Developer Notes

Switched to Electron.js

I first wanted to use this as an chrome app. But later switched to Electron.js. So, some of the code is very weirdly written. I plan to modify them soon. So, please pardon the bad practices.

Modifications of pdf.js

renderTextLayer() was not accessible to text_layer_builder.js. So I modified pdf.js to expose this function to all as publicRenderTextLayer(). Also changed text_layer_builder.js to call this new function.
