loadbitmap

public java.awt.Image loadbitmap(java.lang.String sdir,
                                 java.lang.String sfile)

loadbitmap() method converted from Windows C code. Reads only uncompressed 24- and 8-bit images. Tested with images saved using Microsoft Paint in Windows 95. If the image is not a 24- or 8-bit image, the program refuses to even try. I guess one could include 4-bit images by masking the byte by first 1100 and then 0011. I am not really interested in such images. If a compressed image is attempted, the routine will probably fail by generating an IOException. Look for variable ncompression to be different from 0 to indicate compression is present. Arguments: sdir and sfile are the result of the FileDialog() getDirectory() and getFile() methods. Returns: Image Object, be sure to check for (Image)null !!!!
