About

GEN_PDF is PL/SQL based generator for PDF.

GEN_PDF is mix of WPDF(1.4.8b) and AS_PDF3.

Why ?

• WPDF is great for setting position of custom tables, colors, borders ...
• AS_PDF3 is great for importing fonts into PDF

GEN_PDF is set to work on apex. Fonts and images are stored in WWV_FLOW_FILES or CUSTOM table, so there is no need to use UTL.FILE package (like in AS_PDF3) and there is also no need for "ordsys.ordImage" (like in PL_FPDF which don't work on XE db).

You can find more info inside "GEN_PDF.pks"

How to use it

Inside package are few samples which demonstrate almost all functionality of GEN_PDF tool.

List of samples inside package :

• procedure emp_demo
• procedure fonts_demo
• procedure barcode_demo
• procedure rotate_demo
• procedure images_demo
• procedure testHeader
• procedure chart_demo

Run sample:

Add apex Non-Modal dialog page and before header in process add PL/SQL code

BEGIN
  gen_pdf.emp_demo();
  apex_application.stop_apex_engine;
END;

Needed Rights

For last sample "chart_demo" to work you need :

1. Grant on UTL_HTTP

  GRANT EXECUTE ON UTL_HTTP TO <USER>;

2. ACL permissions to get Google chart and QR code

     BEGIN
        DBMS_NETWORK_ACL_ADMIN.CREATE_ACL (
            acl          => 'chart.xml',
            description  => 'Permissions to get chart image',
            principal    => 'APEX_050000', -- APEX_SCHEMA depands on APEX version
            is_grant     => TRUE,
            privilege    => 'connect');
        COMMIT;
     END;
     /
     BEGIN
        DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL (
            acl          => 'chart.xml',
            host         => 'chart.googleapis.com');
        COMMIT;
        END;
     /
     BEGIN
        DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL (
            acl          => 'chart.xml',
            host         => 'zxing.org');
        COMMIT;
     END;
     /

In case you need to save file on server you can enable procedure "save_pdf".

If you need reed file from server "font or pdf" than enable function "file2blob".

For this to work you need grant on UTL_FILE.

  GRANT EXECUTE ON UTL_FILE TO <USER>;
