自定义滤镜 #45
Comments
啥…… 举个例子呢? |
最简单的颜色映射可以使用LUT图, 目前滤镜规则是支持的 |
你好,我用这个 方法: cgeFilterUIImage_MultipleEffects(srcImage, ruleString, 1.0f, nil); |
@bolagong 你是异步加载八个吗, 如果是八个线程就可能同时存在8份. |
你好,是图片的问题,我发现加载的图片质量越是高清的大图,加载滤镜的时候越消耗内存。我点击一下添加滤镜,内存就从48M左右直接飘升到117M左右,你可以告诉我怎么优化类似这个的问题吗 |
预览的时候不要用这么高分辨率的图, 使用小一点的图, 最好保存结果, 离屏渲染的时候再使用高清大图会比较好 |

基于 5 * 4 的颜色矩阵, 不知道如何转换, 才能自定义滤镜
