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.
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 produce transparencies or diapositives (abbreviated as "diafilm" or "dia" in some languages like German , Romanian or Hungarian ).
On small images, GIF can achieve greater compression than PNG (see the section on filesize, below). On most images, except for the above case, a GIF file has a larger size than an indexed PNG image. PNG gives a much wider range of transparency options than GIF, including alpha channel transparency.
A dark image on the negative is of higher density than a more transparent image. Most films are affected by the physics of silver grain activation (which sets a minimum amount of light required to expose a single grain) and by the statistics of random grain activation by photons. The film requires a minimum amount of light before it begins to ...
Therefore, the transparency is placed face up (toward the mirror and focusing lens), in contrast with a 35mm slide projector or film projector (which lack such a mirror) where the slide's image is non-reversed on the side opposite the focusing lens. A related invention for enlarging transparent images is the solar camera.
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 ...
In partnership with the IU Libraries Moving Image Archive, Jennifer and Jon Vickers present “The Moving Image Plays Itself” at 7 p.m. Sept. 7.
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]
