示例1: GetCachedLinearGradientBrush
private LinearGradientBrush GetCachedLinearGradientBrush(Color color1, Color color2)
{
long kh = color1.ToArgb(); // high bits
long kl = color2.ToArgb(); // low bits
var colorKey = (kh << 32) | kl;
LinearGradientBrush brush;
if (!m_linearGradients.TryGetValue(colorKey, out brush))
{
var stops = new GradientStop[2];
stops[0].Color = color1.ToColor4();
stops[0].Position = 0;
stops[1].Color = color2.ToColor4();
stops[1].Position = 1;
using (var stopCollection = new GradientStopCollection(m_renderTarget, stops, Gamma.StandardRgb, ExtendMode.Clamp))
{
var props = new LinearGradientBrushProperties();
brush = new LinearGradientBrush(m_renderTarget, props, stopCollection);
}
m_linearGradients.Add(colorKey, brush);
}
return brush;
