removeDeviceNChannel
Remove a DeviceN color channel.
removeDeviceNChannel([in] int channelIdx)
This function removes (sets to zero) one color channel of the DeviceN
image generated by the last call to
convertPageToDeviceNImage.
This is useful to remove one or more channels before calling
getDeviceNToRGBPicture.
The channel mask functions, resetDeviceNChannelMask and
setDeviceNChannelMask, provide equivalent functionality and are
more efficient.
VB:
rast.convertPageToDeviceNImage(page, dpi)
nChannels = rast.getNumDeviceNChannels()
For i = 0 To nChannels-1
channelName = rast.getDeviceNChannelName(i)
If .... Then
rast.removeDeviceNChannel(i)
End If
Next i
pic = rast.getDeviceNToRGBPicture()
...
rast.clearDeviceNImage()
