    Its important to understand that the boolean flag : $FIT is used as a MAXIMUM boundary of either X or Y

    If you use a physical image with a size of 128x256

    scaleImage(200, 100, true); Will scale Y to 100 and X will be calculated
    scaleImage(100, 120, true); Will scale X to 100 and Y will be calculated

    $FIT is a LIMITER which is why it requires both an X and a Y for $FIT=true

    CORRECTION

    Replace

    echo 'img src="data:image/jpeg:base64,'.base64_encode($image).'">';

    With

    echo '<img src="data:image/jpeg:base64,'.base64_encode($image).'">';

    Simple method to load an image from file, resize and display without writing to disk.
    tested on jpg, gif and bmp
    <?php
    $image    = new Gmagick( "yourimage.jpg");
    $image->scaleimage(300,0);
    echo     'img src="data:image/jpeg:base64,'.base64_encode($image).'">';
    $image->destroy();
    ?>
