The most convenient method to read an image from a source (File
s, InputStream
s, URL
s) is:
BufferedImage myImage = ImageIO.read( source );
But then, how to convert myImage
to a BufferedImage.TYPE_USHORT_565_RGB
format?
You can use BufferImage's getScaledInstance() to scale BufferedImage in java. final int SCALE = 2; Image img = new ImageIcon("MyFile. png").
List, the difference between Image and BufferedImage is the same as the difference between List and LinkedList. Image is a generic concept and BufferedImage is the concrete implementation of the generic concept; kind of like BMW is a make of a Car. Show activity on this post. Image is an abstract class.
This article shows how to convert a BufferedImage to a byte array or byte[] . BufferedImage bi = ImageIO. read(new File("c:\\image\\mypic. jpg")); ByteArrayOutputStream baos = new ByteArrayOutputStream(); ImageIO.
Java For Testers Java BufferedImage class is a subclass of Image class. It is used to handle and manipulate the image data. A BufferedImage is made of ColorModel of image data. All BufferedImage objects have an upper left corner coordinate of (0, 0).
You can create a new BufferedImage of the required type and then draw the original image on it, something like:
BufferedImage bufImg = ImageIO.read( imageURL ); BufferedImage convertedImg = new BufferedImage(bufImg.getWidth(), bufImg.getHeight(), BufferedImage.TYPE_USHORT_565_RGB); convertedImg.getGraphics().drawImage(bufImg, 0, 0, null);
