No.
You can only request a similar pen to a RGB color:

REQUEST ("PEN_OF_RGB", colorInRGB, pen)

Do you have any example script of this? Thanks

[runxel]

rr = REQUEST("PEN_OF_RGB", "0 1 0.2", _greenishpen)
!!! color range 0 to 1  //  ＷＴＦ ＧＳ?

pen _greenishpen

set line_type   1
line2           0,0,5,0

Whoever did the 0 to 1 thing was clearly effing around.

It is 0-1 in all MacOS at least in early versions 😉
anyway it is more accurate BTW: 256 points vs _the_accuracy_You_need 😉
Not that I like it...and in any script I use X/255 to get the GDL needed value while any soft would rather give 0..255.

Best Regards,
Piotr

I know Piotr, but the accuracy is not the point.
It is about consistence and usability.
The implemented way is just total madness! 😉 It's like cooking by receipt with imperial units but living in Europe.

Hello,

Just to revisit this, how can I convert an RGB value into Graphisoft's 0-1 system?

Thanks

0 * 255 = 0 (black)
1 * 255 = 255 (white)
<< -- >>
0 / 255 = 0
255/255 = 1
