Creates a LinearGradientBrush object from a rectangle and boundary colors
#include <GDIPlus.au3>
_GDIPlus_LineBrushCreateFromRect ( $tRECTF, $iARGBClr1, $iARGBClr2 [, $iGradientMode = 0 [, $iWrapMode = 0]] )
| $tRECTF | $tagGDIPRECTF that specifies the starting and ending points of the gradient |
| $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 |
| $iGradientMode | [optional] The direction of the gradient: 0 - Horizontal direction from the left of the display to the right of the display 1 - Vertical direction from the top of the display to the bottom of the display 2 - Forward diagonal direction from the upper-left corner to the lower-right corner of the display 3 - Backward diagonal direction from the upper-right corner to the lower-left corner of the display |
| $iWrapMode | [optional] Specifies how areas filled with the brush are tiled: 0 - Tiling without flipping 1 - Tiles are flipped horizontally as you move from one tile to the next in a row 2 - Tiles are flipped vertically as you move from one tile to the next in a column 3 - Tiles are flipped horizontally as you move along a row and flipped vertically as you move along a column 4 - No tiling takes place |
| Success: | a pointer to a new LinearGradientBrush object. |
| Failure: | 0 and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
After you are done with the object, call _GDIPlus_BrushDispose() to release the object resources.
