Cannot resize, then watermark the same image in CodeIgniter - El Forum - 03-21-2014
[eluser]therealjerdev[/eluser]
When I try doing multiple things, say resize, then watermark the same image. Only the first process [resizing] works, but the second does not.
here is my code, I factored out the manipulation into a new library.
my controller:
Code:
function upload()
{
// start jpegcam code
$username = $this->session->userdata('username');
if (!file_exists(APPPATH . '../images/' . $username . '/'))
{
mkdir(APPPATH . '../images/' . $username . '/', 0777, true);
}
$folder = APPPATH . '../images/' . $username . '/';
$filename = $this->session->userdata('username') . date("-Ymd") . '.jpg';
$input_con = file_get_contents("php://input");
$image_data = $folder.$filename;
file_put_contents($image_data, $input_con);
//end jpegcam code
/* Start image manipulation
* Start resizing to 640px x 480px
*/
$this->load->library('manipulate_img');
$this->manipulate_img->resize($image_data);
/*
* Start watermarking date/time and logo
*/
$this->manipulate_img->watermark($image_data);
//if (isset($_POST))
// $this->Gallery_model->do_upload();
}my library:
Code:
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class Manipulate_img
{
function __construct()
{
$this->CI =& get_instance();
$this->CI->load->library('image_lib');
}
public function resize($pic_path)
{
/*
* Start resizing to 640px x 480px
*/
$config['source_image'] = $pic_path;
$config['maintain_ratio'] = TRUE;
$config['width'] = 640;
$config['height'] = 480;
$this->CI->image_lib->initialize($config);
$this->CI->image_lib->resize();
$this->CI->image_lib->clear();
return true;
}
public function watermark($pic_path)
{
$config['source_image'] = $pic_path;
$config['wm_text'] = date("F m Y // ") . $this->session->userdata('username') . ' // www.InterJo.in';
$this->CI->image_lib->initialize($config);
$this->CI->image_lib->watermark();
$this->CI->image_lib->clear();
return true;
}
}I just can't get why it wont run multiple manipulation processes on the same image, one after the other...

I think there is no font information given. So even though watermark is made there will no text overlayed. Below is the example of font configuration.
Code:
$config['wm_font_path'] = './system/fonts/texb.ttf';
$config['wm_font_size'] = '16';
$config['wm_font_color'] = 'ffffff';
$config['wm_vrt_alignment'] = 'bottom';
$config['wm_hor_alignment'] = 'center';
$config['wm_padding'] = '20';Cannot resize, then watermark the same image in CodeIgniter - El Forum - 03-22-2014

Hmm, those configs should be already defaulted if not defined by me.
But anyways, I tried it anyways and it still wont work.
My code seems pretty logical to you right? Can't seem to see why it won't work out.. :/
My thinking is that the second process [watermarking] gets executed before the last one was fully saved to disk, but that shouldn't be the case because php should wait for a return [true] from the resize method called. and since it does, the image should have already been saved to disk.. which in turn would go to the next 'watermarking'...

Wow, weird, anyways, all I had to do was watermark it first, and THEN resize it. I couldn't do it the other way around which was weird...
I also had to change, within the watermark function in my Manipulate_img class,
Code:
$this->session->userdata('username')Code:
$this->CI->session->userdata('username')
