Display Image on report through Field Definitions Only File.

Hi all,
I have a report where I work with Field Definitions Only files (ttx).
These files are mapped to classes in code behind (csharp).
In code behind I make lists of these classes. Each list is set as the datasource of a subreport.
This works great!
My new goal:
Now I tried adding a picture to my report.
In the TTX file I added a BLOB field.
In the code-behind class I added a System.Drawing.Image.
My actual problem:
The class gets filled with the image, but the image is NOT displayed on the report
Does anyone know why this is happening?
How can I fix this? (should I use another Type in my class for the picture?) (should I format the picture in the report? ....)
Kind regards,
Wim

Hi AG,
Thanks for your response.
This is my TTX field:
Signature BLOB
I can't see the image in the report because I create the image in code-behind.
I think the problem doesn't occur in CrystalReports but in the conversion from my StrokeCollection (I use an InkCanvas [WPF] to capture a signature) to a ByteArray.
I am already one step closer to the solution. You can't just assign an object of type Image to the BLOB field of the report but it has to be a Byte-Array.
The problem I am facing now is that the picture is black after a conversion. (I see this when I export to disk and open the file in MSPaint).
The good thing is that CR shows me a black image so I guess CR is doing its job!
Kind regards,
Wim

Error when trying to display a Webi report through the Folder iView

Hi all
I am getting the following error when Im trying to display a Webi report through the SAP Portal. We have installed the SAP Integration Kit and are able to see the content of the Infoview. However when we click on a Webi report, we receive the following error:
Could not get page number. (Error: RWI 00223) (Error: INF)
Have anyone else encountered this problem? Please assist! Any help will be rewarded.
(We are running XI Rel 2).

Hi Jim Ji
The report can be displayed from the java infoview, no doubt, so the report itself works.
But the report cannot be seen from the "SAP Infoview" (:/businessobjects/enterprise115/sap) which is the infoview, I reference from the Folder iView (through the system in the SAP portal). And since the SAP Portal Integration Kit seems very old - the Folder iView was created 12-08-2004 by Ingo Hilgefort - there might be an old version of the jar-files somewhere in the installation.
I guess I should check the version of the jar-files in WEB-INF/lib of our web application (Tomcat) folder, and see if they have been overwritten by the SAP Portal Integration Installation or are an older version of the files in Program FilesBusiness Objectscommon3.5javalib? And also check if somewhere in the .../sap installation there are some old jar-files?
Kind regards,
Martin Søgaard

No data found when display image in report

Hi,
I have a table with a blob field in it which I use to store some image (gif),
I tried to display the image in report but follow the guideline in http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21674/advnc_blob.htm#BCGBCHBD
but when I run the report, error
"report error:
ORA-01403: no data found"
prompt, I do not have MIME,FILENAME column in the table, so I define only
IMAGE,Table Name,Column containing BLOB,Primary Key Column 1 and Primary Key Column 2 in the report column.
Anyone has also this problem?
Thanks
Pek

Hi,
I found that the problem is there when I select the option
"Use Generic Column Names (parse query at runtime only)" in the report.
Is this a bug?

Display Image in Report

Hi,
I want to display image link in one of the columns in report.
ex: if i click that image it should go to google maps.
I stored the image in /res/s_protal/image.jpg and also in oc4j.
I know to fmap to show it only once.
but i want to reflect it in all the rows of a column.
Things i tried:
Stored in the same machine took the ip addres and prot and given as below it was working.
But if i move it to other machines then it getting failed so again i want to update the machine ip.
http://225.225.225.225:9704/analytics/res/s_proact/images/images.jpg
Is there any possible way to give some common syntax so that the corresponding machine ip will be pointed once the
report moved to different machines.
Thanks,
satheesh

Hi Santeesh,
I just saw your post and I thought I'd ask you with my query:
I want to add some pop-up info on some of the data when the user hover on it. have you
got a clue what do I need to do for that?
Cheers,

