Compatible issues with Imagick Transparent?

I have my local with version ImageMagick 6.7.3-10 (PHP 5.2.10) and server side with ImageMagick 6.5.4-7 (PHP 5.3.9). It happened that server side doesn't generate transparent background but other colours still working. However local are just good with transparent background. Anyway I can solve in order to use transparent background on server side?

$canvas  = new Imagick();
$canvas->newImage( $size, $size, new ImagickPixel( 'transparent' ) );

I had the same issue with code developed locally not working in production for transparent pixels. I tried all the solutions above and transparency simply wasn't working. In the end I changed $im->setImageFormat( 'png24' ); to $im->setImageFormat( 'png' ); and it all started working again. "png24" format must have been added later.

make sure that you save the result in a format that actually supports transparancy... thus NOT JPG, but GIF or PNG.... It sounds simple, but too often this is forgotten (especially when not explicitly defined)

Well for me didn't work 'none' nor 'transparent' but 'rgba(250,15,150,0)' had ended my long agony with Imagick trully sparse documentation.

Have you tried none rather than transparent?
