Cannot load BMP image on RHEL-10 #2463
Description
Please use the below example and use any bmp image..
Environment:
Red Hat Enterprise Linux 10.0 (Coughlan)
Windowing System: Wayland
GTK: GTK3
It's fresh machine. I assume I miss something to render bmp image.
package org.eclipse.swt.examples.browserexample;
import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
public class SWTImageAbsolutePathExample {
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
shell.setText("SWT BMP Test");
shell.setSize(420, 320);
String imagePath = "/home/user/Downloads/swt_test_32bpp.bmp"; // <- change this
try {
Image image = new Image(display, imagePath);
Label label = new Label(shell, SWT.NONE);
label.setImage(image);
label.setBounds(20, 20, image.getBounds().width, image.getBounds().height);
} catch (Exception e) {
e.printStackTrace();
}
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
}
}

More data:
As i did debug the issue present at:
NativeImageLoader#load(ElementAtZoom<InputStream> streamAtZoom, ImageLoader imageLoader, int targetZoom)
The exception is thrown from this call at line 62:
C.memmove(buffer_ptr, data_buffer, data_buffer.length);
