I'm using a image inside the HMTL code like here below:

</html>When I'm using the wkhtmltopdf to convert it to PDF, some of the SVG paths is missing. Has anyone had the same problem? Some workaround to this issue?
I tried using the relative path, full path, base64 source and the SVG by itself within the code (as in the example).
wkhtmltopdf version: 0.12.4
482
So not a exact solution but a far better alternative now is to use a chrome in headless mode
$ chrome --headless --disable-gpu --print-to-pdf test.html
[0427/011400.636954:WARNING:dns_config_service_posix.cc(174)] dns_config has unhandled options!
[0427/011400.638406:ERROR:gpu_process_transport_factory.cc(1007)] Lost UI shared context.

Also if you want better control on the process, you would use NodeJS and puppeteer
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto('https://news.ycombinator.com', {waitUntil: 'networkidle2'});
await page.pdf({path: 'hn.pdf', format: 'A4'});
await browser.close();
})();
A workaround is to convert the .SVG files to .PNG files before converting to .PDF. The .SVG code can be extracted via AgilityPack or read the files as a string. Then use the Svg library to convert to .PNG as follows:
var svg = SvgDocument.FromSvg<SvgDocument>(svgXmlAsString);
var bitmap = svg.Draw();
var codec = "image/png".ParseImageCodecInfo();
// intermediaryStream required due to image.Save attempting read access
using (var intermediaryStream = new MemoryStream())
{
bitmap.Save(intermediaryStream, codec);
intermediaryStream.Position = 0;
await intermediaryStream.CopyToAsync(responseStream);
await intermediaryStream.FlushAsync();
await responseStream.FlushAsync();
}
