Python2 + eog > 複数の画像をeogで開く | overlay_image_171003_execとの組合わせ例

Last updated at 2017-10-05Posted at 2017-10-03

動作環境

Xeon E5-2620 v4 (8コア) x 2
32GB RAM
CentOS 6.8 (64bit)
openmpi-1.8.x86_64 とその-devel
mpich.x86_64 3.1-5.el6とその-devel
gcc version 4.4.7 (とgfortran)
NCAR Command Language Version 6.3.0
WRF v3.7.1を使用。
Python 2.6.6 (r266:84292, Aug 18 2016, 15:13:37) 
Python 3.6.0 on virtualenv
GNU bash, version 4.1.2(1)-release (x86_64-redhat-linux-gnu)

Pythonスクリプトから複数画像をeogで開く。

code

test_eog_files_171003.py

from __future__ import absolute_import
from __future__ import division
from __future__ import print_function
import subprocess as sb
import os
import time

# on Python 2.6.6
# coding rule: PEP8

IMG_CMD = "eog"


def debug_show_single_image(afile):
    # require wait to open each image in eog
    chkcmd = IMG_CMD + " " + afile
    print(chkcmd)
    sb.Popen(chkcmd.split())
    time.sleep(1)

alist = "gray.png", "blue.png", "red.png"

for elem in alist:
    debug_show_single_image(elem)

run

$python test_eog_files_171003.py

上記を実行すると3つのeogのウィンドウが開く。

waitを入れないと1つのeogウィンドウしか開かない。

使用例

composite_171003.py

from __future__ import absolute_import
from __future__ import division
from __future__ import print_function
import glob
import sys
import subprocess as sb
import os
import time

# v0.1 Oct. 03, 2017
#   - add debug_show_single_image()
#   - add invoke_script()
#   - add get_filename()
#   - add remove_symlinks()


def invoke_script(ascript):
    #scd: script directory
    scd = os.path.dirname(os.path.realpath(__file__))
    acmd = scd + "/" + ascript
    print(acmd)
    sb.call(acmd.split())


def debug_show_single_image(afile):
    # require wait to open each image in eog
    chkcmd="eog " + afile
    print(chkcmd)
    sb.Popen(chkcmd.split())
    time.sleep(1)


res = sorted(glob.glob("png*/*_06.png"), key=os.path.getmtime)
for elem in res:
    print(elem)
    full_len = len(elem)
    #print(full_len)

    wo_hh = elem[:full_len - 7]  # 7: to remove "_hh.png"
    print(wo_hh)

    acmd = "overlay_image_171003_exec "
    for postfix in "_24.png", "_18.png", "_12.png", "_06.png":
        debug_show_single_image(wo_hh + postfix)
        #
        acmd += wo_hh + postfix + " "
    acmd += "wrk.png"
    acmd += ""
    invoke_script(acmd)
    debug_show_single_image("wrk.png")

    sys.exit()  # debug

データを用意して実行すると、4つのeogウィンドウが開き、それらの合成のwrk.pngがeogで開く。
