在GDAL中以BSQ的形式保存GTiff文件

在GDAL中以BSQ的方式保存GTiff文件

GDAL保存GTiff文件时默认是以BIP的方式保存的，以BSQ方式保存的例程如下：

int main(int argc, char* argv[]){char* InputFileName="c:\\Cup95eff.tif";char* OutputFileName="c:\\TestOut.tif"; GDALAllRegister();         //利用GDAL读取图片，先要进行注册CPLSetConfigOption("GDAL_FILENAME_IS_UTF8","NO");   //设置支持中文//准备读取图片GDALDataset *ReadDataSet=(GDALDataset*)GDALOpen(InputFileName,GA_ReadOnly); int width=ReadDataSet->GetRasterXSize();  int height=ReadDataSet->GetRasterYSize();int count=ReadDataSet->GetRasterCount();float *pDataIn=new float[width*height*count];if(ReadDataSet->RasterIO(GF_Read,0,0,width,height,pDataIn,width,height,GDT_Float32,count,NULL,0,0,0)==CE_Failure )return -2;//准备保存图片 const char *pszFormat ="GTiff";GDALDriver *poDriver=GetGDALDriverManager()->GetDriverByName(pszFormat);if( poDriver == NULL ) return -1; char **papszOptions = NULL;papszOptions = CSLSetNameValue( papszOptions, "INTERLEAVE", "BAND" );GDALDataset *WriteDataSet = poDriver->Create(OutputFileName, width,height,count,GDT_Float32,papszOptions);if(WriteDataSet->RasterIO(GF_Write,0,0,width,height,pDataIn,width,height,GDT_Float32,count,NULL,0,0,0)==CE_Failure )return -3;//保存图像的相关信息//GetSetGDALDatasetMessage(ReadDataSet,WriteDataSet);delete ReadDataSet;ReadDataSet=NULL;delete WriteDataSet;WriteDataSet=NULL;delete[] pDataIn;pDataIn=NULL;return 0;}

关键是设置属性的这一句：

papszOptions = CSLSetNameValue( papszOptions, "INTERLEAVE", "BAND" );
