54 <LI>support was added for registering new codecs external to the library |
|
55 and for overriding the codecs that are builtin to the library |
|
56 <LI>emulation support for the old <TT>DataType</TT> tag was improved |
|
57 <LI>suppport was added for the <TT>SMinSampleValue</TT> |
|
58 and <TT>SMaxSampleValue</TT> tags |
|
59 <LI>the library no longer ignores <TT>TileWidth</TT> and <TT>TileLength</TT> |
|
60 tags whose values are not a multiple of 16 (per the spec); this |
|
61 permits old, improperly written, images to be read |
|
62 <LI>the support for the <TT>Predictor</TT> tag was placed in a reusable |
|
63 module so that it can be shared by multiple codecs |
|
64 <LI>experimental compression support was added for the Deflate algorithm |
|
65 (using the freely available zlib package) |
|
66 <LI>a new routine, <TT>TIFFWriteBufferSetup</TT> was added a la the |
|
67 routine <TT>TIFFReadBufferSetup</TT> |
|
68 <LI>the DSO version of the library is now statically linked with the |
|
69 JPEG and Deflate libraries; this means applications that link against |
|
70 the DSO do not also need to link against these ancillary libraries |
