Displaying BLOB jpg images

I have saved gifs and large jpgs into database BLOB columns in a table, using JDeveloper's interMedia imageControl.
The smaller gifs display peachy in an Image column using reports 6i in the live previewer. The larger jpgs all come back with a REP-1818 Unable to read data in image format.
The column elasticity is fixed/fixed.
a) Does Reports 6i handle 1MB+ jpgs?
b) If elasticity is fixed/fixed... does it crop? Or shrink? Or what?
c) Is there something that I am doing wrong that I can change?
TIA

Alayan - If you're using XE, that shoud be the first thing you tell us. There is a separate forum for that product.
But as long as you're here, a couple points: you reference the "display" procedure in the img tag without qualifying it with an owner. How is the Embeded PL/SQL Gateway supposed to know what "display" is (unless you created a public synonym)? Next, in XE you need to explicitly enable access to procedures that are invoked this way. See the XE forum for discussion about that technique and read the doc here: http://download-uk.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25309/adm_wrkspc.htm#BEJCGJFJ.

Display BLOB/CLOB image data in OBIEE 11g

Dear Gurus,
I want to display employee profile picture in dashboard, the image data was saved as blob/clob image.
How to configure and display it in obiee?
Regards
JOE

Hi
Thanks for your quick response.
actually im not using EBS, im just using publisher with OBIEE 11g.
if explain step by step what you wrote first replay-
Let i have a table with one BLOB column.
1) first load blob data to my table
2) create data model from oracle publisher.
3) change the xdm file with above tagline , my xdm file is in below link-
C:\mw_bi_home\instances\instance1\bifoundation\OracleBIPresentationServicesComponent\coreapplication_obips1\catalog\SampleAppLite\root\shared\zia%2exdm
i don't know is that right step? because if i re-open the xdm file after change by your given tagline its shows error.
I will grateful to you please give me a little explanation which file i can put the following tagline.
_<fo:instream-foreign-object content-type="image/jpg"><xsl:value-of select=".//IMAGE_ELEMENT"/></fo:instream-foreign-object>_
Thanks again and waiting your feedback -

Display blob field image in Oracle Express

Hi,
I upgraded the apex in my Oracle express edition to 3.2 and tried to display image in blob field following the step in the Apex tutorial,
but the error '*The requested operation is not allowed* ' prompt.
I save the image file in a table with fields mime1,picture1=> blob field.
I created a problem as follow:
CREATE OR REPLACE PROCEDURE download_my_file(p_hotel_id in number) AS
v_mime VARCHAR2(48);
v_length NUMBER;
v_file_name VARCHAR2(2000);
Lob_loc BLOB;
BEGIN
--execute immediate
--'SELECT MIME_TYPE'||to_char(p_picture)||', picture'||to_char(p_picture)||', '||to_char(p_picture)||',DBMS_LOB.GETLENGTH(blob_content) '||
--'INTO v_mime,lob_loc,v_file_name,v_length FROM hotels_pic '||
--'WHERE hotel_id = '||to_char(p_hotel_id);
select mime_type1,picture1,'test/picture1',DBMS_LOB.GETLENGTH(picture1)
INTO v_mime,lob_loc,v_file_name,v_length
from hotels_pic where hotel_id=1;
-- 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="'||replace(replace(substr(v_file_name,instr(v_file_name,'/')+1),chr(10),null),chr(13),null)|| '"');
-- close the headers
owa_util.http_header_close;
-- download the BLOB
wpg_docload.download_file( Lob_loc );
end download_my_file;
GRANT EXECUTE ON download_my_file TO apex_PUBLIC_user;
GRANT EXECUTE ON download_my_file TO public;
I tried display the image by using <img src="#OWNER#.download_my_file?p_hotel_id=1" height=60 width=40 /img>
But the image don't display...
if I type http://127.0.0.1:8080/apex/HOTEL.download_my_file?p_hotel_id=1 to display the picture , the error " Forbidden,The requested operation is not allowed" prompt.
Am I miss out anything? Anyone can help?
Thanks
Vincent

Hi,
I use a slightly difference code to display images: [http://apex.oracle.com/pls/otn/f?p=267:11]
It is possible that your GRANT command needs to be for PUBLIC instead of public - some things are case-sensitive.
Also, have you checked in SQL Workshop, Object Browser, Procedures to see if your procedure is valid?

