    • Various technologies and techniques are disclosed that improve text rendering contrast. The shape of one or more characters is converted from an original format, such as a vector format received from a font, to an overscaled bitmap format. The width of the shape of the character is adjusted based on a text contrast setting. For example, the width of the shape can be adjusted by extending a right or other edge of the shape by the number of pixels corresponding to the numerical value of the text contrast setting. The shape is made wider or thinner based on the text contrast setting. A filtering procedure is used to determine density values for how the shape corresponds to a set of screen pixels. The density values are blended with color values related to the display device to form a modified shape ready for output. The modified shape is then displayed.
    • 公开了改善文本呈现对比度的各种技术和技术。 一个或多个字符的形状从原始格式(例如从字体接收的向量格式)转换为过大的位图格式。 基于文本对比度设置调整字符的形状宽度。 例如,可以通过将形状的右边缘或其他边缘延伸与对应于文本对比度设置的数值的像素数量来调节形状的宽度。 基于文本对比度设置,形状变得更宽或更薄。 滤波过程用于确定形状对应于一组屏幕像素的密度值。 将浓度值与与显示装置相关的颜色值混合以形成准备输出的修改形状。 然后显示修改后的形状。
