Function Bug Fixes
dicomread No longer errors when reading files that contain extraneous pixel data;
instead, dicomread issues a warning message. However, if the file does
not contain enough pixel data, dicomread issues an error.
dicomwrite • No longer is case sensitive when parsing input parameters. For
example, you can specify either 'CreateMode' or 'createmode'.
• Preserves the full precision of data converted to decimal string
metadata. Previously, dicomwrite limited precision to six digits.
• No longer errors when writing files with metadata values that must
be stored as a decimal string or integer string. Now, when writing
private data attributes (attributes that are not listed in the DICOM
data dictionary), dicomwrite assigns the attributes the type UN
(for unknown) and writes the data to the file as a byte-for-byte copy
of its in-memory representation. Because dicomwrite writes the
file with explicit value representation (VR), the file might have a
different VR value, but the data will be the same.
• Includes the TriggerTime field for additional values of
ScanOptions, including 'CT'. Previously, dicomwrite only
included the TriggerTime attribute if the ScanOptions field
indicated a gated heart MR.
• No longer issues an Unsupported SOP class error message if,
when 'create' mode is specified, semantic verification is not
available for an information object. Instead, dicomwrite issues a
more helpful message indicating that it might be able to write the
data if the mode was 'copy', rather than 'create'. In 'copy'
mode, dicomwrite only performs syntactic checking, not semantic
verification. Consequently, dicomwrite can write many more types
of DICOM files in 'copy' mode than it can in 'create' mode. See
the dicomwrite reference page for important information about
data integrity.
Changes to Image Tool and Modular Interactive Tools
The following fixes have been made to the Image Tool and other modular interactive
tools:
• The Image Tool now always makes the Open and Import from Workspace options
available on its File menu. Previously, the Image Tool disabled these options if the
