In This Topic
SetFormFieldRichText Method (GdPicturePDF)
In This Topic
Sets the RichText flag of a required form field, here a text field, that is specified by its unique form field's identifier and it is related to the currently loaded PDF document. As stated, this flag is only specific to text fields, so this method is explicitly applicable to text form field objects.

If this flag is set, then the value of this text field should be represented as a rich text string. For further assistance, please refer to the PDF Reference, Section "Rich Text Strings".

Parameters

FieldId
A unique form field identifier specifying a required form field object. You can obtain this identifier using these methods: AddTextFormField(Single,Single,Single,Single,String,String,Boolean,String,Single,Byte,Byte,Byte), GetFormFieldId or GetFormFieldChildID.
RichText
Set this parameter to true, if you want to enable the RichText flag, otherwise set it to false to disable it.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.
