pngcrush can be used to change the color encoding of an image. For example, if an image contains 10 colors but has a color palette of 256 entries (8-bit), pngcrush can be used to reduce the color palette to a 4-bit one and truncate the palette to 10 entries. pngcrush can also change the color type of the image.
In the case of decreasing the pixel number (scaling down), this usually results in a visible quality loss. From the standpoint of digital signal processing, the scaling of raster graphics is a two-dimensional example of sample-rate conversion, the conversion of a discrete signal from a sampling rate (in this case, the local sampling rate) to ...
In JPEG, 4:4:2 and 4:2:1 half the vertical resolution of Cb compared to 4:4:4 and 4:4:0. [19] In another version of 4:2:1, Cb horizontal resolution is half that of Cr (and a quarter of the horizontal resolution of Y). 4:1:0.5 or 4:1:0.25 are variants of 4:1:0 with reduced horizontal resolution on Cb, similar to VHS quality.
PNG support first appeared in 1997, in Internet Explorer 4.0b1 (32-bit only for NT), and in Netscape 4.04. [ 70 ] Despite calls by the Free Software Foundation [ 71 ] and the World Wide Web Consortium (W3C), [ 72 ] tools such as gif2png, [ 73 ] and campaigns such as Burn All GIFs, [ 74 ] PNG adoption on websites was fairly slow due to late and ...
High Efficiency Video Coding (HEVC or H.265) defines the Main 10 profile, which allows for 8 or 10 bits per sample with 4:2:0 chroma subsampling. [ 2 ] [ 4 ] [ 5 ] [ 30 ] [ 31 ] The Main 10 profile was added at the October 2012 HEVC meeting based on proposal JCTVC-K0109 which proposed that a 10-bit profile be added to HEVC for consumer ...
On the other hand, the Tandon 5 1 ⁄ 4-inch DD floppy format (1978) held 368,640 (which is 360×1024) bytes, but was advertised as "360 KB", following the 1024 convention. Early home computer systems would often advertise using the 1024 convention, hence the naming of the Commodore 64 , Commodore 128 , and the Amstrad CPC 464 .
