are accessed through URL

Hi,
I have trouble displaying images that are accessed through URLs in my report.
If I call the URL directly in the Browser the Image can be opened without problems.
The images can be accessed with an anonymous access.
When I deploy the report or in the Preview of Visual Studio I get the following message:
[rsWarningFetchingExternalImages] Images with external URL references will not display if the report is published to a report server without an UnattendedExecutionAccount or the target image(s) are not enabled for anonymous access.
In Layout View of Visual Studio the image is showen correctly.
The Images are stored on a Solaris maschine with WebSphere 6.0 as WebServer.
Any ideas?
Thank you.

Hello again!
Anyone that can help me figure out how to implement this in an MVC layout, I feel stuck.
I post a little program that open and display an image file so that you better can understand what I whant to do.
ShowImage
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.File;
import javax.swing.filechooser.*;
public class ShowImage extends JFrame{
     //Variables
     JFileChooser fc = new JFileChooser();
     PicturePanel pp = null;
     ShowImage () {
          super("Show"); //Title
          //Create the GUI
          JPanel top = new JPanel();
          add(top, BorderLayout.NORTH);
          JButton openBtn = new JButton("Open");
          top.add(openBtn);
          openBtn.addActionListener(new Listner());
          //Settings for the GUI
          setDefaultCloseOperation(EXIT_ON_CLOSE);
          pack();
          setVisible(true);
     class Listner implements ActionListener {
          public void actionPerformed(ActionEvent ave) {
               int answer = fc.showOpenDialog(ShowImage.this);
               if (answer == JFileChooser.APPROVE_OPTION){
                    File f = fc.getSelectedFile();
                    //Check
                    System.out.println(f);
                    System.out.println(pp);
                    if (pp != null)
                         remove(pp); //Clean so that we can open another image
                    //Check
                    System.out.println(pp);
                    //Set the PicturePanel
                    pp = new PicturePanel(f.getAbsolutePath());
                    //Check
                    System.out.println(pp);
                    //Add PicturePanel to frame
                    add(pp, BorderLayout.CENTER);
                    validate();
                    pack();
                    repaint();
     //Main
     public static void main(String[] args) {
          new ShowImage();
}PicturePanel
//Import Java library
import javax.swing.*;
import java.awt.*;
public class PicturePanel extends JPanel {
     //Variables
     private ImageIcon picture;
     //Method to get information of the selected file
     PicturePanel (String fileName) {
          picture = new ImageIcon (fileName); //Get the filename
          int w = picture.getIconWidth(); //Get the image with
          int h = picture.getIconHeight(); //Get the image height
          //Set preferable size for the image (Use the properties for the selected image)
          setPreferredSize(new Dimension(w, h));
          setMinimumSize(new Dimension(w, h));
          setMaximumSize(new Dimension(w, h));
     //Method to draw the selected image
     protected void paintComponent(Graphics g) {
          super.paintComponent(g); //We invoke super in order to: Paint the background, do custom painting.
          g.drawImage(picture.getImage(), 0, 0, this); //Draw the image at its natural state
}//The endEdited by: onslow77 on Dec 16, 2009 7:30 PM
