示例1: Init

m.ctxt = ctxt
m.kc = ctxt.KeyboardChan()
m.screen = ctxt.Screen()
m.dx = m.screen.Width()
m.dy = m.screen.Height()
m.colorModel = m.screen.ColorModel()
m.pix = make([][]uint8, m.dy)
for i := range m.pix {
m.pix[i] = make([]uint8, m.dx)
}
m.cmap = make([]image.Color, 256)
for i := range m.cmap {
var r, g, b uint8
r = uint8(min(0, 255))
g = uint8(min(i*2, 255))
b = uint8(min(0, 255))
m.cmap[i] = m.colorModel.Convert(image.RGBAColor{r, g, b, 0xff})
}
