---------------------------------------
Hi Charles,
I checked all my IO objects. The byte[] from Sanselan is 1666 in length.
ByteArrayOutputStream.toByteArray().length also returns 1666. That output
stream is used to initialize a ByteArrayInputStream that is sent to Sanselan. I
cannot find a case where the data is being truncated.
That being said, your reasoning is probably correct, I just can't think of
where the data is not being fully read. I found out through further testing,
that this process also fails for TIFFs when the image is large, as the
following error shows. So I think you are correct. But I also checked the array
lengths for my IO objects involved with the TIFF, and they are all the same
size as the byte[] from Sanselan...
java.io.IOException: Bad Code: -1 codes: 258 code_size: 9, table: 4096

This is how I use Sanselan's function that takes the correctly created
ByteArrayInputStream:
final BufferedImage image = Sanselan.getBufferedImage((InputStream)
contents.getTransferData(dataFlavor));
Is it possible that this could be an issue with Sanselan?

> Two issues with BMPs.

> Key: SANSELAN-14
> URL: https://issues.apache.org/jira/browse/SANSELAN-14
> Project: Sanselan
> Issue Type: Bug

> Environment: Windows, Mac, Linux, Sanselan 0.94
> Reporter: Kevin Theisen
> Priority: Minor
> Attachments: SanselanTest.bmp

> 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:
> org.apache.sanselan.ImageReadException: BMP: Strange BitmapDataOffset: 266
> (expected: 1078, PaletteLength: 1024, header_size: 54)
