vavi-image-jpegxl's Issues

Does it work in Windows? How to use it

github actions doesn't support m1 macos

intel mac homebrew's libjpeg-xl version is not 0.9.x

【HELP】JNA is not stable【WANTED】

JNI version

test:org.jpeg.jpegxl.wrapper.DecoderTest#test2 works well always.

JNA version

test:vavi.image.jpegxl.Test2#main succeeds sometimes and fails sometimes, not 100%

WHY?

i tried

• JxlDecoderCreate: PointerByReference -> Pointer . . . . . . nothing has been changed
• void*: char[] -> BufferedReader#allocateDirect -> Pointer . . . . . . nothing has been changed
• size_t*: long[] -> LongReference -> NativeLong . . . . . . nothing has been changed
• threading: none -> JxlResizableParallelRunner -> JxlThreadParallelRunner . . . . . . nothing has been changed
