VB声明：

Declare Function GdipDrawImageRect(Graphics As Long, Image As Long, X As Single, Y As Single, Width As Single, Height As Single) As GpStatus

函数说明：向Graphics对象输出Image

参数：

Graphics：Graphics对象，可调用GdipCreateFromHDC函数创建

image：image对象，可由GdipLoadImageFromFile加载的图像文件

X：显示起始位置X坐标，对应图像的左上角

Y：显示起始位置Y坐标，对应图像的左上角

Width：图像宽度，可调用GdipGetImageWidth函数获取图像实际宽度赋值

Height：图像高度，可调用GdipGetImageHeight函数获取图像实际高度赋值

返回值：GpStatus类型值

说明：Width、Height假如等于图片的实际尺寸，那图片将按原大小显示，否则将按新尺寸进行缩放。

该方法被重载，可参阅：GdipDrawImage、GdipDrawImageI、GdipDrawImagePointRect、GdipDrawImagePointRectI、GdipDrawImagePoints、GdipDrawImagePointsI、GdipDrawImagePointsRectI、GdipDrawImageRectI、GdipDrawImageRectRect、GdipDrawImageRectRectI

备注：.net平台封装了该方法在Graphics类中
