计算机图形学基础， 绘制基本3D界面。

我做的矢量图形系统！！ -I do vector graphics system! !

通过BRESENHAM判定算法,绘制指定端点的直线,用来测试tuborC的图形编程-Determined through the Bresenham algorithm, draw a straight line designated endpoint, used to test tuborC graphical programming

用户自定义填充，通过图像刷子的机制实现。可用于地质岩性符号填充等多种用途。-user-defined filled through images of the brush mechanism to achieve. Geological lithology can be used to fill in the blanks symbols multiple uses.

类似画图板的小程序,仿MSAPINT界面,实现其大部分功能-Similar to a small drawing board procedures, imitation MSAPINT interface, realize most of its functions

其实颜色直方图简单来说，就是统计图像中具有某一特定颜色的象素点数目而形成的各颜色的直方图表示，不同的直方图代表不同图片的特征-color histogram simple fact, it is statistical image with a specific color of the pixel number of points which are in the color histogram, different pictures representing different histogram feature

这是一个实现多区域跟踪的程序，分开图片的多个部分，并单独访问每个部分的的像素。-This is a multi-regional tracking procedures, a number of separate pictures, and visit every single part of the pixel.

Ruby开发，类似培养Python,比Python强大，tk小例子-Ruby development, a similar training Python, Python powerful, small examples tk

通过对图象一系列的操作来计算一个图象中三角形的面积.-Images through a series of operations to calculate an image in the triangle area.

To display bmp,JPG, other formats and convert to other formats and compression as well.

gd 是一个图形库。它允许你的代码快速画图，使用线，弧，文件，多颜色，从其他的图片剪切和粘贴，充满填充和编写一个PNG文件结果。-gd is a graph storehouse. It permits your code fast painting, the use line, the arc, the document, the multi- colors, cut from other pictures and glue, fill fill and compile a PNG document result.
