How to Make Pictures into Posters ?

[ths]

hello !

I'm not very good in Image magick and i would like to do a program like : http://www.blockposters.com/
Is IM able to do that ? I saw this: http://imagemagick.org/Usage/crop/#croptile ... but is it the good tools ?
I saw pdfposter and poster (Deb package), but it will mean i must install a server ...

Thant a lot in advance, i'm not searching about ready to use solution, just direction to begin ...

Yes, IM can do that, and you were looking at the right documentation. Use

Code: Select all

convert rose: -crop 20x20 +repage rose%03d.png
mogrify -resize 2500% rose*png

to split up the image into tiles,
then resize them all to the size you want.

A better technique is to probably use 'cropping (near) equal divisions'
http://www.imagemagick.org/Usage/crop/#crop_equal

For example the 6x3 division from 'blockposters'...

Code: Select all

   convert image.png -crop 6x3@  +repage  page_%02d.png

You may like to do some resizing (enlarging) of the image to fit your pages but essentially that is how to do it.

The advantage of using equal division method is you can also generate some 'overlap' between the tiles. That will make piecing together the individual tile 'pages' easier, as the pages are slightly overlapped.
