How to make a photomontage?

[Fafou]

Hello,

I make a lot of photo for my job and I have to do photomontages.
Each montage is composed of 30 photos, 1 column, 30 lines.
Every photo is in the portrait format and is named IMG_xxxx (number increasing)
Finally I have to resize the montage in 645*29040.

I would like to do the maximum of tasks automatically.
- Open the 30 photos.
- Put one and one under the others.
- Resize the montage.

May someone make a script which can do it please, or explain me how to do? Thank you for your help.

P.S: Excuse me for the mistakes, I don't speak English very well.

Try:

Code: Select all

convert ( IMG_0001.jpg -append IMG_0002.jpg -append IMG_0003.jpg -append ) -resize 645x29040 append.png

OR

Code: Select all

montage IMG_0001.jpg IMG_0002.jpg IMG_0003.jpg -tile x3 | convert -resize 645x29040 - tile.png

I tried with 3 photos in a directory:

Result for the first command:

Code: Select all

convert ( IMG_9346.JPG -append IMG_9347.JPG -append IMG_9348.JPG -append ) -resize 645x2904 append.png
bash: Erreur de syntaxe près du symbole inattendu « IMG_9346.JPG »

( = Error of syntax "next to" the unexpected symbol "IMG_9346.JPG")

I tried with double quotes, same result, and I check the image's names; it's correct.

And for the second command:

Code: Select all

montage IMG_9346.JPG IMG_9347.JPG IMG_9348.JPG -tile x3 | convert -resize 645x2904 - tile.png
montage: missing an image filename `x3'.
convert: missing an image filename `tile.png'.

Thank for your help.

what is your IM version and are you on Unix or Windows? Are all the images the same size?

You did not say how you were going to use the code and I am afraid I do not know about Bash scripts.

With the first example you may need to escape the ( & ) I use \( & \)

You could also try it without the resize first and see if that part works:

Code: Select all

convert IMG_9346.JPG -append IMG_9347.JPG -append IMG_9348.JPG -append append.png

With the second example I would try adding ( & ) with the escapes as well so it becomes \( & \)

Code: Select all

\( montage IMG_9346.JPG IMG_9347.JPG IMG_9348.JPG -tile x3 \) | convert -resize 645x2904 - tile.png

Again try the first part of the code then add the resize part later

Code: Select all

montage IMG_9346.JPG IMG_9347.JPG IMG_9348.JPG tile.png

try

convert image1 image2 ... image30 -background black -gravity center -append -resize "645x29040!" outputimage

see

http://www.imagemagick.org/script/comma ... php#resize
http://www.imagemagick.org/script/comma ... p#geometry

A bash script could be generated if you are on Unix, but we need to know how your images are actually numbered. Do they have leading zeros as image_0001 or image_1? Are they all the same size? If not what background do you want for the smaller ones. More details are needed.

IT WORKS!

I'm on Ubuntu 8.04.2.
All the images have the same size.

I do: convert image1 .... image 30 -append -resize "645x29040!" Page_1.jpg and it works.
I'm just going to make a bash script with the name of the first image to insert, and with a for loop, Linux will do the rest. :p

Thank you everybody!

You do NOT need to -append after every image.

You can just read all the images in and then -append.

For example

Code: Select all

convert IMG_9346.JPG  IMG_9347.JPG  IMG_9348.JPG   -append   append.png

Also remember with the later releases of IM -append will also follow justification suggestions made by -gravity, at aleast for the direction perpendicular to the direction of the append. EG: horizontally.

If you like spaces bettwen the images you can also add a -splice or -border option before the append with the appropriate -bordercolor.
