Specifies the number of bits per sample in a downsampled image. Allowed values are:

• The number of bits per sample: 1 , 2 , 4 , or 8

• When the value is greater than 1, monochrome images are converted to grayscale images.

• -1 , which forces the downsampled image to have the same number of bits per sample as the original image. (For monochrome images, this is the same as a value of 1.)

MonoImageDepth is not used unless DownsampleMonoImages and AntiAliasMonoImages are true.
