I try to set buffer but it return error: node: ../src/ledmatrix.cc:530: static void LedMatrix::SetImageBuffer(const Nan::FunctionCallbackInfo<v8::Value>&): Assertion
(int)bufl == widthheight3' failed.
Aborted
This is more of a feature request, or for someone to point me in the right direction: is there any plan to support images using the setImageBuffer method or any similar? i see images are supported within easybotics/node-red-contrib-easybotics-led-matrix, but i see no documentation about images for nodejs.
