pngquant批量PNG圖像轉(zhuǎn)換庫(kù)

pngquant 是一個(gè)批次轉(zhuǎn)換數(shù)值化和高頻振動(dòng)真彩PNG圖像的實(shí)用程序,特別是那些有一個(gè)完整的alpha通道,歸結(jié)為“rgba調(diào)色板”P(pán)NG(即。,tRNS PLTE +在PNG的說(shuō)法)。這些圖像通常是兩到四次小于整個(gè)32位版本,和局部透明度是很好地保存下來(lái)。這使得pngquant特別是有用的對(duì)網(wǎng)站和PlayStation 2發(fā)展,其中一個(gè)紋理格式是基于rgba調(diào)色板(盡管不是png壓縮)。

pngquant is a batch conversion utility to quantize and dither truecolor PNG images, especially those with a full alpha channel, down to "RGBA-palette" PNGs (i.e., PLTE + tRNS in PNG parlance). Such images are usually two to four times smaller than the full 32-bit versions, and partial transparency is preserved quite nicely. This makes pngquant especially useful both for Web sites and for PlayStation 2 development, where one of the texture formats is RGBA-palette-based (though not PNG-compressed).
