Offset Stacked Images

[Wonkey Donkey]

Hi all,

I'm having difficulty working out how to offset images which I have layered on top of one another by a specified amount. My code at present is as follows:

Code: Select all

convert "%FilePath%cathedral.jpg" "%FilePath%cathedral2.jpg"
-bordercolor white -border 6 -bordercolor grey60 -border 1 -bordercolor none -background none -gravity center
( -clone 0 -rotate -14.8837 )
( -clone 1 -rotate 17 )
( -clone 0 -rotate 5 -gravity center ( -rotate -12 "%FilePath%stamp.png" ) -composite )
-delete 0,1 -border 320x221 -crop 640x442+0+0 +repage -flatten -trim +repage -background black ( +clone -shadow 60x4+4+4 ) +swap -background none -flatten -resize 320x221^ "%FilePath%churchmicro.png"

Also, any other "optimisations" / simplifications people can provide to the above which either improve or do not deviate from the current result would be much appreciated.

Thanks in advance.

Are you trying to acheve this effect: layers

Not quite. I'm looking to offset the images all a "small" amount in different directions from the centre point of the base image. It should look like the images are all in a single pile, but not all sharing the same centre point. I'll have a look through that page and see if I can understand how it is working and translate it to my code.

see -mosaic or -layers merge using -page to offset your images. -mosaic will expand your result to cover all the offset and not crop the base image.

http://www.imagemagick.org/Usage/layers/#mosaic

try this

convert -page +0+0 rose: -page +10+10 rose: -page +20+20 rose: -background none -mosaic 1layer.png

The 'layer offset' or virtual canvas offset, or simply virtual offset, can be adjusted using the -repage option with a '!' flag. See Repage Image Meta-data
http://www.imagemagick.org/Usage/basics/#page

You may need to clone images into parenthesis before doing this is you want different offsets.

Note you can also change offsets using -set page which can allow you to use a mathematical formula to calculate an offset. It is a bit like Animated Distorts,
http://www.imagemagick.org/Usage/anim_mods/#distort
or how the 'delay' was modified in the third example of Color Morphing
http://www.imagemagick.org/Usage/anim_mods/#morph
but just changing the 'page' offset instead.
