can someone help me calculate and crop the center of the image ?:
Code: function image_crop($sourceHeight, $sourceWidth, $image){
$target_path = FCPATH.'pictures/cropped/';
$targetHeight = '214';
$targetWidth = '171';
$centreX = round($sourceWidth / 2);
$centreY = round($sourceHeight / 2);
$cropWidth = round($targetWidth /2);
$cropHeight = round($targetHeight / 2);
$config = array( 'image_library' => 'gd2',
'source_image' => $image,
'new_image' => $target_path,
'create_thumb' => TRUE,
'thumb_marker' => '',
'x_axis' => $x,
'y_axis' => $y
);
$this->image_lib->initialize($config);
if($this->image_lib->crop()){
return true;
}
else{
return false;
}
}//end of image_crop function

This is untested, but might work.
Code: <?php
function image_crop($image, $targetWidth = '200', $targetHeight = '200')
{
$imageInfo = getimagesize($image);
$config = array(
'image_library' => 'gd2',
'width' => $targetWidth,
'height' => $targetHeight,
'source_image' => $image,
'new_image' => FCPATH.'pictures/cropped/'.pathinfo($image, PATHINFO_FILENAME),
'x_axis' => ($targetWidth < $imageInfo[0])
? round(($imageInfo[0] - $targetWidth) / 2)
: 0,
'y_axis' => ($targetHeight < $imageInfo[1])
? round(($imageInfo[1] - $targetHeight) / 2)
: 0,
);
$this->image_lib->initialize($config);
if($this->image_lib->crop()) {
return true;
} else {
return false;
}
}//end of image_crop function

cropping works fine...however i should resize first and then cropp...
how can i combine this two methods to resize and crop on the fly....
Code: function image_resize($image){
$target_path = FCPATH.'uploads/profile_pictures/171x214/';
$config = array( 'image_library' => 'gd2',
'source_image' => $image,
'new_image' => $target_path,
'maintain_ratio' => TRUE,
'create_thumb' => TRUE,
'thumb_marker' => '',
'width' => 171,
'height' => 214
);
$this->image_lib->initialize($config);
if($this->image_lib->resize()){
return true;
}
else{
return false;
}
}//end of image_resize function
Code: function image_crop($image){
$imageInfo = getimagesize($image);
$target_path = FCPATH.'uploads/profile_pictures/135x135_crop/';
$targetHeight = 135;
$targetWidth = 135;
//$imageInfo[0] = image width
$x = ($targetWidth < $imageInfo[0]) ? round(($imageInfo[0] - $targetWidth) / 2) : 0;
//$imageInfo[1] = image height
$y = ($targetHeight < $imageInfo[1]) ? round(($imageInfo[1] - $targetHeight) / 2) : 0;
$c 'image_library' => 'gd2',
'source_image' => $image,
'new_image' => $target_path,
'create_thumb' => TRUE,
'thumb_marker' => '',
'x_axis' => $x,
'y_axis' => $y
);
$this->image_lib->initialize($config);
if($this->image_lib->crop()){
return true;
}

return false;

Why do you need to resize and then crop? Normally we only need to do one or the other.

because when it crops large images...it crops only the center of it without resize..
ex...if i crop a large profile picture, it crops only the nose ...

I see. So you want to resize the image, and then crop it to previously determined dimensions? That makes sense.
I don't see why you're having a problem. Calling both of those methods should work how you want it to. You just need to make sure you're cropping the image in-place. It might make more sense to do it all in a temporary directory and then move the end product to the final directory.

actually i want to resize the picture using resize_image() function and store to a directory....and i do that...it works fine but than i wan to do a crop of that image and store the cropped image to a different directory
here is the controller i use to resize :
Code: function validate_edit_profile(){
$user_id = $this->uri->segment(3) ? $this->uri->segment(3) : 0;
$picture = 'profile_pic';
$user = $this->users_model->select_user_by_id($user_id);
$pic_name = $user->profile_pic;
if($_FILES[$picture]['name'] && $_FILES[$picture]['size'] > 0 ){
$picture_path = FCPATH.'uploads/profile_pictures/original/'.$pic_name;
$thumb_path = FCPATH.'uploads/profile_pictures/171x214/'.$pic_name;
unlink($picture_path);
unlink($thumb_path);
$config['upload_path'] = FCPATH.'uploads/profile_pictures/original/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
//when you change this, the upload_max_filesize in php.ini file must be changed too
$config['max_size'] = '2000';
$config['remove_spaces'] = TRUE;
$this->load->library('upload', $config);
if($this->upload->do_upload($picture)){ //if upload of picture is successfull
$data = $this->upload->data(); //get all the uploads file data(name, path...)
$image = $data['full_path'];
$this->load->model('images_model'); //load images_model
if ($this->images_model->image_resize($image) == TRUE) {
$profile_pic_name = $data['file_name']; //get the name of the picture
}
}
}
}

Why can't you figure that out yourself? People have written examples for you, but you need to understand what's happening. We can't keep writing your code for you.
