32 bit png images on device with 16 bit display
===

Does anyone know how to convert 32 bit images to show on device with 16 bit display ?

I tried to create a 24 bit image with Qt QImage - [QImage QImage::convertToFormat ][1]


and save the result image, but the image I got was also 32 bit (I see the  this data in the properties of the output image - Bit Depth)
