VB.net图片放大缩小反转色彩实例，打开一张图片，可放大缩小图片，可将色彩反转，不知道是不是色彩反相，可看下截图所示的效果，另外还支持旋转图片，图片显示区域的窗口可以拉伸放大，这是VB.NET源码，了解一下图像处理的原理。

可靠性基础知识，不言而喻是十分重要的。它决定着一个产品的质量。因此是每一个搞质量控制人士的必备知识。- The reliable elementary knowledge, is self-evident is extremely important. It is deciding a product quality. Therefore is each does the quality control public figure s necessary knowledge.

我们公司开发的这款EA激进模式月收益110%左右，最大回撤在48%左右，单量在月120（手）左右，稳健的模式月收益50%-60%左右，最大回撤在25%左右，月单量在100（手）左右，保守的模式月收益20%-30%左右，最大的回撤10%左右，月刷单单量50-60（手）左右，基于刷单和盈利于一体。(Our company develops this EA radical model with a monthly return of about 110%, a maximum withdrawal of about 48%, a single volume of about 120 (hands) on January, a robust model with a monthly return of about 50% - 60%, a maximum withdrawal of about 25%, a monthly single volume of about 100 (hands), a conservative model with a monthly return of about 20% - 30%, a maximum withdrawal of about 10%, and a monthly brush. Single volume 50-60 (hand), based on brushing orders and profit in one.)

发射部分采用锁相环式频率合成器技术， MC145152和MC12022芯片组成锁相环，将载波频率精确锁定在35MHz，输出载波的稳定度达到4×10-5，准确度达到3×10-5，由变容二极管V149和集成压控振荡器芯片MC1648实现对载波的调频调制；末级功放选用三极管2SC1970，使其工作在丙类放大状态，提高了放大器的效率，输出功率达到设计要求。-Part of the launch phase-locked loop frequency synthesizer using technology, MC145152 and MC12022 PLL chips to lock in the exact carrier frequency 35MHz, the output carrier to achieve the stability of 4 × 10-5, reaching the accuracy of 3 × 10-5 by the varactor diode V149 and integration to achieve MC1648 chip VCO FM modulation on the carrier selection transistor amplifier at the end of class 2SC1970, to work in the C state to enlarge and improve the efficiency of the amplifier output power to meet the design requirements.
