Mogrify not working on batch

Hey all!
I am trying to create a batch file that process all jpgs in multiple subdirectories of certain folder.
It looks like this:
Code: Select all
cd C:\codigo2\
for /r /d %%a in (*) do mogrify -fuzz 30% -trim "%%~a\*.jpg"
pause
for /r /d %%a in (*) do mogrify -resize 1000x5000 "%%~a\*.jpg"
for /r /d %%a in (*) do mogrify -gravity center -extent 1115x5000 "%%~a\*.jpg"
pause
if I use mogrify -trim, it works perfectly. But as soon as I try to add the -fuzz 30%, it throughts the following error:
The following usage of the path operator in batch-parameter substitution is invalid: %~a*.jpg"
Do you know how to tell windows I am trying to pass multiple parameters with hyphens?
This code works perfectly, is the added -fuzz 30% that breaks it.
Code: Select all
cd C:\codigo2\
for /r /d %%a in (*) do mogrify -trim "%%~a\*.jpg"
pause
for /r /d %%a in (*) do mogrify -resize 1000x5000 "%%~a\*.jpg"
for /r /d %%a in (*) do mogrify -gravity center -extent 1115x5000 "%%~a\*.jpg"
pause
I also tried this on cmd and work perfectly:
Code: Select all
mogrify -fuzz 30% -trim "image.jpg"
Best regards!

When using percent signs in a BAT script you must almost always double them. Your "-fuzz 30%" that works from the command prompt needs to be "-fuzz 30%%" in the script.

Here is a useful Powershell script the converts recursively. you can modify it to run any conversions or file processing.
If desired, you can run Mogrify instead of Convert.
Code: Select all
# Powershell script to recursively convert image formats
# Configuration
$srcfolder = "C:\test\Animals"
$destfolder = "C:\test\Animals"
#This ps1 file will add copy files to designated folder
#Do NOT use Mogrify or the original images will be deleted
$im_convert_exe = "convert.exe -density 300"
# with VECTOR files the density setting should come BEFORE the vector format
# is specified or the image will be blurry.
# for example - for vector files place -density option immediately after the convert.exe
# command in the im_convert_exe definition. This way it will be set before any
# vector format is specified.
# change src_filter to the format of the source files
$src_filter = "*.eps"
# change dest_ext to the format of the destination files
$dest_ext = "png"
$options = "-depth 8 -alpha off"
$logfile = "C:\temp\convert.log"
$fp = New-Item -ItemType file $logfile -force
$count=0
foreach ($srcitem in $(Get-ChildItem $srcfolder -include $src_filter -recurse))
{
$srcname = $srcitem.fullname
# Construct the filename and filepath for the output
$partial = $srcitem.FullName.Substring( $srcfolder.Length )
$destname = $destfolder + $partial
$destname= [System.IO.Path]::ChangeExtension( $destname , $dest_ext )
$destpath = [System.IO.Path]::GetDirectoryName( $destname )
# Create the destination path if it does not exist
if (-not (test-path $destpath))
{
New-Item $destpath -type directory | Out-Null
}
# Perform the conversion by calling an external tool
$cmdline = $im_convert_exe + " `"" + $srcname + "`"" + $options + " `"" + $destname + "`" "
#echo $cmdline
invoke-expression -command $cmdline
# Get information about the output file
$destitem = Get-item $destname
# Show and record information comparing the input and output files
$info = [string]::Format( "{0} `t {1} `t {2} `t {3} `t {4} `t {5}", $count,
$partial, $srcname, $destname, $srcitem.Length , $destitem.Length)
echo $info
Add-Content $fp $info
$count=$count+1
}
