getDeviceNChannelName
Get the name of a DeviceN color channel.
getDeviceNChannelName([in] int channelIdx, [out, retval] BSTR *name)
This function returns the name of the specified channel generated by
the last call to
convertPageToDeviceNImage.
The first four channel names will always
be "Cyan", "Magenta", "Yellow",
and "Black". Additional channels will be custom (spot)
colors used on the page.
VB:
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()
