Is it possible to convert fabricjs svg output to pdf without rasterizing?

Question

We are building a web app where the user can make a design by using fabric.js and at the end he should receive a pdf file with his work.

At first, we tried to use JSPDF because it was prefered to have a cliente-side solution. However by doing pdf.addImage(canvas.toDataURL(),...) we are rasterizing the design.

In second place, we tried server side solution using WKHTMLTOPDF, sending canvas.toSVG(), but there are some issues with fonts and shapes rendering.

The designs are complex as they can have text, shapes, images and svg.

We also tried INKSCAPE (inkscape --without-gui --export-pdf ...), MPDF and MUPDF without good results. IMAGEMAGICK is not a solution has it also rasterize the design.

The main goal is to get a vector pdf, where it's possible to increase size and where the elements of the design are selectable, and if possible that pdf should be ready to print (300 dpi and cmyk)

Answer 1

Yes its possible using TCPDF library. Please check this ImageSVG api for more information for converting SVG to PDF. https://tcpdf.org/examples/example_058/

Answer 2

Export the canvas to svg and use pdflib to make the pdf.
