微信公众号推送文图片封面会自动剪切，封面图片尺寸比例如果不是9:5会出现显示不完整，为方便不会使用图片编辑的客户能生成合适比例封面写了这个php代码功能，实现原理是在一张900*500的图片上加封面图片，就是图片水印，背景透明。

<?
header("Content-type: image/png");

//原始图像
$dst = "a.png";
	//实测900*500比例尺寸图片已不会出现裁剪图片边缘的问题，只需要发送多图文消息时注意标题文字是否会挡住图片内容即可。
	$minx=900;
	$miny=500;

//得到原始图片信息
$dst_im = imagecreatefrompng($dst);
$dst_info = getimagesize($dst);

//水印图像
$src = "b.jpg";
$src_im = imagecreatefromjpeg($src);
$src_info = getimagesize($src);	

$nx=$src_info[0];
$ny=$src_info[1];

if($nx>$minx || $ny>$miny){
	//获取大图信息
	$maxx=$src_info[0];//宽
	$maxy=$src_info[1];//长
	$maxt=$src_info[2];//格式
	$maxm=$src_info['mime'];//mime类型


	//缩放判断
	if(($minx/$maxx)>($miny/$maxy)){
		$scale=$miny/$maxy;
	}else{
		$scale=$minx/$maxx;	
	}

	//对所求值进行取整
	$minx=floor($maxx*$scale);
	$miny=floor($maxy*$scale);
	
	//添加小图
	$minim=imagecreatetruecolor($minx,$miny);

	//缩放函数
	imagecopyresampled($minim,$src_im,0,0,0,0,$minx,$miny,$maxx,$maxy);
	//imagejpeg($minim);
	$src_im=$minim;
	$nx=$minx;
	$ny=$miny;
}


//水印透明度
$alpha = 100;

	$nwx=($dst_info[0]-$nx)/2;
	$nwy=($dst_info[1]-$ny)/2;
	

				//imagealphablending($dst_im , false);//关闭混合模式，以便透明颜色能覆盖原画板
				//imagefill($image , 0 , 0 , $bg);//填充
				imagesavealpha($dst_im , true);//设置保存PNG时保留透明通道信息
	
	
//合并水印图片
imagecopymerge($dst_im,$src_im,$nwx,$nwy,0,0,$nx,$ny,$alpha);

//输出合并后水印图片
imagepng($dst_im);
imagedestroy($dst_im);
imagedestroy($src_im);
?>

注意路径问题

$dst = "./a.png";
$dst = "/a.png";
