I'm digitally capturing the signature.Are there any requirements for this?

digitally on your mobile device, there are some requirements in
place when submitting them as part of the transaction. They are
mainly in place to protect youin case those signatures are
required to resolvea disputed payment.
As a default, you shoulduse the utility and helper
functions directly available in the SDK. If you want to optimize
this even further, here are the general rules:
Converting the imageto black/white is
Cropping the image is
. Please always
use the complete canvas you use to capture the signature (including
texts, images or other elements)
Scaling the image down

the shortest side is
at least 400px.
Converting the image format to JPEG or

JPEG a quality of 90%+.
