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); } } 以上就是本文的全部内容,希望本文的内容对大家的学习或者工作能带来一定的帮助,同时也希望多多支持编程小技巧!
