I am setting the TopDown property to true in BMPWriteParam by calling setTopDown(true). I am getting all the supported compression types and looping through them one by one and setting it to the write param. I am writing the image using each of these compression types, with topdown true using BMPImageWriter.

I noticed that the image is actually inverted for some of the compression types such BI_RGB and BI_BITFIELDS whereas it is normal for other compression types such as BI_JPG and BI_PNG. The spec does not say anything about the dependency of TopDown on compression. I feel the behavior of TopDown must be same regardless of what compression types are used.

This is reproducible on all platforms right from Tiger-FCS.

I have attached a sample test that would demonstrate this bug.
