Seashore (software)
Seashore is a free and open-source image editor for macOS, similar to Photoshop/GIMP, with a simpler Cocoa user interface. Seashore uses GIMP's native file format, XCF, and has support for a handful of other graphics file formats, including full support for TIFF, PNG, JPEG, JPEG2000, and HEIC and read-only support for BMP, PDF, SVG and GIF. Seashore offers fewer features than Photoshop/GIMP, but is intended to be easy-to-use and to run natively on macOS. It includes layers and alpha channel support, gradients and transparency effects, anti-aliased brushes, tablet support and plug-in filters. After several years without maintenance, development was restarted by Robert Engels in 2017 to allow it to run on newer versions of macOS. Seashore version 3.16 was released in December 2022 and is considered to be stable. The latest release is distributed via the Apple Mac App Store. Features Seashore has many of the basic features found in graphics editing software, including: * Full ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Objective-C
Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. Originally developed by Brad Cox and Tom Love in the early 1980s, it was selected by NeXT for its NeXTSTEP operating system. Due to Apple macOS’s direct lineage from NeXTSTEP, Objective-C was the standard programming language used, supported, and promoted by Apple for developing macOS and iOS applications (via their respective APIs, Cocoa and Cocoa Touch) until the introduction of the Swift programming language in 2014. Objective-C programs developed for non-Apple operating systems or that are not dependent on Apple's APIs may also be compiled for any platform supported by GNU GCC or LLVM/Clang. Objective-C source code 'messaging/implementation' program files usually have filename extensions, while Objective-C 'header/interface' files have extensions, the same as C header files. Objective-C++ files are denoted with a file extension. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plug-in (computing)
In computing, a plug-in (or plugin, add-in, addin, add-on, or addon) is a software component that adds a specific feature to an existing computer program. When a program supports plug-ins, it enables customization. A theme or skin is a preset package containing additional or changed graphical appearance details, achieved by the use of a graphical user interface (GUI) that can be applied to specific software and websites to suit the purpose, topic, or tastes of different users to customize the look and feel of a piece of computer software or an operating system front-end GUI (and window managers). Purpose and examples Applications may support plug-ins to: * enable third-party developers to extend an application * support easily adding new features * reduce the size of an application by not loading unused features * separate source code from an application because of incompatible software licenses. Types of applications and why they use plug-ins: * Digital audio workstation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comparison Of Raster Graphics Editors
Raster graphics editors can be compared by many variables, including availability. List General information Basic general information about the editors: creator, company, license, etc. Operating system support The operating systems on which the editors can run natively, that is, without emulation, virtual machines or compatibility layers. In other words, the software must be specifically coded for the operation system; for example, Adobe Photoshop for Windows running on Linux with Wine does not fit.

Paintbrush (software)
Paintbrush is a raster image editor for Mac OS X. It aims to replace MacPaint, an image editor for the classic Mac OS last released in 1988. It also is an alternative to MS Paint. It has basic raster image editing capabilities and a simple interface designed for ease of use. It exports as PNG, JPG, BMP, GIF, and TIFF. The application also is often used for pixel art because of its grid option, and is not made for large scale images or GIMP or Photoshop-like editing on pictures or photographs. Features and capabilities It includes a simple brush-based freehand drawing tool, an eraser tool, a select tool, a freehand spray can tool which applies several pixels onto an area instead of just one, a fill tool, a "bomb" tool that clears the page, a line tool, a curve tool, square, circle/oval, and rounded square tools, text tool, a color picker/eyedropper, and a zoom in/zoom out tool.

Image Histogram
An image histogram is a type of histogram that acts as a graphical representation of the tonal distribution in a digital image. It plots the number of pixels for each tonal value. By looking at the histogram for a specific image a viewer will be able to judge the entire tonal distribution at a glance. Image histograms are present on many modern services. Photographers can use them as an aid to show the distribution of tones captured, and whether image detail has been lost to blown-out highlights or blacked-out shadows. This is less useful when using a raw image format, as the dynamic range of the displayed image may only be an approximation to that in the raw file. The horizontal axis of the graph represents the tonal variations, while the vertical axis represents the total number of pixels in that particular tone. The left side of the horizontal axis represents the dark areas, the middle represents mid-tone values and the right hand side represents light areas. The vertical ...

