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

  • 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

  • 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)

  • 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)
  • Prevent writing 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)

  • Solved unwanted rounding in the pixel size, that resulted in wrong map size calculation.

  • 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.

  • 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

  • driver's create method's 2nd parameter, if given, is a listref

  • 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

  • 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
