cadnano.color module¶

This allows the model to have a Color object class without the need for PyQt5.QtGui.QColor

When running the Qt Application, QColor will be used, otherwise an API compatible class is used and exported as a Color object

Currently Color objects are unused in the model and colors are stored as QColor compatible hex string in format ‘#rrggbbaa’, and therefore is not exposed in the API documentation

class Color(*args)¶

Bases: object

Overloaded constructor using *args to be compatible with QColor

usage:

Color(r, g, b)

or:

Color('#rrggbb') for hex

hex() → str¶

The hex string name.

Returns:	`QColor` compatible hex string in format ‘#rrggbbaa’

name() → str¶

The hex string name. For QColor compatibility

Returns:	`QColor` compatible hex string in format ‘#rrggbbaa’

setAlpha(a: int)¶

Set the alpha 8 bit value

Parameters:	a (int) – 0 - 255

setRgb(r: int, g: int, b: int, a: int = 255)¶

Set the r, g, b and alpha 8 bit values

Parameters:	r – 0 - 255 g – 0 - 255 b – 0 - 255 a – 0 - 255

intToColorHex(color_number: int) → str¶

Convert an integer to a hexadecimal string compatible with QColor

Parameters:	color_number – integer value of a RGB color
Returns:	`QColor` compatible hex string in format ‘#rrggbb’
