Displaying the image stored in Blob column

Hi all,
I'm trying to print the report with an image. I've stored the image in a Blob column and the format of the image is Jpg.
I'm using the Reports 10g(10.1.2.0.2). When I'm trying to print the report, I'm getting an error Rep-62203. I want to know whether there are any settings which i need to set to display the image item. I mean to say that are there any registry settings.
Regards,
Alok Dubey

How to display the content of a BLOB column in a ADF/BC pages ?

How to display the content of a BLOB column in a ADF/BC pages ?
There is some image in database table blog column. And we want to display image on the screeen.
There is some example about upload and dowload blog columns.
(steve not yet document example page etc...)
But We want to display blog picture in a image component...
is there any basic way to do it ?
Thanks a lot...

Ali,
You could just download the sample app... but... here is the servlet code from the demo (look at it just for technique - you'll obviously have to change it for your needs)...

Displaying images stored in blob columns

I've seen discussions on how to upload and download blob columns but I want to store a blob in the database and be able to display the blob (which is a jpg) as I would any other <img> on my web page. Instead of having to store the jpg on a file system somewhere, and use the data in the database to formulate a link to the image on the file share, I want to pull it right out of the blob. Does someone have a sample of how to do this? Can I do this?
Thanks

Laurence,
If you uploaded the image via the Application Builder, you can use an image tag like so:
<img src="#WORKSPACE_IMAGES#my_image.jpg" />If you followed the upload/download how to, you should be able to reference an image like this:
<img src="download_my_file?p_file=1232897645" />Where 1232897645 is the unique ID of the uploaded image. To make referencing images easier, you could write a version of the download_my_file procedure that takes in the name of the image as a parameter.

Image stored in BLOB column crashes report's engine

Hi,
I have a report where I display logos stored in a BLOB column on the DB.
The report is generated as RTF.
When images have sizes of 624x168 or 423x324 everything is OK. One image, 1221x224, is crashig the report with a dr. Watson error.
Any idea why?
The size of the "bad" image file is 38K, and the "good" ones are about 300K.

I altered student table to store photoes of students. For this I added STIMG as blob, MIMETYPE,FILENAME,IMAGE_LAST_UPDATE COLUMNS to studentadmitted table. Image stored and displayed in report very nicely. With the following query

Images are displayed in column but they have different sizes.Stick to declarative BLOB images as above. They can be resized in reports using CSS. Add a style sheet in the page Inline CSS property:
td[headers="IMAGE"] img {
display: block;
width: 75px;
border: 1px solid #999;
padding: 6px;
background: #f6f6f6;
}where the <tt>IMAGE</tt> value in the attribute selector is the table header ID of the image column. Setting only one dimension (in this case the width) scales the image with the correct aspect ratio. (The border, padding and background properties are just eye candy...)
However, if the original images are large then scaling them in the browser this way is a huge waste of bandwidth and produces poorer quality images than creating proper scaled down versions using image tools. Downloading megapixel images and then reducing them to thumbnail size results in pointlessly pushing millions of bytes that will never be seen.
For improved performance and image quality, and where you require image-specific scaling the best approach is to use the database ORDImage object to produce thumbnail and preview versions automatically. Note that this is not possible in Oracle XE as Multimedia is not included

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.

Problem displaying PDF stored in BLOB column

Hello everyone.
I've been trying to follow this tutorial http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::p11_question_id:232814159006 on displaying PDFs stored in BLOB columns. This is being performed on Apex 4.2, with my DB running 11g. I've got my procedure, which I'll post below:
create or replace procedure "PDF" (p_id IN gvo_documents.doc_id%type)
is
    l_lob    blob;
    l_amt    number default 30;
    l_off   number default 1;
    l_raw   raw(4096);
begin
    select contents into l_lob
        from gvo_documents
         where doc_id = p_id;
-- make sure to change this for your type!
    owa_util.mime_header( 'application/pdf' );
    begin
        loop
          dbms_lob.read( l_lob, l_amt, l_off, l_raw );
          htp.prn( utl_raw.cast_to_varchar2( l_raw ) );
          l_off := l_off+l_amt;
          l_amt := 4096;
    end loop;
        exception
           when no_data_found then
              NULL;
        end;
end;
I am trying to run this through a PL/SQL dynamic region and while I don't receive any error's, the content displayed is a huge mess of garbled text and odd characters. I've tried to run this procedure on numerous other document types, including word files and jpeg images, all with the necessary changes in my procedure, and regardless of what I use, I still get a large mess of strange characters. Does anyone have any information or ideas about why this is happening?

