magic

This is a simple GoLang package that validates the content of a byte array to a file type. The need for this package became evident when I needed to validate a byte array as a png file to then forwarded to a waveform point extractor.

Installation

To install magic, you can go get this like you do any other go package as follows

go get github.com/samcrosoft/magic

---

Example

Want to see how simple it is to use this package,

    sImagePath := "./corpus/image/png-sample.png"
	if oBytes, err := ioutil.ReadFile(sImagePath); err == nil{
		oType := &types.PNGType{}
		if bValid, oErr := IsBytesContentAValidType(oBytes, oType); bValid == true{
			// then image is a valid png
		}
	}

At the moment, there are a couple of image type formats

1. types.PNGType
2. types.JPEGType

Tests

To run the tests, just run go tests
