内容总结：

本人是自学的php，代码书写多有不规范之处，并且有些位置的代码有重复累赘。以后需要加强。

upload_image.php: 主要是 HTML+Javascritp+Css 没什么可说的，主要就 javascript 调用 window.URL.createObjectURL(fileObj) 方法。获取图片的相对路径，并做图片的展示。

check_image.php: 1、session 用于保存从 upload_image.php 传递过来的图片的后缀名。

　　　　　　　　　 2、数据库moviesite创建，images表的创建 

    <span>$sql</span> = "<span>CREATE TABLE if not exists images                       
    (
        image_id int NOT NULL AUTO_INCREMENT, 
        PRIMARY KEY(image_id),
        image_caption varchar(15), 
        image_username varchar(15),
        image_filename varchar(15),
        image_date  datetime
    )</span>";
登录后复制

　　　　　　　　　3、使用 imagecreatetruecolor 和 imagecopyresampled 将图片大小调整为1280X960.然后将图片上传保存到指定位置。

<span>　　　　　//</span><span>将图片改为1280X960
        //新建一个指定大小的真彩色图像big</span>
        <span>$big</span> = imagecreatetruecolor(1280, 960<span>);
        </span><span>//</span><span>重采样拷贝部分图像并调整大小为1280X960</span>
        imagecopyresampled(<span>$big</span>, <span>$image</span>, 0, 0, 0, 0, 1280, 960, <span>$array</span>[0], <span>$array</span>[1]);
登录后复制

　　　　　　　　　4、如果图片已经上传，则从数据库中取图片名字

        <span>$query</span> = 'select image_id,image_caption,image_username,image_date from images where image_id='.<span>$_POST</span>['id'<span>];
        </span><span>$result</span> = <span>mysql_query</span>(<span>$query</span>,<span>$db</span>) or <span>die</span>(<span>mysql_error</span>(<span>$db</span><span>));
        </span><span>//</span><span>将结果集转换成关联数据，再将关联数组的键名当作变量名，值作为变量的值。</span>
        <span>extract</span>(<span>mysql_fetch_assoc</span>(<span>$result</span><span>));
        </span><span>list</span>(<span>$width</span>,<span>$height</span>,<span>$type</span>,<span>$attr</span>) = <span>getimagesize</span>(<span>$dir</span>.'/'.<span>$image_id</span>.<span>$_SESSION</span>['ext']);
登录后复制

　　　　　　　　　5、bool imagefilter ( resource $src_im , int $filtertype [, int $arg1 [, int $arg2 [, int $arg3 ]]] ) 对图像使用过滤器 PS图片

<span> imagefilter() 把过滤器 filtertype 应用到图像上，在需要时使用 arg1，arg2 和 arg3。

filtertype 可以是下列中的一个：

    IMG_FILTER_NEGATE：将图像中所有颜色反转。
    IMG_FILTER_GRAYSCALE：将图像转换为灰度的。
    IMG_FILTER_BRIGHTNESS：改变图像的亮度。用 arg1 设定亮度级别。
    IMG_FILTER_CONTRAST：改变图像的对比度。用 arg1 设定对比度级别。
    IMG_FILTER_COLORIZE：与 IMG_FILTER_GRAYSCALE 类似，不过可以指定颜色。用 arg1，arg2 和 arg3 分别指定 red，blue 和 green。每种颜色范围是 0 到 255。
    IMG_FILTER_EDGEDETECT：用边缘检测来突出图像的边缘。
    IMG_FILTER_EMBOSS：使图像浮雕化。
    IMG_FILTER_GAUSSIAN_BLUR：用高斯算法模糊图像。
    IMG_FILTER_SELECTIVE_BLUR：模糊图像。
    IMG_FILTER_MEAN_REMOVAL：用平均移除法来达到轮廓效果。
    IMG_FILTER_SMOOTH：使图像更柔滑。用 arg1 设定柔滑级别。</span>

　　　　　　　　 6、图片加文字

        <span>//</span><span>图片指定位置打印文字</span>
        <span>if</span>(<span>isset</span>(<span>$_POST</span>['emb_caption'<span>]))
        {    </span><span>/*</span><span>
            array imagettftext ( resource $image , float $size , float $angle , int $x , int $y , int $color , string $fontfile , string $text )
            $image  图像源   $size    字体大小   $angle   逆时针旋转角度   $fontfile  字体类型   $text  文本内容
            </span><span>*/</span><span>
            imagettftext(</span><span>$image</span> , 12 , 0 , 20 , 20 , 0 , <span>$font</span> , <span>$image_caption</span><span>);
        }</span>
登录后复制

　　　　　　　　　7、图片打LOGO

        <span>//</span><span>图片指定位置打LOGO</span>
        <span>if</span>(<span>isset</span>(<span>$_POST</span>['emb_logo'<span>]))
        {
            </span><span>//</span><span>获取水印图片的尺寸并创建水印</span>
            <span>list</span>(<span>$wmk_width</span> , <span>$wmk_height</span>) = <span>getimagesize</span>('images/logo.png'<span>);
            </span><span>//</span><span>$x = ($width-$wmk_width) / 2;
            //$y = ($height-$wmk_height)/2;</span>
            <span>$x</span> = <span>$width</span>-<span>$wmk_width</span><span>;
            </span><span>$y</span> = <span>$height</span>-<span>$wmk_height</span><span>;
            </span><span>$wmk</span> = imagecreatefrompng('images/logo.png'<span>);
            </span><span>//</span><span>把水印图片和原图片合并在一起</span>
            <span>/*</span><span>
            将 wmk 图像中坐标从 0，0 开始，宽度为 $wmk_width，高度为 $wmk_height 的一部分拷贝到 image 图像中坐标为 $x 和 $y 的位置上。
            两图像将根据 pct=20 来决定合并程度，其值范围从 0 到 100。当 pct = 0 时，实际上什么也没做，当为                     
            100 时对于调色板图像本函数和 imagecopy() 完全一样，它对真彩色图像实现了 alpha 透明。
            </span><span>*/</span><span>
            imagecopymerge(</span><span>$image</span> , <span>$wmk</span> , <span>$x</span> , <span>$y</span> , 0 , 0 , <span>$wmk_width</span> , <span>$wmk_height</span> , 20<span>);
            </span><span>//</span><span>清除水印图片</span>
            imagedestroy(<span>$wmk</span><span>);
        }</span>
