[SDL] Converting a surface to another color

[Viktor Dick]

Thanks. If I understand rightly, the gradient function would put the
lines with lineColor or something like that. Is there someone that could
give me some code how to apply an alpa mask? I'm not familiar with
transparency under SDL and I did not found any tutorial explaining this
well enough.
Thanks.
