Haw many channels does a QPixmap have?

[ricardo]

Hi friends!

Is it possoble to know how many channels a qpixmap have?
I see a hasAlphaChannel() method, but no more.
I would like to avoid black and white images (1 channel)

Any suggestion?

Thanks in advance.

See QPixmap::depth()

Returns the depth of the pixmap.

The pixmap depth is also called bits per pixel (bpp) or bit planes of a pixmap. A null pixmap has depth 0.
