47      <p>Sets the linear conversion for glyph colors used while drawing characters.</p><p>First linear transformation is performed on each R, G, B and A component of the color that the glyph has and then the character is drawn. Specifically, drawing uses the <CODE>color</CODE> yielded for each component by the following formula:</p><pre> color = glyph * ( <span class="argument">max</span> - <span class="argument">min</span> ) / 255 + <span class="argument">min</span></pre><p> Note: <CODE>glyph</CODE> is the color for each pixel of the glyph.</p><p>This setting is valid after the <CODE><a href="../../../nw/font/CharWriter/SetupGX.html">nw::font::CharWriter::SetupGX</a></CODE> function is called.</p></div>
