python 利用 PIL 将数组值转成图片的实现

pip install pillow

from PIL import Image
arr=numpy.asarray([[1,2,3,4,5],[2,3,4,5,6],[7,8,9,0,12]])
image = Image.fromarray(arr).convert("L")# L为模式
image.save("out.jpg")#输出图片格式可以自己选择

from PIL import Image

a=numpy.asarray([[1,2,3,4,5],[2,3,4,5,6],[7,8,9,0,12]])
b=numpy.asarray([[1,2,3,4,5],[2,3,4,5,6],[7,8,9,0,12]])
c=numpy.asarray([[1,2,3,4,5],[2,3,4,5,6],[7,8,9,0,12]])

r = Image.fromarray(a).convert('L')
g = Image.fromarray(b).convert('L')
b = Image.fromarray(c).convert('L')

image = Image.merge('RGB',(r,g,b))
image.save("out.jpg")

conda install h5py

import h5py
openFileName = h5py.File(fileName)
EASE_column_index_1km=openFileName['Soil_Moisture_Retrieval_Data_1km'['EASE_column_index_1km'][:]#得到Dataset的数据
b=openFileName['a']['rangeEndingDateTime'].value#得到rangeEndingDateTime里面的文本值

conda install -c conda-forge pyhdf 

from pyhdf.SD import SD, SDC
openFileName = SD(filename, SDC.READ)
a = j.select('Night_view_angl')[:]#获得Night_view_angl  Dataset的值
