In this code, variable “byteImageValue” is the actual image byte code.
byte[] byteResizedImageValue;
try {
ByteArrayInputStream inputStream =
new ByteArrayInputStream(byteImageValue);
ByteArrayOutputStream baos =
new ByteArrayOutputStream();
byte[] imageInByte =
null;
BufferedImage bufferedImage = ImageIO.read(inputStream);
int intResizeWidth = bufferedImage.getWidth()+25;
int intResizedHeight = bufferedImage.getHeight()+10;
BufferedImage resizedImage =
new BufferedImage(intResizeWidth, intResizedHeight, BufferedImage.TYPE_INT_ARGB);
Graphics g = resizedImage.getGraphics();
g.drawImage(bufferedImage, 0, 0, intResizeWidth, intResizedHeight,
null);
g.dispose();
ImageIO.write(resizedImage,
"PNG", baos );
baos.flush();
imageInByte = baos.toByteArray();
baos.close();
byteResizedImageValue = imageInByte;
}
catch (IOException objImageIOException) {
//
TODO Auto-generated catch block
throw
new ScriptException(generalErrorCode,
"Invalid image." + objImageIOException.getMessage());
}
