0 dependency parser for Valves own .vtf (Valve Texture Format) Source Engine textures.

• Supports versions 7.1-7.5
• Full header data
• Low resolution thumbnail loading
• Complete mipmap + high-resolution texture loading

import (  
	"github.com/galaco/vtf"
	"log"
	"os"
)

func main() {
  file,_ := os.LoadFile("foo.vtf")
  texture,err := vtf.ReadFromStream(file)
	if err != nil {
		log.Println(err)
	} else {
    log.Println(texture.Header().Width)
  }
}

• Resource data is ignored (besides mipmaps) in 7.3+
• Texture with depth > 1 are unsupported. This is very rare
• Textures with zslices > 1 are unsupported. This is very rare
• Modify/export functionality

• Colour format transformation. Header properties LowResImageFormat and HighResImageFormat will provide the format.
• (Probably) support depths or zslices > 1

No where near all the possible texture configurations have been tested. It's possible some could cause issues. Any issues (including offending file) are greatly appreciated.