If I understand correctly, your requirements needs to be broken down into two problems:
1) click link that pops up a window displaying a new APEX page
2) an APEX page the displays the document, not downloads it.
I haven't done #1 (yet).
However, you may be able to generate a URL that points to the new page as part of the SELECT statement for the Report.
This has a related question, but no answer yet:
open pdf in popup browser window
The key is target="_blank" for the anchor tag.
To generate the URL, you should use the APEX_UTIL.prepare_URL() function.
If that doesn't work, a Dynamic Action that does some magical JavaScript stuff may be needed.
For #2, I lost the URL that showed how to display a PDF as part of a "form" page.
From what I remember:
Start with a blank page with one blank HTML region (all the Items go in the HTML region)
Add an Item for the PK/Doc_ID
part I forgot Create a Data Manipulation Process
- Automated Row Fetch
- On Load - After Header
- (stuff for your table/view)
part I forgot Create an (I believe) "File Browser" item type. For Settings:
- Storage Type "BLOB column specified in Item Source" (and place the column name of the BLOB there)
- MIME Type Column: (column name) -- since you have multiple types, this is a MUST HAVE
- Filename Column: (column name) -- I highly recommend you have this.
- Content Disposition == INLINE <-- this is the kicker
Also, you will need a Browser Plugin for each of the MIME Types (otherwise, the browser may try to 'download' the file)
Browsers can handle Image types internally. Adobe's plugin can handle PDFs. I don't know about Word/Excel.
Again, I don't remember the exact details, but that should cover most of it.

Display images stored in BLOB in html pages via JSP

Hello,
My images are stored in BLOB column of other base than portal.
in JSP i have to display them in html pages.
anybody have already did the same thing ?

teggvb6,
I believe you should be able to get it to work by doing the grants to the user specified in the DAD (i.e. the user that is logging into Oracle) rather than PUBLIC (someone else may correct me on this?).
If you're concerned that the procedure could be called by others then I guess you could do some sanity checking within the procedure, for example checking v('APP_USER') or maybe v('SESSION') or perhaps do something clear with the REFERER http header? I haven't thought this through yet but I'm pretty sure you should be able to tie it down a bit more.

Download/Display the image files stored at KM location: J2EE application

Hi All
Please let me know how to download/Display the image files stored at KM location on portal using J2EE application. Thanks.
Best Regards
P M

You can use a servlet to deliver the image data to the <img tag, which allows you to get the data from something other than a file on the server (e.g. store the image data as a session attribute with a generated attribute key, the key being given in the serlvet's query string).

How to insert a pdf or jpeg image into a blob column of a table

How to insert a pdf or jpeg image into a blob column of a table

Hi,
Try This
Loading an image into a BLOB column and displaying it via OAS
The steps are as follows:
Step 1.
Create a table to store the blobs:
create table blobs
( id varchar2(255),
blob_col blob
Step 2.
Create a logical directory in the database to the physical file system:
create or replace directory MY_FILES as 'c:\images';
Step 3.
Create a procedure to load the blobs from the file system using the logical
directory. The gif "aria.gif" must exist in c:\images.
create or replace procedure insert_img as
f_lob bfile;
b_lob blob;
begin
insert into blobs values ( 'MyGif', empty_blob() )
return blob_col into b_lob;
f_lob := bfilename( 'MY_FILES', 'aria.gif' );
dbms_lob.fileopen(f_lob, dbms_lob.file_readonly);
dbms_lob.loadfromfile( b_lob, f_lob, dbms_lob.getlength(f_lob) );
dbms_lob.fileclose(f_lob);
commit;
end;
Step 4.
Create a procedure that is called via Oracle Application Server to display the
image.
create or replace procedure get_img as
vblob blob;
buffer raw(32000);
buffer_size integer := 32000;
offset integer := 1;
length number;
begin
owa_util.mime_header('image/gif');
select blob_col into vblob from blobs where id = 'MyGif';
length := dbms_lob.getlength(vblob);
while offset < length loop
dbms_lob.read(vblob, buffer_size, offset, buffer);
htp.prn(utl_raw.cast_to_varchar2(buffer));
offset := offset + buffer_size;
end loop;
exception
when others then
htp.p(sqlerrm);
end;
Step 5.
Use the PL/SQL cartridge to call the get_img procedure
OR
Create that procedure as a function and invoke it within your PL/SQL code to
place the images appropriately on your HTML page via the PL/SQL toolkit.
from a html form
1. Create an HTML form where the image field will be <input type="file">. You also
need the file MIME type .
2. Create a procedure receiving the form parameters. The file field will be a Varchar2
parameter, because you receive the image path not the image itself.
3. Insert the image file into table using "Create directory NAME as IMAGE_PATH" and
then use "Insert into TABLE (consecutive, BLOB_OBJECT, MIME_OBJECT) values (sequence.nextval,
EMPTY_BLOB(), 'GIF' or 'JPEG') returning BLOB_OBJECT, consecutive into variable_blob,
variable_consecutive.
4. Load the file into table using:
dbms_lob.loadfromfile(variable_blob, variable_file_name, dbms_lob.getlength(variable_file_name));
dbms_lob.fileclose(variable_file_name);
commit.

