rotateSpritesheet Documentation

Brief Description

rotateSpritesheet is an asynchronous function tgdfgfdgfdgdfghat rotates a spritesheet image by a specified number of degrees.

Usage

To use rotateSpritesheet, you need to import it from the module where it's defined. It takes an image buffer and a rotation angle as input.

import { rotateSpritesheet } from './path/to/module';

Parameters

• inputBuffer (Buffer): The input image buffer containing the spritesheet.

• degrees (Number): The number of degrees to rotate the spritesheet.

Return Value

Returns a Promise that resolves to a Buffer containing the rotated spritesheet image.

Examples

Basic usage:

const fs = require('fs').promises;
const rotatedBuffer = await rotateSpritesheet(await fs.readFile('input.png'), 90);
await fs.writeFile('rotated.png', rotatedBuffer);

Using with the sprite object:

const sprite = await sprite.generateSprite('character');
const rotatedSprite = await rotateSpritesheet(Buffer.from(sprite.image.split(',')[1], 'base64'), 45);

Notes or Considerations

• The function uses the Sharp library internally for image processing.

• Rotation is performed around the center of the image.

• Non-rectangular spritesheets may have parts cropped off after rotation.

• Large spritesheets may require more processing time and memory.

• Consider the impact on frame alignment when rotating animation spritesheets.
