Re: [Openexr-devel] How about an RGBAInputFile::setLayer() function?

[Florian Kainz]

I've added a setLayerName() function to class RgbaInputFile and
class TiledRgbaInputFile.  The change has been checked into CVS.
There's one caveat: after calling setLayerName(), you must call
setFrameBuffer() before reading any more pixels; setLayerName()
invalidates the previous frame buffer settings.

Affected files:

    IlmImf/ImfRgbaFile.h
    IlmImf/ImfRgbaFile.cpp
    IlmImf/ImfTiledRgbaFile.h
    IlmImf/ImfTiledRgbaFile.cpp
    IlmImfTest/testRgba.cpp
    IlmImfTest/testTiledRgba.cpp
