面向PCB打印的区域填充算法

Filling Algorithm Research and Application Oriented PCB Print

提出了一种适用于Gerber光栅化的基于阈值的自适应填充算法。针对Gerber文件的高精度要求,将区域填充算法应用到PCB打印机中,并针对传统填充算法在Gerber光栅化中产生的错误对算法加以改进,使之成为更加适合于Gerber光栅化的填充算法,提高了光栅化图形的质量。实验结果表明:对比以往的算法,改进的算法更适合于Gerber文件的光栅化,具有速度快、效率高等优点,完全避免了填充的错误,有助于PCB印刷质量的提升。

The paper proposed threshold-based adaptive filling algorithm for Gerber rasterizing. Based on high-precision requirements of Gerber, the original filling algorithm is applied to the PCB printer. For the error produced in traditional algorithm, the new algorithm being improved is more suitable for Gerber. Experimental show that the new algorithm is faster and with high efficiency for Gerber rasterizing compared with original. It helps to enhance the quality of PCB printing and promote the PCB printing industry.
