Luis Bernardo resolved BATIK-1077.
----------------------------------

    Resolution: Duplicate

I think this must the the same as BATIK-963, which has been fixed on trunk.

> 28 00 00 00 = header size (40 bytes)
> c0 00 00 00 = width of image (192)
> 2f 00 00 00 = height of image (47)
> 01 00 = number of planes (1)
> 08 00 = bits per pixel (8)
> 00 00 00 00

> 00 00 00 00
> 00 00 00 00
> 00 00 00 00 = number of used colours (0, meaning "use all of them")
> 00 00 00 00 <- end of header (40th byte)
> 192 (width) x 47 (height) x 1 (bytes per pixel) x 1 (planes) = 9024
> Header = 40 bytes
> Palette = 256 bytes (2^8 because it's 8 bits per pixel)
> Size of image = 9024 bytes (from calculation above)
> Total size = 9320 > 9068 bytes available data
> Despite these calculations seeming to show that the image is invalid, it does open in OpenOffice perfectly fine, leading me to wonder how they are doing that...