Displaying image in report

I'm new to CF Report Builder and having trouble determining
how to get a dynamic image to display in the detail band. The query
for the report correctly returns the image file name, but the
following expression doesn't display the image although the path is
correct.
IIf(query.image NEQ "", DE("../images/smProds/" &
query.image), DE("None"))
When I run the report, I get just .. in the space where the
image should display if one is available and the text "None" if the
field is empty. I found a tutorial on Report Builder that suggested
using similar code, but it didn't provide an actual example. Using
their code produced the same lack of results.
I've tried various versions of this with no success yet. Am I
missing something about how to include an image in the report? A
static image in the report uses the same basic path information. Of
course that image name and path aren't being generated from an
expression, it is just an inserted image and it shows up in the
header and footer bands as expected.
Thanks for any guidance.

Thanks for the response. Sadly yes, the path is correct. I've
tried both the relative path and the full path (e.g.
../images/theimage.jpg and
http://mysite.com/images/theimage.jpg)
. Putting either address into a browser will return the correct
image if I'm in the right location.
So, I can get this expression: IIf(query.image NEQ "",
DE("../images/smProds/" & query.image), DE("None")) to display
the correct path, but what I really need is the image located at
that spot to display in the report. What is happening is that
report builder is returning the string, but not the image. When I
looked at the tutorial it implied that the image would be displayed
rather than the string.
Is there something in report builder that determines whether
the actual image is displayed? A property setting that I'm missing?
Or maybe the expression iteself is wrong i.e. it is doing exactly
what it should (display the string) and a different expression
format is required to get the image iteself. For example, flagging
some text as a hyperlink to the image? Not sure how you would pass
the image name value in that case.
Appreciate your suggestions.

Displaying images in dynamic text fields

Hi, I am having some difficulty getting my images to display
in a dynamic text field. The images are linked from a txt file with
the <img src=""> tag however they are not showing up in the
text area. The rest of the html are rendering fine except the image
tag. My example online is here:
www.supernaturalmedia.com.
Here is the code I used in Flash:
var style_sheet = new TextField.StyleSheet();
var css_url = "global.css";
style_sheet.load(css_url);
news.StyleSheet = style_sheet;
loadVariables("projects_news.txt", this.news);
My css styles also isn't loadin so i temporarily am using
html styles for formatting. I'd like to get the css to work as
well.
My movie is published as Flash Player 6, AS 2.0.
I'd appreciate any helpful advice.
Thanks,
Stanton

1. don't assign the stylesheet property of your textfield
until loading of global.css is complete. ie, use the onLoad handler
for stylesheets.
2. you have movieclip images that are linked for export and
you're using their linkage id in src property of the img
tag?

Error: "file not found" when try to display image on report

Dear All
I have a problem when running my report.
My Table emp_info Stores all data about employees in addition to the employee image path.
I made a report that display employee information including its photo.
I run my report passing the parameter p_emp_id to display the desired emploree information.
I made a field on the report to display the employee image
and i set its property READ FROM FILE = YES and FILE FORMAT=IMAGE
But the following error occurs
"File '\\iai3\iaigc\ALL\emp_images\51.JPG' not found. "
I'm sure that the path is correct
But i do not know why the report stops and can not read the image path.
My platform is:
Oracle application server installed on linux
and oracle report builder installed on widows for development

Dear aweiden
thanks for replaying
I belive you are right . I think the problem is in the path.
But there is something that i did not mentioned to you. I work on two different servers.
1- "iai2" : Linux server which contains oracle application server.
2- "iai3" Windows 2003 server which contained oracle database 10g and the folder "aigc\ALL\emp_images" which contains Employees images
I think that the problem is that Linux server can not understand the path "\\iai3\iaigc\ALL\emp_images\51.JPG".
Do you have any idea how the path should be changed so that Linux can recognizes it.
Thanks in advance

