Preview offers basic image correction tools using Core Image processing technology implemented in macOS, and other features like shape extraction, color extraction, cropping, and rotation tools. When annotating images, Preview uses vector shapes and text until the image is rasterized to JPEG, PNG or another bitmap format.
Apple Software Restore or asr is a command line utility in Mac OS X used to apply a DMG disk image to a selected partition or mount point on a file system. It is often used for cloning large numbers of Macintosh computers. Apple Software Restore can read an image locally or from a server via HTTP or its own multicast asr:// URI.
Target Disk Mode (sometimes referred to as TDM or Target Mode) is a boot mode unique to Macintosh computers. When a Mac that supports Target Disk Mode [1] is started with the 'T' key held down, its operating system does not boot. Instead, the Mac's firmware enables its drives to behave as a SCSI, FireWire, Thunderbolt, or USB-C external mass ...
[1] [2] The image of the written text may be sensed "off line" from a piece of paper by optical scanning (optical character recognition) or intelligent word recognition. Alternatively, the movements of the pen tip may be sensed "on line", for example by a pen-based computer screen surface, a generally easier task as there are more clues available.
Core Image is a pixel-accurate, near-realtime, non-destructive image processing technology in Mac OS X. Implemented as part of the QuartzCore framework of Mac OS X 10.4 and later, Core Image provides a plugin-based architecture for applying filters and effects within the Quartz graphics rendering layer. [1] The framework was later added to iOS ...
Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...
In the earlier implementations of Document Capture Software, the technology focused solely on the digitization and capture of information from paper documents. Document images were acquired from document scanners via TWAIN/ISIS drivers. Only image-based file formats like TIF, JPG, and BMP were typically compatible with these solutions.
Pen computing refers to any computer user-interface using a pen or stylus and tablet, over input devices such as a keyboard or a mouse.. Historically, pen computing (defined as a computer system employing a user-interface using a pointing device plus handwriting recognition as the primary means for interactive user input) predates the use of a mouse and graphical display by at least two ...
