<?php
function displayToken($token, $fontSize, $theme)
{
	if (($fontSize = (int) $fontSize) < 22) {
		$fontSize = 22;
	}
	if ($fontSize > 100) {
		$fontSize = 100;
	}
	$length = strlen($token);
	$padding = 10;
	$fontWidth = $fontSize;
	$fontHeight = floor($fontWidth * 1.5);
	$width = $fontWidth * $length + $padding * 2;
	$height = $fontHeight;
	$image = imagecreatetruecolor($width, $height);

$height of type double is incompatible with the type integer expected by parameter $height of imagecreatetruecolor().

	addBackground(
		$image,
		$width,
		$height,
		$theme & THEME_OPAQUE_BACKGROUND,
		$theme & THEME_NOISY_BACKGROUND,
		$theme & THEME_HAS_GRID,
		$theme & THEME_HAS_SCRIBBLE,
		$theme & THEME_MORPH_BACKGROUND
	);

	$font = __DIR__ . DIRECTORY_SEPARATOR . 'verase.ttf';

	if (function_exists('imagefilter')) {
		imagefilter($image, IMG_FILTER_GAUSSIAN_BLUR);

It seems like $image can also be of type false; however, parameter $image of imagefilter() does only seem to accept resource, maybe add an additional type check?

	}

	$hasShadow = ($theme & THEME_SHADOWED_TEXT);
	for ($i = 0;$i < $length;$i++) {
		$color = imagecolorallocate($image, rand(150, 220), rand(150, 220), rand(150, 220));

It seems like $image can also be of type false; however, parameter $image of imagecolorallocate() does only seem to accept resource, maybe add an additional type check?

		$size = rand($fontWidth - 10, $fontWidth);
		$angle = rand(-30, 30);
		$x = $padding + $i * $fontWidth;
		$y = rand($fontHeight - 15, $fontHeight - 10);

$fontHeight - 10 of type double is incompatible with the type integer expected by parameter $max of rand().

$fontHeight - 15 of type double is incompatible with the type integer expected by parameter $min of rand().

		imagettftext($image, $size, $angle, $x, $y, $color, $font, $token[$i]);

It seems like $image can also be of type false; however, parameter $image of imagettftext() does only seem to accept resource, maybe add an additional type check?

		if ($hasShadow) {
			imagettftext($image, $size, $angle, $x + 2, $y + 2, $color, $font, $token[$i]);
		}
		imagecolordeallocate($image, $color);

It seems like $image can also be of type false; however, parameter $image of imagecolordeallocate() does only seem to accept resource, maybe add an additional type check?

	}

	header('Content-Type: image/png');
	imagepng($image);

It seems like $image can also be of type false; however, parameter $image of imagepng() does only seem to accept resource, maybe add an additional type check?
