[gl4java-usergroup] Concerns about unsigned glColor* methods

[Pontus L. <po...@ly...>]

Hello,

I have a question about the glColor3{ub,us,ui} methods in GL4Java:

The arguments to these methods are still signed quantites. The methods
seem to rely on the Java compiler representing the typecast (byte)255
value with the unsigned byte value 255. Does the language specification
guarantee this?

In particular, it seems impossible to get glColor3ui method to produce the
same result as glColor3f(1.0,0.0,0.0). Maybe this should be considered a
bug?

Regards,

Pontus
