速成的报告图像规模可以缩小到伙伴关系中。 NET/GDI包含编码图像?
原标题:Firefox Pagespeed reporting image size can be reduced on ASP.NET/GDI encoded image?

我采用一种计算图象的方法:foo(Bitmap bmp){

页: 1 Save(Stream stream, ImageCodec) 信息-编码

基本encoder与以下伪装成:

foreach (var _encoder in ImageCodecInfo.GetImageEncoders())
{
  if (_encoder.mimetype=="image/png")
  {
   encoder = _encoder;
   break;
  }
}

平均寿命

 using (EncoderParameters encParams = new EncoderParameters(1))
            {
                encParams.Param[0] = new EncoderParameter(Encoder.Quality, quality);
                ...
                ...
            }

图像类型是否为jpeg或png,页数仍然大致如下:

Losslessly compressing xyz.png could save 207B (44% reduction). See optimized version or Save as.

任何人都能够提供任何见解? 我确信,这是一个专门专题的范畴,因此,这是一个黑暗的tab脚石。
