It seems that Mac OS' Finder cannot deal with large TIFFs (in my case > 5000x3000) that are LZW compressed. The "enfuse" utility creating the original file produced an LZW compressed 4-channel 16-bit TIFF (despite called with --compression=none ) which is a bad choice. identify -verbose is very ...

I completely remove the alpha channel of a TIFF resulting from a tool that will only output 4-channel TIFFs by convert inputimg -alpha off outputimg (It seems to work well with the same file as input and output.) The problem is that Mac OS' (10.11) Finder preview will only show a completely black ...

To complete my command - example:
It's useful to append -contrast-stretch 0x0 or -normalize after -statistic ..., else the highest luminance will be very low for smaller geometries.

Yes, this is what I tested some hours ago:
Your post is very helpful to find a performant solution, thank you for sharing!

Is there a special command to get areas of interest (e. g. by finding clusters of high contrast) in ImageMagick?
I imagine a command like this
where -interest is the maximum number of areas with the highest interest to be found, the output would be a crop geometry.

In the meantime it works in the way described here. My post could be deleted.

I'm building a little script that should combine clips from different positions from a large image. First, I build several clips like this: convert "$infile" -crop "${box_w}x${box_h}+${x}+${y}" "$clipFile" Along with this I build the final command that appends all those clips to the final image ...
