Display Image from Procedure Call

Hi,
i am using Apex 4.02 with LDAP authentication
I am using al PL/SQL Region that calls a function.
this function looks like this
procedure get_apps
is
begin
--Hole alle Apps
htp.prn('<table><tr>');
for rec in (select name from kast_apps) loop
htp.prn('<td>'||rec.name||'</td>');
htp.p('<img src="#OWNER#.my_image_display?p_image_id=1" />');
end loop;
htp.prn('</tr></table>');
end;
the procedure my_image_display is from denes kubicek
http://apex.oracle.com/pls/otn/f?p=31517
i did GRANT EXECUTE ON my_image_display TO PUBLIC;
but my image is jut a red "X"
the adress is
https://xxxxx:4443/apex/f?p=110:1:2739030448962509:::::#OWNER#.my_image_display?p_image_id=1
what wrong??

You could try out the HTLML Importer to make a TextFlow. The scope of the HTML handled is fairly limited.
var textFlow:TextFlow = TextFilter.importToFlow(source,TextFilter.HTML_FORMAT)
The Flex 3.2 SDK doesn't know anything about TLF TextFlow's or markup. Don't you just want to set the TextField.htmlText property? I'm not sure how that's exposed in Flex - that would be a better question for a Flex forum.
Hope that helps,

Display Images from HTMLDB_APPLICATION_FILES Table?

How do I display images from the HTMLDB_APPLICATION_FILES Table?
Are the contents full available potentially for display? Or only after I have written them to another display?
Please advise what I need to do or what corrections below is required:
The calling procedure is a item in a SELECT statement as part of a report query:
<P>
<(img src="#OWNER#.download_HAF_file?p_file= ' || nvl(ID,0) || ' height="50" width="50" )>, HAFimg<P>
The Procedure is a adaptation of the Chapter 8 Exercise of the 2 day developer guide:
CREATE OR REPLACE PROCEDURE "DOWNLOAD_HAF_FILE" (p_file IN NUMBER) AS
     v_mime VARCHAR2(48);
     v_length NUMBER;
     v_file_name VARCHAR2(2000);
     Lob_loc BLOB;
BEGIN
     SELECT MIME_TYPE, BLOB_CONTENT, NAME, DBMS_LOB.GETLENGTH(BLOB_CONTENT)
     INTO v_mime, lob_loc, v_file_name, v_length
     FROM HTMLDB_APPLICATION_FILES
     WHERE ID = p_file;
     -- set up HTTP header
     -- use an NVL around the mime type and
     -- if it is a null set it to application/octect
     -- application/octect may launch a download window from windows
     owa_util.mime_header( NVL(v_mime,'application/octet'), FALSE );
     -- set the size so the browser knows how much to download
     htp.p('Content-length: ' || v_length);
     -- the filename will be used by the browser if the users does a save as
     htp.p('Content-Disposition: attachment; filename="'||SUBSTR(v_file_name,INSTR(v_file_name,'/')+1)|| '"');
     -- close the headers
     owa_util.http_header_close;
     -- download the BLOB
     wpg_docload.download_file( Lob_loc );
END Download_HAF_File;

I believe you put HTML "pre" tags around your quote (with square brackets, I can't type them here because they'll be escaped).
If the example below looks formatted then using "pre" works, if not...then ignore me ;)
begin
select
    count(*)
into
    v_count
from big_table;
end;

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 ?

My iphone 4s suddenly displays images from Yahoo, Google, and Flickr at low resolution. The camera on my phone works fine, but any web related photo content is now pixelated and low res, what's the deal?

My iphone 4s suddenly displays images from Yahoo, Google, and Flickr at a low resolution. I have IOS 7.0.4. My phone camera works fine, but any web based photo content from Safari, Yahoo images, Google images, and Flickr all come in pixelated and low res. What's the deal?

It happened to me but later I figured out that cellular signal was not that great and so the Internet was very slow. It took me about 2 minutes to get the full resolution picuture on either of the app you've described. Try to get faster internet either by wifi or good signal and then check.

Display images from a SQL database

I want to display images from a SQL database. The images are in a table under a specific column and are stored as a link to the image. How would I display the images from the column in LabVIEW?
I'm using LabVIEW 2013 version 13 and SQL Server 2012
Paul Power
I have not lost my mind, it's backed up on a disk somewhere

Hi PauldePaor,
I hope you are well.
Once you have pulled the data from the database into LabVIEW in a string form (or path), you can simply use the Read BMP File (Or jpg, png depending on the file type) VI.

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

Using flash to display images from sql server or file system

hello,
what methods and parameters of the urlloader class we have to use to display images in a flash player if possible..
also movie should update everytime a new image is added to a database or file
the images can either be in a file system or in a sql database (if possible)
does flash comes with an object of this type or we have to create it.
regards,

i responded to your duplicate message 4 days ago:
is it possible to insert and retrieve images from sql server using actionscript.
you'll need server-side script to query your database and you can use the flash urlloader class to call your script.
also is it possible to create a flash scrolling gallery based on images stored in a database and everytime an image is added it is displayed in the gallery.
load the data using the urlloader class and then load the images. periodically query the database for new images if there's no direct way for flash to know a new image was added.

