Code: Select all
convert 01.png 02.png 03.png 04.png -bordercolor white -border 12 ( -clone 0,1 +append ) -delete 0,1 ( -clone 0,1 +append ) -delete 0,1 -append -resize 1000 -quality 75 1234.png
Then use -resize "widthx1000>" if landscape and -resize "widthx1000" if portrait.
Any workaround ? for example, is there any way to force resize only for height ?
