Byte array to Image: /// <summary> /// Method that uses the ImageConverter object in .Net Framework to convert a byte array, /// presumably containing a JPEG or PNG file image, into a Bitmap object, which can also be /// used as an Image object. /// </summary> /// <param name=byteArray>byte array containing JPEG or PNG file image or similar</param> /// <returns>Bitmap object if it works, else exception is thrown</returns> public static Bitmap GetImageFromByteArray(byte[] byteArray. EDIT: I just realized the question is a bit ambigious, so the answer below might not fit.If the byte array is something you have in the .NET CLR side of things, then base64 is probably the way to go, but if it's something you create or deal with in the client, my answer below is the way to go.. Converting the byte array to base64 when you have the binary byte array is ridiculously expensive. To convert a byte array to an image. Create a ByteArrayInputStream object by passing the byte array (that is to be converted) to its constructor. Read the image using the read() method of the ImageIO class (by passing the ByteArrayInputStream objects to it as a parameter) image2cpp is a simple tool to change images into byte arrays (or your array back into an image) for use with Arduino and (monochrome) displays such as OLEDs. It was originally made to work with the Adafruit OLED library. An example sketch for Arduino and this library can be found here. More info (and credits) can be found in the Github repository. This is also where you can report any issues.

Here Mudassar Ahmed Khan has explained with an example, how to display Images from JSON Array using JavaScript. This article will illustrate how to display Images in a dynamic HTML Table generated by looping through the JSON Array using JavaScript. The Images will be stored in a Folder (Directory) on the Server and will be displayed in an HTML Image element using JavaScript Create an instance of the FileStream and specify the file path along with the File Mode and the File Access.; Create an instance of the BinaryReader and specify the fileStream instance as parameter for the constructor. Read the Byte one by one from the Binary reader and assign it to the Byte Array that you want to return Convert BufferedImage to Byte Array. We create the BufferedImage by using ImageIO.read() and passing in the location of the image as an argument. Since ByteArrayOutputStream implements Closeable, we can create a ByteArrayOutputStream inside the try-catch block and the java runtime will automatically handle the closing of the stream. Next we write the BufferedImage to the ByteArrayOutputStream. private void createImageData() { int i = 0; for (int y = 0; y < IMAGE_HEIGHT; y++) { System.out.println(y: +y); int r = y * 255 / IMAGE_HEIGHT; for (int x = 0; x < IMAGE_WIDTH; x++) { System.out.println(\tx: +x); int g = x * 255 / IMAGE_WIDTH; imageData[i] = (byte) r; imageData[i + 1] = (byte) g; System.out.println(\t\tR: +(byte)r); System.out.println(\t\tG: +(byte)g); i += 3; } } }. This example reads an image as a binary file and creates an 8-bit unsigned integer array from the raw bytes. Note that this will not decode the image and read the pixels. You will need a png decoding library for that. var oReq = new XMLHttpRequest () ; oReq. open (GET, /myfile.png, true); oReq. responseType = arraybuffer; oReq. onload = function (oEvent) {var arrayBuffer = oReq. response.
