Node : how to convert from varbinary to image of SQL Server datatype

问题

I'm have a SQL Server database with images of type varbinary. I need to convert the varbinary and return the image to a web page. Help would be appreciated.

I found this and it was very helpful, but I need it in reverse. Node.js How to convert to image from varbinary of MS Sql server datatype

Something like ...

var image  = new Buffer(rs.recordset[0].Image).toString('base64');
                    res.type('image/jpeg; charset=utf-8');
                    res.status(200).end(image);

<ng-template ngbSlide *ngFor="let image of images">
          <img class="center-block" src="data:image/JPEG;base64,{{image}}">
        </ng-template>

And my service is like this ...

 getImage(query){
    
       return this._http.get(this.API_URL + this.baseUrl + query)
         .map(res => res.json());
    
   }

This was the answer.

res.writeHead(200, {'Content-Type': 'image/jpeg'});
//var image = rs;
var image  = new Buffer(rs.recordset[0].Image);
res.end(image);
