Help batch watermarking in windows

[Babu]

Ive been working at batch proportionally watermarking while preserving background png transparency for 6 hours before I came on here to grovel for help from you guys. I tried doing this in other software (IrfanView and XnConvert) and was unable to preserve the transparency of my png background images. I tried mogrify but couldnt get syntax in there right. Bonus points if the new image can be created in a subfolder and preserves the image.png filename.

Please, always provide your IM version and platform when asking questions, since syntax may differ.

Also provide your exact command line and your images, if possible.

This works fine for me on IM 6.9.10.33 Mac OSX Sierra. Here I mogrify one transparent image, logot.png and put the rose: IM internal image at the bottom right corner.

Code: Select all

mogrify -format png -gravity southeast -draw "image over 0,0 0,0 'rose:'" logot.png

See https://imagemagick.org/Usage/basics/#mogrify_compose

For all image in a folder. Create a new folder for the output. Then cd to the current folder with your images

Code: Select all

cd path_to/imagefolder
mogrify -format png -path path_to/newfolder -gravity southeast -draw "image over 0,0 0,0 'rose:'" *

supply your own path where I have path_to.

On windows use \ rather than /. Also your cd will be something else.
