.SH NAME
|
|
png \- Portable Network Graphics (PNG) format
|
|
.SH DESCRIPTION
|
|
PNG (Portable Network Graphics) is an extensible file format for the
|
|
lossless, portable, well-compressed storage of raster images. PNG provides
|
|
a patent-free replacement for GIF and can also replace many
|
|
common uses of TIFF. Indexed-color, grayscale, and truecolor images are
|
|
supported, plus an optional alpha channel. Sample depths range from
|
|
1 to 16 bits.
|
|
.br
|
|
|
|
PNG is designed to work well in online viewing applications, such as the
|
|
World Wide Web, so it is fully streamable with a progressive display
|
|
option. PNG is robust, providing both full file integrity checking and
|
|
fast, simple detection of common transmission errors. Also, PNG can store
|
|
gamma and chromaticity data for improved color matching on heterogeneous
|
|
platforms.
