PHP生成ICO图标使用phpthumb_ico类完整实例，icophpthumb_ico

这里我使用的是yii框架。

1，phpthumb_ico 是生成ICO图标的类，源码如下

class phpthumb_ico {

    function phpthumb_ico() {
        return true;
    }


    function GD2ICOstring(&$gd_image_array) {
        foreach ($gd_image_array as $key => $gd_image) {

            $ImageWidths[$key]  = ImageSX($gd_image);
            $ImageHeights[$key] = ImageSY($gd_image);
            $bpp[$key]          = ImageIsTrueColor($gd_image) ? 32 : 24;
            $totalcolors[$key]  = ImageColorsTotal($gd_image);

            $icXOR[$key] = '';
            for ($y = $ImageHeights[$key] - 1; $y >= 0; $y--) {
                for ($x = 0; $x < $ImageWidths[$key]; $x++) {
                    $argb = $this->GetPixelColor($gd_image, $x, $y);
                    $a = round(255 * ((127 - $argb['alpha']) / 127));
                    $r = $argb['red'];
                    $g = $argb['green'];
                    $b = $argb['blue'];

                    if ($bpp[$key] == 32) {
                        $icXOR[$key] .= chr($b).chr($g).chr($r).chr($a);
                    } elseif ($bpp[$key] == 24) {
                        $icXOR[$key] .= chr($b).chr($g).chr($r);
                    }

                    if ($a < 128) {
                        @$icANDmask[$key][$y] .= '1';
                    } else {
                        @$icANDmask[$key][$y] .= '0';
                    }
                }
                // mask bits are 32-bit aligned per scanline
                while (strlen($icANDmask[$key][$y]) % 32) {
                    $icANDmask[$key][$y] .= '0';
                }
            }
            $icAND[$key] = '';
            foreach ($icANDmask[$key] as $y => $scanlinemaskbits) {
                for ($i = 0; $i < strlen($scanlinemaskbits); $i += 8) {
                    $icAND[$key] .= chr(bindec(str_pad(substr($scanlinemaskbits, $i, 8), 8, '0', STR_PAD_LEFT)));
                }
            }

        }

        foreach ($gd_image_array as $key => $gd_image) {
