[英]How to run IDL procedure to perform Band Math on all band?
I tried to work with images using IDL Band Math.我尝试使用 IDL Band Math 处理图像。 The images have 90 bands and set variable pos=[0,1...90,] ,but only get one band(band1) into last.tiff图像有 90 个波段并设置变量pos=[0,1...90,] ,但只有一个波段(band1)进入last.tiff
PRO bandmath
compile_opt IDL2
e = envi()
Path = FILE_DIRNAME(ROUTINE_FILEPATH())+PATH_SEP()
print, Path
radiance_file = FILEPATH('QUAC.dat', $
root_dir=Path)
raster = e.OpenRaster(radiance_file)
print, raster
fid = ENVIRasterToFID(raster)
exp = '(b1 le 0)*0+(b1 gt 0)*(b1*0.0001)'
ENVI_File_Query, fid, DIMS=dims, NB=nb
pos = lindgen(nb)
print, pos
out_name = "last.tiff"
ENVI_DOIT, 'MATH_DOIT', DIMS = dims, FID = fid, $
POS = pos, EXP = exp, OUT_NAME = out_name, R_FID = r_fid
END
you can find api named ' CF_DOIT ' from envi claasic help您可以从 envi claasic 帮助中找到名为“ CF_DOIT ”的 api
