图形(Graph)和图像(Image)都是多媒体系统中的可视元素,虽然它们很难区分,但确实不是一回事。图形是矢量图(Vector Drawn),它是根据几何特性来绘制的。图形的元素是一些点、直线、弧线等。图像是位图(Bitmap),它所包含的信息是用像素来度量的。
Paint.NET是一个图像和照片处理软件,它由华盛顿州立大学的学生开发和维护并由微软公司提供项目指导,早期定位于MS Paint的免费替代软件,现在逐渐发展为一个功能强大且易用的的图像和照片处理软件,支持图层,无限制的历史记录,特效,和许多实用工具,并且开放源代码和完全免费,界面看起来有点像Photoshop.该软件的开发语言是C#.

Paint.NET 3.5.3 Final
Fixed DirectDraw Surface (.dds) file format support for CPUs which do not have SSE2 (Pentium III, Athlon XP).
Fixed an issue with the File->Save dialog related to file type plugins that were only written for opening (importing).
Fixed some crashes which were supposed to be "out of memory" errors.
Fixed a race condition with the New Image, Canvas Size, and Resize dialogs. If you typed extremely fast you could cause a crash by typing a negative number and immediately divssing OK or Enter.
Fixed a File->Save dialog issue in Win7/Vista where it could ask you about overwriting the wrong file.

* Fixed incorrect window repainting in Windows XP, and in Vista/Win7 when Aero/DWM is turned off
矢量图常用于框架结构的图形处理,应用非常广泛。图形是人们根据客观事物制作生成的,它不是客观存在的;图像是可以直接通过照相、扫描、摄像得到,也可以通过绘制得到。
