Colors class¶
This page explains the Colors class.
What class is this?¶
The Colors class has Color constants, such as the BLACK_000000, GRAY_999999, WHITE_FFFFFF, and RED_FF0000.
Each suffix is a hexadecimal color code of its color.
Basic usage¶
These class constants behave the same as a Color value.
import apysc as ap
stage: ap.Stage = ap.Stage(
stage_width=150,
stage_height=150,
background_color=ap.Colors.GRAY_333333,
stage_elem_id="stage",
)
rectangle: ap.Rectangle = ap.Rectangle(
x=50,
y=50,
width=50,
height=50,
fill_color=ap.Colors.CYAN_00FFFF,
line_color=ap.Colors.WHITE_FFFFFF,
line_thickness=3,
)
