在《每天进步一点点：使用Python批量修改图片尺寸》一文中，我曾提到之所以选择使用OpenCV库而不是Pillow，是因为OpenCV库使用C++实现，而Pillow是纯Python实现，所以使用OpenCV会比Pillow高效一点点。 (图源：pixabay)

每天进步一点点：使用Python批量修改图片尺寸

话说O哥之前曾在帖子中提及过，旅游贴的每张照片都是精挑细选，再用Windows的画图软件（Paint）一张张修改尺寸后，才上传到HIVE上来，蠢得不得了。 (图源：pixabay) 之所以修改尺寸，是因为照片的原始尺寸太大，占用公用图床空间不说，上传下载都会很慢。上传的话我可以慢慢等，但是下载的话，就会影响大家的阅读体验了，所以合适的尺寸还是很重要的。
