Anyone knows how output de dinamic_save?

Between another thing, i try this:

<img alt='$label'>image_moo->load($image_path)->resize(100,100)->save_dynamic()."'>

but dont work..

You can’t do that I’m afraid (Well pretty sure). You will need a callback to your controller that sends the output back e.g. \controlle\sized\image_name and that will output image headers and the resized image.

Thx the reply Mat!

So, always when i want to use the dynamic_save i need use somethink like ajax to load the images?

Thx again, see ya

Don’t need ajax jsut “/mycontroller/imagefunction/image_path” although you would have to convert the filepath to something more browser friendly! If you can it’s better to cache the resized image and just serve it direct, that wa the cpu only has to size it once and saves time (disk is cheap!)

Great library! =)
I noticed that it doesn’t support the resize of transparent PNG images at the time so for those who are interested in this, open image_moo.php and look for ( line 552 ):

// if padding, fill background
if ($pad)
{
     $col = $this->_html2rgb($this->background_colour);
     $bg = imagecolorallocate($this->temp_image, $col[0], $col[1], $col[2]);
     imagefilledrectangle($this->temp_image, 0, 0, $tx, $ty, $bg);
}

Add the following below:

imagealphablending($this->temp_image, false);
imagesavealpha($this->temp_image, true);
$color = imagecolorallocatealpha($this->temp_image, 0, 0, 0, 127);
imagefilledrectangle($this->temp_image, 0, 0, $this->width, $this->height, $color);

That should do it! 😊

Kind regards,

Where should this be added? after the pad code? I need ot work on keeping transparency data!

OMG, auhauha, i probably see now, in the image tag put the image_resize uri (controller/func_resizer/image_path)

To image_path i use:

public function setSpecialChar($string){
    return str_replace( '=', '', base64_encode( ($string) ) );
}
public function getSpecialChar($string){
    return utf8_decode( base64_decode($string) );
}

Thx again for all help!

humm, CI have someway to cache this? for now i dont want create another file..

“Warning: Because of the way CodeIgniter stores content for output, caching will only work if you are generating display for your controller with a view.”

Damn it!

Caching would write another file anyway 😊

Amazing library, thanks.

Can we use URL for load?

Not sure, why don’t you try it and let us know.

It doesn’t works with URL but i fixed. Hope this helps 😊
Now you can use local image or remote URL for manipulating. 😉

Download:
http://pastebin.com/raw.php?i=hTwccqHg

Usage:

$this->load->library('image_moo');
    $this->image_moo
        ->load("http://somewebsite.com/someimage.jpg")
        ->resize(200,200)
        ->save("thumb.x");
    if ($this->image_moo->error) print $this->image_moo->display_errors();

CHANGED: _load_image() function
ADDED: _check_url() function

The code goes inside the pad block.
But this line:

imagefilledrectangle($this->temp_image, 0, 0, $this->width, $this->height, $color);

Should be changed to:

imagefilledrectangle($this->temp_image, 0, 0, $tx, $ty, $color);

That’s how I made it work

When I display a png image with save_dynamic

if the orignal file background is transparent
its show in black when I display it

someone know how to fix it?

Cool lib! many thanks quite an ideal offer for sharing

Hello i changed the method resize to fill with transparent background just in “$pad=true” case.

//near of line 553…
   //if padding, fill background…

        if ($pad)
        {
            $col = $this->_html2rgb($this->background_colour);
            
            if($this->background_colour != ""){
                $bg = imagecolorallocate($this->temp_image, $col[0], $col[1], $col[2]);
                imagefilledrectangle($this->temp_image, 0, 0, $tx, $ty, $bg);
            }else{
                imagecolortransparent ( $this->temp_image ,  imagecolorallocate($this->temp_image, $col[0], $col[1], $col[2]) );
            }
        }

Now you can do this:

$this->image_moo
    ->load('DSC01707.JPG')
    ->set_background_colour("#TRANSPARENT")
    ->resize(100,100,TRUE)
    ->save("sarasa.png"); //remember save to png

what do you think?

set_background_color will fail with that. I’ve got to do some further work to improve transparency, but I have got

if ($pad)
        {
            $col = $this->_html2rgb($this->background_colour);
            $bg = imagecolorallocate($this->temp_image, $col[0], $col[1], $col[2]);
            imagefilledrectangle($this->temp_image, 0, 0, $tx, $ty, $bg);
            /* TO DO
            imagealphablending($this->temp_image, false);
            imagesavealpha($this->temp_image, true);
            $color = imagecolorallocatealpha($this->temp_image, 0, 0, 0, 127);
            imagefilledrectangle($this->temp_image, 0, 0, $this->width, $this->height, $color);
            */
        }

That might help, can’t remember if it does anything! When I get a spare 5 mins (maybe in 2020) I will do some further work on it!
