ENVI+IDL_将dat数据转化为tif格式

pro dat_to_tif
  envi = ENVI()

  dat_dir = 'F:\2020\raduation\1月\'
  tif_dir = 'F:\2020\raduation\1月\test\'

  file=file_search(dat_dir,'*dat',count = num)    ;dat文件个数存储到变量num中

  for i=0, num-1 do begin                     ;遍历所有dat文件
    raster = envi.OpenRaster(file[i])

    dat_filename = strsplit(file[i], '\' ,/EXTRACT)
    dat_filename = dat_filename[-1]
    dat_filename = strsplit(dat_filename, '.' ,/EXTRACT)
