PHP - Imagettftext() Failure

I need to draw various font sizes onto a canvas to create a web service. Wanting to protect my HD assets, the intent is to use PHP to populate the image with the necessary text, and then scale down the image before presenting it to the user.

A similar service already exists, a tool to allow the public to make user generated content for a card game.

The problem ever, is that PHP does not seem to handle font sizes very well. I created this sample code to demonstrate my issue.
Here is a sample output from the code below
 

<?php
    $img = imagecreatetruecolor(750, 530);
    
    $black = imagecolorallocate($img, 0, 0, 0);
    $gray = imagecolorallocate($img, 125, 125, 125);
    $white = imagecolorallocate($img, 255, 255, 255);
    
    $font = realpath('../fonts/micross.ttf');
    
    $size = 12;
    $spacing = 20;
    
    for ($x = 0; $x <= 25; $x++) {
        $box = imageftbbox($size + $x/10, 0, $font, "The longer the phase the more apparent the size difference should be");
        $boxWidth = $box[2] - $box[0];
        
        imagefilledrectangle($img, 5, $x*$spacing+5, $boxWidth+5, ($x+1)*$spacing+5, $gray);
        
        imagefttext($img, $size + $x/10, 0, 5, $spacing*($x+1), $white, $font, "The longer the phase the more apparent the size difference should be Font Size ".($size+($x/10)));
    }
    
    imagejpeg($img);
    imagedestroy($img);
?>

You can see how despite the font size steadily increasing by 0.1, it sporadically jumps at what seem at first like random intervals, however if you increase the number of loops and log the data, you can see that it alternates between increasing every 0.7, and 0.8. Unfortunately that doesn't help me any, just some insight.

if($last != $boxWidth)
{
    $last = $boxWidth;
    echo $boxWidth." ".($size+($x/10))."<br>";
}

This outputs the current width and font size each time the text width changes.
I've compiled a sample output for you guys to look at here

Hopefully I've provided enough information to get some help, this has been very frustrating.

After working with the sample imagecreatefromjpeg provided in the PHP manual, I successfully got a result (after clearing my cache) from

imagecreatefromjpeg($im, $file);

I've gotten a good education after navigating this function over the past week, and loaded it with ECHO messages to give me insight.

Everything was going fine.

And then, this ONE test image came along.

Apparently, the image (which is as good aj peg as I can find) FAILS the if(!im) test.

When I used echo $im;  

i discovered that when images pass through the function, they receive a "Resource" name.

Images that FAIL are NOT named.

This image gets a Resource name, yet FAILS. Is there a problem with my logic? A problem with the image? What would cause this? How can I verify?

I am working on an e banking web app. So i was stuck on the transferring to the same bank page.. I have spent a lot of time to check where the errors are to no avail. The issue is the code doesnt work it gives a blank page...
