Preview Blizzard .blp texture files directly in VS Code — no external tools required.

Features

• Opens .blp files as image previews automatically
• Displays image metadata: format, alpha depth, mipmap count, and file size
• Supports BLP1 and BLP2 texture files:
  • BLP1 JPEG
  • BLP1 RAW1 — palettized (256-color)
  • BLP2 DXT1 — no alpha or 1-bit alpha
  • BLP2 DXT3 — explicit 4-bit alpha
  • BLP2 DXT5 — interpolated 8-bit alpha
  • BLP2 RAW1 — palettized (256-color)
  • BLP2 RAW3 — uncompressed ARGB8888
• Respects VS Code's light/dark theme for the preview background

Usage
