Tiff Class Enhancements
The Tiff class includes the following enhancements.
Tiff Class Now Excludes Reading OJPEG Format Image Data
You can no longer read YCbCr OJPEG ("old-style" JPEG compression) TIFF images. The
Tiff object was not intended to work with OJPEG data but some TIFF files contain data
in this format. Reading this data could cause LibTIFF to terminate.
Compatibility Considerations
To read OJPEG image data, use the imread function. Note that the imread function
transforms the image data into the RGB colorspace.
Additional Reading and Writing Capabilities
The Tiff class includes the following additional capabilities:
• Writing image data that use 16-bit colormaps (palettes)
• Reading and writing LogL and LogLUV High Dynamic Range (HDR) images. To write
a LogL or LogLUV image, you must use the new SGILogDataFmt property.
MATLAB Adds Support for Creating JPEG 2000 Files
You can now use the imwrite function to create a JPEG 2000 file and write data to the
file. The imwrite function supports format-specific parameters that let you specify the
mode, compression ratio, and other characteristics.
Sealed No Longer Listed as meta.property Class Property
While class properties do not have a Sealed attribute, the meta.property class listed
Sealed as a property. Sealed is no longer listed as a meta.property class property.
