使用动态图像在Go中生成PDF

I am new to Go and actually trying to figure out the way to handle images in templates. My goal is to generate a barcode and insert it into a template I wrote. The program already use go-wkhtmltopdf to generate pdf but lacks about images. My main question is : what's nicest way to do this ? Should I generate an image in a public directory then insert into img src tag/property ?

Supposedly you might get away by using embedding image data directly into your HTML pages.

Thank you @kostix I'm pretty close. Now i'm stuck into another problem. I generated barcode (128), converted it to base64. When I pass it to my template like so : it breaks my png once I open the pdf. But if I take the content of base64BarcodeUrl and paste it directly as src to my img tag, it works like a charm. base64BarcodeUrl = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAASwAAABkEAAAAABJ+o5fAAABYUlEQVR4nOzSUYrCMBRA0ekw+99yhyLBUhIq2Pt3zo9V40si92/ffx6zba/XY+bxPGaPz8d317Xj/fksq9/P5p/Xr+Ze18/OtZoxO+/svqs51z1W97j7n+6eZ/vMzvvJfb/1+9woeBMWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGREBYJYZEQFglhkRAWCWGR+A8AAP//9bRAyVZD8C0AAAAASUVORK5C" Is there any issue I'm not aware about "injecting" some data ?
