resetDeviceNChannelMask

Reset the DeviceN channel mask to all-on.
resetDeviceNChannelMask()
This function sets the DeviceN channel mask so that all channels are "on".

The getDeviceNToRGBPicture uses a mask that controls which color channels are included in the conversion. Channels that are "on" are included; channels that are "off" do not contribute to the output pixels. The channels are the same as reported by getDeviceNChannelName. The mask only affects the output of getDeviceNToRGBPicture.

The DeviceN channel mask is automatically reset (all channels "on") on each call to convertPageToDeviceNImage, convertPageToDeviceNImageWithAlpha, convertRegionToDeviceNImage, or convertRegionToDeviceNImageWithAlpha.

VB:
rast.convertPageToDeviceNImage(page, dpi) rast.resetDeviceNChannelMask() nChannels = rast.getNumDeviceNChannels() For i = 0 To nChannels-1 channelName = rast.getDeviceNChannelName(i) If .... Then rast.setDeviceNChannelMask(i, true) Else rast.setDeviceNChannelMask(i, false) End If Next i pic = rast.getDeviceNToRGBPicture() ... rast.clearDeviceNImage()
