Creates a LinearGradientBrush object from a set of boundary points and boundary colors
#include <GDIPlus.au3>
_GDIPlus_LineBrushCreate ( $nX1, $nY1, $nX2, $nY2, $iARGBClr1, $iARGBClr2 [, $iWrapMode = 0] )
| $nX1 | X coordinate of the starting point of the gradient. The starting boundary line passes through the |
| $nY1 | Y coordinate of the starting point of the gradient. The starting boundary line passes through the |
| $nX2 | X coordinate of the ending point of the gradient. The ending boundary line passes through the |
| $nY2 | Y coordinate of the ending point of the gradient. The ending boundary line passes through the |
| $iARGBClr1 | Alpha, Red, Green and Blue components of the starting color of the line |
| $iARGBClr2 | Alpha, Red, Green and Blue components of the ending color of the line |
| $iWrapMode | [optional] Wrap mode that specifies how areas filled with the brush are tiled: 0 - Tiling without flipping 1 - Tiles are flipped horizontally as you move from one tile to the next in a row 2 - Tiles are flipped vertically as you move from one tile to the next in a column 3 - Tiles are flipped horizontally as you move along a row and flipped vertically as you move along a column 4 - No tiling takes place |
| Success: | a pointer to a new LinearGradientBrush object. |
| Failure: | 0 and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
After you are done with the object, call _GDIPlus_BrushDispose() to release the object resources.
