Hi

Is -clone the correct operator here? Single input image two outputs

Code: Select all

convert stack.tiff \( -clone 0 -depth 16 +compress -alpha off out.png \) -depth 16 +compress -alpha off out.tiff

error

convert: unable to open image 'out.png':

Tried a number of variations +clone, -clone 0--1, clone -1 same error.

You have to explicitly call +write inside parenthesis. So

Code: Select all

convert stack.tiff \( -clone 0 -depth 16 +compress -alpha off +write out.png \) -depth 16 +compress -alpha off out.tiff
