[bug-solved] Colours element byte order on Mac

[wally]

I've got custom looknfeel buttons which are intended to appear darker in the "off" state via this Colours element:

Code: Select all

        <StateImagery name="Normal">
            <Layer>
                <Section section="OffNoHover" />
                <Section section="icon" >
                  <Colours
                    topLeft="ffb0b0b0"
                    topRight="ffb0b0b0"
                    bottomLeft="ffb0b0b0"
                    bottomRight="ffb0b0b0" />
                </Section>
            </Layer>
        </StateImagery>



(darkening of RGB components, with full opacity)

But on a Mac rendering with OpenGL, instead I see buttons in this state rendering partially transparent. And changing the colours above
from ffb0b0b0 to b0b0b0ff produces full opacity

So it seems like the colour bytes are applied in the reverse order on the mac? (Pixel format or endianness issue?)

I believe the expected colour format is AARRGGBB from the falagard docs, regardless of platform.

Specs:
PowerPC mac, OSX 10.5.4.
CEGUI 0.6.1 precompiled packages

On Windows platform, rendering with DirectX or OpenGL produces the correct results (full opacity).

Thanks

Hi,

You're pretty much correct about the endianness - this is a bug!

I'll try and get it fixed ASAP. My Mac is an Intel variety BTW, so sometimes these things are gonna slip through

Not a critical issue for me - I can probably work around it if I have to and I guess it won't be a problem on intel macs.
Apart from that (and the framework issue I reported elsewhere) it was pretty smooth getting the GUI running on the mac. So good job on that

[CrazyEddie]

It's good to hear that aside from a couple of glitches, the prebuilt framework functions as expected.

The decision to keep the framework location in the 'wrong' location for the 0.6.x releases was one of those where I felt between a rock and a hard place - I have no idea why it was originally set up that way.

Once I get some time for CEGUI related work, one of the first jobs will be to get the new XCode project for the 0.7 (currently svn trunk) up and running - especially as I find myself spending more and more time on the Mac, it's actually quite addictive

Just an update that CEGUI version 0.6.2 solves this issue for me. Colour multipliers, background colours etc all work correctly for me now on PPC macs.
Thanks!

Thanks for confirming that our fix has indeed worked. While I believed that I had got it right, I was unable to test it for sure.
