Property BitsPerPixel : Byte; (Read)
The number of bits per pixel. Most often this is 8
If the image is colour, then there is 3 * BitsPerPixel per pixel, for Red, Green, and Blue/ If the image is greyscale, there is only 1 * BitsPerPixel (note though, must greyscale source images will be converted to full colour when they are read.
Note that GDI+ 1.0 only supports up to 8 bits/plane. When dicom images with BitsPerPixel > 8 are converted to GDI+ images, the BitsPerPixel will effectively be reduced to 8
