decoding and caching should happen at image creation time? #2

Closed willice9527 closed 6 years ago

willice9527 commented 6 years ago

首先致敬诸位大神的开源精神 LKImageSystemDecoder里有些疑惑之处，还请指教： CFDictionarySetValue(option, kCGImageSourceShouldCacheImmediately, kCFBooleanFalse); kCGImageSourceShouldCacheImmediately 看了下默认即为false，而且不少优化的教程都表示先decode and caching 会减轻图片实际用于显示时cpu的解码压力。 不知此处有何其它考虑？

if (request.processorList.count == 0) { CFDictionarySetValue(option, kCGImageSourceShouldCacheImmediately, kCFBooleanFalse); } 这里确实写错了，应该为true。这里的逻辑是如果后续不进行图片处理则此处解码，否则此处不解码 谢谢提醒，已经修改 it should be true for no image processor。Thank you。
