Description:
------------
Image_Transform 0.2 beta

in driver GD.php line 332.

Don´t Create a new true color image, because It can´t detect if the function "ImageCreateTrueColor" exists.

//if(@ImageCreateTrueColor()){

I suggest replace it with this line:

if(function_exists('ImageCreateTrueColor')){

hello again and sorry for my bad english. The bug exactly is in the "if" conditions that fails in PHP5 (bad counted parameters), not exactly in the "ImageCreateTrueColor()" function, because "if" statement doesn´t return TRUE as it should do because PHP5 comes with gd2 support.

I have solved it with the "function_exists()".

best regards
Ricardo.

My code suggested:

if(function_exists('ImageCreateTrueColor')){
$new_img =ImageCreateTrueColor($new_x,$new_y);
} else {
$new_img =ImageCreate($new_x,$new_y);
}

if(function_exists('ImageCopyResampled')){
ImageCopyResampled($new_img, $this->imageHandle, 0, 0, 0, 0, $new_x, $new_y, $this->img_x, $this->img_y);
} else {
ImageCopyResized($new_img, $this->imageHandle, 0, 0, 0, 0, $new_x, $new_y, $this->img_x, $this->img_y);
}
