Re: Moving large data between JS & wasm with IDL binder

Is is possible to use a typed array created on HEAP8 with XMLHttpRequest as the destination for the incoming data? Regards -Mark > On Jul 9, 2020, at 9:44, Alon Zakai wrote: > > HEAP8 is one of the global variables the emscripten JS always has. It's > always present for code in a JS

Re: Moving large data between JS & wasm with IDL binder

HEAP8 is one of the global variables the emscripten JS always has. It's always present for code in a JS library, --pre-js, or other code that is part of the main JS output (that is all optimized together). On Wed, Jul 8, 2020 at 6:39 PM キャロウ マーク wrote: > Thanks Alon. > > > On Jul 8, 2020, at

Re: Moving large data between JS & wasm with IDL binder

Embind and the WebIDL binder are separate tools. They don't have any special support for mixing between them. The WebIDL binder doesn't have direct support for copying data from JS into wasm. You can do it manually though, without the WebIDL binder, by malloc()ing some room, copying the data (all

Moving large data between JS & wasm with IDL binder

Can anyone here explain, or point me at an example, of how to move large data, e.g an image, between JS memory and wasm memory using a function defined with WebIDL binder? In embind for moving data from JS to wasm, I use an emscripten::val parameter to pass in the JS handle then
