Description Dennis Payne 2006-01-15 09:13:45 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7

Description of problem:
I noticed that createImage doesn't create a BufferedImage so I modified my code to create a BufferedImage instead of using createImage.  Unfortunately this causes an exception when calling getGraphics.  I've included a simple example of the problem.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Compile this program with gcj -C

import java.awt.image.BufferedImage;
import java.awt.*;

class TestMe
  public static void main(String [] args)
    BufferedImage imgMonster = new BufferedImage(20, 20, BufferedImage.TYPE_INT_ARGB);
    Graphics gImg = imgMonster.getGraphics();
    gImg.fillRect(0, 0, 20, 20);

2. Run it 'gij TestMe'

Actual Results:  Exception in thread "main" java.lang.UnsatisfiedLinkError: initState
   at gnu.java.awt.peer.gtk.GdkGraphics2D.initState(int[], int, int) (/usr/lib/lib-gnu-java-awt-peer-gtk.so.6.0.0)
   at gnu.java.awt.peer.gtk.GdkGraphics2D.GdkGraphics2D(java.awt.image.BufferedImage) (/usr/lib/lib-gnu-java-awt-peer-gtk.so.6.0.0)
   at gnu.java.awt.peer.gtk.GdkGraphicsEnvironment.createGraphics(java.awt.image.BufferedImage) (/usr/lib/lib-gnu-java-awt-peer-gtk.so.6.0.0)
   at java.awt.image.BufferedImage.createGraphics() (/usr/lib/libgcj.so.6.0.0)
   at java.awt.image.BufferedImage.getGraphics() (/usr/lib/libgcj.so.6.0.0)
   at TestMe.main(java.lang.String[]) (Unknown Source)
   at gnu.java.lang.MainThread.call_main() (/usr/lib/libgcj.so.6.0.0)
   at gnu.java.lang.MainThread.run() (/usr/lib/libgcj.so.6.0.0)

Expected Results:  Nothing.  It should run without error.

Comment 1 Thomas Fitzsimmons 2006-02-03 20:28:51 EST
Graphics2D requires the Cairo backend which we didn't enable for FC4 because
Cairo was missing.  I'll look into enabling it for FC5.
Comment 2 Thomas Fitzsimmons 2006-03-02 11:41:16 EST
I couldn't enable this in time for FC5 final.  I'll try to do a merge of the
updated GUI packages from GNU Classpath to libgcj, for a future FC5 gcc update.
Comment 3 Thomas Fitzsimmons 2006-07-26 13:58:09 EDT
Fixed in Rawhide by libgcj backport.
