利用偏移量插值实现图像的透视变换（运用了双线性变换原理）-Offset interpolation using the image perspective transformation (using the bilinear transformation principle)

VB波形生成示例程序的源码文件，此程序包含了方波、三角波、正弦波等波形的绘制生成，还有随机长生折线波形和自定义绘制波形等等。 根据四个参数生成波形：振幅、周期、偏移量和需要生成的波形类型。-VB waveform generation sample program source code files, this program contains a square wave, draw triangle wave, sine wave generator, etc., as well as ran

产生四种波形，调整幅值、频率、波形的选择、相位、偏移参数-Produce four waveforms, adjust the amplitude, frequency, waveform selection, phase, offset parameters
