---------------------------------------
Hi Charles,
Sanselan can write the BMP to a file and then read it back in without error.
The problem occurs when I take the byte[] generated by Sanselan, turn it into a
stream, and then read it back into Sanselan. There never really is a physical
file. The BufferedImage that I use is generated in real time from some drawing
on a JPanel.
To save the file, I intercepted the InputStream and wrote it to a file
(SanselanTest.bmp). And yes, when reading the file with Sanselan, the error
occurs. Sorry I didn't think about doing this in my first post. The error when
reading is as follows:
org.apache.sanselan.ImageReadException: BMP: Strange BitmapDataOffset: 266
(expected: 1078, PaletteLength: 1024, header_size: 54)

> Hi all,
> Two things. The first is minor. There is a System.out.println() that should
> be commented out in the BMP code. I see a lot of lines like this:
> "bits_per_sample: 8"
> The second is an error. When I create a BMP with Sanselan, everything works,
> and I can load the output into OpenOffice without problem from the System
> Clipboard. However, when trying to recreate the BufferedImage with Sanselan
> from the same exact output Sanselan created, I get the following error:
