最近刚学GDI+,就想找个应用练练手,于是基于GDI+封装了此类,接口已经独立出来,使用十分方便,在MFC上直接使用(在VS2010 x64上编译,32位也可以),类的特定如下: 1.基于GDI+封装的类,文档和对话框可直接使用; 2.类初始化时可选择图片是否充满控件,充满的话,图片会适应控件的宽度进行缩放,但会保存原有的长宽比不变; 3.变换前后的坐标关系已经封装好,可直接调用; 4.缩放前后采样最临近点差值(windows图片查看器和PS都是采样这种差值方式,可能是因为效率比较高),具体差值方式可更改,参考一下GDI+就可以,如果想对图像像素进行操作,可使用GDI+的Bitmap类,可对图像像素点进行操作
