Sheety

Sheety is a sprite-sheet manipulation program written in Rust.

Usage

There are 4 commands in sheety. - cat: allows concatenating, merging several sprite sheets together - slc: allows slicing a sprite sheet to extract juste one or more consecutive images from it - del: allows removing one or more consecutive images from a sprite sheet - rev: allows reversing the order of images of a sprite sheet

The cat command

sheety cat -S 128x96 -i image1.png -i image2.png -i image3.png

This will concatenate image1.png, image2.png and image3.png, considering a sprite size of 128 by 96 pixels. If you wish define the sprite size individually per image, do this instead:

sheety cat -i image1.png -s 128x96 -i image2.png -s 128x96 ...

You can also define the number of cells in the sheet, using a -:

sheety cat -i image.png -s 3-4

Or, you can include single images with single

sheety cat -i single_image.png -s single

You can define a custom distribution of sprites with the -d option. -d "columns <num>" and -d "lines <num>" will set the amount of columns, and lines, to <num>, respectively. -d "packed columns/lines" packs the sprites together, favoritising column/line length, respectively. The default, if not specified, is -d "packed columns".

The slc and del commands

sheety slc 4-8 -i image.png -s 4-6 -d "packed lines"

This will only keep images 4 through 8 (8 excluded) of image.png, distributing the result with "packed lines".

sheety del 4-8 -i image.png -s 4-6 -d "packed lines"

This will do the same, but delete images 4 through 8 instead of keeping only them.

sheety del 7- -i image.png -s 4-6

If no end point is specified, images up to the end will be affected.

The rev command

sheety rev -i image.png -s 100x100

This will reverse the order of sprites in image.png.
