imagemagick comosite proportion to image size - imagemagick

Question

I want to place year on picture with imagemagick. I have about 4000 pictures. I try to do it with imagemagick using the -compose parameter.
Logo is 200x67 px.
But all pictures is not the same size. How i can add proportional size of year on each image?
Example image
I not yet try imagemagick, but i placed logo to two different pictures with photoshop.
Or imagemagick handles this? Or i can put text on each image with defined font size? Or better convert all images to one size? If that, can imagemagick tell me wich is smallest picture?

Answer 1

I suggest you do the following:
Create the logo in a bigger size, so you can scale it down later
Then loop through all images:
Get image size of image:
$size_array = getimagesize ( $image_src );
$width = $size_array[0];
$height = $size_array[1];
Depending on image size, scale a copy of logo down
Compose logo over image

Answer 2

I made script http://pastebin.com/HdBMx2Zm It looks good in my XP machine (ACDSee) and also on windows 7 (windows integrated image viewer). In some pictures year is little bit bolder, but it is ok.
#!/bin/bash
#
#
#
# find /media/sf_test/meklee/ -type f -iname "*.jpg" -exec /root/imagick_script.sh "{}" \;
#
# depends on jhead and imagemagick
# if call find from another file, then is possible to count all pictures, place count on file and in imagick_script.sh
# decrase that amount by 1.
#
# in script some directory names is in Latvian :)
