</div></div>Does that mean you use jQuery SVG to generate the SVG and build/use<br>
another rendering library that generates the PNG/PDF? Why not just<br>
build a converter? That seems like a more reusable solution.<br>
<div><div></div><div class="h5"><br>
</div></div></blockquote></div>I use GD extension to generate PNGs and will be using TCPDF (which is already included in PMA) to generate PDFs. Since both GD and TCPDF support rendering basic shapes, I find this approach needs only few additional lines of code, which would not have been the case if I am to build a converter.<br clear="all">
