说明：  java颜色获取和调色源码，功能不是特别强，但是简单实用(java color palette to access and source, function is not particularly strong, but simple and practical)

有关绘图的非常有用的学习资料，用它学习matlab，从入门到精通，面面俱到(Drawing on the very useful learning materials, use it to learn matlab, from entry to the master, everything)

PSCAD中搭建的输电线路行波故障测距仿真模型，并仿真实现。(Transmission Line Traveling Wave Fault Location in PSCAD build simulation models and simulation.)

根据图框块自动识别图纸并预览打印。函数参数分别为：打印机名称，打印样式，打印纸张，打印份数，自动纸张，自动旋转，自动关闭，自动识别图框(Autoprint according to the drawing blocks.)

二维绘图，包括直线，矩形，圆，多边形等绘制(Two-dimensional graphics, including lines, rectangles, circles, polygons drawn)

信号频谱分析 1. 观测已知方波信号、正弦波信号的频谱 分析频率为4KHz、8KHz的占空比为50 的方波信号、正弦波信号的频谱。记录所得频谱图。 观测实时模拟信号（语音）的频谱 用音频设备采集一段语音，将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的，应把它分段分析，而且实际运用中的数字信号处理的FFT的点数是有限的，一般只能达到千点。用傅里叶反变换IFFT，从频域恢复信号。画出频谱图和语音波形图(Signal spectrum analysis 1. Observing a known square-wave signal, sine wave signal frequency spectrum analysis 4KHz, 8KHz for the 50 duty cycle square wave signal, sine wave signal frequency spectrum. The recorded frequency spectrum. Observing real-time analog signal (voice) of the spectrum collected with the audio devices section of voice, voice saved as. Wav format. Wav file of the sub-Fourier transform analysis to make. Speech is divided into syllables, it should be sub-analysis, and practical application of digital signal processing of the FFT points is limited, generally only reach 1000 points. Fourier inverse transform IFFT, to restore the signal from the frequency domain. Draw maps and voice waveform spectrum)

贝塞尔曲线绘制源码，例程程序调用API函数PolyBezier根据坐标点画贝塞尔曲线，或根据贝塞尔曲线特点在画板上画直线连接各坐标点。(Bezier curve drawing source , routine program calls API function PolyBezier Bezier curve based on the coordinates stippling , or draw a straight line on the drawing board in accordance with the characteristics of the Bezier curve connecting the coordinate points .)

The figure used to draw the feedback on a layout.

单文档绘图工具，包括直线，曲线，扇形，圆形，圆角矩形，矩形等图形，还可以设置线条的颜色等属性。(Single document drawing tools including lines, curves, fan-shaped, round, rounded rectangle, rectangle and other graphics, you can also set the line color and other attributes.)
