Java代码
- /**
- 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 !!!!
