any plan for implementing images

[chollan]

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.

`var LedMatrix = require("easybotics-rpi-rgb-led-matrix");
var fs = require('fs');
var path = require('path');
const Jimp = require("jimp");
const bufferImage = require("buffer-image");
//init a 16 rows by 16 cols led matrix
//default hardware mapping is 'regular', could be 'adafruit-hat-pwm' ect
var matrix = new LedMatrix(64, 64,2,1,'regular');
let imgpath = path.join(__dirname, 'vms.bmp');
console.log(imgpath);
//let imgf = fs.readFileSync(imgpath);
//let fimgb = Buffer.from(imgf,'binary');
Jimp.read(imgpath, function (err, image) {
if (err) {
console.log(err);
} else {
//console.log(image);
//const fimgb = image.getBuffer();
//const fimgb = Buffer.from(image,'binary');
image.getBuffer(Jimp.MIME_BMP, (err, buffer) => {
console.log(buffer);
//console.log(fimgb);
while(1)
{
//matrix.drawCircle(15,35,10,0,255,255);
matrix.brightness(95);
//matrix.fill(0, 255, 0);
matrix.setImageBuffer(buffer,64,64);
matrix.update();
}
});

}

})
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.
