Display image file - BLOB on Report

Hello there,
Has anyone knew how to display an image file (BLOB) on Report using Application Express?
You prompt reply would be appreciated.

Once htmldb.oracle.com is available again, you may have a look in my demo application:
http://htmldb.oracle.com/pls/otn/f?p=31517:1
In the tab section II, you will find an image display example and the corresponding
procedure.

Can anyone help me plz?
Thnx in advance.

Hello,
It is very difficult for us to "guess" what images you can read and what others you cannot.
Maybe you could provide more information on images that are not displayed ?
What is their native format ?

Displaying Encrypted Image File in Crystal Report

Post Author: Riaz Afridi
CA Forum: General
Hi Folk,
I have a problem to display an encrypted file in crystal report with transparent background.
I have a column varbinary(Max) in SQL Server Database which stores image bytes. I have decrypted this column before displaying in crystal report. The report display the image but with a black background instead of transparent.
Is there an answer to this ...
Thanks

I believe jpg and bmp images are supported

Display image data in a report

Hello.
I have a table with a BLOB column that stores images.
I want to run a report and display the images.
Say my blob column is named IMAGE_DATA.
I want my report definition to be simply SELECT IMAGE_DATA FROM T; and I want the page to display the images in one neat column, one underneath another.
I have managed to build a report that in the IMAGE_DATA column shows a hyperlink called "download" and if I click on it, it takes me to a page displaying the image file. (I use dbms_lob.getlength("IMAGE_DATA") for the report and then "DOWNLOAD:T:IMAGE_DATA:ID" in the number/date format for the report attributes)
But that's not what I want.
I want the report to list not the hyperlinks all saying "download" in the IMAGE_DATA column that, if clicked on, would take me to the images. I want the report to display the actual images in the report itself.
Is it possible? If so, what's the magic sause recipie?
Thank You
Boris

Hello Boris,
You can use something like
decode(nvl(dbms_lob.getlength(p.product_image),0),0,null,'<img src="'||apex_util.get_blob_file_src('P8_PRODUCT_IMAGE',p.product_id)||'" height="75" width="75" />') img
in your select statement.
See the documentation and/or [this blog post|http://dgielis.blogspot.com/2008/07/show-blob-of-other-table-in-apex-form.html].

Displaying multi-page BLOB on Reports

Hi to all,
I have experience with Forms but unfortunatelly not much with Reports.
I've been succesful at querying and displaying the content of a BLOB column that stores .TIFF images.
I've made the same steps described on the post: Display images from a BLOB
"Field.Source: my blob's column name
Column.File format: image "
I've set the vertical and horizontal elasticity properties of the field and the container repeating frame to Expand.
However, the report only displays the first .tiff image, although the same BLOB column contains multiple images
Do I need to change more properties in the repating frame or in reports in general to achieve this?
Or do I have to iterate this images either programatically?
Either way, how can I do this?
Any help would be appreciated.
Best regards,
Jorge

What it sounds like you are trying to do is have a detail
page listing detail records about documents followed by pages of
those document images.
Try designing two reports, one for the detail pages. Then
design a report to display the just the images. You should
pre-determine if the images exist.
Then combine the two reports onto a new report. This parent
report should reference common value(s) that are the same for all
details.
So first design a query that provides all your information,
including image file names with path and an indicator if the file
exists and all the detail for the detail report and perhaps an
identifier to connect the line item to the image.

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

Displaying images in a HTMLDB Report

I have a procedure(pdt_image_display) that accepts a imageid and returns a blob content and mime_type value in the select into clause.
The procedure is called through a SQL Report using the following image src tag
SELECT <col1>,
'<img src="#OWNER#.pdt_image_display?p_image_id=' || nvl(<imageidcolumn>,0) || '" height="50" width="50" />' img
from <Image Table >
The report when run couldnt display the images..
Can anyone help me to display an image in a htmldb report
Thankyou

I have done this many times. Eventually you miss the right syntax or you didn't grant execute to your procedure to public. Here is one of my examples you may use to compare with yours:
SELECT NULL download, related_documents, subject,
       || get_category_type (category_type)
       || category_type,
       || get_subcategory_type (subcategory_type)
       || subcategory_type,
       get_subcategory_description (subcategory_type) description,
       '<im g src="#OWNER#.marketing_image_display?p_image_id='
       || NVL (ID, 0)
       || '" height="'
       || NVL (display_height, 100)
       || '" width="'
       || NVL (display_width, 70)
       || '" />' img,
       SUBSTR (get_subcategory_type (subcategory_type), -1, 1) series_type,
       sort_flag
FROM marketing_images
WHERE NVL (TO_CHAR (category_type), '%') LIKE
          CASE
             WHEN TO_CHAR (:p4_category_type) = '-1'
                THEN '%'
             ELSE :p4_category_type
          END
   AND NVL (TO_CHAR (subcategory_type), '%') LIKE
          CASE
             WHEN TO_CHAR (:p4_subcategory_type) = '-1'
                THEN '%'
             ELSE :p4_subcategory_type

Display image from BLOB field (png image)

Hello,
On my database i have a function which return BLOB (png image from a webservice)..
Is there some tutorial or sample code how to display a image froma blob field in oracle reports?
thank you

You can create a view and base your report on that view. The view would be something like:
create or replace view my_view as
select my_blob_function() image
from ...In your Report it would just be:
select image
from my_viewNow, I'm not sure if Reports supports png format, though.
There are many examples to be found, e.g.

