Decimal to Hex text string ?

[Werty]

How do I convert a variable, that has a Decimal value between 0 and 65535 into a text string that looks like this...

If Decimal = 0

Hex should be = #000000000000

If Decimal is = 1

Hex should be = #000100010001

If Decimal is = 65535

Hex should be = #FFFFFFFFFFFF

As you see, the string should contain the Decimal 3 times in a row, with the hash sign infront.

I need it to feed an Imagemagick command that looks like this..

$compare = $img.Compare("bitmap1.bmp", _
                "bitmap2.bmp", _
                "-depth", "16", _
                "-highlight-color", "#123412341234", _
        "bitmapresult.pgm" )

I wanna feed the "#123412341234" part with a variable, but dunno how to convert the decimal variable into such a text string.

Anyone ?

Its for Imagemagick? Would be interesting to see this ...

$dec = 65535

$compare = $img.Compare("bitmap1.bmp", _
        "bitmap2.bmp", _
        "-depth", "16", _
        "-highlight-color", _ColorDecToHex4($dec),
_ "bitmapresult.pgm")

Func _ColorDecToHex4($dec)
    $Hex = hex($dec,4)
    Return "#" & $Hex & $Hex & $Hex
EndFunc

lol, was it that simple, guess I should have read up on Hex() before asking, only remember it from my old ZX Basic days, where there was no option for defining how many chars.

I'm making height maps and was limited to 8bit 256 grays...

But now I got 65536 grays to work with.

Thanks for your help.
