RGB Problem

[<David.C#S4701L>]

According to my friend (and http://www.javascripter.net/faq/hextorgb.htm )

Code: Select all

R = Red($413eba)
G = Green($413eba)
B = Blue($413eba)

MessageRequester("", Str(R)+" "+Str(G)+" "+Str(B))

and

Code: Select all

R = 10
G = 20
B = 30

MessageRequester("", Hex(RGB(R,G,B)))

Is actually returning the combination BGR (Blue, green, red) instead of RGB. (red green blue)

What is the problem here? Come on ! all is correct.
No bug. Don't scare to people :roll:

[..::Origin::..]

Code: Select all

R = Red($413eba)
G = Green($413eba)
B = Blue($413eba)

MessageRequester("", Str(R)+" "+Str(G)+" "+Str(B))

It Is done as BBGGRR, I do not think the functions, Red() : Blue() : Green; were supposed to be used with this.

A quick modification would be to just do:

Code: Select all

R = Blue($413eba)
G = Green($413eba)
B = Red($413eba)

MessageRequester("", Str(R)+" "+Str(G)+" "+Str(B))

As much as It doesn't look right, It works fine.

specifying a color numerically is always done with Red as the lower digit.

$FF is full red, right ?

So $0000FF is still full red... And you got the point.

[PB]

People tend to look at $0000FF like this:

Code: Select all

$0000FF
 RRGGBB

And they think FF relates to BB, which is wrong (as Fred pointed out).

Blame intel for this behaviour. All x86 based CPU's store 16bit and 24bit and 64bit values etc. "in reverse".

Search around this forum though, both I and others have done a few small snippets of code and examples on how to invert/flip the RGB numbers.

@Fred, maybe a flip value command could be added to a future PB? In ASM it's like a single operator at least for 32bit values.
