Seiyuu Shirt Generator

This project is a web app for generating custom meme shirt assets inspired by seiyuu culture, especially the format:

日本語は全て<Insert your oshi>から学んだ

I built it to remove the usual PSD/manual-editing pain and make the workflow reproducible: type, preview, export, print.

What it does

• Design selection from preset styles/templates
• Text customization for meme phrase + naming
• Preview mode for quick visual checks
• Theme variants (e.g. black/white text modes)
• Output tools to copy/download assets as high-quality PNG for print-shop use

Engineering focus

The hard part wasn’t “making a form,” it was getting output quality and consistency right:

• Canvas-based rendering pipeline
• Visual balance and layout tuning
• Reliable high-resolution export
• Font rendering behavior inside canvas
• Cross-platform differences (same design, different environment behavior)

Practical validation

I haven’t printed one personally yet, but a friend asked for this meme shirt template, used this tool, and successfully produced a shirt from it.
