The graphics display resolution is also known as the display mode or the video mode, although these terms usually include further specifications such as the image refresh rate and the color depth. The resolution itself only indicates the number of distinct pixels that can be displayed on a screen, which affects the sharpness and clarity of the ...
The eye's perception of display resolution can be affected by a number of factors – see image resolution and optical resolution. One factor is the display screen's rectangular shape, which is expressed as the ratio of the physical picture width to the physical picture height. This is known as the aspect ratio. A screen's physical aspect ratio ...
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.
The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. [29] 960H represents an increase in pixels of some 30% over standard D1 resolution, which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC). The increased resolution over D1 comes as a result of a longer ...
The PNG file format supports 8-bit (256 colors) paletted images (with optional transparency for all palette colors) and 24-bit truecolor (16 million colors) or 48-bit truecolor with and without alpha channel – while GIF supports only 8-bit palettes with a single transparent color. Compared to JPEG, PNG excels when the image has large ...
Image resolution is the level of detail of an image. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to ...
This is the highest resolution that generally can be displayed on analog computer monitors (most CRTs), and the highest resolution that most analogue video cards and other display transmission hardware (cables, switch boxes, signal boosters) are rated for (at 60 Hz refresh). 24-bit colour requires 9 MB of video memory (and transmission ...
A PNG file contains a single image in an extensible structure of chunks, encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. [7] PNG files have the ".png" file extension and the "image/png" MIME media type. [8]
