# annoter des images en fonction de la taille de chaque image

# https://stackoverflow.com/questions/58621445/imagemagick-how-to-create-an-annotation-that-would-fit-its-size-into-any-image?newreg=53997a2d9b724f1fb5c70113ea3c1332

# ==========================================================
# Using ImageMagick version 6 or 7 you can make a label sized to fit any input image, with a semi-transparent background, and composite it at the bottom of the input image to get the result you describe. Here is a command with IM 6 that does it...
# 
# convert input.png -set option:size %[w]x \
#    -fill white -background "#00000080" \
#    \( label:"This is my text." \
#       -virtual-pixel background -distort SRT "0.8 0" \
#       -virtual-pixel none -distort SRT "0.8 0" \) \
#    -gravity south -composite result.png
# That uses the width of the input image "%[w]" to set the width of the label. It sets the text color to white and the background to semi-transparent black, "#00000080".
# 
# Inside the parentheses it creates your label. It uses "distort SRT" to scale the label down a bit to pull it in from the edges. Then it scales the label down a bit more to add some transparent space around it.
# 
# After the label is created it sets the gravity to "south" and composites the label onto the input image. It finishes by writing the output file.
# 
# Using IM 7 you'll need to change "convert" to "magick". For Windows change the continued line backslashes "\" to carets "^" and get rid of the backslashes that escape the parentheses.
# 
# Edited to add: Normally you'd use "-size WxH" ahead of making a "label:" to constrain it within particular dimensions. I used "-set option:size" instead because it allows for using percent escapes like "%[w]" with IM 6. That way the label dimensions are relative to any input image width.
