Said to be *very* crude), unless 'GTIFF_RAW:' is specified before the filename. In that later case, the CMYK bands will be presented. Also add support for translating to a CMYK TIFF too : the source dataset must have CMYK bands. No colorspace translation is done

  • Fix GTiffOddBitsBand::IWriteBlock with GDT_UInt16/32; Error properly with GDT_Float32; Support creating files with NBITS>8; Handle NBITS=1 IReadBlock/IWriteBlock in GTiffOddBitsBand; Prevent subtle IReadBlock/IWriteBlock round-tripping bug for NBITS<8 (#2360)
  • Set the TIFFTAG_COMPRESSION compression before asking the default strip size, so that in the case of JPEG compression, the correct strip height is selected (either 8 or 16). Tested with libtiff-3.8.2 and internal libtiff
  • Prevent crash on tiff_ovr_9 when JPEG-In-TIFF support is not built
  • In GTiffDataset::Create(), set TIFFTAG_JPEGCOLORMODE=JPEGCOLORMODE_RGB when creating a TIFF with COMPRESS=JPEG and PHOTOMETRIC=YCBCR; In Crystalize(), backup the value of TIFFTAG_JPEGCOLORMODE and set it again after writing the directory (#2645)
  • Handle more gracefully the case where we open or create a TIFF file with a compression method not built in libtiff (use of TIFFIsCODECConfigured)

  • Prevent crash when disk is full
  • Add detection of big-endian bigtiffs when BIGTIFF_SUPPORT is *NOT* defined
  • Add missing ScaleAtCenter parameter for Hotine Oblique Mercator when writing the geotiff keys

  • add support for writing 1, 2 and 4 bit data (#2436)
  • Attempt to preserve PROJCS name in sMapInfo.proName, and to capture it as the PROJCS name when reading. This will hopefully preserve symbolic names like NAD_1983_StatePlane_Ohio_South_FIPS_3402_Feet instead of replacing them with something generic like "Lambert_Conformal_Conic" (#2422).
  • avoid reducing array sizes if writing them in random order (#2427)
  • Manually destroy bands in HFADataset destructor so that there is no chance

they will end up trying to write out cached information after the file has been closed. Loosely related to (#2524).

  • error out gracefully and early on attempts to write to readonly file (#2524)

SWIG Language Bindings

SWIG General :

SWIG C# related changes:

  • Fixed that passing null as the options parameter of Driver.CreateCopy causes access violation (#2185).
  • Added GDALCreateCopy sample application
  • Support for signing the GDAL C# assemblies (#2186)
  • Added raster specific tests
  • Reworked the wrapper implementation
  • Added the bandMap parameter to the C# Dataset.ReadRaster and Dataset.WriteRaster API.
  • Added a C# sample to demonstrate the GDALDatasetRasterIO operations.
  • Added Band.GetHistogram to the C# bindings
  • Sample application for Band.GetHistogram.
  • Added the GDALAdjustContrast sample to demonstrate the image correction at the C# side.
  • Added Dataset.GetGCPs, Dataset.SetGCPs and GCPsToGeoTransform in the C# bindings (bugs #2426, #1986 and #1677
  • Added support for using OGR.Layer in Gdal.Polygonize
  • Changed the behaviour to use OSR.SpatialReference and OSR.CoordinateTransformation instead of defining the same classes in the OGR namespace
  • Changed the scope from internal to public of the required functions

SWIG Python related changes:

  • Fix layer getitem bug (#2187)
  • add some sugar to ogr.DataSource.DeleteLayer to be able to take in either an index or a layer name. If you give it a name, it *will* loop through all of the layers on the datasource. This might be expensive depending on the driver.
  • add date/time fetching support to the generic GetField implementation... note this is not real 'datetime' support yet
  • a typemap for taking in lists of GDAL objects #2458
  • don't always return 0 for OGRErrs #2498
  • Added GetDefaultHistogram() with Python implementation
  • support for mingw Windows builds
  • Link with gdal_i.lib instead of gdal.lib when building with MSVC compiler. (#2578)

SWIG Perl

  • Added a more verbose description to the error message if projection method test fails. Skip testing parameters of International Map of the World projection since it fails (a bug?).
  • driver's create method's 2nd parameter, if given, is a listref
  • Support Cygwin by adding -lstdc++ to LIBS if OS is cygwin
  • Add GetDriver method as an alias to _GetDriver for DataSource. This fixes an unnoticed side-effect of rewrapping GetDriver for root class OGR.
  • force name to be a string for _GetLayerByName and make default for name 0
  • fix Layer::Schema
  • use perl hash also for fields in schema (the new API was not really implemented), add Schema method also for Feature
  • croak in Geometry::create unless type, wkt, wkb, or gml given
  • do not call UseExceptions when booting OGR wrappers since it is only done once when booting GDAL (of which OGR is a part), do not include inline functions from cpl_exceptions.i into OGR wrappers
  • add exception support as for OGR
  • use geometry factory methods in Geometry::create; accept also only coordinate parameters (i.e. auto-add 0 if needed) in Point method for Point type
  • Add wrappers for field types datetime and lists. Do not use the overloaded (field name) versions of the get/set functions.
  • GetField and SetField methods, which check for goodness of the field (name, index) and support dates, times, datetimes, and lists. In Row and Tuple the field value may be a listref.
  • Support HEXWKB in Geo::OGR::Geometry::create.
  • As* methods for Geometry as aliases for ExportTo; SpatialReference->create constuctor
  • made needed links from parameters to typemaps to make Get- and SetDefaultHistogram methods work in Perl

SWIG Java:

  • removed colortable from java bindings for now (#2231)
Note: See TracWiki for help on using the wiki.
