I often have to arrange photos in a row with soft transitions like in panoramaphotos. Until now I've done that in Gimp. But it's a very time-consuming task, so I wanted to do it script-based. Here is my first attempt (assuming pic1 and pic2 being 150x150px):

#! /bin/bash
convert -size 250x150 xc:yellow \
pic1.jpg \
-composite \
\( pic2.jpg \( \
\( -size 150x50 gradient:transparent-opaque -rotate -90 \) \
\( -size 100x150 xc:white \) \
+append \) \
-gravity East -compose CopyOpacity -composite \) \
-geometry +100+0 \
-composite \
out.png && feh out.png

Normally I have a set of images (with different sizes) in a directory that have to be appended. So it would be nice if my script could do this task automatically. For this taskt it's silly that I have to define the final image-size at the beginning. It would be much nicer if I just could tell montage to append the images with a blurred transition. But I didn't find a way to do that.

Thanks for help

post a link to an example of each image and the result

Well it took me some time to go through old posts, from after my vacation, so I am sorry about the late reply.

Overlapping photos should be fairly straight forward, us a masked compose
http://imagemagick.org/Usage/compose/#mask The first two lines generates a gradient mask, black or one image, white for the other, with the right type of overlap.

The next line reads in the 'background' image, and enlarged (any color) so it is the same size as the mask, then the 'source' or overlay image is read in.
The images are reorderd into 'background', 'source', 'mask' and gravity set to place the source on the right hand size. Finally the images composed to
generate the gradient overlaped images.

Easy.

This is going in to IM Examples: Photo Modification, Cookbook.
http://imagemagick.org/Usage/photos/#overlap
and should appear in a day or so.

Other way is to mask the second image with transparency then, set it 'page' or virtual-canvas position (using -repage), and -mosaic, or -layer merge the two images together, which will automatically calculate the canvas size.
