• Errors during download of images in BLOB

  We have Oracle database 11g in our environment. I get errors when downloading image in BLOB. The steps are:

  1) I created the table like:

  CREATE TABLE test_image

  (

  Identification NUMBER, image_filename, VARCHAR2 (50), picture BLOB);

  2) create or replace

  PROCEDURE insert_image_file (p_id NUMBER, p_image_name IN VARCHAR2)

  IS

  src_file BFILE.

  dst_file BLOB;

  Directory of lgh_file;

  BEGIN

  src_file: = BFILENAME ("TEST_DIR", p_image_name);

  -Open the file

  DBMS_LOB. FileOpen (src_file, DBMS_LOB.file_readonly);

  -determine the length

  lgh_file: = DBMS_LOB.getlength (src_file);

  -Read the file

  DBMS_LOB. LoadFromFile (dst_file, src_file, lgh_file);

  -update the blob field

  UPDATE test_image SET image = WHERE ID = p_id AND image_filename dst_file is p_image_name;.

  -close file

  DBMS_LOB. FileClose (src_file);

  END insert_image_file;

  3) I did an insert-insert into test_image values(1,'2.tif',null);

  4) when I call the procedure-

  Insert_image_file(1,'2.tif') EXECUTE, I get errors like:

  Error from line 7 in the command:

  EXECUTE insert_image_file(1,'2.tif')

  Error report:

  Hello how are you? I am new to Oracle application development MAF and I try to display an image stored in the database with BLOB format, and I would like to know how she could show this picture in a form.

  You have a binary encoded in Base64. If you add this string before the data "imagen", " data:image/png;base64, " then you can use this string as the source attribute in the component of the image.

• Image of BLOB in the subquery of report

  Hi guys,.

  It seems like it should be a simple problem, but I can't get this to work.

  I have an interactive report, in which I want to display a picture of BLOB columns in view image.

  The table contains the details of the project.

  Table B contains the categories of projects (including image BLOB and required image columns).

  Report interactive sql:

  select a.id,
   a.name,
   (select dbms_lob.getlength(b.blob_icon) from table b where b.id = a.category_id) icon
  from
  table b
  

  In the interactive report, I chose the format BLOB in the image column and fill in the required fields with the details of table b for the image, including columns of type MIME table, ID, etc..

  Again... the image column is empty in the report. Am I missing something? It seems that I use it as expected?

  The query as shown is not valid. The projection includes columns of table A, but only table B is referenced in the FROM clause. Publish the actual query.

  Why you try to use a scalar subquery here? Is it because table B does not contain a line for each line in the table? In this case, use an outer join. The request must also contain the primary key column referenced in the BLOB format mask:

  select
      a.id a_id
    , a.name
    , dbms_lob.getlength(b.blob_icon) icon
    , b.id
  from
      table_a a
        left outer join table_b b

  How do you define PHOTO_DIR (which was the CREATE DIRECTORY statement)?
  Is the path to PHOTO_DIR a directory that exists on the server (and not on your client machine)?
  The user of the operating system that is running the database on the server Oracle has access to this directory on the server? Can you connect to the server as the operating system user that runs the Oracle database and open the file on the server?

• 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.

• How to detect multiple points of laser on the image

  Consider I have a picture with several spots dark bright laser. I want to find the center of gravity of each laser spot and return the coordinates of each spot.

  Currently, I managed to detect an single spot to grab an image, adjustment of the threshold (threshold IMAQ) and find the center of gravity (centroid IMAQ).

  However, when I have several points of light, this method gives me the center of gravity of all tasks combined. Should what technique I use to detect the center of gravity of each individual laser?

  Thanks in advance.

  Try to use blob analysis.  Make a fast threshold, which should give you a place for each laser.  Blob analysis allows to get the center of each BLOB.  Use the function of Center of gravity to locate the exact gravity Center, if the center of the BLOB is not good enough.

  You should be able to save time by recording the previous values of the center of gravity.  Lasers are moving very quickly, their new locations should be near their old location.

  If it is still too slow, understand what part takes the most time.  If it's the center of gravity, I am able to suggest other ideas.
