/**

46 |
* Soporte para los ficheros .ecw de ErMapper.
|
47 |
* <br>
|
48 |
* NOTA: El SDK que ermapper ha puesto a disposici?n del p?blico en java
|
49 |
* es una versi?n 2.45, de 19/11/2001. Est? implementada usando JNI que
|
50 |
* se apoya en tres librer?as din?micas (dll), y presenta deficiencias
|
51 |
* muy graves a la hora de acceder a la informaci?n. Hasta el momento
|
52 |
* hemos detectado 3 de ellas:<BR>
|
53 |
* 1?.- No soporta ampliaciones superiores a 1:1. si se intenta acceder
|
54 |
* a un ecw con un zoom mayor da una excepci?n del tipo
|
55 |
* com.ermapper.ecw.JNCSInvalidSetViewException, que de no ser tenida encuenta
|
56 |
* acaba tirando abajo la m?quina virtual de java.<BR>
|
57 |
* 2?.- La longitud m?xima de l?nea que adminte el m?todo readLineRGBA es
|
58 |
* de unos 2500 pixeles, lo que hace el uso para la impresi?n en formatos
|
59 |
* superiorea a A4 a 300 ppp o m?s inviable.<BR>
|
60 |
* 3?.- La actualizaci?n progresiva usando el interface JNCSProgressiveUpdate
|
61 |
* con el JNCSFile hace que el equipo genere un error severo y se apague. Este
|
62 |
* error imposibilita esta t?cnica de acceso a ECW.<BR>
|
63 |
* <br>
|
64 |
* Para saltarnos la limitaci?n del bug#1 pedimos la ventana correspondiente al zoom 1:1 para
|
65 |
* el view que nos han puesto, y la resizeamos al tama?o que nos pide el usuario.<br>
|
66 |
* Como consecuencia del bug#2, para tama?os de ventana muy grandes (los necesarios
|
67 |
* para imprimir a m?s de A4 a 300DPI), hay que hacer varias llamadas al fichero con
|
68 |
* varios marcos contiguos, y los devolvemos 'pegados' en una sola imagen (esto se
|
69 |
* realiza de manera transparente para el usuario dentro de la llamada a updateImage.<br>
