Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut-away 3D models of each. Below: two-dimensional plots showing two of a model's three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case the outside surface of each cylinder; horizontal cross-sections (c, g) of constant HSL lightness or HSV value, in this case the slices halfway ...

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 ...
8-bit color graphics are a method of storing image information in a computer's memory or in an image file, so that each pixel is represented by 8 bits (1 byte). The maximum number of colors that can be displayed at any one time is 256 per pixel or 2 8. [1]
Other resolutions: 320 × 46 pixels | 640 × 92 pixels | 1,024 × 148 pixels | 1,280 × 185 pixels | 2,560 × 370 pixels. Original file (SVG file, nominally 644 × 93 pixels, file size: 3 KB) This is a file from the Wikimedia Commons .
This allows 32768 possible colors for each pixel. The popular Cirrus Logic graphics chips of the early 1990s made use of the spare high-order bit for their so-called "mixed" video modes: with bit 15 clear, bits 0 through 14 would be treated as an RGB value as described above, while with bit 15 set, bit 0 through 7 would be interpreted as an 8 ...
Pixel-based scaling is almost exclusively used in games with two-dimensional graphics. With pixel-based scaling, the amount of content displayed on screen is directly tied to the rendering resolution. A larger horizontal resolution directly increases the horizontal field of view, and a larger vertical resolution increases the vertical field of ...
Equivalently, the size of the map selected should be equal to or larger than the ratio of source colors to target colors. For example, when quantizing a 24 bpp image to 15 bpp (256 colors per channel to 32 colors per channel), the smallest map one would choose would be 4×2, for the ratio of 8 (256:32).
