Oracle Multimedia now provides new constructor functions for BLOBs and other sources for these object types:
ORDAudio
See ORDAudio Constructors for complete reference information about these ORDAudio constructor functions: ORDAudio for BLOBS and ORDAudio for Other Sources.
ORDDoc
See ORDDoc Constructors for complete reference information about these ORDDoc constructor functions: ORDDoc for BLOBS and ORDDoc for Other Sources.
ORDImage
See ORDImage Constructors for complete reference information about these ORDImage constructor functions: ORDImage for BLOBS and ORDImage for Other Sources.
ORDVideo
See ORDVideo Constructors for complete reference information about these ORDVideo constructor functions: ORDVideo for BLOBS and ORDVideo for Other Sources.
As a result, the following init( ) methods were not enhanced in Oracle Database 11g, Release 2 (11.2):
init( ) for ORDAudio
init( ) for ORDDoc
init( ) for ORDImage
init( ) for ORDVideo
init(srcType,srcLocation,srcName) for ORDAudio
init(srcType,srcLocation,srcName) for ORDDoc
init(srcType,srcLocation,srcName) for ORDImage
init(srcType,srcLocation,srcName) for ORDVideo
Note:
These init( ) methods are still available in Release 11.2, but Oracle recommends taking these actions:
Write new applications to use the new constructor functions.
Migrate existing applications from the init( ) methods to the new constructor functions.
See Appendix H for more information about these methods.
Oracle Multimedia now supports adding watermarks that contain images or text to source images, thus preventing the misuse of copyrighted or trademarked images. See Section D.6 for more information about this feature.
Oracle Multimedia now provides these new image processing operators:
nometadata
Use the nometadata operator to process an image without encoding its image metadata in the resulting image. See Section D.3.6 for more information about this operator.
sharpen
Use the sharpen operator to improve the sharpness of an image. See Section D.3.11 for more information about this operator.
transparencyFillColor
Use the transparencyFillcolor operator to fill the transparent regions of PNG image file formats with color. See Section D.3.13 for more information about this operator.
Oracle Multimedia now supports the CMYK content format. See Section D.5 for more information about this feature.
Beginning with Oracle Database 11g, Release 2 (11.2), the DICOM support in ORDImage objects that was introduced in Oracle Database 10g, Release 2 (10.2) was not enhanced. The DICOM support in ORDImage objects is still available in Release 11.2, but Oracle recommends taking the following actions for medical imaging applications.
For new applications:
Use the new DICOM support that was introduced in Oracle Database 11g, Release 1 (11.1).
For existing applications that use the DICOM support in ORDImage objects:
Migrate to the new DICOM support that was introduced in Release 11.1.
See Section J.3 for more information about the status of this feature and its enhancements.
