Dear list,

I am a brand new ImageMagick user (working in Windows 7) so forgive my ignorance but I would like to recurse this command to convert the background of a png to transparent, overwriting the original files (rather than copying to a new folder)

Code: Select all

FOR %G IN (*.png) DO convert %G -transparent white test \%G

By following the thread here viewtopic.php?f=1&t=14112&start=15 and example here
I put together this command

Code: Select all

FOR /R %%a IN (*.png) DO convert -transparent white "%%~a" "%%~dpna.png

getting this error

Code: Select all

%%a was unexpected at this time.

Altering to:

Code: Select all

for /R %i IN (*.png) DO convert -transparent white "%i" "%%~dpna.png"

(based on another batch script I have) runs but does not overwrite the output to the original files instead to a png named %~dpna in the top folder
If anyone has a moment to help me tweak the code I would really appreciate the advice!

Thanks for reading
Rebecca

If you are typing at the command line, don't double percent characters.

If you are running BAT files, do double percent characters.

Your last command sets up variable %i but uses both %i and %a.
