This file format uses file extensions FTC and FTU. * FTC files are compressed textures (using standard texture compression). * FTU files are not compressed. Texture File Format The FTC and FTU texture files both use the same format. This has the following structure: {header} {format_directory} {data} Where: {header} = { u32:magic, u32:version, u32:width, u32:height, u32:mipmap_count, u32:format_count } * The "magic" number is "FTEX". * "width" and "height" are the dimensions of the texture. * "mipmap_count" is the number of mipmaps in the texture. * "format_count" is the number of texture formats (different versions of the same texture) in this file. {format_directory} = format_count * { u32:format, u32:where } The format value is 0 for DXT1 compressed textures and 1 for 24-bit RGB uncompressed textures. The texture data for a format starts at the position "where" in the file. Each set of texture data in the file has the following structure: {data} = format_count * { u32:mipmap_size, mipmap_size * { u8 } } * "mipmap_size" is the number of bytes in that mip level. For compressed textures this is the size of the texture data compressed with DXT1. For 24 bit uncompressed textures, this is 3 * width * height. Following this are the image bytes for that mipmap level. Note: All data is stored in little-Endian (Intel) byte order. � N)�BytesIO� )�Image� ImageFiles FTEXc @ s$ e Zd ZdZdZdd� Zdd� ZdS )� FtexImageFileZFTEXz Texture File Format (IW2:EOC)c C s t �d| j�d�� t �d| j�d�� t �d| j�d��| _t �d| j�d��\}}d| _|dksht�t �d| j�d��\}}| j�|� t �d| j�d��\}| j�|�}|tkr�d| _d d | j d dfg| _ n,|t kr�d d | j d d fg| _ n t d| ��| j� � t|�| _d S )Nz<I� z<iz<2i� �RGBr ZRGBAZbcn)r r r �raw)r r r z&Invalid texture compression format: %r)�structZunpack�fp�readZ_size�mode�AssertionError�seek� FORMAT_DXT1�sizeZtile�FORMAT_UNCOMPRESSED� ValueError�closer )�selfZ mipmap_countZ format_count�format�whereZ mipmap_size�data� r �5/usr/lib/python3/dist-packages/PIL/FtexImagePlugin.py�_openD s$ zFtexImageFile._openc C s d S )Nr )r �posr r r � load_seeka s zFtexImageFile.load_seekN)�__name__� __module__� __qualname__r Zformat_descriptionr r r r r r r @ s r c C s | d d� t kS )Nr )�MAGIC)�prefixr r r � _validatee s r$ z.ftcz.ftu)�__doc__r �ior � r r r" r r r r$ Z register_openr Zregister_extensionsr r r r �<module> s 5 %
