What I am basically trying to do is resize a image into two different size images. However I am only being able to resize the first featured_$filename I am not being able to resize thumb_$filename .
Initially I tried creating a single function and passed the configuration as an array and it didnt worked but same thing, only single image was resized.
$this->resizeImage($imagePath, $file['upload_data']['file_name']);
$this->resizeThumb($imagePath, $file['upload_data']['filename']);
public function resizeImage($imagePath, $filename){
$config['image_library'] = 'gd2';
$config['source_image'] = $imagePath;
$config['create_thumb'] = FALSE;
$config['new_image'] = 'featured_'.$filename;
$config['maintain_ratio'] = TRUE;
$config['width'] = 570;
$config['height'] = 372;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
$this->image_lib->clear();
}
public function resizeThumb($imagePath, $filename){
$config['image_library'] = 'gd2';
$config['source_image'] = $imagePath;
$config['create_thumb'] = FALSE;
$config['new_image'] = 'thumb_'.$filename;
$config['maintain_ratio'] = TRUE;
$config['width'] = 180;
$config['height'] = 135;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
$this->image_lib->clear();
}
You need to load the library only once but initialize the library twice with different configs. E.g. :
$this->load->library('image_lib');
/* size 64*72 for comments */
$configThumb = array();
$configThumb['image_library'] = 'gd2';
$configThumb['create_thumb'] = TRUE;
$configThumb['new_image'] = './profile_images/thumbs/';
$configThumb['maintain_ratio'] = TRUE;
$configThumb['width'] = 64;
$configThumb['height'] = 72;
$configThumb['thumb_marker'] = "";
//$this->load->library('image_lib');
/* size 64*72 for comments */
/* size 167*167 for profile page */
$configThumbMedium = array();
$configThumbMedium['image_library'] = 'gd2';
$configThumbMedium['create_thumb'] = TRUE;
$configThumbMedium['new_image'] = './profile_images/medium/';
$configThumbMedium['maintain_ratio'] = TRUE;
$configThumbMedium['width'] = 167;
$configThumbMedium['height'] = 167;
$configThumbMedium['thumb_marker'] = "";
/* size 167*167 for profile page */
if(!$this->upload->do_upload('image')){
return 0;
}
$uploadedDetails = $this->upload->data();
if($uploadedDetails['is_image'] == 1){
$this->image_lib->initialize($configThumb);
$this->image_lib->resize();
$this->image_lib->initialize($configThumbMedium);
$this->image_lib->resize();
}
Hope it helps.
hi load library first and use $this->image_lib->initialize($config) to pass config and also in new_image config pass path with new image name.
$this->load->library('image_lib');
$config['new_image'] = 'image_dir/thumb_'.$filename
//ALL your other configs
$this->image_lib->initialize($config)

Here is my code from controller
`
$type= explode('.', $_FILES['picture']['name']);
$type = $type[count($type)-1];
$url = "uploads/products/images/".uniqid(rand()).".".$type;
if(in_array($type, array('jpg','jpeg','png','JPG','JPGE','PNG') ) )
{
if(is_uploaded_file($_FILES['picture']['tmp_name']))
{
move_uploaded_file($_FILES['picture']['tmp_name'],$url);
}
}

Since you're using CodeIgniter, it has it's own Image Manipulation class:
https://www.codeigniter.com/userguide3/libraries/image_lib.html
$config['image_library'] = 'gd2';
$config['source_image'] = '/path/to/image/mypic.jpg';
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 75;
$config['height'] = 50;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
Set the width and height variables to what you need to resize the image to.
This is the code which I am trying to run..
I have stored the image in images folder whose path is: C:\xampp\htdocs\ci\images, and is at the same level at that of the application folder
public function display(){
$config['image_library'] = 'gd2';
$config['source_image'] = '/images/mypic.jpg';
$config['new_image']='/images/re_mypic.jpg';
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 75;
$config['height'] = 50;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
I am not getting any error or something
Add this and check your code errors
if ( ! $this->image_lib->resize()) {
echo $this->image_lib->display_errors();
}
okay, so I have two separate configs for the same library in the same controller function. The first one runs just fine, but the second does not. How can I make it so codeigniter unsets the first one and uses the second config.
