08/03/2024, 4:30 PMHi all - don't mean to be a bother, I've been poking away at trying to get an image from OpenCV drawn on the screen in Jetpack Compose. I've gotten it into a ByteArray, installed the pixels in a skia bitmap and whenever I try drawing it either with drawImage() in a canvas or just Image() composable my entire program crashes with a native stack trace. Is there something obvious I'm missing here or that I'm forgetting to do? The array and bitmap looks to be valid and .readyToDraw reports true, I just can't draw it.. the JNI stuff is way over my head 😭
