php - Compress image in codeigniter 4 removes transparency

Question

I am using compress image from codeigniter 4 library with below code :

ConfigServices::image()->withFile($this->request->getFile('storeimage'))->reorient()->save('images/store/test.png', 70)

But it removes transparency png image. Can i compress png image without losses the transparency in ci 4?

I put below code in GDHanlder.php (save function) but it makes compress image not working, image size result still same and not compressed

imageAlphaBlending($this->resource, true);
imageSaveAlpha($this->resource, true);

Into this :

case IMAGETYPE_PNG:
    imageAlphaBlending($this->resource, true);
    imageSaveAlpha($this->resource, true);

    if (! function_exists('imagepng'))
    {
        throw ImageException::forInvalidImageCreate(lang('images.pngNotSupported'));
    }

    if (! @imagepng($this->resource, $target))
    {
        throw ImageException::forSaveFailed();
    }
    break;
