#include <GDIPlus.au3>
_GDIPlus_LineBrushSetLinearBlend ( $hLineGradientBrush, $fFocus [, $fScale = 1] )
| $hLineGradientBrush | Pointer to a LinearGradientBrush object |
| $fFocus | Number in the range 0.0 to 1.0 that specifies the position of the ending color |
| $fScale | [optional] Number in the range 0.0 to 1.0 that specifies the percentage of the gradient's ending color that gets blended, at the focus position, with the gradient's starting color. The default value is 1, which specifies that the ending color is at full intensity |
