消息：imagecreatefrompng（）：SSL操作失败，代码为1

I am getting the errors below:

Message: imagecreatefrompng(): SSL operation failed with code 1

Message: imagecreatefrompng(): Failed to enable crypto

when I run this code using PHP GD.

function image_test() {
    $im = imagecreatefrompng(base_url()."assets/developed/images/center-poster-bg-transparent.png");
    imagepng($im, APPPATH."../TESTIMAGE.png");
}

Can anybody help me out with why this is happening?

I guess you using codeigniter framework. I have the same problem earlier. And my solution is using the codeigniter parameter FCPATH.

Your code:

function image_test() {
    $im = imagecreatefrompng(base_url()."assets/developed/images/center-poster-bg-transparent.png");
    imagepng($im, APPPATH."../TESTIMAGE.png");
}

have to modify to

function image_test() {
    $im = imagecreatefrompng( FCPATH."assets/developed/images/center-poster-bg-transparent.png" );
    imagepng($im, APPPATH."../TESTIMAGE.png");
}

Hope it can help you.
