wPDF

What's New in V3.0?

• Support for standard brush styles (hatching)
• TransparentBitBlt
• Automatic reuse of the same image data. This way, when you export a document which often uses a logo the PDF file will be significantly smaller
• Creation of PDF/A complient PDF files (with added meta data and PDF tagging when you use it with WPTools)
• Support of CID fonts (known as "unicode" support)
• Binary Data embedding: You can store the document source which was used to create a PDF file within this PDF file. When you use WPTools for the PDF creation you can store the RTF source document inside of the created PDF data, the user only has to click on an icon to extract this document. This can be a great feature if you use it to embed programming examples within your programming manual

Overview

wPDF converts enhanced metafiles to PDF while preserving the vector and text information. This results in small PDF files which can be printed at high resolution, thus making wPDF superior to other solutions which convert embedded metafiles into bitmaps. wPDF supports the usual PDF features, including compression and 128 bit encryption and it was the first Delphi library to allow embedding of font subsets to reduce file size even further.

Code

The code needed for to create a PDF file is very similar to that needed for printing:

const Resolution = 72;

WPPDFPrinter1.BeginDoc; // Starts a new document

try

WPPDFPrinter1.StartPage( // start a page of a certain page

Round(8.5*Resolution), 5*Resolution, Resolution, Resolution, 0);

DrawPage(WPPDFPrinter1.Canvas); // subprocedure to draw to the TCanvas

WPPDFPrinter1.EndPage; // close the page

finally

WPPDFPrinter1.EndDoc; // close the document

end;

If you are using WPTools file creation can be done with just one line of code:

WPPDFExport1.Print;

Even though the export functions quickly, there's nothing missing from wPDF. Compression, encryption, embedded fonts, charsets (eastern European, Greek and Cyrillic) are all supported. Thumbnails can be created and you can add code to create outlines and hyperlinks. Graphics can be embedded using deflate or JPEG compression.
