I'm trying to turn my image sepia (third function in above URL)

PHP Code:

function sepia($tintR = 80,$tintG = 43,$tingB = -23,$rateR = .229,$rateG = .587,$rateB = .114,$whiteness = 3) 

        { 



                for ($x = 0; $x < $this->numColors; $x++) 

                { 

                        $src_colors     = imagecolorsforindex($this->resource_image,$x); 

                        $new_color      = min(255,abs($src_colors["red"] * $rateR + $src_colors["green"] * $rateG + $src_colors["blue"] * $rateB) + $whiteness); 

                        $r              = min(255,$new_color + $tintR); 

                        $g              = min(255,$new_color + $tintG); 

                        $b              = min(255,$new_color + $tintB); 

                        imagecolorset($this->resource_image,$x,$r,$g,$b); 

                } 

        } 

I dont know how to call this function. would i do sepia($imagesrc) ?

I appreciate any help.

My guess is you call it by doing: -

serpia();

And dont specify any arguements.

thanks for the reply, but how do i tell it what image im inputting?

As it's part of a class called "imageFiltersIndex", you'd call it one of two ways:

PHP Code:

<?php



$imageFiltersIndex = new imageFiltersIndex();

$imageFiltersIndex->sepia();



?>

...or:

PHP Code:

<?php



imageFiltersIndex::sepia();



?>

...after including the class, of course.

It tells you exactly how to do that in the very page you linked to.

From (*gasp*) http://www.zend.com/codex.php?id=1101&single=1

Code:

  * Usage: 
  * 
  *     $img_src                = ImageCreateFromJpeg("image.jpg"); 
  *     $imageFiltersIndex      = new imageFiltersIndex; 
  *     $imageFiltersIndex->resource($img_src); 
  *     $imageFiltersIndex->filter([$options1],[$options2,...]); 
  * 
  *  Where filter is the filter name and $options is a filter option. 
  *  All imageFilterIndex should have some defaults filters options, so you do not need to 
  *     use options if you do not want to. 
  * 
  * 
  * Example: 
  * 
  * $img_src_file = "file.jpg"; 
  * 
  * $img_src=ImageCreateFromJpeg($img_src_file); 
  * 
  * $imageFiltersIndex = new imageFiltersIndex; 
  * $imageFiltersIndex->resource($img_src); 
  * $imageFiltersIndex->sepia(); 
  * 
  * header("Content-type: image/jpeg"); 
  * imagejpeg($img_src,"",50);

can't believe i missed it.

PHP Code:

 $img_src                = ImageCreateFromJpeg("image.jpg"); 

thanks for all the replies.