// Retrieve the data from the upload
$data = $this->upload->data();
//Re-size the large image and re-save it
$config['image_library'] = 'gd2';
$config['source_image'] = $this->config->item('upload_path').''.$this->aauth->get_user_id().'/'.$file_name.''.$data['file_ext'];
$config['new_image'] = $this->config->item('upload_path').''.$this->aauth->get_user_id().'/';
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['master_dim'] = 'auto';
$config['width'] = 600;
$config['height'] = 516;
$this->load->library('image_lib', $config);
if ( ! $this->image_lib->resize())
{
echo $this->image_lib->display_errors();
}
else
{
$this->image_lib->crop();
echo 'Image Resized!';
}
//Create a thumbnail for the image
$config['image_library'] = 'gd2';
$config['source_image'] = $this->config->item('upload_path').''.$this->aauth->get_user_id().'/'.$file_name.''.$data['file_ext'];
$config['new_image'] = $this->config->item('upload_path').''.$this->aauth->get_user_id().'/thumbnails/';
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 120;
$config['height'] = 120;
$this->load->library('image_lib', $config);
if ( ! $this->image_lib->resize())
{
echo $this->image_lib->display_errors();
}
else
{
echo 'Image Thumbnail Created!';
}
So it re-sizes the image and then is supposed to thumbnail an image.
You can use the initialize method provided by the library, so you call it instead of loading the library each time:
$this->load->library('image_lib');
$config['image_library'] = 'gd2';
$config['source_image'] = $this->config->item('upload_path').''.$this->aauth->get_user_id().'/'.$file_name.''.$data['file_ext'];
$config['new_image'] = $this->config->item('upload_path').''.$this->aauth->get_user_id().'/';
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['master_dim'] = 'auto';
$config['width'] = 600;
$config['height'] = 516;
$this->image_lib->initialize($config);
....
$config['image_library'] = 'gd2';
$config['source_image'] = $this->config->item('upload_path').''.$this->aauth->get_user_id().'/'.$file_name.''.$data['file_ext'];
$config['new_image'] = $this->config->item('upload_path').''.$this->aauth->get_user_id().'/thumbnails/';
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 120;
$config['height'] = 120;
$this->image_lib->initialize($config);
I am using following code but unable to resize image even $this->image_lib->resize() is returning true, don't know what is going wrong:
if(file_exists($_SERVER['DOCUMENT_ROOT']."/uploads/avatars/".str_replace('_','-',$image)))
{
$config['source_image'] = $_SERVER['DOCUMENT_ROOT']."/uploads/avatars/".str_replace('_','-',$image);
}
else if (!file_exists("./uploads/avatars/".$image) || $image=="")
{
$config['source_image'] = $_SERVER['DOCUMENT_ROOT'].'/uploads/avatars/photo.jpg';
}
else
{
$config['source_image'] = $_SERVER['DOCUMENT_ROOT']."/uploads/avatars/".$image;
}
$config['image_library'] = 'gd2';
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['dynamic_output'] = TRUE;
$config['width'] = $width;
$config['height'] = $height;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
Try the new_image tag:
$config['new_image'] = '/path/to/new_image.jpg';
Better to use SimpleImage.php as helper in CodeIgniter
$source=base_url().'/uploads/avatars/photo.jpg';
$image = new SimpleImage();
$image->load($source);
$image->resize(600,400);
$image->save($name_and_location);
I have created a library file that manages gallery functions, when a user uploads an image.
This code will not create a thumbnail - it tries to resize the original image - am i missing something obvious?
private function _create_thumbnail($file_path)
{
$config['image_library'] = 'gd2';
$config['source_image'] = $file_path;
$config['create_thumb'] = 1;
$config['maintain_ratio'] = 1;
$config['width'] = 90;
$config['height'] = 90;
$this->CI->load->library('image_lib', $config);
$this->CI->image_lib->initialize($config);
$result = $this->CI->image_lib->resize();
print_r( $this->CI->image_lib->display_errors());
print_r($config);
// if(!$result) {
// // echo $this->CI->image_lib->display_errors();
// print_r($this->CI->image_lib->display_errors());
// }
return $result;
}
Remove the below line and try again
$this->CI->image_lib->initialize($config);
