在windowsx系统,使用opencv读取图片时候报错,如下图所示:

这个错误是由于在读取文件时候没有加载Core.NATIVE_LIBRARY_NAME类
在类中加入静态代码块:
static {
//在使用OpenCV前必须加载Core.NATIVE_LIBRARY_NAME类,否则会报错
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
}
或者在main方法第一行添加一句:
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);

doc: update image codec configuration reference (add AVIF, fix JPEG XL) #28393
This PR updates the build configuration documentation to:
- Add AVIF to the supported format list (it was missing).
- Clarify that some codecs (AVIF, JPEG XL) do not support BUILD_* options because OpenCV does not bundle their source code.
- Update the description to include "write" capabilities for these formats.
