Imagick::setImageDepth — Sets the image depth
Diese Funktion ist bis jetzt nicht dokumentiert. Es steht nur die Liste der Argumente zur Verfügung.
Sets the image depth.
Liefert TRUE bei Erfolg.
Wirft ImagickException bei Fehlern.
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.
