24 bits almost always use 8 bits each of R, G, and B (8 bpc). As of 2018, 24-bit color depth is used by virtually every computer and phone display [citation needed] and the vast majority of image storage formats. Almost all cases of 32 bits per pixel assigns 24 bits to the color, and the remaining 8 are the alpha channel or unused.
Often known as truecolor and millions of colors, 24-bit color is the highest color depth normally used, and is available on most modern display systems and software. Its color palette contains (2 8) 3 = 256 3 = 16,777,216 colors. 24-bit color can be represented with six hexadecimal digits.
For example, a 640 × 480 pixel image with 24-bit color would occupy almost a megabyte of space: 640 × 480 × 24 = 7,372,800 bits = 921,600 bytes = 900 KiB. With vector images, the file size increases only with the addition of more vectors.
An entire class of operations [clarification needed] on binary images operates on a 3×3 window of the image. This contains nine pixels, so 2 9 or 512 possible values. . Considering only the central pixel, it is possible to define whether it remains set or unset, based on the surroundi
Visual impact of a jpeg compression on Photoshop on a picture of 4480x4480 pixels. For information, the uncompressed 24-bit RGB bitmap image below (73,242 pixels) would require 219,726 bytes (excluding all other information headers). The filesizes indicated below include the internal JPEG information headers and some metadata. For highest ...
With the predominance of 24-bit displays, the use of the full 16.7 million colors of the HTML RGB color code no longer poses problems for most viewers. The sRGB color space (a device-independent color space [ 23 ] ) for HTML was formally adopted as an Internet standard in HTML 3.2, [ 24 ] [ 25 ] though it had been in use for some time before that.
Whereas GIF is limited to 8-bit indexed color, PNG gives a much wider range of color depths, including 24-bit (8 bits per channel) and 48-bit (16 bits per channel) truecolor, allowing for greater color precision, smoother fades, etc. [50] When an alpha channel is added, up to 64 bits per pixel (before compression) are possible.
