Batch watermark problem

[acrocephalus]

Hello!
I'm trying to batch watermark a full directory of jpg images using this code:

Code: Select all

composite -gravity SouthEast -geometry +10+10 stamp.png *.jpg

but it does not work. In fact, it replaces the last image with the first (which it is watermarked!) Any idea on how to solve it?
Cheers!

Convert and composite do not allow working on a directory of images. see mogrify. But I am not sure mogrify will allow the composite. If not, then you likely will need to write a script to loop over your images.

If you're using Windows, you can use this statement in a DOS window to process all JPG in a directory:

Code: Select all

for %F in (*.jpg) do composite -gravity SouthEast -geometry +10+10 stamp.png %F %F

If you want to do this in a batch file you must double the percent signs:

Code: Select all

for %%F in (*.jpg) do composite -gravity SouthEast -geometry +10+10 stamp.png %%F %%F
