3 AristotlePagaltzis 13 !!! Usage Examples
14
15 ! Resizing
2 AlastairPorter 16
17 convert -sample width x height input.jpg output.jpg
3 AristotlePagaltzis 18
2 AlastairPorter 19 The widths/heights can also take % values. It scales proportionally, so going 25%x25% on a non-square image will still make it come out non-square
20
21 ! Joining images together
22
23 convert files +append output.jpg
3 AristotlePagaltzis 24
25 The +append appears to join them together left to right. -append possibly does something else. Haven't really looked into it.

36 2. Join them together

2 AlastairPorter 38 convert *.jpg +append output.jpg