Display a PDF from a BLOB Column on a page.

Hi Folks.
I have PDFs stored in BLOB columns in the database.
Is there a way to display these to the APEX user on the page at runtime?
Any pointers appreciated.
Meantime I'm going to experiment.
Cheers
Dogfighter.

I suppose this depends really on what you want.
You have at least two choices.
1) Allow the user to download the pdf and then they get the option to save it or open it in a new window
2) You can also get them to open it. You can open it in a new window by adding "_blank"
in the target.
The sample application has procedures download_my_file and custom_image_display which will show you how to achieve this.
The only other way you could possibly do it is open it as a plugin. Thats way beyond my knowledge, but I'm sure someone else will chip in.

Image from database blob column

Hi all,
Is it possible to show the image stored in data base column(blob type) in image component without using servlet.? ( I mean in a declarative way.)
I saw lot of samples which all using servlet. I needed to know whether it is possible to show image in more simple way.
Thanks,
Gijith.

No, using a servlet is the way to go.

Loading images stored as BLOBs in MySQL

Hello,
For various reasons, I would prefer to store binary data like images and videos as BLOBs within a MySQL database and have Flash retrieve that content directly from the database as opposed to getting it from a URL on a fileserver. So, I have written a PHP script that Flash calls which does a database query and returns the bitmap data from the BLOB. I have verified that the image data is being sent from the database through the PHP, but Flash either doesn't display the image or gives me an error saying that it is an unknown type.
Here is the AS3:
var imageLdr:Loader = new Loader();
//imageLdr.dataFormat = "binary";
imageLdr.load(new URLRequest("http://www.XXXXXXXXXX.com/cgi/getToken.php"));
imageLdr.contentLoaderInfo.addEventListener(Event.COMPLETE, loadImage, false, 0, true);
function loadImage(evt:Event):void {
    trace("Now in loadImage...");
    tokenHolder.addChild(imageLdr);
    addChild(tokenHolder);
    trace("loadImage complete...");
Here is the getToken.php file code:
<?php
$hostname = "dbhost";
$username = "username";
$password = "pword";
mysql_connect($hostname, $username, $password) or die ("<html><script language='JavaScript'>alert('Unable to connect to database'),history.go(-1)</script></html>");
mysql_select_db($username);
$query = "SELECT content FROM media WHERE id=2";
$result = mysql_query($query);
$data = mysql_result($result, 0);
$im = imagecreatefromstring($data);
if ($im !== false) {
    header('Content-Type: image/png');
    imagepng($im);
    imagedestroy($im);
else {
    echo 'An error occurred.';
?>
Is there a way to get Loader() to accept bitmap image data that is retrieved from a BLOB in a database? Should I try to get PHP to mimic the response from an HTTP server or is there another way to load bitmap data stored as a BLOB into a display object?
Thanks!

Hey
Thanks for sharing your problem and how you get data as image in php. It gave me clue about my problem about getting blob info from database to as3 and displat it as image. So what i did is:
In this fuction;
function loadImage(evt:Event):void {
    trace("Now in loadImage...");
     tokenHolder.addChild(imageLdr);
    addChild(tokenHolder);
     trace("loadImage complete...");
I changed it to:
public function loadImage(evt:Event):void {
                trace("Now in loadImage...");
                img= evt.currentTarget.content as Bitmap;
                trace("loadImage complete...");
img is a Bitmap variable and I used Image component and stated its source as imgg ( source={img} )
I hope you can solve your problem
Have a good day...

How to get the image stored in archieve link as an attachment in work item.

Hi All,
through transaction OAWD we are storing scanned images.
Once this transaction is executed a workitem appears in the inbox of the initiator with the scanned invoice as attachment.
When the user executes the work item FV60 screen is displayed where the user enters the data based on the scanned invoice attachment.
After the user Parks the document the custom workflow triggers and a workitem appears in the inbox of an approver.
Our requirement is that the scanned image should also appear as the attachment.
Can you please suggest how to get the image stored in archieve link as an attachment in work item.
Regards
Shraddha

Hi Martin,
with every parked document a scanned image is linked.
I need to create a link under objects and attachments in the work item, such that when the user clicks that link the image is displayed.
At present the following functionality is available.
The BO used is FIPP
Objects and attachments:
parkeddocument:AK0108500001252008.(via FIPP binding with WIOBJECT_ID)
On clicking the link below objects and attachments: the parked document AK0108500001252008 opens in display mode.
Now we want to have 2 links:
parkeddocument:AK0108500001252008.
image.
When we click on the link image then the scanned invoice linked to the document should get opened.
I am able to get the image id of the the image through SAP_WAPI_GET__OBJECTS,