Color Histogram
In image processing and photography, a color histogram is a representation of the distribution of colors in an image. For digital images, a color histogram represents the number of pixels that have colors in each of a fixed list of color ranges, that span the image's color space, the set of all possible colors. The color histogram can be built for any kind of color space, although the term is more often used for three-dimensional spaces like RGB or HSV. For monochromatic images, the term intensity histogram may be used instead. For multi-spectral images, where each pixel is represented by an arbitrary number of measurements (for example, beyond the three measurements in RGB), the color histogram is ''N''-dimensional, with N being the number of measurements taken. Each measurement has its own wavelength range of the light spectrum, some of which may be outside the visible spectrum. If the set of possible color values is sufficiently small, each of those colors may be placed o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lasso Tool
The lasso (or "free form selection") is an editing tool available, with minor variations, in most digital image editing software. It is often accessed from the standard main menu (in Photoshop, Paint Tool SAI, and GIMP, as common examples), by clicking the icon of a dotted line shaped like a rope lasso, from which the common name arises. Standard operation The lasso tool operates on the active layer of an image, and is used by clicking and dragging to trace the edges of a selection. Most software supports multiple closed contours, which can be selected by crossing over the edge path multiple times. It is also typically not necessary to close the shape: releasing the mouse button triggers the software to close any open loop(s) automatically. The area enclosed by the cursor path will remain selected and open to various transform operators (shift, scale, cut, copy, and paste, for example) until elsewhere in the image is clicked. At this point, the lassoed selection will merge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Image Gradient
An image gradient is a directional change in the intensity or color in an image. The gradient of the image is one of the fundamental building blocks in image processing. For example, the Canny edge detector uses image gradient for edge detection. In graphics software for digital image editing, the term gradient or color gradient is also used for a gradual blend of color which can be considered as an even gradation from low to high values, as used from white to black in the images to the right. Another name for this is ''color progression''. Mathematically, the gradient of a two-variable function (here the image intensity function) at each image point is a 2D vector with the components given by the derivatives in the horizontal and vertical directions. At each image point, the gradient vector points in the direction of largest possible intensity increase, and the length of the gradient vector corresponds to the rate of change in that direction. Since the intensity function of a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channel (digital Image)
Color digital images are made of pixels, and pixels are made of combinations of primary colors represented by a series of code. A channel in this context is the grayscale image of the same size as a color image, made of just one of these primary colors. For instance, an image from a standard digital camera will have a red, green and blue channel. A grayscale image has just one channel. In geographic information systems, channels are often referred to as raster bands. Another closely related concept is feature maps, which are used in convolutional neural networks. Overview In the digital realm, there can be any number of conventional primary colors making up an image; a channel in this case is extended to be the grayscale image based on any such conventional primary color. By extension, a channel is any grayscale image of the same dimension as and associated with the original image. ''Channel'' is a conventional term used to refer to a certain component of an image. In reality, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Layers (digital Image Editing)
Layers are used in digital image editing to separate different elements of an image. A layer can be compared to a transparency on which imaging effects or images are applied and placed over or under an image. Today they are an integral feature of image editor. Layers were first commercially available in Fauve Matisse (later Macromedia xRes), and then available in Adobe Photoshop 3.0, in 1994, but today a wide range of other programs, such as Photo-Paint, Paint Shop Pro, GIMP, Paint.NET, StylePix, and even batch processing tools also include this feature. In vector image editors that support animation, layers are used to further enable manipulation along a common timeline for the animation; in SVG images, the equivalent to layers are "groups". Layer types There are different kinds of layers, and not all of them exist in all programs. They represent a part of a picture, either as pixels or as modification instructions. They are stacked on top of each other, and depending on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
