我目前正在学习编程,并且正在尝试将此库添加到ZopfliPNG。我想用它代替 Zopfli。我试图改变这个,但它不工作:
unsigned CustomPNGDeflate(unsigned char** out, size_t* outsize, const unsigned char* in, size_t insize, const LodePNGCompressSettings* 设置){ int 压缩级别 = 12; struct libdeflate_compressor* 压缩器; 压缩器 = libdeflate_alloc_compressor(compression_level); libdeflate_deflate_compress(压缩器,in,insize,out,outsize); libdeflate_free_compressor(压缩器); 返回0; }
在编译期间,我有这个:
错误:从 'size_t* {aka unsigned int*}' 到 'size_t {aka unsigned int}' 的无效转换 [-fpermissive] libdeflate_deflate_compress(压缩器,in,insize,out,outsize); libdeflate.h:65:1: 注意:初始化 'size_t libdeflate_deflate_compress(libdeflate_compressor*, const void*, size_t, void*, size_t)' 的参数 5 libdeflate_deflate_compress(结构 libdeflate_compressor *compressor, make: *** [bin] 错误 1
也许我在这里没有做正确的事情。任何帮助将不胜感激 !
