[fitsbits] Image Showing..

[Alex]

First of all, I programmed the reader for FITS Files.

but, I can show the Image.. exactly, I can only show the image with
BITPIX = 8. yea.. Can't show the another BITPIX = 16, 32, -32,
-64.(probably, "BITPIX = 8" means 'unsigned char type'.. right?.. so,
can draw the image easily.. but, another can't.)

In detail, when I open the FITS file, some image's intensity value are
1826, 32456, etc. In my opinion, only 256 intensity image can show..
but, FITS some image's 1826, 32456, etc.. so, I want to know the way
FITS's data loading sequence. (ex. How did you normalized data for
0~255 level from -32xxx ~ 32xxx. if this way is right...)


please, Let me know the way!!
thank you.
