Name: noOp

Type: keyword

Syntax: noOp

Summary: Specifies one of the <transfer mode|transfer modes> that can be used with the <ink> <property>.

Introduced: 1.0

OS: mac,windows,linux,ios,android

Platforms: desktop,server,web,mobile

Example:
set the ink of field "Alerts" to noOp

Description:
Use the <noOp> <keyword> to make an <object> transparent.

The <ink> <property> determines how an <object|object's> colors combine with the colors of the <pixels> underneath the <object> to determine how the <object|object's> color is displayed.

When the <noOp> <transfer mode> is used, the <object|object's> background and border are not drawn and seem to disappear, letting <object|objects> behind it show through. (Text is still drawn.)

>*Tip:*  <graphic(object)|Graphics> whose <ink> is set to <noOp> are transparent, but (unlike <graphic(object)|Graphics> whose <opaque> <property> is set to false) they still intercept mouse clicks within the <graphic(object)|graphic's> outline. To create an invisible hot spot with a non-rectangular shape, use a <curve> or <polygon> <graphic(keyword)> and set its <ink> property to <noOp>.
