描述

Required skills: Python, Cython

Difficulty: Medium

DDS files are used to store terrain textures in the Definitive Editions of AoE1 and AoE2. We will need to convert them to PNG so that they can be used by openage. pillow supports DDS, but their parser is written in Python. For maximum speedup, we should implement A parser written in Cython with Python glue code to attach it to the converter.

Renderdoc has a C++ implementation of a DDS parser that we could use as an inspiration

研究方向
Study the DDS format specification and the Renderdoc C++ implementation linked in the issue. Also review pillow's Python DDS parser to understand the conversion requirements. Then design a Cython module that wraps the parsing logic, ensuring compatibility with openage's converter pipeline. Check existing comments in the issue for any additional guidance from maintainers.
