参考地址1:前端imageBuffer设置图片src(后端到前端直传buffer) 参考地址2:axios根据流生成图片 本质为buffer转base64
从vulkan pipeline中,我们可以看出,image主要是作为shader resource的sampled image(即传统意义上的texture),storage image,以及frame buffer中的input attachment, color attachment和depth/stencil attachment。然而相比于buffer简单的几个操作,由于image的一些特性,导致各个不同的实现之间对于image采用不同的存储策略,例如tile...
