FPDF vs. PDF Constructor vs. Python vs. TallPDF.NET 5.0 Comparison Chart

Using an XML grammar incorporating features of XHTML, CSS, and SVG, PDF Constructor creates single or multiple-page PDF documents using existing or dynamically-created raster, vector, and text content. Build PDFs with content that is ready to go to print. Use CMYK and spot colors. Specify the bleed and trim. Use Type 1, TrueType, or OpenType fonts, always embedded and optionally subset. Produce web or screen-ready documents with bookmarks, hyperlinks, actions, and JavaScript. You can even build complete Acrobat Forms dynamically. Include JPEG and TIFF images in any colorspace and resolution. Apply your choice of transformations to ensure the image fits correctly into your layout. Include SVG drawings directly or by reference. Specify individual pages or entire PDF documents as new content or as a template on which to add new elements. Paragraph and character styles based on CSS2 can be specified for flowable content.

Generate PDF on the fly, from scratch, use code, XML/XSL, or a combination. Central to TallPDF.NET is a consistent and intuitive object model consisting of layout classes like document, section, text paragraph, table, header, footer, etc. Among the specializations of class paragraph is drawing. Use it to draw many types of shapes such as lines, bezier curves, and even barcodes. Use pens and brushes to draw outlines and fills. Instead of building a Document programmatically, you can load it (partly) from XML. In general, you will use XSL to transform from a given XML schema to XML that can be consumed by TallPDF.NET. Headers and footers are added to each page that matches the specified page traits (first, odd, even, last). Include dynamic content such as current page number and total page count. Add Tables to a section. Add rows to a table. Add cells to a row and add any paragraph to a cell. Specify spacings, margins, borders, and backgrounds.
