Abstract data type
A large object whose value is composed of binary data, and is stored outside of the database in an operating system file. Because they are outside of the database, BFILEs are read-only.
See BLOB.
Binary large object. Large objects are stored in the database tablespace in a way that optimizes space and provide efficient access. Only a pointer to the object is actually stored in the row.
A description of the image data, such as the pixel or color format.
Selecting the portion of an image within a specified rectangle and removing everything outside of that rectangle. See cutting.
Selecting the portion of an image within a specified rectangle to create a subimage. If the subimage is copied to a new image, the effect is a cut. If the subimage replaces the original, the effect is a crop. Use the process( ) or processCopy( ) procedures to cut or crop an image.
The mechanism by which clients, application-specific servers, and database servers can be easily and reliably extended.
Using a default constructor in an OCI call creates an empty instance of the constructor.
The file format of the image data, such as BMP or GIF.
Interface definition language
A graphic picture. The source could be a photograph, drawing, or generated image.
Changing the properties of an image, such as through scaling, rotation, or compression.
Large object. LOBs are used to hold large amounts of raw, binary data. Image Cartridge supports BLOB and BFILE LOBs.
A means for reducing the storage space required for an image. The decompressed image is bit-for-bit identical to the original.
A means for reducing the storage space required for an image. The decompressed image has less resolution than the original, although this might not be noticeable to the naked eye.
A fully integrated design integrating text, spatial, and image data. The architecture supports the design, development, installation, and integration of manageable components across entire organizations.
A database having both object-oriented and relational characteristics. Objects can be defined and stored, and then retrieved using standard relational methods.
Oracle Call Interface
Object data type
Changing the proportions of an image in one or both dimensions. To enlarge an image, scale by a factor greater than one. To shrink an image, scale by a factor between zero and one. Use the process( ) or processCopy( ) procedures to scale an image.
