Subject [jira] [Commented] (SANSELAN-48) Sanselan cannot read CCITT compressed TIFF files
Date Sat, 10 Dec 2011 10:25:40 GMT

    [ https://issues.apache.org/jira/browse/SANSELAN-48?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13166819#comment-13166819
] 

Damjan Jovanovic commented on SANSELAN-48:
------------------------------------------

I've committed a patch for compression=2, and this will be in the upcoming release.

compression=3 will have to wait - the compression=2 code should be adaptable for the 1D case,
but the 2D case still needs to be written.

compression=4 will also have to wait - I am not going to upgrade Sanselan to Java 1.5 for
the upcoming release, so Paul Wolfgang's patch can't be applied.

2 must be supported and types 3 and 4 are optional.
