MergeFieldImageDimension

Inheritance: java.lang.Object

All Implemented Interfaces: java.lang.Cloneable

public class MergeFieldImageDimension implements Cloneable

Represents an image dimension (i.e. the width or the height) used across a mail merge process.

To learn more, visit the Working with Fields documentation article.

Remarks:

To indicate that the image should be inserted with its original dimension during a mail merge, you should assign a negative value to the getValue() / setValue(double) property.
