摘要
作者因需要用ＭａｃｒｏｓｏｆｔＣ５．０设计了一个拷贝屏幕图形的内存驻留程序。该程序利用半色调技术实现了按不同比例、不同灰度把ＴＶＧＡ显示器上绘制的图形（１２０×７６８，１６色）部分或全部从ＳｔａｒＡＲ３２４０打印机上输出拷贝。输出的图形清晰，且不失真。
As the authoe had to use Macrosoft C 5.0,a internal memory resident pro-gram was designed to copy screen image. In the peogram the semitoning technique was used to permit image(1024×786,16 colors)plotted on the TVGA display unit in varied propor-tions and gray levels to be printed partly or wholly from a Star AR3240 printer with a clearand distortionless printout.
