open-abap-pdf

Standalone PDF generation in ABAP

Pull requests welcome

Plan is to have the same code run on:

• Classic ECC
• Classic Steampunk
• Embedded Steampunk
• open-abap/transpiled

Features

• Create multi-page PDF documents
• Add text with customizable fonts (Helvetica, Times-Roman, Courier)
• Set text, draw, and fill colors (RGB)
• Draw shapes: lines, rectangles, circles
• Fluent API for method chaining
• Support for A4, Letter, and custom page sizes
• Unit conversion helpers (mm to points, inches to points)

Usage

Basic Example

DATA(lo_pdf) = zcl_open_abap_pdf=>create( ).
lo_pdf->add_page( ).
lo_pdf->set_font( iv_name = 'Helvetica' iv_size = 24 ).
lo_pdf->text( iv_x = 50 iv_y = 50 iv_text = 'Hello World!' ).
DATA(lv_pdf_string) = lo_pdf->render( ).

Fluent API

DATA(lv_pdf) = zcl_open_abap_pdf=>create(
  )->add_page(
  )->set_font( iv_name = 'Helvetica' iv_size = 16
  )->set_text_color( iv_r = 0 iv_g = 0 iv_b = 128
  )->text( iv_x = 100 iv_y = 100 iv_text = 'Blue Text'
  )->render( ).

Drawing Shapes

DATA(lo_pdf) = zcl_open_abap_pdf=>create( ).
lo_pdf->add_page( ).

" Draw a line
lo_pdf->line( iv_x1 = 50 iv_y1 = 100 iv_x2 = 200 iv_y2 = 100 ).

" Draw a rectangle (outline)
lo_pdf->rect( iv_x = 50 iv_y = 150 iv_width = 100 iv_height = 50 iv_style = 'D' ).

" Draw a filled rectangle
lo_pdf->set_fill_color( iv_r = 200 iv_g = 200 iv_b = 255 ).
lo_pdf->rect( iv_x = 50 iv_y = 220 iv_width = 100 iv_height = 50 iv_style = 'F' ).

" Draw a circle
lo_pdf->circle( iv_x = 300 iv_y = 200 iv_radius = 40 iv_style = 'DF' ).

DATA(lv_pdf) = lo_pdf->render( ).

Multiple Pages

DATA(lo_pdf) = zcl_open_abap_pdf=>create( ).

lo_pdf->add_page( ).
lo_pdf->set_font( iv_name = 'Helvetica' iv_size = 24 ).
lo_pdf->text( iv_x = 50 iv_y = 50 iv_text = 'Page 1' ).

lo_pdf->add_page( ).
lo_pdf->text( iv_x = 50 iv_y = 50 iv_text = 'Page 2' ).

DATA(lv_pdf) = lo_pdf->render( ).

Custom Page Size

" Letter size
lo_pdf->add_page(
  iv_width  = zcl_open_abap_pdf=>c_letter_width
  iv_height = zcl_open_abap_pdf=>c_letter_height ).

" Custom size in mm (converted to points)
lo_pdf->add_page(
  iv_width  = zcl_open_abap_pdf=>mm_to_pt( 100 )
  iv_height = zcl_open_abap_pdf=>mm_to_pt( 150 ) ).
