## What it is
gopdf is a Go library for programmatically generating PDF documents. It supports Unicode font embedding, drawing shapes and images, text alignment, and password protection.

## Use cases
- generate pdf invoices in go
- create pdf reports with unicode text
- embed chinese japanese korean fonts in pdf
- add images to pdf documents programmatically
- password protect generated pdfs

## When to choose
- you need to generate PDFs from a Go application
- you need CJK or other Unicode font support in generated PDFs
- you want a lightweight pure-Go PDF writer without external dependencies

## When to avoid
- you need to parse or edit existing PDFs rather than create them
- you need advanced layout engines like HTML-to-PDF conversion
- your project is not written in Go

## Facets
- artifact type: library
- maturity: active
- function: pdf, image-processing, templating
- domain: pdf, files, developer-tools
- platform: go, cross-platform
- tags: pdf-generation, unicode-fonts, ttf-embedding, document-generation
