Only TIFF and DICOM file formats are capable of saving bitmaps that have been window-leveled. Bitmaps can be window-leveled by calling the LBitmap::WindowLevel function or by loading a bitmap from a file format that supports window-leveling. If a window-leveled bitmap is saved as any other file format, the bitmap data will be converted before being saved. The conversion is done as follows:
the data is converted to the full bit range
(LowBit = 0, HighBit = BitsPerPixel – 1)
the LUT is converted so first entry = 0 (BLACK)
and last entry = 255 (WHITE).
When the bitmaps are saved as DICOM or TIFF, no conversion is made.