Display image in report page but just a link if file is not an image

Hello,
I've been working on displaying an image in a report page but need to add some logic.
I would like to be able to call the image using a Region Source of type SQL instead of the HTML Expression. The reason for this is because I need to use logic to determine if the file is an image or not and to determine wether to show a thumbnail or just a link. I did find a "GET_BLOB_FILE_SRC" Function on the internet that suggests that I could do this but I need some help in making it work in my application.
Here it is as a Region Source of type SQL:
SELECT ID,
NAME,
CASE WHEN NVL(dbms_lob.getlength(document),0) = 0
THEN NULL
ELSE CASE WHEN attach_mimetype like 'image%'
THEN '<img
src="'||apex_util.get_blob_file_src('P4_DOCUMENT',id)||'" />'
ELSE '<a
href="'||apex_util.get_blob_file_src('P4_DOCUMENT',id)||'">Download</a>'
end
END new_img
FROM TEST_WITH_BLOB
If anyone can help me with this that would be appreciated.
Thanks
LEH

John,
The problem is that I do not know how to use the "GET_BLOB_FILE_SRC Function". I never got it to work but the HTML Expression did work for me. If you know how the GET_BLOB_FILE_SRC Function works then that would be helpful. I don't think it would be helpful if I posted my example on apex.oracle.com. But here is the information I have on the GET_BLOB_FILE_SRC Function.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
GET_BLOB_FILE_SRC Function
As an alternative to using the built-in methods of providing a download link, you can use the APEX_UTIL.GET_BLOB_FILE_SRC function. One advantage of this approach, is the ability to more specifically format the display of the image (with height and width tags). Please note that this approach is only valid if called from a valid Oracle Application Express session. Also, this method requires that the parameters that describe the BLOB to be listed as the format of a valid item within the application. That item is then referenced by the function.
See Also:
"About BLOB Support in Forms and Reports" in Oracle Application Express Application Builder User's Guide
Syntax
FUNCTION GET_BLOB_FILE_SRC (
    p_item_name           IN VARCHAR2 DEFAULT NULL,
    p_v1                  IN VARCHAR2 DEFAULT NULL,
    p_v2                  IN VARCHAR2 DEFAULT NULL,
    p_content_disposition IN VARCHAR2 DEFAULT NULL)
    RETURN VARCHAR2
Parameters
Table 1-28 describes the parameters available in GET_BLOB_FILE_SRC function.
Table 1-28 GET_BLOB_FILE_SRC Parameters
Parameter Description
p_item_name
Name of valid application page ITEM that with type FILE that contains the source type of DB column.
p_v1
Value of primary key column 1.
p_v2
Value of primary key column 2.
p_content_disposition
Specify inline or attachment, all other values ignored
Example
As a PLSQL Function Body:
RETURN '<img src="'||APEX_UTIL.GET_BLOB_FILE_SRC('P2_ATTACHMENT',:P2_EMPNO)||'" />';
As a Region Source of type SQL:
SELECT ID,
       NAME,
       CASE WHEN NVL(dbms_lob.getlength(document),0) = 0
            THEN NULL
            ELSE CASE WHEN attach_mimetype like 'image%'
                      THEN '<img
src="'||apex_util.get_blob_file_src('P4_DOCUMENT',id)||'" />'
                      ELSE '<a
href="'||apex_util.get_blob_file_src('P4_DOCUMENT',id)||'">Download</a>'
                      end
        END new_img
   FROM TEST_WITH_BLOB
The previous example illustrates how to display the BLOB within the report, if it can be displayed, and provide a download link, if it cannot be displayed.Thanks

Displaying images in report builder

aoa to all!
Dear gurus, i want to develop such type of report in report builder 6i.
empno employee name emp photo
1 abc (here i want to show photo)
i have build such report but the problem is when any employee who has no photo, i want to display default photo. i m displaying photo using the below steps
1. create a formula column of type char which returns the path of emp photo like this ' return 'd:\photo\' || :empno || '.gif';
2.create a field in layout and set the read from file property set to yes and format to image.
my requirement is when a new employee record is entered into table emp but his photo is not currently in the directory then i want to display a logo.
hope my question is clear. thanks in advance. plz reply a.s.a.p

