I'know this is an old topic, but there is a easier way of solving this problem. Just try this simple steps:

1. Strip data:image/png;base64 from URI using explode
2. Concatenate data://text/plain;base64, with what is left from the stripped URI
3. Use the result string(base64) as argument of FPDF Image()

Example:

$dataURI= "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAPCAMAAADarb8dAAAABlBMVEUAAADtHCTeKUOwAAAAF0lEQVR4AWOgAWBE4zISkMbDZQRyaQkABl4ADHmgWUYAAAAASUVORK5CYII=";

$img = explode(',',$logo,2);
$pic = 'data://text/plain;base64,'. $img;

$pdf = new FPDF();
$pdf->AddPage();
$pdf->Image($pic, 10,30,0,0,'png');
$pdf->Output();

Remember of choose the correct image type on Image() function.
