因此,不是在用Wasm绘制的画布中加载图像,而是在代码中对图像进行编码。这类似于使用base64图像,但在编译后的wasm代码中,而不是base64中,我们可以将其加载到新选项卡中,然后将其保存为图像。 也许可以做一些事情,比如逐个像素地绘制。 浏览13提问于2018-12-21得票数 1 回答已采纳 1回答 浮点指令在x86分解PolyBen...

the api, you could also build it in a different way with only base64 data of course. for the file input we actually don’t need any other conversion since we can directly upload this file element with a standard post to our api, so open your app/home/home.page.ts and change it to...
