• image not displayed programmtically stored in the blob column

  Hello
  
  I modified the student table to store photos of students. To do this, I added STIMG as BLOB, FILENAME, MIMETYPE, IMAGE_LAST_UPDATE COLUMNS in the studentadmitted table. Image stored and displayed in the report very well. With the following query
  
  Select "ROWID",.
  "ST_ID."
  "FIRST NAME",
  'NAME',
  "FFIRST_NAME,"
  "FLAST_NAME,"
  "COURSE_ID."
  'SESSION_ID '.
  "CONTACT #" "CONTACT_H", nvl ((STIMG) dbms_lob.getlength, 0) IMAGE.
  of ' #OWNER # '. " STUDENTADMITTED ".
  Images are displayed in the column, but they have different sizes.
  
  To control this, I changed the query like this
  
  Select "ROWID",.
  "ST_ID."
  "FIRST NAME",
  'NAME',
  "FFIRST_NAME,"
  "FLAST_NAME,"
  "COURSE_ID."

• Stored in the BLOB column display PDF problem

  Hello everyone.
  
  I tried to follow this tutorial http://asktom.oracle.com/pls/asktom/f?p=100:11:0:p11_question_id:232814159006 on the display of PDF files stored in BLOB columns. This is done on Apex 4.2, with my DB 11 g running. I have my procedure, which I will 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 region dynamic PL/SQL, and even if I don't get any error, the content displayed is a huge mess of truncated text and strange characters. I tried to run this procedure on many other types of documents, including word and jpeg image files, all with the necessary changes in my inside, and regardless of what I use, I always get a big mess of strange characters. Does anyone have information or ideas why this is happening?

  If I understand correctly, your needs must be broken down into two problems:
  1) click the link that opens a window showing a new APEX page
  (2) an APEX page displays the document, download it not.

  I did not (yet) #1.
  However, you can generate a URL that points to the new page in the select for the report.

  It's a related issue, but no response yet:
  Open the pdf file in the browser window

  The key is to target = "_blank" to the anchor tag.
  To generate the URL, you must use the APEX_UTIL.prepare_URL () function.

  If this does not work, a dynamic Action that makes magical things of JavaScript may be necessary.

  # 2, I lost the URL that showed how to display a PDF file in a page "form.
  From what I remember:
  Start with a blank page with a pristine area of HTML (all items will in the HTML area)
  Add an element to the PK/annual
  part I forgot Create a Data Manipulation process
  -Automated row Fetch
  -By loading - after the header
  -(stuff for your table/view)
  part I forgot Create a (I think) "File browser" item type. For the parameters:
  -Storage of Type "BLOB column specified in the Source element" (and put the name of the BLOB column)
  -MIME Type column: (column name) - since there are several types, this is a MUST HAVE
  -Filename column: (column name) - I highly recommend you have this.
  -Provision of content is INLINE<-- this="" is="" the="">

  In addition, you will need a browser for each of the Types MIME Plugin (if not, the browser may try to "Download" the file)
  Browsers can manage the types of images internally. Plugin Adobe can handle PDF files. I do not know Word/Excel.

  Yet once again, I don't remember the exact details, but that should cover most of it.

• How to create an item of the display of the Image with functions Apex?

  Hi everyone :)
  
  I'm working on the 4.1.1.00.23 Apex in an 11g database XE.
  
  I want to display an Image in a report, I can do this by using the ' + BLOB download Format mask + ", but the images displayed in the original format and I want to display the smaller.
  
  I read that you need to create a procedure, a SYNONYM and call them to the src of the img tag. as Zsuzsi Vadasz mentions here
  http://blog.hilandco.com/2010/05/How-to-show-BLOB-type-column-as-image.html
  
  But I remember that I was able to create items in reports with the functions of the Apex, I think they were APEX_ITEM package, so I want to know if there is a way to create the '+' display Image + element with a function of APEX.
  
  Thank you.

  Always specify if "report" means the report standard or interactive.

  This post was obsolete when it was written. Use the built-in support of BLOB.

  Resizing of the declarative BLOB images in reports is simple using CSS. Add a style sheet with:

  td[headers="PHOTO"] img {
    display: block;
    width: 40px;
    border: 1px solid #999;
    padding: 4px;
    background: #f6f6f6;
  }
  

  where the value of the PHOTO in the attribute selector is the ID of the image column table header. Define only a single dimension (in this case the width) will scale the image with the correct proportions. (Background, padding and border properties are just eye candy...)

  However, the scaling of the images in the browser in this way is a huge waste of bandwidth and product of lower quality images than to create good scaled down versions using image tools. Image download megapixel and then to reduce them to the size of the thumbnail result in needlessly pushing millions of bytes which will never be seen.

  For better performance and image quality, and where you need specific image scaling of the best approach is to use the ORDImage database object to produce thumbnail and preview automatically versions. Unfortunately, this is not possible in Oracle XE as multimedia is not included :-(.

  so I am very confused if the error is in the report or the table/data type definition itself.

  Or {noformat}) {noformat}

  The problem is in the settings of the P4_PICTURE element in the form on page 4. The Type of storage has been upgraded with WWV_FLOW_FILES of the Table, so the uploaded images were going to the repository of integrated files, not the BLOB on your CATEGORY table column. So the fundamental problem is that there are no images in your table to be included in the report.

