Description

The list of methods to do BufferedImage Encode are organized into topic(s).

Method

String encode(RenderedImage image, String formatName)
encode

try (ByteArrayOutputStream baos = new ByteArrayOutputStream();
 BufferedOutputStream bos = new BufferedOutputStream(baos);) {
 ImageIO.write(image, formatName, bos);
 bos.flush();
 return Base64.getEncoder().encodeToString(baos.toByteArray());
} catch (IOException e) {
 throw new RuntimeException(e);

void encodeAndWriteJPEGFile(File file, BufferedImage image, float quality)
encode And Write JPEG File

Iterator<ImageWriter> iter = ImageIO.getImageWritersByFormatName("jpeg");
ImageWriter writer = iter.next();
ImageWriteParam iwp = writer.getDefaultWriteParam();
iwp.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);
iwp.setCompressionQuality(quality);
FileImageOutputStream output = new FileImageOutputStream(file);
writer.setOutput(output);
IIOImage iioi = new IIOImage(image, null, null);
...

byte[] encodeBufferedImageAsJPEG(BufferedImage bi)
Stores BufferedImage as JPEG encoded bytestream

byte[] byteStream = null;
ByteArrayOutputStream baos = new ByteArrayOutputStream(1024);
ImageIO.write(bi, "jpeg", baos);
baos.flush();
byteStream = baos.toByteArray();
baos.close();
return byteStream;

String encodeImage(BufferedImage image)
encode Image

String imageString = null;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try {
 ImageIO.write(image, "png", bos);
 byte[] imageBytes = bos.toByteArray();
 imageString = DatatypeConverter.printBase64Binary(imageBytes);
 bos.close();
} catch (IOException e) {
...

String encodeImage(BufferedImage image)
create an ascii-encoded representation of the given image

ByteArrayOutputStream bos = new ByteArrayOutputStream();
ImageIO.write(image, "jpg", bos);
byte[] bytes = bos.toByteArray();
BASE64Encoder base64Encoder = new BASE64Encoder();
return base64Encoder.encode(bytes);

String encodeImageToBase64(BufferedImage image)
Encodes target image to a Base64 string

String encodedImage = "";
Base64 encoder = new Base64();
try {
 ByteArrayOutputStream baos = new ByteArrayOutputStream();
 ImageIO.write(image, "png", baos);
 baos.flush();
 byte[] encodedBytes = encoder.encode(baos.toByteArray());
 encodedImage = new String(encodedBytes);
...

byte[] encodeImageToPNGByteArray(BufferedImage image)
encode Image To PNG Byte Array

try {
 ByteArrayOutputStream bos = new ByteArrayOutputStream();
 ImageIO.write(image, "png", bos);
 return bos.toByteArray();
} catch (Exception e) {
 e.printStackTrace(System.err);
return null;
...

byte[] encodeJPEG(BufferedImage image)
Performs in-memory encoding of a BufferedImage to a byte array.

ByteArrayOutputStream resultStream = new ByteArrayOutputStream();
try {
 ImageIO.write(image, "jpeg", resultStream);
} catch (IOException e) {
 throw new Error(e);
return resultStream.toByteArray();

void encodePNG(BufferedImage image, String pathAndFileName)
encode PNG

try {
 ImageIO.write(image, "png", new File(pathAndFileName));
} catch (Exception e) {
 e.printStackTrace(System.err);

String encodeToImgElement(BufferedImage image, String formatName)
encode To Img Element

return encodedImageToImgElement(encode(image, formatName), formatName);
