Do you think the file is meant to be completely transparent? (It is imo likely that it actually should not be transparent at all.)
Could you try to encode an image that is part transparent, part opaque?

Sorry, I don't know how to create transparent sun raster (if it's possible), so I suggest supporting it without it.

Mostly fixed, remaining issues depend on ticket #869.

IMHO blocking this bug by another, unrelated bug is pointless. This bug should and can be fixed without waiting for #869 to be fixed.

ImageMagick displays wrong colors for this sample, what application created this file?

Our decoder incorrectly decodes 32bit ras created with ImageMagick.

Need more info about generated sample.

Attached sample decodes visually incorrect now, but decoder matches what Gimp, ImageMagick and xview do and what the terse specification indicates.
