收藏一下资源: 一、创建图片资源 imagecreatetruecolor(width,height); imagecreatefromgif(图片名称); imagecreatefrompng(图片名称...0.3; list($width, $height)=getimagesize($filename); $n_w=$width*$per; $n_h=$width*$per; $new=imagecreatetruecolor...{ $width = ($height / $s_h) * $s_w; } else { $height = ($width / $s_w) * $s_h; } $new=imagecreatetruecolor...{ $width = ($height / $s_h) * $s_w; } else { $height = ($width / $s_w) * $s_h; } $new=imagecreatetruecolor...php //step 1创建图片资源 $img=imagecreatetruecolor(200,200); $red=imagecolorallocate($img,255,0,0); $yellow
$width * $percent; $newheight = $height * $percent; $src_im = imagecreatefromjpeg($file); $dst_im = imagecreatetruecolor...case 1: $giftype=check_gifcartoon($imgsrc); if($giftype){ header('Content-Type:image/gif'); $image_wp=imagecreatetruecolor...$imgdst,75); imagedestroy($image_wp); } break; case 2: header('Content-Type:image/jpeg'); $image_wp=imagecreatetruecolor...image_wp, $imgdst,75); imagedestroy($image_wp); break; case 3: header('Content-Type:image/png'); $image_wp=imagecreatetruecolor
GD库 图片处理的典型流程 1:造画布(或读入一幅图作画布) 2:造颜料 3:利用颜料在画布上写字或填充颜色或画形状 4:输出/生成图片 5:销毁画布 1、GD库 之生成验证码 创建画布(imagecreatetruecolor...imagestring) 形成图片(image[jpeg|png|gif]) 销毁画布(imagedestroy) 2、GD库 之生成缩略图 读取图片,形成资源(imagecreatefrom***) 创建缩略画布(imagecreatetruecolor...imagecreatefrom***) 读取水印图片,(同上) 复制图片资源(imagecopymerge) 形成图片(image[jpeg|png|gif]) 销毁画布(imagedestroy) //创建画布 $im = imagecreatetruecolor.../first.png') //------------------------------------------------------- //创建x像素宽,y像素高的图片资源 resource imagecreatetruecolor
info['mime']){ case 'image/jpeg': header('Content-Type:image/jpeg'); $image_wp = imagecreatetruecolor...break; case 'image/png': header('Content-Type:image/png'); $image_wp = imagecreatetruecolor...break; case 'image/gif': header('Content-Type:image/gif'); $image_wp = imagecreatetruecolor
,主要是一下图像处理函数: strtolower、end、imagecreatefromjpeg、imagecreatefromgif、imagecreatefrompng、getimagesize、imagecreatetruecolor...> 七、imagecreatetruecolor函数 imagecreatetruecolor函数,新建一个真彩色图像,成功后返回图象资源,失败后返回 FALSE 。使用方式: <?...php $tmp = imagecreatetruecolor($width, $height); ?...]; $newHeight = $postVars["image_dimensions"]; $tmp = imagecreatetruecolor
($giftype) { header('Content-Type:image/gif'); $image_wp = imagecreatetruecolor...case 2: header('Content-Type:image/jpeg'); $image_wp = imagecreatetruecolor...; case 3: header('Content-Type:image/png'); $image_wp = imagecreatetruecolor
ftoH = $toH; } if ($srcW > $toW || $srcH > $toH) { if (function_exists("imagecreatetruecolor...")) { @$ni = imagecreatetruecolor($ftoW, $ftoH); if ($ni) {..., 0, 0, $ftoW, $ftoH, $srcW, $srcH); } //裁剪图片成标准缩略图 $new_imgx = imagecreatetruecolor
newheight = $height * $percent; $src_im = imagecreatefromjpeg($file); $dst_im = imagecreatetruecolor...png'; $src = imagecreatefromstring(file_get_contents($original_path)); $newpic = imagecreatetruecolor...().'.jpg'; list($max_width, $max_height) = getimagesize($imgs['dst']); $dests = imagecreatetruecolor
下面是一个使用imagecopy函数复制图像的示例代码: $srcImg = imagecreatefromjpeg('image.jpg'); $dstImg = imagecreatetruecolor...0, 0, 0, 0, imagesx($srcImg), imagesy($srcImg)); 在上面的代码中,我们首先使用imagecreatefromjpeg函数创建了一个源图像,并使用imagecreatetruecolor...下面是一个使用imagecopyresampled函数复制图像的示例代码: $srcImg = imagecreatefromjpeg('image.jpg'); $dstImg = imagecreatetruecolor...下面是一个使用块复制技巧优化图像复制过程的示例代码: $srcImg = imagecreatefromjpeg('image.jpg'); $dstImg = imagecreatetruecolor
