You can automate that process by using a PDF editing library. Use for example the PDFLib 2.1 which is an open source project. Download it ... Obviously, this export cannot be imported into the new structure it will not fit. This check prevents that from occurring. If you remember, I mentioned that we can change the behavior of the object identifier assigned to an object instance. Instead of having the system generate a pseudo primary key for us, we can use the natural key of an object. At first, this might appear self-defeating the SYS_NC_OID$ column will still appear in the table definition in SYS.COL$ and, in fact, it will appear to consume massive amounts of storage as compared to the system-generated column. Once again, however, there is magic at work here. The SYS_NC_OID$ column for an object table that is based on a primary key and not system generated is a virtual column and consumes no real storage on disk. Here is an example that shows what happens in the data dictionary and demonstrates that there is no physical storage consumed for the SYS_NC_OID$ column. We ll start with an analysis of the systemgenerated OID table: ops$tkyte@ORA11GR2> create table people of person_type 2 / Table created. ops$tkyte@ORA11GR2> select name, type#, segcollength 2 from sys.col$ 3 where obj# = ( select object_id 4 from user_objects 5 where object_name = 'PEOPLE' ) 6 and name like 'SYS\_NC\_%' escape '\' 7 / NAME TYPE# SEGCOLLENGTH ------------------------- ---------- -----------SYS_NC_OID$ 23 16 SYS_NC_ROWINFO$ 121 1 ops$tkyte@ORA11GR2> insert into people(name) 2 select rownum from all_objects; 48217 rows created. ops$tkyte@ORA11GR2> exec dbms_stats.gather_table_stats( user, 'PEOPLE' ); PL/SQL procedure successfully completed. ops$tkyte@ORA11GR2> select table_name, avg_row_len from user_object_tables; TABLE_NAME AVG_ROW_LEN ------------------------------ ----------PEOPLE 23 vb.net itextsharp add image to pdf: How to add a logo/ image to a existing PDF file using ASP.

Whether it s the latest programming library, power saw, or scalpel, your blog readers appreciate a good product or service review. In fact, many a well-known blog consists of just product reviews and announcements; two examples are Gizmodo (www.gizmodo.com) and Engadget (www.engadget.com). Here are some common-sense pointers about doing blog reviews: Back up your opinions. If you hate a product, explain why. If you love a new release, share why with your readers. Be up-front with your readers. Just exactly how did you get that item Did you buy it, rent it, or get if from the manufacturer Your credibility is at stake, and your readers will want to know. Write for your readers, not the vendors. If you do review products, you ll quickly find everyone who makes a product or service will want you to tell their story their way. Don t go that way. People who read your blog want your opinion, not a regurgitation of marketing hype. Show and tell. Product reviews are much more interesting and, frankly, easier to do with a healthy helping of images.

We see here that the average row length is 23 bytes: 16 bytes for the SYS_NC_OID$ column and 7 bytes for the NAME column. Now, let s do the same thing, but use a primary key on the NAME column as the object identifier: ops$tkyte@ORA11GR2> CREATE TABLE "PEOPLE" 2 OF "PERSON_TYPE" 3 ( constraint people_pk primary key(name) ) 4 object identifier is PRIMARY KEY 5 / Table created. ops$tkyte@ORA11GR2> select name, type#, segcollength 2 from sys.col$ 3 where obj# = ( select object_id 4 from user_objects 5 where object_name = 'PEOPLE' ) 6 and name like 'SYS\_NC\_%' escape '\' 7 / NAME TYPE# SEGCOLLENGTH ------------------------------ ---------- -----------SYS_NC_OID$ 23 81 SYS_NC_ROWINFO$ 121 1 According to this, instead of a small 16-byte column, we have a large 81-byte column! In reality, there is no data stored in there. It will be null. The system will generate a unique ID based on the object table, its underlying type, and the value in the row itself. We can see this in the following: ops$tkyte@ORA11GR2> insert into people (name) 2 values ( 'Hello World!' ); 1 row created. ops$tkyte@ORA11GR2> select sys_nc_oid$ from people p; SYS_NC_OID$ ------------------------------------------------------------------------------F610733A48F865F9E030007F0100149A00000017260100010001002900000000000C07001E01000 02A00078401FE000000140C48656C6C6F20576F726C642100000000000000000000000000000000 0000 ops$tkyte@ORA11GR2> select utl_raw.cast_to_raw( 'Hello World!' ) data 2 from dual; DATA ------------------------------------------------------------------------------48656C6C6F20576F726C6421 ops$tkyte@ORA11GR2> select utl_raw.cast_to_varchar2(sys_nc_oid$) data 2 from people; DATA ------------------------------------------------------------------------------<garbage bits and bytes..>Hello World! itextsharp add image to existing pdf vb.net Add Water mark image to PDF using iTextsharp , C# and VB .

10 Jul 2013 ... In this blog you will learn how to add an image in pdf document using itextsharp in asp. net . What is ITextSharp - iTextSharp is a free and open source assembly which helps to convert page output or html content in pdf file. Start visual studio and create a new website in asp. net and add these 2 dll in solution. You can also disable Time Machine backups altogether. To do so, click the Time Machine preference pane, and use the slider to move the backup status to the Off position (see Figure 18 6). If we select out the SYS_NC_OID$ column and inspect the HEX dump of the string we inserted, we see that the row data itself is embedded in the object ID Converting the object ID into a VARCHAR2, we can just confirm that visually Does that mean our data is stored twice with a lot of overhead with it No, it is not it is just factored into that magic thing that is the SYS_NC_OID$ column upon retrieval Oracle synthesizes the data upon selecting from the table Now for an opinion The object relational components (nested tables and object tables) are primarily what I call syntactic sugar They are always translated into good old relational rows and columns I prefer not to use them as physical storage mechanisms personally There are too many bits of magic happening side effects that are not clear. add image to pdf itextsharp vb.net #2 – VB.Net iTextSharp Tutorial – Add an image to a document ...
