clearDeviceNImage
Free memory used by a DeviceN image.
clearDeviceNImage()
This function frees the memory used by the last call to
convertPageToDeviceNImage
.
Only one DeviceN rasterization (per PDF handle) is held in memory at a
time. If you call convertPageToDeviceNImage
again, the memory
used by the previous call to convertPageToDeviceNImage
will be
automatically freed.
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()
