本文介绍了使用Inkscape从批处理文件将SVG转换为PNG许多文件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个包含许多svg文件的文件夹,我想使用inkscape和批处理脚本(Windows 10 *.bat
文件)将它们转换为png文件.以下脚本对于单个文件正确运行,但是,如何对目录中的数百个文件重复相同的命令?
I have a folder containing many svg files and I would like to convert them to png files using inkscape with a batch script (Windows 10 *.bat
file).
the following script works correctly for a single file but, how to iterate the same command for hundreds of files inside a directory?
PATH = "C:\Program Files\Inkscape"
inkscape myfile.svg --export-png=myfile.png
推荐答案
@echo off
for %%i in ("%~dp0*.svg") do (
echo %%i to %%~ni.png
"C:\Program Files\Inkscape\bin\inkscape.com" --export-type="png" "%%i"
)
要通过利用所有逻辑内核来加快处理速度,可以使用以下多任务处理方法:
并行执行Shell进程
To speed things up by utilizing all of your logic cores, you can use this multitasking approach:
Parallel execution of shell processes
@echo off
setlocal enableDelayedExpansion
:: Define the command that will be run to obtain the list of files to process
set listCmd=dir /b /a-d "%~dp0*.svg"
:: Define the command to run for each file, where "%%F" is an iterated file name from the list
:: something like YOUR_COMMAND -in "%%F" -out "%%~nF.ext"
set runCmd=""C:\Program Files\Inkscape\bin\inkscape.com" --export-type="png" "%%F""
:: Define the maximum number of parallel processes to run.
set "maxProc=%NUMBER_OF_PROCESSORS%"
::---------------------------------------------------------------------------------
:: The remainder of the code should remain constant
::
:: Get a unique base lock name for this particular instantiation.
:: Incorporate a timestamp from WMIC if possible, but does not fail if
:: WMIC not available. Also incorporate a random number.
set "lock="
for /f "skip=1 delims=-+ " %%T in ('2^>nul wmic os get localdatetime') do (
set "lock=%%T"
goto :break
)
:break
set "lock=%temp%\lock%lock%_%random%_"
:: Initialize the counters
set /a "startCount=0, endCount=0"
:: Clear any existing end flags
for /l %%N in (1 1 %maxProc%) do set "endProc%%N="
:: Launch the commands in a loop
set launch=1
for /f "tokens=* delims=:" %%F in ('%listCmd%') do (
if !startCount! lss %maxProc% (
set /a "startCount+=1, nextProc=startCount"
) else (
call :wait
)
set cmd!nextProc!=%runCmd%
echo -------------------------------------------------------------------------------
echo !time! - proc!nextProc!: starting %runCmd%
2>nul del %lock%!nextProc!
%= Redirect the lock handle to the lock file. The CMD process will =%
%= maintain an exclusive lock on the lock file until the process ends. =%
start /b "" cmd /c >"%lock%!nextProc!" 2^>^&1 %runCmd%
)
set "launch="
:wait
:: Wait for procs to finish in a loop
:: If still launching then return as soon as a proc ends
:: else wait for all procs to finish
:: redirect stderr to null to suppress any error message if redirection
:: within the loop fails.
for /l %%N in (1 1 %startCount%) do 2>nul (
%= Redirect an unused file handle to the lock file. If the process is =%
%= still running then redirection will fail and the IF body will not run =%
if not defined endProc%%N if exist "%lock%%%N" 9>>"%lock%%%N" (
%= Made it inside the IF body so the process must have finished =%
echo ===============================================================================
echo !time! - proc%%N: finished !cmd%%N!
type "%lock%%%N"
if defined launch (
set nextProc=%%N
exit /b
)
set /a "endCount+=1, endProc%%N=1"
)
)
if %endCount% lss %startCount% (
timeout /t 1 /nobreak >nul
goto :wait
)
2>nul del %lock%*
echo ===============================================================================
