Spritesheet Manager is a Krita plugin that adds functionalities to aid the creation of spritesheets and to build atlas. The idea stemmed from the need to facilitate the creation of sprite sheets for Hums of the Soul.
Spritesheet Manager is non-destructive, as it — very smartly, I might add — creates new files instead of rewriting the original ones, leaving the original file untouched. The plugin automatically detects most of the necessary inputs from the original file, needing only the desired tile size. It supports empty padding, or anti-pixel-bleed padding, surrounding completely the tiles on all sides. It also comes with a preview window, which shows the outcome of the chosen settings for inspection before committing into the full render.
This was a fun and easy project to work on, which in return tremendously helped in the creation of spritesheets for Hums of the Soul. To this day, I'm still not sure if Krita was the best choice for this, but it was what I used and it did work. I just know, the first spritesheets which I added padding to, where I added every padding line and anti-bleed pixel by hand, was a painfully boring chore that took way too much time.
This plugin started as Tileset Padder, when it was meant to work only on tile sets with square shapes. It then matured to work on any type of spritesheet, including rectangular-shaped tiles, since I needed to use it on the character's sprite sheets.
