　GDI+的应用使得平面图形图象编程变的更加容易，本文以一个基于对话框的时钟程序为例，在VC6.0中调用*.png图片实现半透明渐变窗口，该程序实现了指针式和数字式两种时钟显示方式。窗口实现了半透明渐变窗口、窗口拖动无移动矩形框、隐藏了任务栏窗体按钮等。-GDI+ application programming makes the plane graphic images become easier, this paper, a dialog-based clock program as an example, VC6.0 call*. png image to achieve gradient translucent window, the program achieved a pointer two kinds of clocks and digital display. Achieved a translucent window, gradient window, drag the window without moving a rectangular box, hide the taskbar buttons and so on form.

用递归的方法进行连通域的标记，算出面积并且去除小面积的连通域，对于去噪很有效！-Using recursive methods of tags connected domain, calculate the area and remove a small area connected domain for denoising very effective!

计算机图形学初级学者（教科书画法）中点画圆算法-computer graphics beginner (textbook method), the algrithm of middle point circle-drawing.

识别数字的源代码-identification number of source code

一个用MFC开发的画圆程序，简单实用，可作为编程爱好者的参考。-a development with MFC Circle procedures simple and practical, can be used as a reference programming enthusiasts.

该代码可以通过GDAL处理大数据图像，可以读取多种数据格式，可广泛应用于遥感图像处理，可供大家参考。

CRT显示器上又rgb值计算xyz值程序，gog模型是目前最广泛使用的CRT显示器模型-CRT monitors also xyz values rgb value procedures, gog model is the most widely used model of CRT monitors

This is a plugin script for Go-ogle"s free 3D design program Sketchup. The free version of Sketchup has limited file export options and many CAM programs will not recognise the native Sketchup (SKP) file format. This plugin allows you to export your Sketchup model as a DXF or STL files readable by most CAM and 3D printer software.Using the pluginAfter copying this file, start Sketchup and you should now have an extra menu option (Export to DXF or STL) in the Sketchup Tools menu.There are five export options:STL  triangles. Use this for Makerbot or Reprap style 3D printersDXF polyface mesh. This will give the most faithful reproduction of your original Sketchup model.DXF polylines: exports the outlines of each face as a polyline, sometimes useful for CAM toolpaths.DXF triangular mesh: breaks all the faces up into trianglesDXF lines. This
