PHP基于yii框架实现生成ICO图标

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) {

 $icXOR[$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) {

 }
 
 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) {

 }
 }

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

 }
 
 function GetPixelColor(&$img, $x, $y) {
 if (!is_resource($img)) {
 return false;
 }
 return @ImageColorsForIndex($img, @ImageColorAt($img, $x, $y));
 }
 
}

2，后台

引入类：

Yii::$enableIncludePath = false;
Yii::import ( 'application.extensions.ico.phpthumb_ico', 1 );

解决生成黑色背景的问题

imagealphablending($resize_im, false);//不合并颜色,直接用$im图像颜色替换,包括透明色 imagesavealpha($resize_im, true);//不要丢了$resize_im图像的透明色 完整方法：
