Delphi 7 to 13 & C++ Builder No DLLs

sgcPDF, a Pure Pascal PDF Library for Delphi & C++ Builder

Create, edit, view, render, extract, encrypt, sign, redact and validate PDF files with components written entirely in Object Pascal. There is no DLL to deploy and no external PDF engine: the parser, writer, fonts, image decoders, renderers and cryptography are compiled into your application. The core runs on Windows, Linux, macOS, iOS and Android, with a VCL viewer control, a FireMonkey viewer and a raster renderer for servers. Full source code is included.

BEFORE YOU START

Three Things Worth Knowing First

Nothing to install on the target machine

sgcPDF does not wrap PDFium, Ghostscript, a COM server or any other native library. Parsing, writing, font embedding and subsetting, image decoding, rendering, encryption and signing are implemented in the sgcPDF_*.pas units, so your executable is the whole deployment.

The core units have no VCL or FMX dependency, so the same code runs in a console tool, a Windows service, a Linux daemon or a web server.

Platform scope

Which parts run where

Creation, editing, text and image extraction, forms, encryption, signatures, redaction, PDF/A and the raster renderer compile for Windows and Linux64, and for macOS, iOS and Android. The GDI renderer, the exporter and the VCL viewer controls are Windows only, and TsgcPDFViewerFMX covers Windows, macOS, iOS and Android.

Advanced signatures

PAdES through sgcSign, basic signing built in

sgcPDF signs and verifies PDF files on its own with a PFX certificate. For PAdES baseline levels B-B, B-T, B-LT and B-LTA, and for keys held in smart cards, the Windows certificate store or cloud HSMs, the optional TsgcPDFPAdESSigner bridge uses the key providers of sgcSign, which is licensed separately.

WHAT IS IN THE BOX

One Library for the Whole PDF Lifecycle

From the first page you write to the signed, archived and redacted file you hand over, every step runs in the same Object Pascal code base.

Create: Documents from code, HTML or a canvas

Pages, text in the 14 standard fonts or embedded and subset TrueType and OpenType fonts, images (JPEG, PNG, BMP, TIFF), lines, curves, gradients, tables that flow across pages, barcodes and QR codes, annotations, bookmarks and optional content layers. TsgcPDFHTMLRenderer turns HTML with CSS into paginated PDF, and TsgcPDFCanvas and EMF playback convert existing drawing code.

Edit: Change files you did not write

Watermarks, headers, footers, page numbers and stamps, merge and split, extract, insert, delete, rotate and reorder pages. Incremental save appends a new revision to the original file, which keeps earlier signatures valid.

View & render: VCL and FMX viewers, plus a server renderer

A VCL viewer control with thumbnails, outline, text selection, search, form filling and printing, a FireMonkey viewer for Windows, macOS, iOS and Android, and a pure Pascal raster renderer that turns pages into PNG on Windows and Linux servers with no GDI.

See the features →

Extract: Text, positions and images

Plain text per page or for the whole document, text fragments with coordinates, font and size, and the images of a page decoded to PNG, JPEG or BMP. Decoders cover Flate, LZW, ASCII85, RunLength, JPEG (baseline and progressive), JPEG 2000, CCITT G3/G4 and JBIG2.

See the features →

Secure & sign: Encryption, signatures, redaction

RC4 40/128, AES-128 and AES-256 password encryption, certificate (public key) encryption, digital signatures with visible fields and timestamps, PAdES B-B, B-T, B-LT and B-LTA through the sgcSign bridge, signature verification, and true redaction that removes content instead of covering it.

See the features →

Comply: PDF/A, PDF/UA, tagged PDF, Factur-X

PDF/A-1, PDF/A-2 and PDF/A-3 output in levels a and b with a built in validator, tagged PDF with a structure tree and alternate text, PDF/UA-1 checks, embedded files with PDF/A-3 relationships, and Factur-X, ZUGFeRD and XRechnung e-invoice embedding.

QUICK START

A Few Lines of Delphi

Every sample on this page is taken from a program that was compiled against the sgcPDF sources and run. Coordinates are in PDF points (1/72 inch) with the origin at the bottom left corner of the page.

procedure CreateHelloPDF(const AFileName: string);
var
  oPDF: TsgcPDFDocument;
  oPage: TsgcPDFPage;
begin
  oPDF := TsgcPDFDocument.Create;
  try
    oPDF.Info.Title := 'Hello sgcPDF';
    // A4 portrait: 595 x 842 points, origin at the bottom left corner
    oPage := oPDF.AddPage(595, 842);
    oPage.DrawTextColor('Hello sgcPDF', 50, 780, sfHelveticaBold, 24, 0, 0.2, 0.6);
    oPage.DrawLine(50, 770, 545, 770, 1.5);
    oPage.DrawText('A PDF written in pure Pascal.', 50, 740, sfHelvetica, 12);
    oPDF.SaveToFile(AFileName);
  finally
    oPDF.Free;
  end;
end;

procedure StampExistingPDF(const AInput, AOutput: string);
var
  oEditor: TsgcPDFEditor;
  oWatermark: TsgcPDFWatermarkOptions;
begin
  oEditor := TsgcPDFEditor.Create;
  try
    oEditor.LoadFromFile(AInput);

    oEditor.SaveToFile(AOutput);
  finally
    oEditor.Free;
  end;

  try
    oPDF.LoadFromFile(APDFFile);
    oPage := oPDF.Pages[0];
    // pure Pascal rasterizer: no GDI, runs on Windows and Linux servers
    oRenderer := TsgcPDFRendererRaster.Create;
    try
      oRenderer.RenderPageToPNG(oPDF.Parser, oPage.PageDict,
        Round(oPage.Width * ADPI / 72), Round(oPage.Height * ADPI / 72),
        APNGFile);
    finally
      oRenderer.Free;
    end;
  finally
    oPDF.Free;
  end;
end;
