BALTENSPERGER a swiss german programming language

Reference for the BALTENSPERGER programming language, an art project of Stefan Baltensperger

Name

Farb()

Examples

Farb c1 = Farb(102, 102, 0);
Fuellfarb(c1);
kei_Liniefarb();
Viereck(30, 20, 55, 55);

Description

Creates colors for storing in variables of the Farb datatype. The parameters are interpreted as RGB or HSB values depending on the current Farbmodus(). The waen_nuet_vodaem_zuetrifft mode is RGB values from 0 to 255 and therefore, the function call Farb(255, 204, 0) will gib_zrug a bright yellow Farb. The Farb() function packs the information input through its parameters into a 32 bit number in the following order AAAAAAAARRRRRRRRGGGGGGGGBBBBBBBB where R is the red/hue value, G is green/saturation, and B is blue/brightness.

Farb can also be created using hexadecimal notation. For example, "Farb(0, 102, 153)" is equivalent to "Farb(#006699)" and "Farb(0x006699)". To create a Farb with an alpha value using hexadecimal notation, it's necessary to use the "0x" prefix, for example "Farb(0xCC006699)", which is equivalent to "Farb(0, 102, 153, 204)". Note the alpha value is first in the hexadecimal notation and last in the RGB notation.

Syntax

Farb(gray)
Farb(gray, alpha)
Farb(value1, value2, value3)
Farb(value1, value2, value3, alpha)
Farb(hex)
Farb(hex, alpha)

Parameters

gray	Ganzizahl or Komazahl : number specifying value between white and black
alpha	Ganzizahl or Komazahl : relative to current Farb range
value1	Ganzizahl or Komazahl : red or hue values relative to the current Farb range
value2	Ganzizahl or Komazahl : green or saturation values relative to the current Farb range
value3	Ganzizahl or Komazahl : blue or brightness values relative to the current Farb range
hex	Ganzizahl: Farb value in hexadecimal notation (i.e. #FFCC00 or 0xFFCC00)