I save two copies of an image, one jpg, one tiff. LR will not display the jpg or let it be available, only the tiff. When I try to put another copy of the jpg into the folder LR says the jpg is already there.e

I converted an rgb image into a grayscale image and saved two copies, one jpg, one tiff, into my chosen folder.
I tried to import both into LR, which only showed the tiff in the import dialogue. After import LR only shows the tiff in the folder but when I try to insert the jpg into the folder using Explorer LR reports that the jpg is already in folder.
How can I get LR to display this jpg image?

Hi,
I have an example here that is intended to demonstrate the difference between Positioned and Flowed subforms: http://assure.ly/i8pSdy.
This shows how you can use a slider to change the dimensions of the image object.
I have extended this to an example with buttons to scale the image: http://assure.ly/i8ZI5Y
This may not be fine enough for your purposes, but it may give you some ideas.
Good luck,

Display blob with forms6i

Hi,
i thought it would be easy ti find how to do it nut from searching this site and with google i couldn;t find the answer for that.
i have blobs in a table (jpg,doc,pdf ...) .
how can i display those blobs (jpg,doc,pdf ...) in forms6i ?
can you give me step by step how to .
thanks allot for any help
Zvika

You can display a jpg image in an image item. But you cannot directly show pdf in Forms (like you do with a plugin in a browser). You can put the file on the file system and then open it with a HOST command or the DDE package.
This is an example from the online help:
** Start MS Excel with spreadsheet emp.xls loaded

AppID := DDE.App_Begin('c:\excel\excel.exe emp.xls',

Error displaying a jpg file loaded into a table with blob field

This may not be the correct forum for this question, but if it isn't could someone direct me to the correct one.
I have created a table with a blob field in which I have loaded a jpg image.

Just a little more information. When I enter owa_util.mime_header('image/jpeg') I can't display the file. It just shows up with a red x for the file.
When I enter owa_util.mime_header('image/jpg') it displays the file, but in the format
¿¿¿¿JFIF¿¿-Intel(R) JPEG Library, version [2.0.16.48]¿¿C
This is the way I would expect it to look if I opened it with Notepad, or an application that doesn't recognize jpg files. Can anyone tell me what I am doing wrong?? Thanks.

I have done exactly that in one of my applications.
I have extracted the image from the database as a byte array, and displayed it using a servlet.
Here is the method in the servlet which does the displaying:
(since I'm writing one byte at a time, it's probably not terribly efficient but it works)
     private void sendImage(byte[] bytes, HttpServletRequest request, HttpServletResponse response) throws IOException {
          ServletOutputStream sout = response.getOutputStream();
          for(int n = 0; n < bytes.length; n++) {
               sout.write(bytes[n]);
          sout.flush();
          sout.close();
     }Then in my JSP, I use this:
<img src="/path-to-servlet/image.jpg"/>
The name of the image to display is in the URL as well as the path to the servlet. The servlet will therefore need to extract the image name from the url and call the database.

Displaying .jpg images stored in the database

I created a table and a form to store .jpg images then display the .jpg files in a dynamic page.
I can insert the images and display the dynamic page but selecting the HREF link will not dispaly the .jpg file.

You'll need to provide a full URL link to the image ("http://mywebserver/file/images_personnel/28.jpg"), not just a relative path. Remember, the email client that is used to view the email content knows nothing of the internals of your web server - it can only follow a complete URL to get images and other resources.

Displaying BLOB image by using ADF Faces

Hi all,
I digged the forum but couldn't find any satisfied answer about displaying BLOB images by using ADF Faces.
I have insterted POJO object to Oracle database but couldn't find any way to display blob (in java byte [] ) data in POJO.
I have read the POJO object from database which contains two field; one of them is id field and other is BLOB data which holds GIF or JPG image and I want to display this image another page which contains also other fields / records ...
thanks for your answers
regards...

This thread at Sun : http://forum.java.sun.com/thread.jspa?threadID=513804&messageID=2445090
talks about two options for creating a graphicImage jsf tag. (img tag)
1. Make the img tag url refer to a servlet (instead of a static image file)
2. Embed the image into the tag as inline base64 encoded data.
2a. Use an <Object> tag with inline data.
1. Looks a bit complex for a simple problem.
2 and 2a don't work with some browsers.
- And I've not yet figured out how to hook into the ADF Faces table-rendering logic to get it to add my image column. My table binds to a collection DataControl, [which in turn retrieves from a findAllItems call on a session facade, which uses my domain model, and wraps up access to a TopLink pesistence layer]. The framework just ignores my byte[] attribute when creating the jsf table from the DataControl. All string, int etc. attributes get represented correctly in the jsf table output.

