Remarks

Gradient parameters

The color parameters are used as follows:
The angle is used to define the orientation of the gradient.
The gradients performed with 3 or 4 colors are only available for an angle set to 0 or 90 degrees.
Note: 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.
