SftTree/OCX 8.0 - ActiveX Tree Control

GDI+

If GDI+ is available, the tree control supports additional features not otherwise available:

• Image support for PNG, TIFF, JPEG, GIF, Exif, EMF+, EMF (GDI+ images) with full support for alpha-blended (translucent and semi-transparent) images (e.g., NETImageObject)
• Rounded outline rectangle with gradient fill for selected items, highlighted items (flyby highlighting) or drop target items (Items.OutlineStyle)
• Transition effects for expand/collapse buttons and tree lines are used when the mouse enters/leaves the tree control (MouseOverTransitionEffect)

GDI+ is always available on all supported Windows platforms.

If GDI+ support is not available, the features are simply disabled and alternate presentation methods are used, if available.

An application can test whether GDI+ is available using the GDIPlusSupport property.
