When I load the signaturePad image into image, i.e.
img1.src = mySigPad_signaturePad.toDataURL("image/jpeg",0.8);, the image background is black, which is expected, due to transparent backgrounds on jpeg’s are replaced with the color black.
Now here is the issue, on BS4 signaturePad, in the properties window “BackgroundColor” set to white fixes it, however this doesn’t work on BS5 ??
