Nybbit/SpritesheetGenerator

A spritesheet generator for your project

Spritesheet Generator

What is this?

This code generates a spritesheet from textures in a specified directory. It also has simple serialization so you can import and already generated spritesheet. Feel free to use this in any of your projects and modify the code, attribution would be nice but it's not required :simple_smile:

Example

Code

/*
 * Generate a spritesheet from textures with the
 * extensions PNG, JPEG, and BMP in the
 * "texture" directory
 */
auto sheet = Spritesheet("bin/textures", PNG | JPEG | BMP);
sheet.exportSpritesheet("spritesheetData"); // Export the spritesheet to folder 'spritesheetData' for easy import later
sheet.getUv("subfolder/a"); // Get texture 'bin/textures/subfolder/a.png'

// Create an ungenerated spritesheet for import
auto sheet2 = Spritesheet();
/*
 * Import spritesheet from folder 'spritesheetData'
 * Note: you don't need the original images if you're importing,
 * you only need image.png and data.dat (which are generated
 * by exportSpritesheet())
 */
sheet2.importSpritesheet("spritesheetData");
sheet.getUv("subfolder/a"); // Get texture

Spritesheet output

Dependencies

Required

• stb_image.h (for image decoding)
• stb_image_write.h (for image encoding)
• glm (for ivec2 and vec4 - easily replacable)

Building

Requires a compiler that supports C++17 (for filesystem). Alternatively, use boost's filesystem