Problem with displaying BLOB images on JSP page using a servlet

hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
               BLOB blob=null;
          rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
          while (rset.next())
               blob=((OracleResultSet)rset).getBLOB(2);
          response.reset();
          response.setContentType("image/jpeg");
          response.addHeader("Content-Disposition","filename=42.jpeg");
                ServletOutputStream ostr=response.getOutputStream();
               InputStream istr=blob.getBinaryStream(1L);
                int size=blob.getBufferSize();
          int len=-1;
                byte[] buff = new byte[size];
                     while ((len=istr.read( buff ))!=-1 ) {
               ostr.write(buff,0,len);
         response.flushBuffer();
         ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.

I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : )

Display BLOB (image) column in (interactive) report

Hi,
I have a field called "picture" in my table "details" which is of type BLOB. i also have a field for "MIMETYPE" and "filename"
i additionally have a "name" and "description" columns which i need to display along with the picture as columns in a report (preferably interactive).
i have also modified the BLOB display format as per
http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/apex/r31/apex31nf/apex31blob.htm
what i am missing is the correct query. if possible, i would like to control the size of the picture rendered within the report like say 40*50.
I have also referred to the thread
APEX 3.1 Display BLOB Image
But i don't know how to place the
dbms_lob.getlength("BLOB_CONTENT") as "BLOB_CONTENT"
in my query.
The above also makes the report column as of type "number". is this expected?
Any help would be much appreciated.
Regards,
Ramakrishnan

You haven't actually said what the problem is?

border: 1px solid #999;

}where the <tt>PICTURE</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, scaling large images 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. For improved performance and image quality, and where you require image-specific scaling you can use the database ORDImage object to produce thumbnail and preview versions automatically, as described in this blog post.

How can I display a JPG Date Taken stamp on images?

I have several digital JPG images taken that I would like to pull EXIF data from to display a timestamp on the photo. I know many old cameras used to do this natively, but my iPhone does not imprint the date and time on the images. I want to pull the data from the JPG so it will display the correct info on the image for when the picture was taken. Any help is appreciated. I own Adobe Web Premium CS5.
Thanks, Bryan

If the EXIF metadata is in the jpeg you can do what you want using a photoshop script retrieve the date and time in matadata and add a text layer containing a timestamp. Here is an example where more then just the timestamp was stamped onto an image. http://www.mouseprints.net/old/dpr/StampExif.jsx

JPG images not displayed correctly in Bridge and Photoshop

I am using CS4 under OSX 10.4.11 on a PowerMac G5 Quad. Images which have been captured as JPG are displayed fine by Preview, but when opened in Bridge, Camera Raw or Photoshop. the colours are all "washed out". The attached screen capture should give an idea of the difference, with the upper being Camera Raw (image settings) and the lower being Preview. My monitor has been calibrated and I'm using sRGB IEC61966-2.1 colour space in Camera Raw and Photoshop. what could be causing this?

I've done some more experimentation. After opening the image in Photoshop without adjustment, then Save As JPEG with embedded color profile, Preview displays the new image the same as Photoshop. Save As JPEG without embedded color profile, and Preview displays this copy just like the original. It seems that Photoshop is making different (incorrect) assumptions about what color space to use when there is no embedded color profile. Shouldn't it assume sRGB like everything else? Or is its interpretation of sRGB incorrect? How can I fix this?

JPG images not displayed correctly in Bridge and Photoshop (Mac OS)

(Note: I have copied the content of this query from the Creative Suites forum where I originally opened it.)
I am using CS4 under OSX 10.4.11 on a PowerMac G5 Quad with 23" Apple cinema display. Images which have been captured as JPG are displayed fine by Preview, but when opened in Bridge, Camera Raw or Photoshop. the colours are all "washed out". The attached screen capture should give an idea of the difference, with the upper being Camera Raw (image settings) and the lower being Preview. My monitor has been calibrated and I'm using sRGB IEC61966-2.1 colour space in Camera Raw and Photoshop. The colours displayed by Preview are pretty close to "real life". I find it virtually impossible to adjust the colours in Photoshop to get back to anything similar.

