For me , creating hair is simply a matter of trial and error , and playing with the following tools : dodge , burn , airbrush in color mode , smudge and , most importantly , the undo tool 对于我来说创作头发只是一件简单的试验和出错的事情，只是与以下工具玩耍的事情：减淡工具、加深工具、在颜色模式下的喷枪，当然还有模糊工具，它是最重要的，不能重来的工具。
With ccd digital camera and optical microscope , color printing micro - dot image rgb data information can be got , then adopt the digital image processing and pattern recognition techniques to recognize the color patterns of pixels in the micro - dot images , at the same time , the color separation and area coverage can be retrieved 分色系统借助ccd数码相机和光学显微镜等设备，获取彩色印品显微网点图像的rgb的色彩数据信息；而后采用数字图像处理和模式识别技术对网点图像中各像素进行颜色模式识别，最终得到各单色网点图像的分色结果以及各色网点面积率。
With ccd digital camera and optical microscope , dia carries out measurements directly within images and obtain its rgb information ; then recognizes the color pattern of each pixel in micro images ( i . e . rgb - cmyk ) ; at last color separating results and some parameters of dots of each color class , which can be used to adjust and control ink amounts of each ink zone of each color on printers Dia系统借助ccd数码相机和光学显微镜等设备直接进行像内检测，获取显微网点图像的rgb数据信息；而后采用数字图像处理和模式识别技术对网点图像中各像素进行颜色模式识别( rgb cmyk ) ；最终得到各色网点图像的分色结果以及各色网点面积率等网点参数，这些参数可用于印刷机上各色各墨区的供墨量调节与控制。
According to its uses , lcd panel can be classified into 9 categories such as communication , domestic electrical appliance , palm computer , transportation means , measuring apparatus , meters and instruments , stationery , entertainment facility and others . according to display methods , lcd panel can be divided into two types , i . e . positive and negative types . according to optical modes , lcd panel falls into four categories , namely , reflective , transmissive , transflective and holographic types 液晶显示屏lcd分类方式有多种，如：按产品用途，可分为通信工具家用电器掌上电脑交通工具计量器械仪器仪表文教器具游艺设施等类别按显示方式，可分为正性负性两类按光学模式，可分为反射型透射型半透半反型全息型等4类按lcd类别，可分为tn型htn型stn型fstn型按颜色模式，可分为黄绿灰黑白蓝等按观察方向，可分为3 6 9 12点钟及其它等。
