This image has partial transparency (254 possible levels of transparency between fully transparent and fully opaque). It can be transparent against any background despite being anti-aliased. Some image formats, such as PNG and TIFF, also allow partial transparency through an alpha channel, which solves the edge limitation problem.
PNG offers a variety of transparency options. With true-color and grayscale images either a single pixel value can be declared as transparent or an alpha channel can be added (enabling any percentage of partial transparency to be used). For paletted images, alpha values can be added to palette entries.
A color spectrum image with an alpha channel that falls off to zero at its base, where it is blended with the background color. 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. [ 1] It is often useful to render picture ...
Transparency can provide almost perfect camouflage for animals able to achieve it. This is easier in dimly-lit or turbid seawater than in good illumination. Many marine animals such as jellyfish are highly transparent. Comparisons of 1. opacity, 2. translucency, and 3. transparency; behind each panel (from top to bottom: grey, red, white) is a ...
See-through display. An optical combiner for a see-through display. A see-through display or transparent display is an electronic display that allows the user to see what is shown on the screen while still being able to see through it. The main applications of this type of display are in head-up displays, augmented reality systems, digital ...
WebP is a raster graphics file format developed by Google intended as a replacement for JPEG, PNG, and GIF file formats. It supports both lossy and lossless compression, [ 8] as well as animation and alpha transparency . Google announced the WebP format in September 2010, and released the first stable version of its supporting library in April ...
Reversal film. A single slide, showing a color transparency in a plastic frame. Slide projector, showing the lens and a typical double slide carrier. In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. [ 1] Instead of negatives and prints, reversal film is processed to ...
An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy compression or ...
