JSPDF在转换后的PDF中添加黑色背景

Question

When I use JSPDF to convert from a PNG to PDF, wherever the PNG is transparent, JSPDF puts a black background in. Where can I find the code in the library to change this from black to white?

I am open to suggestions other than updating the library.

Answer 1

I solved this by using before I drew the image to the canvas.

context.fillStyle = "#FFFFFF";
context.fillRect(0,0,width,height);
