Initializes the m_AutoBrush member with a brush style according to the key value
See the How automatic colors and fills are chosen topic for details
Defined in: SRGComp.cpp
Return Value
Success or failure reported by the CBrush::CreateSolidBrush(..) or CBrush::CreateHatchBrush(..) function
Parameters
key
Key value
nColorRange
The color range. New to v 1.3. Set a range of 16 to use the standard color system. Other values will divide the spectrum by the color range and extract a suitable color from the key value. The color range works best when it is expressed as a binary number with only one bit set. (ie 32, 64, 128 etc) but this is not absolutely necessary.
