PL/PDF program package could be used to generate the following:

Printouts (bills, delivery notes, etc.) from ERP systems
Dynamic, customized product catalogues
Financial reports
Reports for applications developed in HTML DB

With PL/PDF you can easily produce:

Page formats: unit of measures, headers, footers, margins, page numbers
Automatic page breaks
Use of rows and columns
Shapes: lines, circles, ovals, rectangles
JPEG pictures from the database
Fonts: type, size, colour, style, TrueType
Use of colours
Compression of pages

Other advantages of PL/PDF:

No third-party software or any extra installation is needed, only uses tools installed by an Oracle database
Directly accesses data from the database, it does not need ODBC/JDBC connectors
Centralized document creation, can be scheduled
Pictures stored in an Oracle database can be inserted into any PDF document

Here is a basic example (the infamous "Hello World!") using PL/PDF.

1. Create the PL/SQL package:

CREATE OR REPLACE package test is
procedure pdf;
end;
/

CREATE OR REPLACE package body test is
procedure pdf is
    l_blob blob;
begin
    plpdf.init; -- initialize
    plpdf.NewPage; -- new page
    plpdf.SetPrintFont('Arial',null,10); -- set font
    plpdf.PrintCell(10,40,'Hello World!'); -- Print a text
    plpdf.SendDoc(l_blob); -- save the generated document

    -- print
    owa_util.mime_header('application/pdf',false);
    htp.p('Content-Length: ' || dbms_lob.getlength(l_blob));
    owa_util.http_header_close;
    wpg_docload.download_file(l_blob);

end;
end;
/

2. After creating the PL/SQL package, the document can be reached through a browser (if MOD_PL/SQL is installed and the Oracle HTTP server is running) at the URL: http://server:port/pls/DAD/test.pdf, where DAD is the Database Access Descriptor. The result is: test.pdf

The data source for data prepared in a dynamically created PDF document is usually a database, often an Oracle RDBMS. On the other hand, it is a general requirement to store the conditions under which the dynamic generation took place as well as the generated document. It is practical to store these data in a database as well, for easy access in the future. If both the source and target of the generated document is in the database then it is best to actually generate the document in the database also. If the database we are talking about is an Oracle database, then the best tool to use for the dynamic generation is the PL/SQL language because:

It is integrated with the Oracle database; therefore it is the safest, quickest and most efficient way of interacting with the database
It is a well-known language for anyone who works in an Oracle environment; therefore there is no need for developers to learn a new programming language
There is no need for a separate server (physical or virtual i.e. separate software); therefore the cost of hardware and operation is reduced. Also, because of the simplicity of the infrastructure, the risks are reduced.

When creating the PL/PDF package, it was a basic goal to allow Oracle developers to develop without in depth knowledge of the structure of the PDF document. In a PDF document, elements are not automatically placed on the page as in an HTML document (e.g. in case of a table), so for each element the actual place where it is required to appear must be specified. To facilitate development, the following two concepts were introduced:

Actual position: the actual X and Y coordinate on a page, where the object will be placed
Cell: a rectangular area on the page, where text can be placed. The cell will have an actual coordinate, but the text will be placed automatically according to where the cell is. Using this method, the PDF document is a series of cells.

Here is a simple example:
...
-- header
plpdf.SetPrintFont('Arial','B',12);
plpdf.SetColor4Filling(200,220,255);
plpdf.PrintCell(20,10,'ROWNUM','1',0,'C',1);
plpdf.PrintCell(40,10,'OWNER','1',0,'C',1);
plpdf.PrintCell(100,10,'OBJECT NAME','1',1,'C',1);

-- the data
plpdf.SetPrintFont('Arial',null,12);
for f_obj in (select rownum, owner, object_name from all_objects where rownum < 100) loop
plpdf.PrintCell(20,10,to_char(f_obj.rownum),'1',0);
plpdf.PrintCell(40,10,f_obj.owner,'1',0);
plpdf.PrintCell(100,10,f_obj.object_name,'1',1);
end loop;
...

PL/PDF also provides tools that give further help in formatting the document, such as automatic page breaks. If necessary, the developer can directly specify where a certain text should be placed to achieve a required format.

Of course apart from text, a number of other objects can also be placed in a PDF document:

Line (thickness and color can be specified)
Ellipse, circle (line, color and fill can be specified)
Rectangle (line, color and fill can be specified)
JPEG picture (size can be specified)

Using PL/PDF not only the cost of hardware and operation, but also development timeframe and consequently the cost of implementation is reduced.
