Display was designed to display single images for viewing. It always has at least a 1 second mandatory delay.
if you want fine control of delays use animate instead.
Code: Select all
convert image1.png image2.png image3.png miff:- |\
animate -delay 1000 -loop 0 -
A convert is needed as animate only takes one image argument.
The options for animate override any options that may be present in the input images. They could also have been set in convert, though -delay must be given BEFORE images are read, or "-set delay 1000" can be given AFTER images have been read in "-loop 0" is an output setting, so can appear anywhere.
