<X1>: entier
X coordinate (in pixels) of top left corner of rectangle.
<Y1>: entier
Y coordinate (in pixels) of top left corner of rectangle.

<Start color>: Integer or constant
Start color of gradient. This color can correspond to:
<End color>: Integer or constant
End color of gradient. This color can correspond to:
<Angle>: Optional integer

Remarks

Gradient parameters

The color parameters are used as follows:
The angle is used to define the orientation of the gradient.
Gradients with 3 or 4 colors are only available for 0 or 90 degree angles.
Remark: The gradient colors are not available for some systems (Windows 98 or Me for example) or for TSE 256 colors. In this case, a rectangle whose color corresponds to <Start color> is displayed.
