I am working on aan image manipulation class for a project to re-size uploaded slider images to 780 X 397 and uploaded avartaravatar pictures to 220 X 220. I am wondering if this is a good way to construct it.
A question I have is whatWhat would be the best way to handle an image that is smaller then 780 X 397. Should I simply re-size it or go about it a different way?
HaveI have included the class code as well as the code syntax on how it is to be used:
class imageEditer{
private $filename;
public $picWidth;
public $picHeight;
public $picMimeType;
public $picMimeTypeCons;
private $allowedMimeType = array(IMAGETYPE_GIF=>'.gif',IMAGETYPE_JPEG=>'.jpg',IMAGETYPE_PNG=>'.png',IMAGETYPE_BMP=>'.bmp');
public $picture;
private $imageWork;
private $storePath;
public function __construct($filename){
if(is_file($filename)){
$this->filename = $filename;
$getimagesize = getimagesize($this->filename);
$this->picWidth = $getimagesize[0];
$this->picHeight = $getimagesize[1];
$this->picMimeTypeCons = $getimagesize[2];
if($this->allowedMime()){
$this->picMimeType = image_type_to_mime_type($this->picMimeTypeCons);
$this->picture = $this->imageCreate($this->picMimeTypeCons);
}else{
trigger_error('Mime type not allowed',E_USER_ERROR);
}
}else{
trigger_error('File not found',E_USER_ERROR);
}
}
public function imageCreate($mimeTypeCons){
switch ($mimeTypeCons) {
case IMAGETYPE_GIF:
return imagecreatefromgif($this->filename);
break;
case IMAGETYPE_JPEG:
return imagecreatefromjpeg($this->filename);
break;
case IMAGETYPE_PNG:
return imagecreatefrompng($this->filename);
break;
case IMAGETYPE_BMP:
return imagecreatefromwbmp($this->filename);
break;
default:
trigger_error("Couldn't create image.",E_USER_ERROR);
break;
}
}
public function imageCreateSlider($storePath,$width = 780,$height = 397){
$this->storePath = $storePath;
$divWidth = floor(($this->picWidth-$width)/2) ;
$divHeight = floor(($this->picHeight-$height)/2);
$this->imageWork = imagecrop($this->picture,array("x"=>$divWidth,"y"=>$divHeight,"width"=>$width,"height"=>$height));
if(strstr(basename($this->storePath),'.') != strstr(basename($this->filename),'.')){
while ($fileEx = current($this->allowedMimeType)) {
if(strstr(basename($this->storePath),'.') == $fileEx){
$this->imageCreateType(key($this->allowedMimeType));
return;
}
next($this->allowedMimeType);
}
}else{
$this->imageCreateType($this->picMimeTypeCons);
}
}
public function imageAvatar($storePath,$width = 220,$height = 220){
$this->storePath = $storePath;
$this->imageWork = imagescale($this->picture,$width,$height);
if(strstr(basename($this->storePath),'.') != strstr(basename($this->filename),'.')){
while ($fileEx = current($this->allowedMimeType)) {
if(strstr(basename($this->storePath),'.') == $fileEx){
$this->imageCreateType(key($this->allowedMimeType));
return;
}
next($this->allowedMimeType);
}
}else{
$this->imageCreateType($this->picMimeTypeCons);
}
}
public function imageCreateType($mimeTypeCons){
switch ($mimeTypeCons) {
case IMAGETYPE_GIF:
return imagegif($this->imageWork,$this->storePath);
break;
case IMAGETYPE_JPEG:
return imagejpeg($this->imageWork,$this->storePath);
break;
case IMAGETYPE_PNG:
return imagepng($this->imageWork,$this->storePath,9,PNG_ALL_FILTERS);
break;
case IMAGETYPE_BMP:
return image2wbmp($this->imageWork,$this->storePath);
break;
default:
trigger_error("Couldn't create image.",E_USER_ERROR);
break;
}
}
public function allowedMime(){
for ($i=0; $i <count($this->allowedMimeType) ; $i++) {
return array_key_exists($this->picMimeTypeCons,$this->allowedMimeType);
}
}
public function __destruct(){
imagedestroy($this->picture);
if(!empty($this->imageWork)) imagedestroy($this->imageWork);
}
}
Any suggestion are appreciated.
