SilkySignature

A smooth and silky signature pad for android.

Updates

Method added

getTransparentSignatureBitmapTrimOnStrokes() - returns a transparent signature bitmap, but the triming process is way faster.
insertStaticText(String text) - adds a text at the lower end of the sign-pad (text-attributes cannot be modified).
addStaticText(String text)(String text) - adds a text at the lower end of the sign-pad and returns the TextBuilder, where you can changed text-attributes. You have to run "build" to add the text.
setHintText(String/int text) - adds a hint-text at the middle of the sign-pad, which dissappears as soon as someone signs (will be automaticaly shown when it is cleared again).
setHintTextColor(int color) - sets the color of the hint-text.
setHintTextColorRes(int color) - sets the color of the hint-text.
setHintBorderColor(int color) - sets the border-color of the hint-text.
setHintBorderColorRes(int color) - sets the border-color of the hint-text.
