MrSID Raster SDK Release Notes

9.5.4 (released 11 January 2018)

On Windows, the library is built without /Zc:wchar_t- so wchar_t is now a compile defined type, which is the VS default behavior. The /Zc:wchar_t- option is not required to link with wide string methods in LTFileSpec.
Added LTIImage::getMetadataBlob(type, stream) to get XMP or EXIF metadata stored in MrSID, JPEG, and TIFF files.
BMPImageWriter supports writing images with an alpha band.
TIFFImageWriter now allows the the user to set the “endianness” of the output file.
Added utility methods:
- In LIIImage: Added getNumBandsWithoutAlpha()
- In LTIPixel: Added setNonAlphaSampleValuesFromDouble(), setSampleValuesFromPixel(), and setNonAlphaSampleValuesFromPixel()
- In LTIOStreamInf: Added readString()

Added support for reading floating point images saved to the MrSID Generation 4 format. These images are created with the quantization compression type, a lossy compression method that reduces the precision of pixel values in the image.
Added metadata tags for images created with the quantization compression method.

See the User Manual for information about multi-processor support. The TBB shared object must be distributed.

In MrSIDImageReader, MG3SingleImageReader, MG4SingleImageReader, MrSIDImageStageManager: Added getMaxWorkerThreads() and setMaxWorkerThreads(). See the User Manual for information about the multi-processor support.
In J2KImageReader: Added support for reading GMLJP2 files.
Removed support for Solaris.
In mrsiddecode and mrsidinfo: On Unix, lib/libgeos.so must be in LD_LIBRARY_PATH.
In LTIImageStage: Added getPipelineInfo() to query the pipeline for its properties. This will only affect persons that have derived subclasses of LTIImageStage, LTIImageFilter, or LTIImageReader.
In LTIImageReader: Added getSourceName() to improve some error messages. This will only affect persons that have derived subclasses of LTIImageReader.
In LTIScene: Added constructor that takes LTIGeomIntRect and magnification.
