促銷圖像

這個項目旨在開發Python PYPI軟件包，不僅可以處理顏色文本輸出，還可以在文本中應用顏色效果，例如漸變。

介紹

該軟件包使用ANSI Escape序列選擇圖形演奏，以便將顏色和样式應用於文本和背景。這個軟件包與其他軟件包有何不同？

8位代碼以及4個位代碼
有一個不斷擴展的效果庫，可以應用於較大的文本塊。
超級光滑且簡單的界面

NB

不同的終端呈現不同的顏色，有些終端甚至根本沒有渲染ANSI逃脫序列，從而導致了大量的文本。使用ANSI逃生代碼播放，它正在播放。

一些基本的顏色很少用來突出不同的記錄水平，但是您無法在嚴肅的項目中帶走顏色。

入門

首先，有4個位和8個位代碼可用，分別從colour_fx.four_bit和colour_fx.eight_bit導入。但是，可以一起使用8位和4個位代碼。

NB

這些模塊中的對象僅提供在ANSI逃生序列中要使用的值。他們將需要使用compile_ansi_code將它們編譯為ANSI逃生序列，該compile_ansi_code可以from colour_fx import compile_ansi_code 。

4位示例

 from colour_fx import compile_ansi_code
from colour_fx . four_bit import Colour , Style

blinking_red_on_yellow = compile_ansi_code (
    # add as many ANSI values as you like and receive a single ANSI
    # escape sequence to handle all effects
    Colour . RED ,
    Colour . YELLOW . bright_background ,
    Style . BLINK
)

# an empty call to compile_ansi_code() gives the reset ANSI escape
# sequence which resets the way text is rendered
RESET = compile_ansi_code ()

print ( F"HELLO, { blinking_red_on_yellow } WORLD { RESET } !" )

8位示例

NB

與4位顏色相比，不同終端之間的8位顏色在外觀上更加不可預測。

`SimpleColour`

 from colour_fx import compile_ansi_code
from colour_fx . eight_bit import SimpleColour

red_on_yellow = compile_ansi_code (
    # add as many ANSI values as you like and receive a single ANSI
    # escape sequence to handle all effects
    SimpleColour . RED ,
    SimpleColour . YELLOW . bright_background ,
)

# an empty call to compile_ansi_code() gives the reset ANSI escape
# sequence which resets the way text is rendered
RESET = compile_ansi_code ()

print ( F"HELLO, { red_on_yellow } WORLD { RESET } !" )

        grey_array [ idx ],
        grey_back [ idx ],

# an empty call to compile_ansi_code() gives the reset ANSI escape
# sequence which resets the way text is rendered
RESET = compile_ansi_code ()

# Accessing the individual ANSI escape codes in the list of codes to
# create a gradient

`RGB`

 from colour_fx import compile_ansi_code
from colour_fx . eight_bit import RGB


# RGB is different to the rest in that you need to pass values in and
# initialise the object rather than treating as an Enum
# RGB values should be an integer between 0 and 5 inclusive
spectrum = [
    RGB ( 5 , 0 , 0 ). foreground ,
    RGB ( 3 , 2 , 0 ). foreground ,
    RGB ( 1 , 4 , 0 ). foreground ,
    RGB ( 0 , 4 , 1 ). foreground ,
    RGB ( 0 , 2 , 3 ). foreground ,
    RGB ( 0 , 0 , 5 ). foreground ,

# compiling spectrum into ANSI escape sequences while adding a
# white background
s = [
    compile_ansi_code ( spec , RGB ( 5 , 5 , 5 ). background )
    for spec in spectrum

# an empty call to compile_ansi_code() gives the reset ANSI escape
# sequence which resets the way text is rendered
RESET = compile_ansi_code ()

# Accessing individual elements of s allows a gradient

現在，這是激發此軟件包的創建，能夠將梯度應用於大型文本的原因。
