Script per automatizzare il lavoro di VRIMG2EXR

Sono di fretta ma posto questo script che ho fatto in python per estrarre in un colpo solo tutti i canali da un file VRIMG. Per ora è lanciato tramite un batch perchè non sono ferratissimo in python e avevo necessità di farlo funzionare, sono aperto a qualunque miglioramento :)

Funziona da interfaccia per vrimg2exr.exe, ora sono proprio di corsa ma posto il codice perchè lo sto usando in questo momento e lavora da dio.

vrconv.bat:

@echo off

rem VRCONV: automatize vrimg conversion to exr,

rem finding all channels and separing them

rem -------- (C) 2011 Pietro Grandi -----------

rem Put here your ../vrimg2exr.exe complete path to find it

set VRAY2EXR=vrimg2exr.exe

rem Requiring info

%VRAY2EXR% -info %1 > %1.INFO.txt

if errorlevel 1 (goto:error)

rem Generate info file

set VRCONV_FILE=%1.INFO.txt

echo cmd: File has been saved as %VRCONV_FILE%

python vrconv.py %VRCONV_FILE%

goto:eof

:error

echo Some error occurred with %VRAY2EXR%

v_channels=[()]

index=current.find('"')

v_channels.append(current[index:rev_index])

k+=1

current=f.readline()

print("{0}: {1} channels found. Extracting...".format(name, k-1))

filename_vrimg=v_channels[1].strip('"')

filename_basic=filename_vrimg.strip('vrimg')

for i in range(2,k) :

print("{0}: Working on {1} channel".format(name,v_channels[i]))

os.system(vrimg2exr+" "+filename_vrimg+" "+"-channel "+v_channels[i])

filename_new=filename_basic+v_channels[i].strip('"')+".exr"

print("{0}: {1} is now {2}".format(name,filename_basic+"exr",filename_new))

os.rename((filename_basic+"exr"),filename_new)