  I changed the element P4_PICTURE Type of storage to a BLOB column specified in the attribute of the Source element, has added the additional column information and the IMAGESource and changed column PHOTO report 3 Format page mask download image, and the picture I have uploaded via the updated form the appears.

• Display of the Image on the form

  Hi friends
  
  I am developing payroll system, IN the form of d2k I want to see a picture of each employee,
  
  I had created with employee idno jpg files. Now I want that whenever I change the registration form should display no Image to the employee.

  Add an Image element in your basic block. It has map a BLOB type column that will store the image.
  When running, fill the element of this Image with the built-in function Read_Image_File(), and then save the block (commit). Forms will fill the BLOB column with your image.

• Loading Images in the BLOB.

  I wrote the pl/sql code for massive load of images in blob. When user tries to access from front end. some of the images are corrupted. means the white page, but for others, the image appears. Thus there is no size limitation on the images of the BLOB? for most of the images I'm Ranger is 20kb - 300 KB.
  
  Thanks in advance.

  There is a certain limit to the size of the BLOB, you can store. This limit is 4 GB (1 byte) *(block size) which means between 8 and 128 TB.

  I highly doubt that your question stores blobs in the database since Oracle you thought it unimportant to display information of DDL or DML version, no one can say for sure.

  I'd be much more suspicious of some tool, as mentioned, used to extract and display the.

• I love Personas, but I can't figure out how to display the part of the image that can be displayed at the bottom of the window; How can I activate this part?

  Beautiful image shows the upper part of the window, where the toolbars. But the part that can be displayed at the bottom of the screen (above the taskbar (I think it's called?)) does not appear and I can't remember/find a way to work in so that it is displayed too.

  "Personas" are basically dead. The name was changed to 'Lightweight thèmes' and the Mozilla seems to have lost all interest in this feature. IMO, it is corporate ADHD - build, promote, many users ignore the hook on the feature, of it do not continue to "show the love" and in two or three years 'kick on the sidewalk.

  Basically, the add-on bar went in Fx29 - so there is no image at the bottom. There is an extension that restore the bar of the add-on, and it seems that it supports Personas - based on the screenshots on the page to download add-on.

• Return to the display of the old images

  I've just updated to Firefox 11 and the new view of the image is horrible. When I go to a URL of the image (like this http://www.google.com.br/images/srpr/logo3w.png ), it is displayed with a dark background. It would be best that the background was gray soft... but it's too dark!

  Is it possible to use the display of the old images with white background or change the background color?

  You can install the add-on Old Style of Image by default (you don't have to restart Firefox to make it work)

• Display of the image without covering the circle behind

  Dear all,

  I have a great difficulty to display an image without covering the 'circle' behind. I have a circle in the center of the screen. The circle is the circle of draw by draw .vi. After a while, a table is displayed in the Center. But the circle behind is still required to demonstrate. I used playback .jpg, etc... to display the image. When the image is on, however, it covers the 'ring '. I can't do it in re-trace the circle on top of the image due to timing because of the sensitivity of the search. Could you please provide suggestions? Thank you very much!

  Yonghe

  How about two indicators of photo?  One on the top that contains the circle but otherwise has a transparent background.

  The indicator of the photo that you draw your other image is backward in your z-order of the controls on the front panel.

  You have this option in the indicator of the Image itself. Right-click on the indicator, you will get an option something like "Image Fit with indicator" (sorry I forgot the actual name)

• How can I use a function toolwindow or imaqBCGTransform on the image displayed by the image or the canvas area?

  Hello

  I use LabwindowsCVI8.5 & NI Vision. Recently, I met a problem when I tried to apply a toolwindow on diaplayed of the image by image or canvas block, the toolwindow successfully showed, but could not work. I knew that I can use imaqCreateImage & imaqDisplayImage functions to create the image on a new separate window, then, the two work well toolwindow & imaqBCGTransform, but I just want to know is possible to use the functions of Image processing with image display as part of the UIR or as a subgroup of experts? Coz I think it will be well conventional to see the image processed in this way.

  Thank you very much!

  URT

  I've always wondered why there is no control to an IUR for display of an image of Vision of OR...

  Anyway, there is a hack to incorporate a display image of NI Vision window in a Panel. It has already been discussed on this forum but I can't find the link more.

  It goes something like this:

  HWND window_handle, parent_handle;

  int image_window;
  int left, top, width, height;

  initialize the CVIRTE, etc.

  create the parent panel

  Panel = LoadPanel (...);

  get a new handle to display (optional, see the imaqGetWindowHandle documentation)

  imaqGetWindowHandle (& image_window);

  integrate into a parent group

  WINDOW_HANDLE = (HWND) imaqGetSystemWindowHandle (image_window);
  GetPanelAttribute (Panel, ATTR_SYSTEM_WINDOW_HANDLE, (int *) & parent_handle);
  SetWindowLong (window_handle, GWL_STYLE, WS_CHILDWINDOW);
  SetParent (window_handle, parent_handle);
  SetWindowLong (window_handle, GWL_STYLE, WS_CLIPSIBLINGS);

  Position the display where it should be displayed and resize
  imaqSetWindowSize (image_window, width, height);
  imaqMoveWindow (image_window, MakePoint (left, top));

  I hope this helps...