…If there is someone out there who has experience of obtaining decent colour management in CS4 on a Power PC, I would really like to know how you achieved it.
That would be yours truly, and I hasten to reply because I may have some insights that can help you too.
Just get it it out of the way, here's my setup:
Photoshop 11.0.2 ("CS4"); VersionCue disabled and uninstalled.—2.5 GHz Power Mac (PPC) G5-Quad; 16GB RAM; mutant, flashed 550MHz nVidia GeForce 7800GTX 1,700MHz 512MB VRAM; ATTO ExpressPCI UL5D LP SCSI card; Mac OS X Tiger 10.4.11 and Leopard 10.5.8 boot drives; Spotblight, Dashboard and Time Machine permanently disabled; dual 22" CRT monitors; USB wireless 'n' available but connected to the Internet via wired Ethernet; 1 FW flatbed scanner; 2 SCSI scanners (one tabloid-size transparency scanner and a film scanner); various internal & external HDs; FW Epson 2200 and Ethernet Samsung ML-2850ND printers; 2 X Back-UPS RS 1500 XS units.
I can unambiguously and in good faith represent to you that my color management, from capture to print, is as spot-on as anyone with any kind of setup can hope to achieve. Unequivocally and without qualifications.
Now, first things first: Forget about trying to synchronize color management across the point applications lumped together only by Adobe marketing fiat into a variety of meaningless "creative suites". Concentrate on Photoshop. Do not try to use Bridge to synchronize anything.
The "suites" are a totally artificial construct created by Adobe bean counters and marketing types. The point applications (i.e. the individual programs clumsily bundled together, e.g. Photoshop, Illustrator, InDesign, etc.) are developed independently by separate engineering teams that are not only not in the same building, but in different cities, different states of the American Union, and even in different countries. They have very little communication among them, if any, as evidenced by repeated posts in these forums by Photoshop engineering staff urging us, the end users, to let the other teams know in their own forums that a given problem exists and is actually affecting our work.
Enough said about the cause of the problem. The end result is that Color Management is at very, very different levels of progress and sophistication in each individual point application, with only Photoshop fully entitled to be considered state of the art.
Secondly, a disclaimer: I have been hanging on to my CRT monitors and take care of them as Jascha Heifetz used to take care of his Stradivarius. I don't know what I will do if I manage to outlive the usefulness and accuracy of my CRTs (unlikely at this point). I have despaired in futile efforts to bring the luminosity of any LCD monitor down to where I would feel comfortable calibrating and profiling it. I believe my monitors are the foundation of my color management efforts.
Especially if you have one of the extreme wide-gamut LCD or LED monitors, you'll face an uphill battle.
Be careful to avoid any version 4 icc profiles, whether canned or generated by your calibration software. Stick to version2 icc profiles. Ask the manufacturer of your calibration software/hardware if in doubt.
Here are some not-too-recent, but thoroughly representative screen shots of the calibration results I obtain with my monitors, which I calibrate and profile often and regularly (I validate the calibration at least several times per month).
In a nutshell, my color management practices and settings mirror those described by Bruce Fraser, Jeff Schewe, Andrew Rodney and Gary Ballard's site. I have learned from all of them.
My working color space is ProPhoto RGB. I choose to work with PSD and PSB files. As a long-time, rabid JPEG hater, I only rarely deal with JPEGs, using them sporadically to illustrate a point in this forum or elsewhere in the web. My main output consists of prints.
I only deal with tagged image files (files with an embedded color profile) and often recommend beating up with a baseball bat any moron that hands you an untagged file—figuratively of course, but I find the expression gets my point across unambiguously.
Following is a screen shot of some of my pertinent settings:
Note that I have never bought into the "suite" concept myself. I do have and routinely use Adobe Illustrator 10.x, InDesign 2.x and Acrobat Professional 8.x, but they are all older, independent versions of each point application, licensed at different times.
Be further advised, that the answer to many problems offered by Adobe engineers often is not to install VersionCue, or uninstall it, or at least disable it.
Also, as outlined at the beginning of this post, concentrate on Photoshop, not on synchronizing applications that can't really communicate with each other, despite the claims of Adobe marketing hacks to the contrary.
One big caveat, do not fall into this trap:

You either want to learn, or you don't. You either want to solve your problems, or you don't.
When you start arguing instead of studying, questioning advice instead of following it and detecting where you went wrong, you're on the right track to nowhere. That attitude will get you there fast. Remember you are the one with the problem, and only you can acquire the discipline to learn how to solve it.
Go ahead and ask me anything that is not clear, just don't argue with me please, and don't tell me why you think Fraser, Rodney, Ballard and I are wrong. You see, I am not experiencing any problem that needs fixing. I have an interest in helping you, but not in hearing about your speculations, theories or conclusions.
Good luck.
