urge自用渐变字体
催更urge作者拿到了支持渐变字体的版本，拿 CP Gradient Text script 改一个自用的版本效果：
module GTU # Do not edit #
# #
# Chooses if the gradient colors are applied.Can be turned to false if you #
# just want to use the font buffer. #
GRADIENT = true # Default = true #
# #
# The bop and bottom shading of the font.A number between 0 and 100 should #
# be used.The top is changed to black while the bottom is changed to white.#
LIGHT = 70 # Default = 70 #
DARK = 40 # Default = 40
end
#~ 渐变使用方法：
#~ Font.default_gradient_color = Color.new(0, 0, 0, 125)
#~ 其中font.color为顶层颜色
#~ font.gradient_color为底层颜色，
#~ font.gradient_color.alpha属性决定渐变程度，
#~ 设置为0时则不使用渐变效果
class Bitmap## Alias draw_text for all the new functions.
alias gtu_draw_grad_text draw_text unless $@
def draw_text(*args)
if not GTU::GRADIENT
return gtu_draw_grad_text(*args)
end
dark = font_color_dark
dark.alpha = 255.0 * (1 - GTU::LIGHT / 100)
self.font.gradient_color = dark
res = gtu_draw_grad_text(*args)
self.font.gradient_color = Color.new(0, 0, 0, 0)
return res
end
def font_color_dark## Creates the dark font color.
r = font.color.red
g = font.color.green
b = font.color.blue
color = []
.each {|c| color.push(c - c * GTU::DARK / 100) }
return Color.new(color, color, color, font.color.alpha)
end
end
