Using ImageMagic v6, the simplest approach to overlaying one image on another is to do a "-composite" operation something like this...

Code: Select all

convert photo.png logo.png -gravity southeast -geometry +10+10 -composite output.png

The "-gravity southeast" tells it to place the overlay in the bottom right corner. The "-geometry +10+10" tells it to move the overlay up from the bottom and over from the right by 10 pixels in each direction. There are many more settings available to accommodate almost any special requirements you might have. We'd need more details to give you better help.

Hello, thank you so much response. It 'the first time you use this library, usually I used gd but not having installed php on my PC (using linux) I needed something to terminal to automate the insertion of a logo on the images.

I'm finding out slowly imagemagick and I must say it is fantastic.

I tried your suggestion and it works great. One thing, it would be possible to apply the inclusion of "logo.png" in all the photos in this directory?

There are many, like 100, it would be possible to add it at all? thank you so much.

What is your IM version and platform. Please alway provide that since syntax and approach may differ.

Generally you can do that using Mogrify. See

Are all your images the same file format such as PNG in the directory? Is the watermark image a PNG and is it in the same directory. If the watermark image is not a PNG or all your other images are not png, then you can keep the watermark in the same directory. If they are the same, then you need to move the watermark image to a new location.

I would suggest you create a new directory to hold your results from mogrify. Say your images are in folder1 and you have an empty directory folder2. Then

Code: Select all

cd path2/folder1
mogrify -path path2/folder2 -format png -draw 'image over 0,0 0,0 "path2/watermark.png"' *.png

If you want all image types in folder1, then do

Code: Select all

cd path2/folder1
mogrify -path path2/folder2 -format png -draw 'image over 0,0 0,0 "path2/watermark.png"' *

This will make png output images. If you want a different output, then change -format, such as -format jpg. If your watermark image is not png, then change that suffix.

If you are using IM 7, then put "magick" before mogrify.
