更新日志

新的改变 OcrViewer 2.0 更新于 2019.1.18

我对OcrViewer进行了一些功能拓展与界面美化，除了标准的本地图片识别功能，我增加了如下几点新功能，帮助你更方便使用本工具，进而更好地识别图像中的文字：

全新的界面设计，将会带来全新的使用体验；

在创作中心设置你喜爱的代码高亮样式，Markdown 将代码片显示选择的高亮样式 进行展示；

增加了 截图识别 功能，你可以通过截取图片直接直接进行识别；

增加了图片预览功能，更加方便进行图文对比，减少容错；

增加了 清除图片预览 功能，可以清清除览的图片；

增加了 重新识别 等功能，如果不确定可以多次识别提高识别精确率；

下面是功能以及新界面展示