Displaying image in BLOB via pl/sql cartridge

Hi gurus ,
I have a oracle web site. I am dynamically putting links in the page using pl/sql cartridge and procedures. I have loaded all my pictures for the catalog in the BLOB columns. Can anyone help me or direct me how to display these images using plsql cartridge dynamically from BLOB columns instead of from image files ???
null

Originally posted by Dan Mullen:
I'm not familiar with the PL/SQL cartridge.
Since this is the interMedia forum my suggestion would be to store the image data in an ORDImage column and use the interMedia WebAgent to retrieve the data.
The interMedia WebAgent can be used with "naked" blobs but you'll need to code your own pl/sql routines (the code wizard won't do it for you).
The code wizard does generate procedures for OrdImages but due to some reasons the GET_XX procedures don't work and give the error "ORA-04043 Object Get_Image does not Exist <br><br>"

Efficiency of decoding and displaying image files?

BRIEF SUMMARY
My question is this: can Flash Player download JPG and GIF
files from a server and rapidly open/decode them, ready for
display, efficiently and
entirely 'in memory'?
Would Flex be a good choice of language for developing a RIA
that needs to continually download lots of JPG and GIF images
on-the-fly from the server and render them on the screen? I *don't*
want my application to thrash the hard disc.
BACKGROUND
I am designing a 'rich' web app, and I'm investigating
whether Flex is the right tool for the job.
Although Flash's animation features are an obvious selling
point for implementing my user interface, I also need to do some
server-side rendering. What I want to do is perhaps a little
unorthodox: I will be generating lots of GIF and JPG files on the
fly and these will be streamed to the client (along with other
application data, e.g. in XML format) to update different parts of
the on-screen document. In need this to happen very quickly (in
some cases, creating the effect of animation).
It happens that JPGs and 16-colour GIFs will be, by far, the
most efficient formats for streaming the images, because of the
nature of the application. I could of course send the images in
some proprietary format, geared for my application, but presumably
decoding the images would be slow as I would have to implement this
myself in ActionScript, and so I would be limited by the speed of
Flex 'bytecode'. (I realise Flash is a lot more optimised than it
once was, but I am hoping to see a gain from using image formats
that Flash natively understands!)
Naturally the internet bandwidth should (in principle) be the
bottleneck. However, assuming I can get my image files to the
client on time, want I want to know is:
how efficient is Flash at loading such files?
Bearing in mind that I'm not just displaying the occasional
image -- I will be doing this continuously. Most of the images
won't be huge, but there will be several separate images per
second.
The image files will be a mixture of normal colour JPGs and
4-bit colour GIFs (LZW-compressed). I know that Flash natively
supports these formats, but depending on how Adobe have implemented
their LZW/Huffman decoding and so on, and how much overhead there
is in opening/processing downloaded image files before they are
ready to 'blit' to the screen, I imagine this could be pretty fast
or pretty slow!
If my client only has a modest PC, I don't want the JPG/GIF
decoding alone to be thrashing his CPU (or indeed the disc) before
I've even got started on 'Flashy' vector stuff.
I'm new to Flash, so are there any 'gotchas' I need to know
about?
E.g. Would it be fair to assume Flash Player will do the
decoding of the downloaded image entirely 'in memory' without
trying to do anything clever like caching the file to disc, or
calling any libraries which might slow down the whole process? It
would be no good at all if the images were first written to the
client's hard disc before being ready to display, for example.
Further, if I'm doing something a little out-of-the-ordinary,
and there is no 'guarantee' that images will be loaded quickly,
what I'm doing might be a bad idea if a later version of Flash
Player may (for example) suddenly start doing some disc access in
the process of opening a newly downloaded image. So, while I could
just 'try it and see', what I really need is some assurance that
what I'm doing is sensible and is likely to carry on working in
future.
Finally, I imagine JPG/GIF decoding could be something that
would vary from platform to platform (e.g. for the sake of
argument, Flash Player for Windows could use a highly-optimised
library, but other versions could be very inefficient).
This could be the 'make or break' of my application, so all
advice is welcome! :) Thanks in advance.

You need a servlet/jsf component to render the image in the response.

Apex 4.0 display image item :BLOB column returned by SQL statement

Hello
I'm creating an display image item in apex 4.0. The source is a BLOB column returned by SQL statement.
When I'm issuing an sql statement like this:
   select lado.blob_content
   from   large_documents      lado
   ,        large_doc_headers    ladh
   where lado.ladh_nr = ladh.nr
   more criteriait works fine.
When I create a function inside a package with the same query (in a cursor)
function get_image(some parameters in) return blob
Following in apex by:
select get_image(some parameters) from dualI get a
ORA-06502: PL/SQL: numeric or value error: character string buffer too smallAnybody any idea why this does not work?
Regards Erik

Hi Eric,
the environment assumes varchar2-output by default, which will be limited to 32767 characters and may have problems with binary formats. You could define a blob-variable to select the value into.
DECLARE
l_blob BLOB;
BEGIN
SELECT get_image(some parameters)
    INTO l_blob
    FROM dual;
END;
/If you expect the BLOB-Content to be text (you should consider CLOB then), you may use UTL_RAW.CAST_TO_VARCHAR2 to convert the content. If your object is larger than the maximum varchar2 size, or you want to convert BLOB to CLOB, you might be interested in some converter like described here: {message:id=559749}
Hope this is what you were searching for.

Display image file from outside web

Hi.
My application is in c:\projects and I need to display images from d:\Photo.
Can anybody tell me how to do that?
BR
Soren

You could always make a servlet which loads the image from that directory.
<img src="/servlet/imageServlet?image=myImage.jpg">
Have the ImageServlet load the file from disk, and send it out via the ouputstream.
Apart from that no. Web applications can only access directories under their context. Accessing anywhere else would be a security issue.
