when I add com.github.gotson.nightmonkeys:imageio-jaxl:0.2.0 I get an error about com.github.gotson.nightmonkeys:imageio-common:jar:0.2.0 missing.
I can't find it in maven central https://search.maven.org/search?q=g:com.github.gotson.nightmonkeys - maybe it was missed ?
First of all, this is a really awesome project: using the new Java 18 Foreign Linker API(instead of JNA) and adding support for JPEG XL to the normal Java ImageIO, meaning using/adopting this lib is really easy to do. You might want to make a post on r/Java to get some more people looking into it.
To the question, are there any plans/roadblocks/ETA for adding writing xlr files? Looking at komga, it's probably the end goal to be able to also read in png files and send them to the client in jxr to save bandwidth on mobile devices.
I am experiencing an off-heap memory leak in my test application.
When reading many images, Heap size stays well below the max heap configured for the Application (for example 4GB), but when processing many HEIF images, java commit size grows into the tens of GBs of memory. The JVM dies after a while, because it cannot allocate more memory, as well as other applications on the PC due to memory starvation of the whole system.
imageio-common-0.6.2
imageio-heif-0.6.2
imageio-core-3.10.1
libheif 1.14
OpenJDK 21.0.3.9-hotspot
It is easy to reproduce with this test program:
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.imageio.stream.ImageInputStream;
import com.github.gotson.nightmonkeys.heif.imageio.plugins.HeifImageReader;
import com.github.gotson.nightmonkeys.heif.imageio.plugins.HeifImageReaderSpi;
public class HEIFReadLoop {
private HeifImageReaderSpi heifSpi = new HeifImageReaderSpi();
private HeifImageReader reader;
public static void main(String[] args) {
HEIFReadLoop l = new HEIFReadLoop();
}
public HEIFReadLoop() {
try {
reader = (HeifImageReader) heifSpi.createReaderInstance();
int counter = 0;
while (true) {
System.out.println("read image " + counter++);
BufferedImage image = readHeicImage(new File("test.heic"));
}
} catch (IOException e) {
e.printStackTrace();
return;
}
}
private BufferedImage readHeicImage(File file) throws IOException {
try (ImageInputStream input = ImageIO.createImageInputStream(file)) {
reader.reset();
reader.setInput(input);
BufferedImage result = reader.read(0);
reader.dispose();
return result;
}
}
}
Run with -Xmx256m given a sufficiently small .heic image.
When you run this test app, Heap size stays well below 256m for a small image.
But system memory used by the java process grows by about 150m each second, untill all available system RAM is consumed.
centos 怎么才能拿到libheif-dev那?
I tried to run komga with java 20, and I got this error:
2023-05-14 14:08:04.296 WARN 502417 --- [ main] c.g.g.n.j.i.plugins.JxlImageReaderSpi : Missing Foreign Linker API, plugin will be disabled. Try adding JVM arguments: --enable-preview
I'm already using this option and everything works correctly with java 19.
This is how I launch komga:
~ $ cat /bin/komga
#!/bin/sh
exec /usr/bin/java --enable-preview -Dforeign.restricted=permit -jar '/usr/share/java/komga/komga.jar' "$@"
Am I doing something wrong?
I tried to search the web, but google can't even find one page with "Missing Foreign Linker API".
