{
var options = new BitmapFactory.Options
{
InJustDecodeBounds = true
};
File file = new File(fileName);
long lengthMB = file.Length() / 1024;
BitmapFactory.DecodeFile(fileName, options);
int width = options.OutWidth;
int height = options.OutHeight;
string type = options.OutMimeType;
file.Dispose();
return new AccidentMediaViewModel
{
Height = height,
MimeType = type,
Filename = fileName,
SizeKb = lengthMB,
Width = width
};
