Generated Portrait Placeholders

Today, I finished a script that generates thumbnail-sized images. The images are just solid fills of the web-safe colors. These images will be used as placeholders so that I can begin developing the MG game. I'll be able to work out the kinks of the game this way. Right now, the script creates PNGs, but I can easily change it to create JPGs.


The script used a Pear library called Image_Canvas. Here is the script, called gen_profile_images.php:

<?php
    // profile pic gen
    require_once "../include.php"; // pear path
    require_once "Image/Canvas.php"; 
    require_once "Image/Canvas/GD.php";
    require_once "Image/Canvas/GD/PNG.php";

    
    
    echo "test";
    
    $possible = str_split("123456789ABCDEF");
    $pairs = array();
    foreach ( $possible as $chr ) {
        
        $pairs [] = "$chr$chr";
        
    }
    
    $colors = array();
    for ( $i = 0 ; $i < count($pairs); $i++ ) {
        for ( $j = 0 ; $j < count($pairs); $j++ ) {
            for ( $k = 0 ; $k < count($pairs); $k++ ) {
                $colors[] = "{$pairs[$i]}{$pairs[$j]}{$pairs[$k]}";
            }
        }
    }
    echo "generated ".count($colors)." colors";
    
    
    foreach ( $colors as $color ) {
        $width = 100;
        $height = 150;
        $fillColor = "#$color";
        $fn = "$color.png";
        
        $canvas = new Image_Canvas_GD_PNG( 
            array ( 
                "width"     =>$width,
                "height"    =>$height,
                "left"      =>0,
                "top"       =>0)
            );

        $canvas->rectangle ( 
            array (
                "x0" => 0,
                "y0" => 0,
                "x1" => $width,
                "y1" => $height,
                "fill" => $fillColor)
            );
        
        $canvas->save ( array( "filename" => "images/$fn" ));    
        //echo "Saved image $fn";
    }
?>
