Parameters

IconName

A member of the PdfStickyNoteAnnotationIcon enumeration. The name of the icon to be used when displaying the annotation.

Left

The horizontal (X) coordinate of the closest point to the currently defined origin, where the annotation's bounding box is to be located. The value is expressed in the current units specified by the SetMeasurementUnit method and it is related to the current page. For further assistance, please see the Remarks section below.

Top

The vertical (Y) coordinate of the closest point to the currently defined origin, where the annotation's bounding box is to be located. The value is expressed in the current units specified by the SetMeasurementUnit method and it is related to the current page. For further assistance, please see the Remarks section below.

Author

The title of the newly added annotation object, by convention it represents the author of the annotation.

Subject

The subject of the newly added annotation object.

Contents

The content of the newly added annotation object, that means the text displayed in the annotation's note and in its associated pop-up window.

Opacity

The opacity value of the newly added annotation object, from 0 (full transparency) to 1 (full opacity).

OpenPopup

A flag specifying whether the annotation should initially be displayed open, means whether the annotation's pop-up window should be opened. The initial value is false (closed).

Red

The amount of red color to be used for the resulting color. Use the value between 0 and 255.

Green

The amount of green color to be used for the resulting color. Use the value between 0 and 255.

Blue

The amount of blue color to be used for the resulting color. Use the value between 0 and 255.

PopupLeft

The horizontal (X) coordinate of the closest point to the currently defined origin, where the annotation's pop-up window is to be located. The value is expressed in the currently set units according to the currently used coordinate space.

PopupTop

The vertical (Y) coordinate of the closest point to the currently defined origin, where the annotation's pop-up window is to be located. The value is expressed in the currently set units according to the currently used coordinate space.

PopupWidth

The width of the annotation's pop-up window, expressed in the current units specified by the SetMeasurementUnit method.

PopupHeight

The height of the annotation's pop-up window, expressed in the current units specified by the SetMeasurementUnit method.

Return Value

It is recommend to use the GdPicturePDF.GetStat method to identify the specific reason for the method's failure, if any.

Please always ensure that you have selected the correct page using the GdPicturePDF.SelectPage method before adding a required annotation. Likewise, just to remind you that adding a text annotation increases the resulting count of all annotations in your document by two, as it is described above.

You also need to be aware that the values of coordinates and dimensions are expressed in the current units defined by the GdPicturePDF.SetMeasurementUnit method according to the current coordinate space defined by the GdPicturePDF.SetOrigin method.
