GdipDrawImageRect
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
