FPDF vs. PDF Constructor vs. Python vs. pdfmake 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.

pdfmake is a PDF document generation library for server-side and client-side usage in pure JavaScript. Print PDFs directly in the browser or delegate them to your NodeJS backend. Use the same document definition in both cases. Forget about manual x, and y calculations. Declare document structure and let pdfmake do the rest. Use paragraphs, columns, lists, tables, canvas, etc. Declare your own styles, use custom fonts, build a DSL, and extend the framework. Line-wrapping, text-alignments (left, right, centered, justified), numbered and bulleted lists, margins, images, and vector graphics. Convenient styling, style inheritance, and custom style dictionaries. Auto/fixed/star-sized/percentage columns widths, col-spans, and row-spans, headers automatically repeated in case of a page-break, non-breaking rows, and non-breaking sections keeping headers and rows together. Static or dynamic content, page numbers, and page count.
