React Native 中的图像处理？

[英]Image manipulation in React Native?

原文 2022-01-19 14:02:57 3 1 javascript/ react-native/ image-manipulation

I need to create a simple mobile app in React Native for manipulate images from the gallery and the camera.我需要在 React Native 中创建一个简单的移动应用程序来操作图库和相机中的图像。 I searched it everywhere, but didn't found any proper solution for this, just libraries for cropping/rotating/etc.我到处搜索，但没有找到任何合适的解决方案，只是用于裁剪/旋转/等的库。

I only want to put own filter on pictures (like a simple national flag with opacity).我只想在图片上添加自己的过滤器（比如不透明的简单国旗）。

Is there any library for bare/expo RN to edit image pixels, or is there any solution to convert an image to a bitmap then convert back to an image and save it?是否有任何用于 bare/expo RN 的库来编辑图像像素，或者是否有任何解决方案可以将图像转换为 bitmap 然后转换回图像并保存？