Hello,
You can't directly add picture into "Hyperlink or Picture" column because this column takes URL value and image is binary etc. You can first upload that picture into picture library (create new picture or document library) then add that image link
into that column.
To add/edit "Hyperlink or Picture" column, SP provided special class called "SPFieldUrl". Wheer you need to pass URL and description as parameter.
Refer this link for you ref:

Displaying image from database table.

Hi All,
   I am very new to Web Dynpro ABAP.
I am developing an application to display an image in "Image" UI Element.
For this I have one table consisting of fields image id, image data and image name. here image id is primary key field.
Now i want to display an image from that table in "Image" UI Element. For this i am using "Filedown load" UI element.
But by using filedownload ui element i can diaplay image in another new page.
But my requirement is to display image in the same web page without creating a new one.
(I want to display the image in "Image" UI element without storing that image in MIME objects.)
Can anyone help me.
Thanks in Advance!
Regards,
Sreelakshmi.

What you describe is completely possible. Since you have the image data (XSTRING) in the context you have everything you need. You don't need to store the content into the MIME Repository, but you do need to get it somewhere where it has an externally accessible URL. Remember you need to supply image UI element with a URL. This URL is processed on the client side by the web browser. Therefore just giving it a path to the context won't work as that isn't externally accessible.
I would suggest instead that you place the image content into the ICM cache temporarily. This lets you basically generate a temporary URL for the image that can be used by the Image UI element.
Here is some example code that pushes images into the ICM Cache:
****Create the cached response object that we will insert our content into
DATA: cached_response TYPE REF TO if_http_response.
CREATE OBJECT cached_response
    TYPE
      cl_http_response
    EXPORTING
      add_c_msg        = 1.
   try. " ignore, if compression can not be switched on
      call method cached_response->set_compression
        exporting
          options = cached_response->co_compress_based_on_mime_type
        exceptions
          others = 1.
    catch cx_root.
endtry.
****set the data and the headers
DATA: l_app_type TYPE string.
DATA: l_xstring TYPE xstring.
      cached_response->set_data( me->gx_content ).
      l_app_type = me->gx_mimetype
cached_response->set_header_field( name = if_http_header_fields=>content_type
                                     value = l_app_type ).
****Set the Response Status
cached_response->set_status( code = 200 reason = 'OK' ).
****Set the Cache Timeout - 60 seconds - we only need this in the cache
****long enough to build the page and allow the Image on the Client to request it.
cached_response->server_cache_expire_rel( expires_rel = I_CACHE_TIMEOUT ).
****Create a unique URL for the object
DATA: guid TYPE guid_32.
CALL FUNCTION 'GUID_CREATE'
    IMPORTING
      ev_guid_32 = guid.
CONCATENATE i_path '/' guid '.' i_format INTO r_url.
****Cache the URL
cl_http_server=>server_cache_upload( url      = r_url
                                       response = cached_response ).

Display image from database with jspSmart

Hi
I have successfully uploaded and saved images into oracle(8.1.5) table DATA_TYPE(dtid number, iconname varchar2(30), icon blob). When I try to display a specific icon in my browser, I get "javax.servlet.ServletException: General error" at:
PreparedStatement pstmt = myConnection.prepareStatement(mySQL);

I think that it may help you get image from database. I used two jsp page. First one is getphoto.jsp that makes as table based in sql statment and invoke the getimage.jsp this last returns images based on
the getphoto.jsp PhotoId.

Display Images from Database

Hi all,
I require to display images stored in database along with textual description of it on a JSP.
The image file should not be stored intermediately on file system (i.e w/o using img HTML tag)
It is a typical shopping cart appln. where images are fetched from database and the associated description is displayed along side.
Please note that it is the case of Mixed content types(text and binary data).
Thanks and Regards

Like "Breakfast" said, you can do this with a servlet that retrieves your images from a database....
if you create a servlet to do this, you would have a generic servlet which retrieves a picture from a database based upon a key which could be a picture name or number.
Lets say the file is out there in the database as a BLOB or Binary Image... you could have this kind of code in the doPost(HttpRequest req, HttpResponse res) or doService(HttpRequest req, HttpResponse res) method.
The table holding the image has at least two columns one called IMAGE which holds the binary image and the other called FILENAME. If the connection to the DB is already open, you do something like this.
String fileToGet = (String)req.getParameter("FILENAME");
rs = conn.createStatement().executeQuery("select from IMAGE_TABLE where FILENAME='" + fileToGet + "'");
if(rs.next())
InputStream in = rs.getBinaryStream("IMAGE");
res.setContentType("image/jpg"); // or whatever type of file it is.
ServletOutputStream sout = res.getOutputStream();
int c;
while((c = in.read()) != -1)
sout.write(c);
in.close();
sout.close();
This should write your image to the response output of the servlet.
Now, where you want your image, you put.
<img src="/servlet/ImageServlet?FILENAME="thefileIwant">
This should do what you want... Use your favorite pipe copy method to get the input stream to the output stream. If you are worried about overhead and scaling like "breakfast" said (it CAN be a problem in high access sites), then you can add an image caching scheme and get really complex.... But this is a rough idea on what to do.
Hope this helps.
