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.

• javascript
• jspdf

• jspdf converts transparency into black. so if you can set a background color to white you will be all set. I'm not sure how you are sending you're png to jspdf but can you wrap it in a white div. or if you use imagemagic $im->setImageBackgroundColor('white'); I'm sure there must be an equivalent – jkuhns5 Commented Aug 16, 2016 at 14:31

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

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