Editing RGBA color model (section)

=== RGBA32 ===

{{Disputed section|date=December 2015}}

In some software originating on big-endian machines such as [[Silicon Graphics]], colors were stored in 32 bits similar to ARGB32, but with the alpha in the ''bottom'' 8 bits rather than the top. For example, <code>808000FF</code> would be Red and Green:50.2%, Blue:0% and Alpha:100%, a brown. This is what you would get if RGBA8888 data was read as words on these machines. It is used in [[Netpbm#Transparency|Portable Arbitrary Map]] and in [[FLTK]], but in general it is rare.

The bytes are stored in memory on a little-endian machine in the order ABGR.
