本文主要介绍了利用IRawPixels接口遍历栅格数据。具有很好的参考价值，下面跟着小编一起来看下吧
AO的版本为10.2，开发的语言是C#。栅格数据来源IRasterDataset接口。
IRasterBandCollection pRasterBandCollection = pRasterDataset as IRasterBandCollection;
IRasterBand pRasterBand = pRasterBandCollection.Item(0);
IRaster pRaster = (pRasterDataset as IRasterDataset2).CreateFullRaster();
IRawPixels pRawPixels = pRasterBand as IRawPixels;
IRasterProps pRasterProps = pRasterBand as IRasterProps;
int dHeight = pRasterProps.Height;
int dWidth = pRasterProps.Width;
IPnt pntSize = new PntClass();
pntSize.SetCoords(dHeight, dWidth);
IPnt pPixelBlockOrigin = new PntClass();
pPixelBlockOrigin.SetCoords(0, 0);
IPixelBlock pixelBlock = pRaster.CreatePixelBlock(pntSize);
pRawPixels.Read(pPixelBlockOrigin, pixelBlock);
System.Array arr = (System.Array)(pixelBlock as IPixelBlock3).get_PixelData(0);
for (int i = 0; i < dHeight;i++ )
{
for (int j = 0; j < dWidth; j++)
{
float number = 0;
float.TryParse(arr.GetValue(i,j).ToString(),out number);
}
