#include <GDIPlus.au3>
_GDIPlus_PathBrushSetLinearBlend ( $hPathGradientBrush, $fFocus [, $fScale = 1] )
| $hPathGradientBrush | Pointer to a PathGradientBrush object |
| $fFocus | Number in the range 0.0 to 1.0 that specifies where the center color will be at its highest intensity |
| $fScale | [optional] Number in the range 0.0 to 1.0 that specifies the maximum intensity of center color that gets blended with the boundary color |
| Success: | True. |
| Failure: | False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
