Code integration

// Loads the PDFix Wasm in JavaScript
PDFIX_WASM().then(function (wasm) {
  PDFIX_SDK = wasm;
  PDFIX_SDK.GetPdfix = function() {
    return wasm.wrapPointer(wasm._GetPdfix(), wasm.Pdfix);
  }
  PDFIX_SDK.GetPdfToHtml = function() {
    return wasm.wrapPointer(wasm._GetPdfToHtml(), wasm.PdfToHtml);
  }
  PDFIX_SDK.allocArray = function (typedArray) {
    var numBytes = typedArray.length * typedArray.BYTES_PER_ELEMENT;
    var ptr = wasm._malloc(numBytes);
    var heapBytes = new Uint8Array(wasm.HEAPU8.buffer, ptr, numBytes);
    heapBytes.set(new Uint8Array(typedArray.buffer));
    return [heapBytes.byteOffset, typedArray.length];
  };
  PDFIX_SDK.allocString = function(string){
    const bufSize = wasm.lengthBytesUTF32(string);
    var buffer = wasm._malloc(bufSize + 4);
    wasm.stringToUTF32(string, buffer, bufSize + 4);
    return [buffer, string.length];
  }

  // your code...

});
