php图片是啥,php图片处理类(附实例)
分享一個(gè)php實(shí)現(xiàn)的圖片處理類，可以設(shè)置文字水印與圖片水印等，有需要的朋友參考下。
本節(jié)分享一個(gè)圖片處理類，簡單實(shí)現(xiàn)了文字水印與圖片水印，是學(xué)習(xí)php圖片操作的小例子。
代碼：
image = new Imagick($tplImage);
}
/**
* 設(shè)置文本屬性
*
* @param string $sText text to print on the image (i.e. Buy 1 Get 1 Free )
* @param integer $x text to print from x codinates
* @param integer $y text to print from y codinates
* @param integer $font text size for printing
* @param string $color text color for print
* @param integer $text_anglerotate text from 0-360
* @param string $font_style installed font name and path (i.e /usr/share/fonts/liberation/LiberationSans-Italic.ttf)
* @Creating an array of text properties
*/
public function setText($sText, $x = 0, $y = 0, $font = 12, $color = 'black', $text_angle = 0, $font_style = './LiberationSans-Italic.ttf') {
$this->aTextData[] = array("text"=>$sText, "font_color"=>$color, "font_size"=>$font,"x"=>$x,"y"=>$y, "font_style"=>$font_style,
"text_angle"=>$text_angle);
}
/**
* 設(shè)置圖片屬性
*
* @param string $sImage text to print on the image (i.e. /home/httpd/images/brand.jpg )
* @param integer $x text to print from x codinates
* @param integer $y text to print from y codinates
* @param integer $text_anglerotate text from 0-180
* @Creating an array of image properties
*/
public function setImage($sImage, $x = 0, $y = 0, $angle=0) {
$this->aImageData[] = array("image"=>$sImage, "x"=>$x, "y"=>$y, "angle"=>$angle);
}
/**
* 從文字和圖片屬性生成最終圖像
*
* @param string $sImage Output image Name
* @return boolean returns TRUE on success and FALSE upon failure
*/
public function generateImage($sImage) {
foreach ($this->aImageData as $aImageValue) {
if (!trim($aImageValue["image"])) {
$sError = 1;
break;
}
$oImg = new Imagick($aImageValue["image"]);
$oImg->rotateImage("transparent", $aImageValue["angle"]);
$this->image->compositeImage($oImg, $oImg->getImageCompose(), $aImageValue["x"], $aImageValue["y"]);
unset($oImg);
}
foreach ($this->aTextData as $aTextValue){
if (!trim($aTextValue['text'])) {
$sError = 2;
break;
}
$oDraw = new ImagickDraw();
$oDraw->setFont($aTextValue['font_style']);
$oDraw->setFontSize($aTextValue['font_size']);
$oDraw->setFillColor($aTextValue['font_color']);
$this->image->annotateImage($oDraw, $aTextValue['x'], $aTextValue['y'], $aTextValue['text_angle'], $aTextValue['text']);
unset($oDraw);
}
if ($sError == 1) {
exit("Unable to generate Image. Check \"setImage\" Properties");
}elseif ($sError == 2) {
exit("Unable to generate Image. Check \"setText\" Properties");
}
$this->image->setImageFormat("jpg");
return $this->image->writeImage($sImage);
}
}
?>
2，調(diào)用示例：
setText("This is one", 350, 20, 22, "red");
$oImageMagick->setText("This is Two", 50, 50, 25, "blue","50");
$oImageMagick->setImage("brand.jpg", 160, 90, 0);
$oImageMagick->setImage("tata.jpg", 160, 20);
$newImagename = "mynewImage.jpg";
$oImageMagick->generateImage($newImagename);
?>
