J'essaie de combiner l'image tiff et le fichier de formes et je veux le montrer. Pour cela, j'utilise GeoTiff et je suis coincé que mon fichier tiff est maintenant affiché. Shapefile s'affiche correctement, mais l'image tiff, qui n'a qu'un seul indice de bande et d'échelle de gris, n'est pas affichée pour une raison quelconque. Je reçois un message d'avertissement comme ci-dessous.AVERTISSEMENT Utilisation possible de la projection "Transverse_Mercator" en dehors de sa zone valide
2016-08-04T12: 43: 06.456 + 0530 AVERTISSEMENT Utilisation de la projection "Transverse_Mercator" en dehors de sa zone de validité. Latitude 180 ° 00.0'S est hors limites (± 90 °).
Comment puis-je supprimer ce message?

Je viens de passer deux fichiers ci-dessous le code
public MapImagePanel() {
this.setLayout(new BorderLayout(0, 0));
this.setBackground(Color.BLUE);
this.setPreferredSize(new Dimension(720, 360));
this.setBlueMarble(new File("E:/tifffilename.TIFF"));
this.setBorderShape(new File("E:/shapefilename.shp"));
try {
this.displayLayers();
} catch (Exception e) {
e.printStackTrace();
}
}
Voici comment j'utiliser cette classe dans la classe principale
//see output in main method
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
MapImagePanel panel = new MapImagePanel();
panel.setPreferredSize(new Dimension(1024,768));
panel.setVisible(true);
frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);
frame.show();
Le message d'erreur est assez clair. Qu'est-ce que tu ne comprends pas? – Raedwald
Quelle ligne provoque ce message dans mon code? –
Ce n'est pas seulement un message d'erreur, cela signifie beaucoup de choses dans la zone géologique. Mieux vaut passer par ma réponse. –
