There seems to be a slight problem with setting image or channel depth. Using Q16, setting the depth to 8 bit, you will have a 16 bit file.
Doesn't matter with better previews / image processing programs. With Win systems the display for TIFF files is a kind of psychedelic art.
This took me hours until I did check with PhotoShop. Besides: even if it works with RGB and PNG files, this consumes resources. Have a look on file size.
Only way out: change to Q8.
IMHO there is no way to run Q8 and Q16 simultaneously.
The above said concerns also setImageDepth.
(PECL imagick 2.0.0)
Imagick::setImageDepth — Sets the image depth
bool Imagick::setImageDepth ( int
Sets the image depth.
TRUE on success.
Throws ImagickException on error.
