Porting problems

Newbie & Debugging Questions

I’m trying to port my game to linux,
and it seems there is a problem loading the textures…

Here is the error:


java.lang.IllegalArgumentException: Width (-1) and height (-1) must be > 0
        at java.awt.image.SampleModel.<init>(Unknown Source)
        at java.awt.image.ComponentSampleModel.<init>(Unknown Source)

        at srw.FrameLauncher.run(FrameLauncher.java:167)
        at srw.FrameLauncher.main(FrameLauncher.java:89)

Here is the code which calls it…


      public void loadTextures() 

      {

            textures.put(T_FONT, loadTexture(T_FONT));

            buildFont();

            

            textures.put(T_BUTTON_1, loadTexture(T_BUTTON_1));

            textures.put(T_GRASS, loadTexture(T_GRASS));

            textures.put(T_GRASS2, loadTexture(T_GRASS2));

            textures.put(T_STONE1, loadTexture(T_STONE1));

            textures.put(T_STONE2, loadTexture(T_STONE2));

            textures.put(T_METAL1, loadTexture(T_METAL1));

            textures.put(T_METAL2, loadTexture(T_METAL2));

            textures.put(T_GREY1, loadTexture(T_GREY1));

            textures.put(T_GREY2, loadTexture(T_GREY2));

            textures.put(T_PARTICLE, loadTexture(T_PARTICLE));

            textures.put(T_MENU, loadTexture(T_MENU));

            

      }



      private final Integer loadTexture(String path) 

      {

            Image image = (new javax.swing.ImageIcon(path)).getImage();



            // Exctract The Image

            BufferedImage tex = new BufferedImage(image.getWidth(null), image.getHeight(null), BufferedImage.TYPE_3BYTE_BGR);

The last line is the one that is crashes on…
and it seems to crash when it is trying to load Grey
its weird cause the other ones seems to load fine.

It seems the only files with problems are the ones I created
myself in MSPaintshop and then converted to PNG file using
ACDSee…

but all the other textures I’ve downloaded from the internet seems
to work fine. I don’t know what would be wrong.

Under windows the textures load perfectly.

If there are transperancy in the png files and you made them with ms paint, I know from experience that your problem is ms paint.
