See: :ref:`concept-modes`. Defaults to "RGB" :param palette: An optional palette. If given, it must be a bytearray, an array or a list of ints between 0-255 and of length ``size`` times the number of colors in ``mode``. The list must be aligned by channel (All R values must be contiguous in the list before G and B values.) Defaults to 0 through 255 per channel. :param size: An optional palette size. If given, it cannot be equal to or greater than 256. Defaults to 0. �RGBNr c C sv || _ d | _|p$ttd��t| j � | _i | _d | _|dkrTt| j �d t| j�ksj|dkrr|t| j�krrtd��d S )N� r zwrong palette size) �mode�rawmode� bytearray�range�len�palette�colors�dirty� ValueError)�selfr r �size� r �2/usr/lib/python3/dist-packages/PIL/ImagePalette.py�__init__' s � �zImagePalette.__init__c C sH t � }| j|_| j|_| jd k r0| jd d � |_| j�� |_| j|_|S )N)r r r r r �copyr )r �newr r r r 2 s zImagePalette.copyc C s$ | j r| j | jfS | jd | �� fS )z� Get palette contents in format suitable for the low-level ``im.putpalette`` primitive. .. warning:: This method is experimental. z;L)r r r �tobytes)r r r r �getdata> s zImagePalette.getdatac C sH | j rtd��t| jt�r | jS t�d| j�}t|d�r@|�� S |�� S )zUConvert palette to bytes. .. warning:: This method is experimental. �!palette contains raw palette data�Br ) r r � isinstancer �bytes�array�hasattrr �tostring)r Zarrr r r r I s zImagePalette.tobytesc C s� | j rtd��t|t�r�z | j| W S tk r� t| jt�rLt| j�| _t | j�}|dkrftd��|| j|< |d | j|< |d | j|d < |d | j|d < d| _ | Y S X n td| ��d S ) zgGiven an rgb tuple, allocate palette entry. .. warning:: This method is experimental. r r z$cannot allocate more than 256 colorsr r � i zunknown color specifier: %rN) r r r �tupler �KeyErrorr r r r r )r Zcolor�indexr r r �getcolorZ s$ zImagePalette.getcolorc C s� | j rtd��t|t�r"t|d�}|�d� |�d| j � td�D ]|}|�d| � t|t| j� |d t| j� �D ]<}z|�d| j | � W qx t k r� |�d � Y qxX qx|�d � qD|� � d S ) zVSave palette to text file. .. warning:: This method is experimental. r �wz # Palette z # Mode: %s r z%dr z %dz 0� N) r r r �str�open�writer r r r � IndexError�close)r �fp�i�jr r r �savet s & zImagePalette.save)r Nr ) �__name__� __module__� __qualname__�__doc__r r r r r" r' r2 r r r r r s r c C s t � }| |_||_d|_|S )Nr )r r r r )r �datar r r r �raw� s r8 c C s6 g }| dkr.t d�D ]}|�|| d � qnt�|S )Nr r � )r �append�NotImplementedError)Zblack�white�lutr0 r r r �make_linear_lut� s r> c C s4 g }t d�D ]"}|�t|d | d d �� q |S )Nr g �o@g �?)r r: �int)Zexpr= r0 r r r �make_gamma_lut� s r@ r c C s& t td��}|�� t| |t| � �S �Nr )�listr �reverser r )r r r r r �negative� s rD c C s@ ddl m} g }tdt| � �D ]}|�|dd�� q t| |�S )Nr )�randintr r9 )�randomrE r r r: r )r rE r r0 r r r rF � s rF �#fff0c0c C s@ t �| �\}}}td|�}td|�}td|�}td|| | �S )Nr r )r Zgetrgbr> r )r< �r�g�br r r �sepia� s rK c C s t | ttd��t| � �S rA )r rB r r )r r r r �wedge� s rL c C sv t | d��b}tjtjtjfD ]B}z$|�d� ||��� }|rBW qhW q ttfk r\ Y q X q td��W 5 Q R X |S )N�rbr zcannot load palette) r+ r r r �seekZ getpalette� SyntaxErrorr �OSError)�filenamer/ ZpaletteHandlerr= r r r �load� s � rR )r )r )rG )r )r � r r r r r r8 r> r@ rD rF rK rL rR r r r r �<module> s v
