I want to check if particular string is present in the image. Is that possible? Is pngj can do that?

我的文件将包含一个图形和一些图例.我想检查图例是否正确.

My file will contain a graph and some legends. I want to check the if the legends are correct.

推荐答案

不，您不能使用pngj做到这一点.在PNG图像中可见的文本不会在内部存储为文本.如果您希望识别文本，则需要 OCR 软件.

No, you can't do that with pngj. The text that is visible in the PNG image is not internally stored as text. You will need OCR software if you wish to identify the text.

但是，如果能够以另一种更易于计算机解析的格式获取数据，那就更好了.

However it would be much better if you could get the data in another format that is easier to parse by a computer.
