Appl. No.:

09/260986

Assignee:

Adobe Systems Incorporated - San Jose CA

International Classification:

G06K 932

US Classification:

382296, 382305

Abstract:

Methods and apparatus for managing a source image that is output in a rotated or skewed orientation to a raster buffer. The source image includes a plurality of source samples arranged in source rows having a source direction. The raster buffer is oriented in a destination space and receives the rotated or skewed image as a series of samples in rows defined by a destination direction. The raster buffer provides rows of samples to a rendering device for rendering scan lines for output on a raster device. The method includes determining an angle between the source direction and the destination direction and adjusting the organization of the source samples to align source samples in scan rows where each scan line can be rendered from the raster buffer using at most a predetermined small number of scan rows.

International Classification:

G06F007/00

US Classification:

707/100000

Abstract:

Techniques for moving a stub file (or any information that is used to recall migrated data) from an originating storage location to a destination storage location without recalling the migrated data corresponding to the stub file. The originating storage location and the destination storage location may be on storage unit allocated to the same server or allocated to different servers.

International Classification:

G11C029/00

US Classification:

714/769000

Abstract:

Techniques for maintaining data consistency in a storage environment. In a HSM controlled storage environment, techniques are provided for automatically detecting and correcting inconsistencies after a file system or a portion thereof has been restored from backup. The file system may store data files, tag files, and/or repository files that have been restored from backup.

International Classification:

US Classification:

345423

Abstract:

A method for defining a color gradient across a region in a display space that includes defining a bi-cubic patch enclosing the region. The bi-cubic patch includes four corners having a color associated therewith and four curves connecting pairs of the corners forming a closed loop. The four curves define the color gradient across the bi-cubic patch as a function of the four colors associated with the four corners of the bi-cubic patch. The method includes defining a unit square in parameter space including a mapping function from the unit square to the bi-cubic patch such that the corners of the bi-cubic patch map to the corners of the unit square. The color of every point in the unit square is a bi-cubic interpolation of the four colors associated with the four corners of the bi-cubic patch. The method includes clipping the bi-cubic patch for display of the region. In another aspect, the invention provides a method of accurately rendering color gradients across a bi-cubic patch that includes subdividing the bi-cubic patch into sub-patches until each side of a given sub-patch is a good approximation of a line and checking to determine if for all points inside of a given sub-patch the color associated with each point is sufficiently accurate.
