Command Line Batch Resize and rename

[ckiley28]

I am currently trying to resize and rename a collection of jpgs using the following command line:

i_view32.exe c:\savers\jpg\*.jpg /resize=(800,600) /convert=c:\savers\bmp\PICT#.bmp

It converts the files like it should but keeps overwriting each other and I always end up with one file in C:\savers\bmp: "PICT#.bmp"

How do I get the "#" in "PICT#.bmp" to increment with each file it resizes?

Use a batch script like the following.


Example:

@echo off
cls
setlocal

:: --- Configuration --->

:: Path to IrfanView
set iview=E:\IrfanView\i_view32.exe

:: Source path
set source=H:\Meine Photos\jpg

:: Target path
set target=H:\Meine Photos\bmp

:: File name
set prefix=PICT

:: Suffix of the source files
set ssuffix=jpg

:: Suffix of the target files
set tsuffix=bmp

:: Start index of the counter
set index=1

:: Addition value of the counter
set step=1

:: Leading zeros of the counter (delete value for no leading zeros)
set zeros=000

:: <--- Configuration ---

for %%a in ("%source%\*.%ssuffix%") do call :CONVERT "%%a"
goto ENDE

:CONVERT
set number=%zeros%%index%
set number=%number:~-4%
echo %~1
"%iview%" %1 /resize=(200,100) /convert="%target%\%prefix%%number%.%tsuffix%"
set /a index=%index% + %step%
goto :EOF

:ENDE

endlocal

AFAIK Irfanview cannot put an incrementing count into the file name using a simple, single command line such as this. You do need to use a batch script such as the one Foxy has posted to generate the number for you. The usual way of using the * option in the input filename is to put one in the output filename too e.g /convert=c:\savers\bmp\*.bmp
Each output file will then have the same name as the input one but with a .bmp suffix instead of .jpg
The nearest you can get to a count is to put a placeholder for the index number of the input file into the pattern e.g /convert=c:\savers\bmp\PICT$X.bmp
That will give you output filenames such as ...., PICT[2_30].bmp , PICT[3_30].bmp , .... etc.

I assume that there is some reason for not opening Irfanview and using the built in Batch Conversion and Rename feature. That can rename with an incrementing count number in the filename.

Foxy,

That is exactly what I needed. Thank you very much!!!!

Mij - I am trying to automate a process like you said.

Thanks for the feedback guys!
