/**
* \brief IconImageGenerator
* \details This filter will generate a valid Icon from the Pixel Data element (an
* instance of Pixmap).
* To generate a valid Icon, one is only allowed the following Photometric
* Interpretation:
* - MONOCHROME1
* - MONOCHROME2
* - PALETTE_COLOR
*
* The Pixel Bits Allocated is restricted to 8bits, therefore 16 bits image
* needs to be rescaled. By default the filter will use the full scalar range
* of 16bits image to rescale to unsigned 8bits.
* This may not be ideal for some situation, in which case the API
* SetPixelMinMax can be used to overwrite the default min,max interval used.
*
* \see ImageReader
