PDF -> SVG

[doublex]

Problems to save a PDF to SVG.
Steps to reproduce:
wget https://github.com/coolwanglu/pdf2htmlEX/raw/master/test/browser_tests/fontfile3_opentype.pdf
node ./examples/node/pdf2svg.js /tmp/fontfile3_opentype.pdf

Result:
writeToFile() is never called - so result directory 'svgdump' remains empty.

The console reports:

(node:5841) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): ReferenceError: Image is not defined
(node:5841) DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
(node:5841) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): ReferenceError: Image is not defined

It's only triggered by this particular PDF file as other files I tested work just fine. Moreover, the file renders when the SVG back-end is used, so this issue appears to be caused by the conversion script.
