Basic

For example, if you saved the jar to your server's root directory and want to generate images for all regions, you would use

java -jar region-preview.jar world/region/

To get smaller images, just add the scale option

java -jar region-preview.jar world/region/ -s 2

Large combined image

To stitch together multiple images into one large image, use the --stitch... options, e.g. to create a 4x2 region image starting at -2,-1:

java -jar java -jar region-preview.jar world/region/ -s 2 --stitch --stitchStartX=-2 --stitchStartZ=-1 --stitchWidth=4 --stitchHeight=2
