使位图显示有阴影效果

类似Windows画图板的小程序 功能和界面全部模仿于Windows自带的画图板，功能主要有： 手绘线、简单图形、文字输入、图块拖放、重复撤销、画面缩放、打开保存图片文件，另外为了直接从数据库或者XML中存取图片，另外还提供了从Base64编码存取图片的接口，其他还实现了和画图板同样效果的工具箱及颜料盒。-Similar to Windows Paint program features small plates and interfaces in Windows, bringing all to imitate the drawing board, features mainly include: hand-painted lines, simple graphics, text input, drag and drop block, repeated withdrawal, screen zoom, open the save image file, In addition to directly from the database or XML access pictures, also provides access to images from the Base64 encoding of the interface, the other also achieved the same effect and drawing board of the toolbox and the color cartridge.

DIB（设备无关位图）的快速旋转方法，直接操作位图数据，分别对单色、16色、256色及24位位图进行单独处理-DIB (Device Independent Bitmap) rapid rotation method, the direct operation of bitmap data, respectively, for monochrome, 16 colors, 256 colors and 24 separate bitmap handle

GDI内存泄漏捕捉工具。该工具可以步骤EXE程序中使用GDI绘制时候内存泄漏代码捕捉。-GDI Memory Leak capture tool. The tool can be used in steps EXE program GDI memory leak when rendering code capture.

本人依据一篇文献介绍的方法编的彩色图像边缘检测程序，其效果要由于一般的方法。-literature on the basis of a methodology for the Color Edge Detection procedures, the effect due to the general approach.

VC_图像小波分解，包括图像处理算法，如小波算法等。-VC_ wavelet decomposition images, including image-processing algorithms, such as wavelet algorithm.

Hough变换用来在图象中查找直线。它的原理是：假设有一条与原点距离为s，方向角为θ的一条直线，直线上的每一点都满足方程 s=x*Cosθ+y*Sinθ，利用这个事实，我们可以找出某条直线来。这段程序，用来找出图象中最长的直线。-Hough Transformation is used for searching lines in an image . Here is the principle: Assume there is a line whoes direction is "sita" , and the distance from the origin to this line is s. So each point in this line satisfies the equation : s=x*Cos(sita)+ y*Sin(sita) . We can find out the lines based on this fact. And this programme is to find out the longest line in the image.

最近在做一个图片查看器，由于使用一般的PctureBox，在性能和缩放控制上都无法满足预期的要求，因此所有组件的呈现均是通过重写控件的OnPaint事件来绘制。在查看gif图片时发现Graphics.DrawImage只呈现第一帧，无法满足预期要求，因此经过摸索寻找到了解决自绘gif的较好办法。-At a recent picture viewer, because of the use of general PctureBox, at performance and zoom control are unable to meet expectations, all components are a rewrite control through case OnPaint to draw. Gif picture in view Graphics.DrawImage found only show the first frame, unable to meet expected requirements, therefore, after groping to find a solution since the better way to draw gif.
