    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 ...

    Successive paper sizes in the series (A1, A2, A3, etc.) are defined by halving the area of the preceding paper size and rounding down, so that the long side of A(n + 1) is the same length as the short side of An. Hence, each next size is nearly exactly half the area of the prior size. So, an A1 page can fit two A2 pages inside the same area.

    Pixel aspect ratio 1:1 Pixel aspect ratio 2:1. A Pixel aspect ratio (often abbreviated PAR) is a mathematical ratio that describes how the width of a pixel in a digital image compared to the height of that pixel. Most digital imaging systems display an image as a grid of tiny, square pixels.

    A1, A2, A3, A4 and non-ISO sizes as GOST 3450-60 formats. A standard for technical drawings from 1960, GOST 3450, [15] introduces alternative numeric format designations to deal with very high or very wide sheets. These 2-digit codes are based upon A4 = "11": The first digit is the factor the longer side (297 mm) is multiplied by and the second ...

    The display aspect ratio (DAR) is calculated from the physical width and height of a display, measured each in inch or cm (Display size). The pixel aspect ratio (PAR) is calculated from the width and height of one pixel. The storage aspect ratio (SAR) is calculated from the numbers of pixels in width and height stated in the display resolution.

    The second-generation Macintosh, launched in 1987, came with colour (and greyscale) capability as standard, at two levels, depending on monitor size—512×384 (1/4 of the later XGA standard) on a 12" (4:3) colour or greyscale (monochrome) monitor; 640×480 with a larger (13" or 14") high-resolution monitor (superficially similar to VGA, but at ...

    An image that is 2048 pixels in width and 1536 pixels in height has a total of 2048×1536 = 3,145,728 pixels or 3.1 megapixels. One could refer to it as 2048 by 1536 or a 3.1-megapixel image. The image would be a very low quality image (72ppi) if printed at about 28.5 inches wide, but a very good quality (300ppi) image if printed at about 7 ...
