smooth graphics scaling, and the proportion, quite good!

在Delphi环境下调用AutoCad，并增加相应模块，能在Cad中进行维作图-In the Delphi environment called AutoCad, and add the corresponding module can be carried out in the Cad-dimensional mapping

为了将零件固定在PCB上面，我们将它们的接脚直接焊在布线上。在最基本的PCB（单面板）上，零件都集中在其中一面，导线则都集中在另一面。这么一来我们就需要在板子上打洞，这样接脚才能穿过板子到另一面，所以零件的接脚是焊在另一面上的。因为如此，PCB的正反面分别被称为零件面（Component Side）与焊接面（Solder Side）。-parts to be fixed above the PCB, we will take their feet welded directly on the wiring. At its most basic PCB (single-panel), parts of which are concentrated in the side, wire were concentrated on the other side. Suppose we need burrows on the board, then through the legs of another plank, then parts of the legs is another welding in the face. Because of this, the PCB is negative components were known as surface (Component Side) and the welding surface (Solder Side).

输入半径及等分点数便可画出相应的圆并且将等分点两两相连（供初学者参考）-radius and the importation of sub-division will draw the corresponding circle will be broken down and on February 2 points connected (for advanced users)

本程序实现了直线（Bresenham算法和DDA算法），和圆（中点Bresenham算法和正负法）的绘制，并能够选取其颜色。-This procedure has a straight line (Bresenham algorithm and DDA algorithm) and round (mid-point of Bresenham algorithm and plus or minus method) drawing, and be able to select the color.

用turboC实现的16位dos下的高色彩显示程序，想学学底层图形模式的朋友可以来看看。主要是中断的使用。-used to achieve the 16 dos, the high color display program, would like to learn the underlying graphics mode can be a friend to look at. The main use is broken.

应用背景图像正交变换  ， 傅立叶变换优化，在对图像进行傅里叶变换变换是复杂度为O(n^2)，当n很大时 此算法可以优化关键技术采用FFT和IFFT进行傅立叶变换 ，大大缩减运行时间 节约系统资源 傅立叶定理 卷积定理

图像颜色处理效果-color image processing results

用一种简单的分块算法对10个数字进行了有效的识别-use of a simple algorithm to block 10 figures for the effective recognition

本文实现了将自定义的文本或者图形保存到位图bmp文件。提供源代码下载。 我们在用vc做程序时候，经常需要把输出的文本和图形保存到位图文件，当然可以有现成的控件来实现,但总不能如自己所愿 -This article will realize a custom text or graphics in place plans to preserve bmp file. Provide the source code download. We have to do with vc procedures often need to output text and graphics document preservation plan in place, of course, can have ready-made controls to achieve, but should not, such as their wish
