Specifies how the XRSparkline control should be internally rendered in a report.
Use this enumeration's members to determine whether the specified XRSparkline control should be rendered as an image or as a metafile in a report. This enumeration is used by the XRSparkline.ImageType property.
The control is rendered as a bitmap. In this case the quality of the rendered image is sometimes poor, but it allows a control to be drawn more precisely.
The control is rendered as a metafile. In this case the quality of the rendered image is always good, but in some cases some details of the control may be lost.
