CompressFormat(intnativeInt){ this.nativeInt=nativeInt; } finalintnativeInt; } PNG格式 表示以PNG压缩算法进行图像压缩,压缩后的格式可以是".png",是一种无损压缩。 全称:便携式网络图形(Portable Network Graphics,PNG),它是一种无损压缩的位图图形格式,支持索引、灰度、RGB三种颜色方案以及Alpha通道等特性。最高...
CompressFormat 指定Bitmap的压缩格式,可选择JPEG、PNG、WEBP int类型的quality 指定Bitmap的压缩品质,范围是0 ~ 100;该值越高,画质越高。0表示画质最差,100画质最高。 OutputStream 指定Bitmap的字节输出流。一般使用: ByteArrayOutputStream stream = new ByteArrayOutputStream(); ...
