基于文本PHP的动态图像
我想使用 GD 生成精美的字体文本图像。
我发现:
<?php
// Settings
$sText = 'This is just a test!'.@$_GET['t']; // Text of heading
$sFont = 'Bryant-Bold.ttf'; // Default font for headings
$sMain = @$_GET['c'] ? $_GET['c'] : 0xF2AB27; // Get a font or default it
// Calcuate the width of the image
$arSize = imagettfbbox(24, 0, $sFont, $sText);
$iWidth = abs($arSize[2] - $arSize[0]);
$iHeight = abs($arSize[7] - $arSize[1]);
// Create the image
header("Content-Type: image/png"); // Set the content-type
$hImage = imagecreatetruecolor(200, 24);
ImageFill($hImage, 0, 0, IMG_COLOR_TRANSPARENT);
imagesavealpha($hImage, true);
imagealphablending($hImage, false);
imagettftext($hImage, 20, 0, 0, 24, $sMain, $sFont, $sText); // Draw the text
imagepng($hImage); // Generate the image
imagedestroy($hImage); // Destroy it from the cache
?>
但它看起来像这样: http://img638.imageshack.us/img638 /4575/testphp.png (砍掉部分)
I'd like to generate a fancy font text image using GD.
I have found:
<?php
// Settings
$sText = 'This is just a test!'.@$_GET['t']; // Text of heading
$sFont = 'Bryant-Bold.ttf'; // Default font for headings
$sMain = @$_GET['c'] ? $_GET['c'] : 0xF2AB27; // Get a font or default it
// Calcuate the width of the image
$arSize = imagettfbbox(24, 0, $sFont, $sText);
$iWidth = abs($arSize[2] - $arSize[0]);
$iHeight = abs($arSize[7] - $arSize[1]);
// Create the image
header("Content-Type: image/png"); // Set the content-type
$hImage = imagecreatetruecolor(200, 24);
ImageFill($hImage, 0, 0, IMG_COLOR_TRANSPARENT);
imagesavealpha($hImage, true);
imagealphablending($hImage, false);
imagettftext($hImage, 20, 0, 0, 24, $sMain, $sFont, $sText); // Draw the text
imagepng($hImage); // Generate the image
imagedestroy($hImage); // Destroy it from the cache
?>
But it looks like this: http://img638.imageshack.us/img638/4575/testphp.png

您的输出图像使用固定宽度 200!
您应该动态计算宽度 - 可能您需要使用变量
$hImage
:You're using a fixed width of 200 for your output image!
You should be calculating the width dynamically - probably the variable
$hImage
is what you need to use:
