BGR Color to Java Color

[Andrew Arace]

Took me a while to come up with this (even though it looks simple) it
will convert a BGR color int (or long) like used in VB to a java Color
(java.awt.Color )

examples of this are:
colornum = 16777215; //pure white
colornum = 255; //pure red
colornum = 65280; //pure green
colornum = 16711680; //pure blue

public Color BGRColorToJavaC olor(int BGRColorNumber) {
//color codes as a ing in form "BGR"
return new Color((float)(B GRColorNumber & 0xFF),
(float)((BGRCol orNumber >> 8) & 0xFF),
(float)((BGRCol orNumber >> 16) & 0xFF));
}

Just putting this here to help people. my google groups search didn't
come up with anything like it, so i'm just trying to change that.

comments to my email please ;)

I don't understand the reason you convert to float.
You are doing bit operations that assume you have integers,
so why not use the "Color(int r, int g, int b)" constructor?

SORRY SORRY, messed that post up: turns out my 'tests' i did were on
black, and it worked fine...need to get rid of that (float) casting

public Color BGRColorToJavaC olor(int BGRColorNumber) {
//color codes as a int in form "BGR"
return new Color((BGRColor Number & 0xFF),
((BGRColorNumbe r >> 8) & 0xFF),
((BGRColorNumbe r >> 16) & 0xFF));
}

That's right now. Really sorry about that, I felt like an idiot after
i posted it, and 5 seconds later realized I had posted the wrong code.

Isn't there already a Color constructor that does this?
Color red = new Color(255); // looks red to me
Color blue = new Color(16711680) ; // looks blue too

hmm...i don't think so. i'll check out your examples there, but the
Color(int) constructor says "int rgb" where the color i am passing in,
the way VB represents it, its BGR (reversed endian)
....i hope i didn't spend that time for nothing.

You're right. I wrote a test program and looked at it, but
forgot which part I'd made red and blue. The good news is
that your time wasn't wasted.
