Core Image
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 layer), Quartz graphics rendering layer. The framework was later added to iOS in iOS 5. Overview Core Image abstracts the pixel-level manipulation process required when applying a filter to an image, making it simple for applications to implement image transformation capabilities without extensive coding. In a simple implementation, Core Image applies a single ''Image Filter'' to the pixel data of a given source to produce the transformed image. Each Image Filter specifies a single transform or effect, either built into Core Image or loaded from a plugin called an ''Image Unit''. Combined with preset or user-defined input parameters, the filter can be applied to the original pixel data without ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alpha Channel
In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite. Compositing is used extensively in film when combining computer-rendered image elements with live footage. Alpha blending is also used in 2D computer graphics to put rasterized foreground elements over a background. In order to combine the picture elements of the images correctly, it is necessary to keep an associated '' matte'' for each element in addition to its color. This matte layer contains the coverage information—the shape of the geometry being drawn—making it possible to distinguish between parts of the image where something was drawn and parts that are empty. Although the most basic operation of combining two images is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GEGL
The Generic Graphics Library (GEGL) is a programming library under development for image processing applications. It is mainly developed for GIMP in order to add support for higher bit depth images, and non-destructive editing. It was partially implemented in GIMP 2.6, with more added in 2.8, and is now a central part in 2.10. Many Filters are ready, but also much work in progress. Target is full support of all important filters in roadmap in Version 3.0. It is also used by GNOME'Photosangedl Design GEGL is modelled after a directed acyclic graph, where each ''node'' represents an image ''operation'' (called "operators" or "ops"), and each ''edge'' represents an ''image''. Operations can in general take several input images and give several output images, which corresponds to having several incoming edges (images) and several outgoing edges (images) at a given node (operation). The system uses an on-demand model, doing work only as required. This allows features such as havin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acorn (software)
Acorn is a raster graphic editor for macOS developed by August Mueller of Flying Meat Inc, based out of Mukilteo, Washington, United States. Acorn was first released on September 10, 2007 and was built upon the framework of a previous image editing application of Flying Meat Inc., FlySketch. Acorn makes extensive use of Apple's Core Image framework for its image processing. The native file format of Acorn is .acorn. Acorn combines vector drawing with bitmap editing, and has been described as an alternative to Photoshop. Key features of Acorn include image filters, a custom color picker, a brush designer, and image editing tools such as crop, erase, paint, select, pan, zoom, move, clone, smudge, dodge, and burn. Major Features *Layers-based editing *Layer masks and blending modes *Multi-layer screenshots *Nondestructive stackable filters *Curves and levels *Multi-stop live gradients *Scriptable * Automator support *Built in brush designer to create custom brushes *Photoshop ...

Affine Transformation
In Euclidean geometry, an affine transformation or affinity (from the Latin, '' affinis'', "connected with") is a geometric transformation that preserves lines and parallelism, but not necessarily Euclidean distances and angles. More generally, an affine transformation is an automorphism of an affine space (Euclidean spaces are specific affine spaces), that is, a function which maps an affine space onto itself while preserving both the dimension of any affine subspaces (meaning that it sends points to points, lines to lines, planes to planes, and so on) and the ratios of the lengths of parallel line segments. Consequently, sets of parallel affine subspaces remain parallel after an affine transformation. An affine transformation does not necessarily preserve angles between lines or distances between points, though it does preserve ratios of distances between points lying on a straight line. If is the point set of an affine space, then every affine transformation on can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiply Blends
Blend modes (alternatively blending modes or mixing modes) in digital image editing and computer graphics are used to determine how two layers are blended with each other. The default blend mode in most applications is simply to obscure the lower layer by covering it with whatever is present in the top layer (see alpha compositing); because each pixel has numerical values, there also are many other ways to blend two layers. Most graphics editing programs, such as Adobe Photoshop and GIMP, allow users to modify the basic blend modes, for example by applying different levels of opacity to the top "layer". The top "layer" is not necessarily a layer in the application; it may be applied with a painting or editing tool. The top "layer" also is called the "blend layer" and the "active layer". In the formulas shown on this page, values go from 0.0 (black) to 1.0 (white). ''Normal'' blend mode This is the standard blend mode which uses the top layer alone, without mixing its colors with ...

Quartz Compositor
Quartz Compositor is the display server (and at the same time the compositing window manager) in macOS. It is responsible for presenting and maintaining rasterized, rendered graphics from the rest of the Core Graphics framework and other renderers in the Quartz technologies family. Overview The bitmap output from Quartz 2D, OpenGL, Core Image, QuickTime, or other process is written to a specific memory location, or ''backing store''. The Compositor then reads the data from the backing stores and assembles each into one image for the display, writing that image to the frame buffer memory of the graphics card. Quartz Compositor only accepts raster data, and is the only process that can directly access the graphics frame buffer. In managing individual windows, Quartz Compositor accepts a bitmap image of the window's contents from its renderer, along with its position. The choice of the renderer is up to the individual application, although most use Quartz 2D. Quartz Composi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GMA X3100
The Intel Graphics Media Accelerator (GMA) is a series of integrated graphics processors introduced in 2004 by Intel, replacing the earlier Intel Extreme Graphics series and being succeeded by the Intel HD and Iris Graphics series. This series targets the market of low-cost graphics solutions. The products in this series are integrated onto the motherboard, have limited graphics processing power, and use the computer's main memory for storage instead of a dedicated video memory. They were commonly found on netbooks, low-priced laptops and desktop computers, as well as business computers which do not need high levels of graphics capability. In early 2007, about 90% of all PC motherboards sold had an integrated GPU. History The GMA line of GPUs replaces the earlier Intel Extreme Graphics, and the Intel740 line, the latter of which was a discrete unit in the form of Accelerated Graphics Port, AGP and Conventional PCI, PCI cards with technology that evolved from companies Real3D a ...
