GetFormFieldRichText Method (GdPicturePDF)
In This Topic
Returns, if the RichText flag of a required form field, here a text field, is set. The text field 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".
Syntax
'Declaration
Public Function GetFormFieldRichText( _
ByVal As Integer _
) As Boolean
public bool GetFormFieldRichText(
int
)
public function GetFormFieldRichText(
: Integer
): Boolean;
public function GetFormFieldRichText(
: int
) : boolean;
public: bool GetFormFieldRichText(
int
)
public:
bool GetFormFieldRichText(
int
)
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.
Return Value
true if the RichText flag of the specified text field is set, otherwise false. The
GetStat method can be subsequently used to determine if this method has been successful.
Example
