%description

|
|
|
%{name} converts 24/32-bit RGBA PNG images to 8-bit palette with
|
|
|
|
|
alpha channel preserved. Such images are compatible with all modern web
|
|
|
|
|
browsers and a compatibility setting is available to help transparency
|
|
|
|
|
degrade well in Internet Explorer 6. Quantized files are often 40-70
|
|
|
|
|
percent smaller than their 24/32-bit version. %{name} uses the
|
|
|
|
|
median cut algorithm.
