PHP generates ICO icon _php instance based on Yii framework

1,phpthumb_ico is the class that generates the ICO icon, the source code is as follows

Introduction class:

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

Solve the problem of generating a black background

Imagealphablending ($resize _im, false);//Do not merge colors, directly replace with $im image color, including transparent color
Imagesavealpha ($resize _im, true);//Do not lose the transparent color of the $resize_im image
