Description
In the current specification:
<xsd:documentation>A color used render this channel - encoded as RGBA The default value "-2147483648" is #FFFFFFFF so solid white (it is a signed 32 bit value)</xsd:documentation>
Two problems with this:
1) "-2147483648" is #FFFFFFFF
This is from what I can tell, false. 0xFFFFFFFF is -1 and 0x80000000 is -2147483648.
2) For the default, -2147483648 would be 0x80000000 i.e. mid intensity transparent red, i.e. completely invisible. 0xFFFFFFFF would be opaque white, i.e. completely invisible.
(The above assumes A=0 is transparent, A=255 is opaque; is this the interpretation used in our spec?)
Regards,
Roger
