Using ImageMagick to repeat or "tile" an image

In case you want plain tiles, without shifting down the second column and the rest of the even columns, you can use this script:

convert -size 800x600 tile:Ball.jpg Tiles.jpg

(probably the majority of people landing on this question want such plain tiles, like I did)

My "Ball.jpg" is 200 x 200 pixels, so this script creates a 4x3 tile image.

For ImageMagick 7 users, replace convert with magick.

Even though you did not mention anything about context of usage, I will put it here so more people are aware. Fred's scripts are for non-commercial use. I ended with an alternative solution, however, principle is the same:

1. Creating shifted tile by:

   convert _orange_270.jpg -roll +0+135 _orange_270_r.jpg

2. Create a column of regular tiles:

   montage _orange_270.jpg +clone +clone +clone -tile x4 -geometry +0+0 _1col.jpg

3. Create a column of shifted tiles:

   montage _orange_270_r.jpg +clone +clone +clone -tile x4 -geometry +0+0 _2col.jpg

4. Combined regular and shifted columns:

   montage -geometry +0+0 _1col.jpg _2col.jpg _2cols.jpg

5. Created full tiled image using last output from point 4:

   convert _2cols.jpg -write mpr:tile +delete -size 1920x1080 tile:mpr:tile _wallpap.jpg

Result:

Thanks to Fred at Fred's ImageMagick Scripts, here's the solution:

infile="tile.png"

h2=`convert $infile -format "%[fx:round(h/2)]" info:`

convert $infile \( -clone 0 -roll +0+$h2 \) +append -write mpr:sometile +delete -size 1000x500 tile:mpr:sometile output.png

This is exactly what I was looking for.

If on a unix-like system with ImageMagick, you could just use my script, tileimage at http://www.fmwconcepts.com/imagemagick/tileimage/index.php.

It provides numerous variations on the flipping, rotation and offsets.

If non-commercial use, then it is free, If commercial use, then contact me for a license.
