Configuration options for Thumb Nail PlugIn

RBNB Server Address | The server to which the PlugIn connects.
PlugIn Name | The registered name of this instance of ThumbNail PlugIn
JPEG Source/Channel | An optional argument which specifies the Source/Channel of the JPEG images. If specified, only requests for scaled images from this Source/Channel will be served; the RBNB Server will not forward any other requests to the PlugIn.
Image Scale Factor | A value from 0 - 4 which specifies the amount of scaling. Values from 0 - 1 will produce an output image smaller than the input image; values from 1 - 4 will produce an output image larger than the input image. A scale factor of 1.0 will keep the same image size.
Image Quality | A value from 0 - 1 which specifies the quality of the output image. A value of 0.0 corresponds to very high compression, very low quality. A value of 1.0 corresponds to low compression, very high quality.
Maximum Number of Images | For a multi-image request (that is, a PlugIn request with a non-zero duration) this parameter specifies the number of output images. The timestamp of the images will be evenly spread over the duration.
