VB6:
rast.convertPageToDeviceNImage page, dpi nChannels = rast.getNumDeviceNChannels For i = 0 To nChannels-1 channelName = rast.getDeviceNChannelName(i) channelCMYK = rast.getDeviceNChannelCMYK(i) pic = rast.getDeviceNPicture(i) ' each channel has an 8-bit grayscale bitmap, similar to what ' is returned by convertPageToPicture in imageGray mode ... Next i rast.clearDeviceNImage
