[Sdldoc-devel] Call for clarification of the terms used

[Maxim S. <So...@Fr...>]

Hi,

I'm currently working on Russian translation of documentation, but stuck in
inability to adequately translate some terms used there. Does anyone could
explain me precise meaning of some terms? For example:

Blit - ? As far as I understand it is a "copy operation from one surface to
another", but there could be other meanings of that.
Colorkey Blit -?
Alpha Blit -?

Please let me know if someone willing to explain these and possibly others
terms.

-Maxim

Blit generally means to copy a large amount of information from one area
of computer memory to another. These days, however, blit generally refers
to copying graphical information.

A "colorkey blit" isn't (as far as I know) in general use. Its the same as
a graphical blit accept one color isn't copied.

Am...not too sure how to explain alpha.:)

Thought you were looking for some advanced explanation of alpha.:) Oh

How are things going?
