I need create digital signature PDF file. I use JS (CryptoPro PDF).

});
the function parameter appearanceSettings is a JSON string:
{"pageNumber":0,
"coords":[10,10,350,100],
"customAppearance":
{"font":"Arial",
"borderStyle":"beveled",
"borderColor":["RGB",0,0,255],
"borderWidth":2,
"textFields":[{"text":"myText",
"coords":[20,90,330,60]
},
{"type":"CN",
"coords":[10,70,300,50],
"fontSize":11
}
]
}
}
How change property textFields (textColor ....)?
