|

| 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