Asim
in your select statement you can check if the employee has not its picture or picture field is null then return logo. for this you have to assign some default value to the field Like 'N' is default value for picture field so when there is not picture or field is null then 'N' will be its default value and you can check in your query like
SELECT DECODE(pict, 'N',Logo,pict) FROM emp

Display images in report

Hi,
we have stored students images in a directory i.e 'D:\pics'. now I want to display the images of student on a reports dynamically, the name of image files are same as student id.
I do not want to store them in data base tables.
Any soltuion??

If the report gives an error and doesn't run if the image doesn't exists in the image folder,
use the exception handling to verify that if the image doesn't be in the image folder then display the default image.
For example, if your query looks like this:
SELECT deptno deptno,
       dname dname,
       'DEPT' || deptno || '.jpg' dept_image
FROM dept
ORDER BY deptnoand DEPT_IMAGE (pseudo)column has properties "Read from file = Yes" and "File Format = Image",
remove these properties from DEPT_IMAGE and create (in DEPT group)
CF_DEPT_IMAGE formula column ("Read from file = Yes" and "File Format = Image"):
FUNCTION cf_dept_imageFormula RETURN CHAR IS
l_filename text_io.file_type;
BEGIN
l_filename := text_io.fopen ('.\images_directory\' || :dept_image, 'r');
text_io.fclose (l_filename);
RETURN :dept_image;
EXCEPTION
-- the report photo doesn't exist
WHEN OTHERS THEN
BEGIN
    l_filename := text_io.fopen ('.\images_directory\default_image.jpg', 'r');
    text_io.fclose (l_filename);
    RETURN 'default_image.jpg';
EXCEPTION
    -- the report photo 'default_image.jpg' doesn't exist
    WHEN OTHERS THEN RETURN NULL;
END;
END;In Layout Model, source for F_DEPT_IMAGE field is CF_DEPT_IMAGE (not DEPT_IMAGE).

I'm curious to see if there is a solution for this problem, because if there isn't only requesting PDF or MHTML formats make sense.
Is there a new setting replacing the html-image-base-uri property? Is there another viable way embedding Publisher reports in our ADF application?

This is being seen when running the report from within our application. The report itself has been created and designed from within CR Designer v10. The actual report that the images are on is a on a subreport. The reason for this is that the main report needs to show a different number of images, either 1, 2, 4 or 6, depending on how many images are linked to the data in the database.
We are using the CR SDK designed for use with Borland Delphi 7.

WHERE NAME = :p6_filename;
DELETE wwv_flow_files
WHERE NAME = :p6_filename;
:p6_filename := NULL;
END IF;
END;
after that i want to show the columns and the image in a report. so i created a report in a new region quite similar to the example in the obe
it works fine, the image columns is shown as "[datatype]"
whenever i change the format of the image colum of the report to
DOWNLOAD:MY_SAL201:GRAFIK:GRAFIKDID::::::inline:Herunterladen
(just one example, IMAGE:... does not work as well)
no more rows are shown but the error h3. "ORA-06502: PL/SQL: numerischer oder Wertefehler: Fehler beim Konvertieren von Zeichen zu Zahl"

i'm to silly to work with images :-ß
i did copy ur example to another app on http://apex.oracle.com/pls/otn/. fine->igames are shown.
on a new page in my local app, i did exactly the same (create a table, procedure, ect) it does not work.
rows are shown inthe report, but no images, instead the icon for a broken/missing image is displayed.
i tried to debug using firebug:
in the sample app on otn, when i point the mnouse over the procedure call, the image appears in a tool-tip
in my app, the code is quite simmilar, nothing happens. no icon
>
<img width="50" height="50" src="WMF_GL_INTMAN001.DISPLAY_IMAGE?inID=1"/>
>

maybe this is important: i'm using apex 3.2.0.00.27 on db version 11g
