Get image dimensions from command line

[rdnkjdi]

I'm looking for an easy way to get tif\jpg dimensions from a command line. You'd kinda think that if you can get it from Windows you could get it from a command prompt, but anyways...

I'm working with irfanview, and I'm trying to figure out a way to return dimensions to a text file. I found the /info command, and I can write the data to a textfile. Now I'm trying to find out if there is a way to

A.) Do all of the images in all of the subdirectories of a selected directory. (IE dir /s)
B.) Get JUST the dimensions, not all the other stuff.

Any help is greatly appreciated...it amazes me that I've been surfing the net for a half hour, and not found a good command line utility for getting image dimensions...

You can find a complete list of the command options plus examples here :

A) I don't think subdirs could be called too in one line. Maybe this can be solved by writing a batch-file.
A tutorial of this can be found here :

B) But I guess you also want the filename according to it. So far, i'm afraid that you have to edit that txt-file afterwards.
But with a proper ascii-editor you could clean up the lines quite smoothly, with a find-replace tool or with RegEx functions.

Thank you for the help...I think I'm on the right track. I do have one more question, is there any way to get irfanview to append to a text file instead of overwriting it?

I'm not sure if i understand your question correctly.
IV can open txt files, but of course only can save them as a bitmap.

Install ImageMagick (www.imagemagick.org). You get several utilities - "identify" is one of them.
Usage example:
>identify -format "%f %w %h" *.tif
ev01_40.tif 8731 8732
ev01_41.tif 8674 8648
ev01_42.tif 8730 8722

Here’s your help; use a batch script like the following (you must configure – see ”Configuration” block – this script before running it):

@echo off
cls
setlocal

:: --- Configuration --->

:: Temp-/Infofile path/name
set info=%temp%\info.txt

:: Dimension file path/name
set dims=C:\My Pictures\dimensions.txt

:: IrfanView
set iview=C:\IrfanView\i_view32.exe

:: File extensions
set filext=*.jpg *.tif

:: <--- Configuration ---

for /r %1 %%a in (%filext%) do call :EXTRACT "%%a"
goto :END

:EXTRACT
"%iview%" %1 /info="%info%"

for /f "tokens=4,6" %%a in ('type %info% ^| find.exe /i "Image dimensions"') do (set /a width=%%a) & (set /a height=%%b)

echo File: %~1 >> "%dims%"
echo Width: %width% Pixel >> "%dims%"
echo Height: %height% Pixel >> "%dims%"
echo. >> "%dims%"

goto :EOF

:END
if exist %info% del %info%

endlocal

Save this code, for example, as ”dim.cmd” and run it as:

"C:\My Scripts\dim.cmd" "C:\My Pictures"
