* Soporte para los ficheros .ecw de ErMapper |
| 74 | 75 |
* |
| 76 |
* NOTA: El SDK que ermapper ha puesto a disposici?n del p?blico en java |
|
| 77 |
* es una versi?n 2.45, de 19/11/2001. Est? implementada usando JNI que |
|
| 78 |
* se apoya en tres librer?as din?micas (dll), y presenta deficiencias |
|
| 79 |
* muy graves a la hora de acceder a la informaci?n. Hasta el momento |
|
| 80 |
* hemos detectado 3 de ellas: |
|
| 81 |
* 1?.- No soporta ampliaciones superiores a 1:1. si se intenta acceder |
|
| 82 |
* a un ecw con un zoom mayor da una excepci?n del tipo |
|
| 83 |
* com.ermapper.ecw.JNCSInvalidSetViewException, que de no ser tenida encuenta |
|
| 84 |
* acaba tirando abajo la m?quina virtual de java. |
|
| 85 |
* 2?.- La longitud m?xima de l?nea que adminte el m?todo readLineRGBA es |
|
| 86 |
* de unos 2500 pixeles, lo que hace el uso para la impresi?n en formatos |
|
| 87 |
* superiorea a A4 a 300 ppp o m?s inviable. |
|
| 88 |
* 3?.- La actualizaci?n progresiva usando el interface JNCSProgressiveUpdate |
|
| 89 |
* con el JNCSFile hace que el equipo genere un error severo y se apague. Este |
|
| 90 |
* error imposibilita esta t?cnica de acceso a ECW. |
