Description
Sets the blend factors and the blend positions
of this linear gradient brush to create a custom blend.

Parameters
brush
[in] Pointer to the
LinearGradientBrush
object.
blend
[in] Pointer to an array of real numbers that
specify blend factors. Each number in the array specifies a percentage
of the ending color and should be in the range from 0.0 through 1.0.
positions
[in] Pointer to an array of real numbers that
specify blend positions. Each number in the array indicates a
percentage of the distance between the starting boundary and the ending
boundary and is in the range from 0.0 through 1.0, where 0.0 indicates
the starting boundary of the gradient and 1.0 indicates the ending
boundary. There must be at least two positions specified: the first
position, which is always 0.0f, and the last position, which is always
1.0f. Otherwise, the behavior is undefined. A blend position between
0.0 and 1.0 indicates a line, parallel to the boundary lines, that is a
certain fraction of the distance from the starting boundary to the
ending boundary. For example, a blend position of 0.7 indicates the
line that is 70 percent of the distance from the starting boundary to
the ending boundary. The color is constant on lines that are parallel
to the boundary lines.
count
[in] Integer that specifies the number of
elements in the blend array. This is the same as
the number of elements in the positions array. The
blend factor at a given array index corresponds to the blend position
at that same array index.
