imagecreatefromjpeg、imagecreatefromgif、imagecreatefrompng、getimagesize、imagecreatetruecolor、imagecopyresampled、imagejpeg...> 九、imagejpeg函数 imagejpeg函数，将图像输出到浏览器或文件。PHP版本支持4.0+，使用方式： <?...php // 参数注释：图像资源，路径，质量（默认值（-1）使用默认的IJG质量值（约75）） imagejpeg($tmp, $directory . $filename, 100); ?...is_dir($directory)) { if(is_writable($directory)) { imagejpeg

保存裁剪后的图片，例如：imagejpeg($cropped_image, '..../uploads/test_crop.jpg');在上述代码中，我们使用 imagejpeg() 函数将裁剪后的图片保存到指定路径下，也可以使用 imagepng() 或 imagegif() 函数保存
imagecopyresized($imNew, $im, 0, 0, 0, 0, $w / 2, $h / 2, $w, $h); header("Content-type: image/jpg"); imagejpeg...imagecopyresized($imNew, $im, 0, 0, 0, 0, $w / 2, $h / 2, $w, $h); header("Content-type: image/jpg"); imagejpeg...($imNew, null, 10); imagedestroy($imNew); 也就是 imagejpeg() 函数的最后一个参数，就和 PS 导出图片时的压缩比率一样，如果数字越小，压缩比越高，...imagecopyresized($imNew, $im, $sX + 2, $sY + 1, 0, 0, $sW, $sH, $w, $h); header("Content-type: image/jpg"); imagejpeg...($im) - 150 - 10, imagesy($im) - 60 - 10, 0, 0, 150, 30, 50); } header("Content-type: image/jpg"); imagejpeg
]) { case 1: //imagegif($nimage, $destination); imagejpeg...($nimage, $destination); break; case 2: imagejpeg($nimage,...break; case 6: imagewbmp($nimage, $destination); //imagejpeg
0, $this->resize_width,$this->resize_height, (($this->height)*$resize_ratio), $this->height); ImageJpeg...0, $this->resize_width, $this->resize_height, $this->width, (($this->width)/$resize_ratio)); ImageJpeg...im, 0, 0, 0, 0, $this->resize_width, ($this->resize_width)/$ratio, $this->width, $this->height); ImageJpeg..., 0, 0, 0, ($this->resize_height)*$ratio, $this->resize_height, $this->width, $this->height); ImageJpeg
imagecopyresized($dst_im, $src_im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height); imagejpeg...); // var_dump($imgs);exit; // header("Content-type: image/jpeg"); imagejpeg
} if($img_info[2]==3){ imagepng($im,$savePath); }else{ imagejpeg...到这里，其实直接用imagecopymerge结合imagepng或imagejpeg图片水印就基本加上去了。 可是我们需要将水印铺满整张图片，单纯一个那不得调用很多次函数？
