Sets the blend factors and the blend positions of a path gradient brush
#include <GDIPlus.au3>
_GDIPlus_PathBrushSetBlend ( $hPathGradientBrush, $aBlends )
| $hPathGradientBrush | Pointer to a PathGradientBrush object |
| $aBlends | Array of blend factors and blend positions: [0][0] - Number of blend factors and blend positions [1][0] - Factor 1 [1][1] - Position 1 [2][0] - Factor 2 [2][1] - Position 2 [n][0] - Factor n [n][1] - Position n |
| Success: | True. |
| Failure: | False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
Each factor and position in the array should be in the range 0.0 to 1.0.
