i want to get the buffered image format or type of image using java,
InputStream stream = request.getResponseStream();
BufferedImage image= ImageIO.read(stream);
LOGGER.info(image);
537
BufferedImage buffer = ImageIO. read(new File(file)); to Image i.e in the format something like : Image image = ImageIO.
The formatName parameter selects the image format in which to save the BufferedImage . try { // retrieve image BufferedImage bi = getMyImage(); File outputfile = new File("saved. png"); ImageIO. write(bi, "png", outputfile); } catch (IOException e) { ... }
A BufferedImage is comprised of a ColorModel and a Raster of image data. The number and types of bands in the SampleModel of the Raster must match the number and types required by the ColorModel to represent its color and alpha components. All BufferedImage objects have an upper left corner coordinate of (0, 0).
Just use the read method of the Java ImageIO class, and you can open/read images in a variety of formats (GIF, JPG, PNG) in basically one line of Java code.
Refer the javax.imageio.ImageIO.read() code
This code originally implemented in groovy but translated into java so It may have a syntax error.
public String read(InputStream input) throws IOException {
ImageInputStream stream = ImageIO.createImageInputStream(input);
Iterator iter = ImageIO.getImageReaders(stream);
if (!iter.hasNext()) {
return null;
}
ImageReader reader = (ImageReader) iter.next();
ImageReadParam param = reader.getDefaultReadParam();
reader.setInput(stream, true, true);
BufferedImage bi;
try {
bi = reader.read(0, param);
return reader.getFormatName();
} finally {
reader.dispose();
stream.close();
}
}
