The JPEG Images that ImageIO generated view correctly on windows file explorer, as well as safari webbrowser, but in FireFox, the resampled images are clipped.
How do I use ImageIO without corrupting the resamples?
The code should resize image keeping aspect ratio, as well as do jpeg compression, the convert it to a byte [] array, which could be written to a socket.
some of my code. in this snippet, I tried adding Jui library, but still the same issue.
public static BufferedImage imageistream;
public void Resample(String child,double width,double height) throws Exception, InvalidFileStructureException, InvalidImageIndexException, UnsupportedTypeException, MissingParameterException, WrongParameterException
{
String imagePath = "";
if(this.is_mac_unix == true)
{
imagePath = this.path+"/"+child;
}
else
{
imagePath = this.path+"\\"+child;
}
PixelImage bmp = null;
try {
bmp = ToolkitLoader.loadViaToolkitOrCodecs(imagePath, true, null);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Resample resample = new Resample();
resample.setInputImage(bmp);
double fixedRatio = width/height;
if(((double)bmp.getWidth()/bmp.getHeight()) >= fixedRatio)
{
resample.setSize((int)width,(int)(bmp.getHeight()/(bmp.getWidth()/width)));
}
else
{
resample.setSize((int)width,(int)(bmp.getWidth()/(bmp.getHeight()/height)));
}
resample.setFilter(Resample.FILTER_TYPE_LANCZOS3);
resample.process();
PixelImage scaledImage = resample.getOutputImage();
Processor.imageistream = ImageCreator.convertToAwtBufferedImage(scaledImage);
bmp = null;
Runtime rt = Runtime.getRuntime();
rt.gc();
}
...
ByteArrayOutputStream baos = new ByteArrayOutputStream();
try {
ImageIO.write(Processor.imageistream, "jpg", baos);
// ImageIO.write(Processor.imageistream, "png", baos); Works!
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
byte bytes[] = baos.toByteArray();
ByteArrayInputStream is = new ByteArrayInputStream(bytes);
OutputStream os = (OutputStream)obj[1];
OutputStreamWriter writer = (OutputStreamWriter)obj[0];
byte[] buf= new byte[4096];
int c;
try {
while (true) {
c= is.read(buf);
if (c<= 0) break;
os.write(buf, 0, c);
}
writer.close();
os.close();
is.close();
