Imgpro

Imgpro is a multifunctional image information recognition library, supporting a variety of image formats. And it can be run in the browser through WebAssembly(wasm).

Online Demo: imgpro

Usage

Initial

$ go get github.com/echosoar/imgpro

Use in code

import (
  "github.com/echosoar/imgpro"
)

func main() {
  // run by file path
  result := imgpro.Run("./test/imgs/go.png", []string{"size", "type"})
  // you can also run by file binary data
  // result := imgpro.RunBinary(binary, attributes)
  
  if result["size"].Int != 60746 {
    panic("size error")
  }
  
  if result["type"].String != "png" {
    panic("type error")
  }
}

Method

Run

Get image information by local file path

Param Index	Param Name	Type	Examples
0	filePath	string	"./test/imgs/go.png"
1	attributes	[]string	[]string{"size", "type", "rgba", "hue", "qrcode"}

import (
  "github.com/echosoar/imgpro"
)

func main() {
  result := imgpro.Run("./test/imgs/go.png", []string{"size", "type", "rgba", "hue", "qrcode"})
}

RunBinary

Get image information by file binary data

Param Index	Param Name	Type	Examples
0	fileBinary	[]byte	reader.Read(binary)
1	attributes	[]string	[]string{"size", "type", "rgba", "hue", "qrcode"}

import (
  "bufio"
  "os"

  "github.com/echosoar/imgpro"
)

func main() {
  fileHandler, err := os.Open(filePath)
	if err != nil {
		panic("open error")
	}
	defer fileHandler.Close()
	fileBytes := make([]byte, size)
	reader := bufio.NewReader(fileHandler)
	_, readErr := reader.Read(fileBytes)
	if readErr != nil {
		panic("file read error")
	}
  result := imgpro.RunBinary(fileBytes, []string{"size", "type", "rgba", "hue", "qrcode"})
}
