HexDissect

Development Process:

• On 1st paid download of a product, I release or develop the next update. On 3rd paid download of a product, I do another update. On 7th paid download, another update. On 12th, another. And again on 18, 25, 33, 42, 52, etc. 

• To gain access to the updated versions of a file, a minimum price must be paid. Base product is free or donate. Update 1 is 1$. Update 2 is 2$, update 3 is 3$, so-on-and-so-forth. 
• So if you like a thing you downloaded, toss me a buck so I know it's worth pursuing, and I'll continue development!

HexDissect — Simple Pixel Art Slicer

HexDissect is a small command-line utility for pixel artists and game developers who want a fast, no-nonsense way to break images into smaller, separate images.

You drop images into a folder, run the tool, define the relevant properties of the base sprite sheet, and HexDissect slices everything cleanly and predictably. No GUI, no project files, no metadata — just files in, files out.

This tool was built for grid-aligned pixel art workflows where precision and repeatability matter more than flexibility.

What It Does

• Scans an input folder for supported image files

• Allows slicing one image or all images at once

• Cuts images into sprites of a user-defined dimensions

• Aborts if an image is not divisible

• Outputs PNG images with fixed-width serial numbering

• Automatically creates folder for the output files

What It Does Not Do

• No graphical interface

• No resizing, padding, trimming, or auto-detection

• No config files or background services

• No “smart” behavior — exact input is required

This is a deterministic utility, not a creative assistant.

Folder Workflow

1. Put images in:   insputs/
2. Run HexDissect
3. Enter sprite sheet slicing properties
4. Get results in: outputs/<image_name>/

Third-Party Libraries

HexDissect includes the following third-party single-header libraries, which are not authored by this project:

• stb_image.h — image loading

• stb_image_write.h — image writing

Both libraries are part of the stb collection by Sean Barrett and are used under their respective permissive licenses.

All credit for those components belongs to their original author(s).

AI / Tooling Disclosure

All specifications, architectural decisions, and final validation were performed manually. ChatGPT was used to accelerate implementation and reduce boilerplate, not to autonomously design or ship the software.
