What is the issue with centering a bitmap in PHP and how can it be resolved?

When centering a bitmap in PHP, the issue is that the image may not be properly aligned in the center of the canvas. This can be resolved by calculating the center coordinates of the canvas and then adjusting the position of the bitmap accordingly. 

$canvasWidth = 800;
$canvasHeight = 600;
$bitmapWidth = 200;
$bitmapHeight = 150;

$centerX = ($canvasWidth - $bitmapWidth) / 2;
$centerY = ($canvasHeight - $bitmapHeight) / 2;

// Place the bitmap in the center of the canvas
imagecopy($canvas, $bitmap, $centerX, $centerY, 0, 0, $bitmapWidth, $bitmapHeight);
