Description

The list of methods to do ByteBuffer Size are organized into topic(s).

Method

BooleanneedsThumbnail(BufferedImage image, int newSize)
Check if an image should is large enough to warrant creation of a thumbnail. 
int width = image.getWidth();
int height = image.getHeight();
return newSize < width && newSize < height;
BufferedImagenewArgbBufferedImage(int width, int height)
Creates a new ARGB BufferedImage of the given width and height. 
return new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
booleanoverlapsPoints(BufferedImage inImage, int inX, int inY, int inWidth, int inHeight, Color inTextColour)
Tests whether there are any dark pixels in the image within the specified x,y rectangle 
final int BRIGHTNESS_LIMIT = 80;
final int textRGB = inTextColour.getRGB();
final int textLow = textRGB & 255;
final int textMid = (textRGB >> 8) & 255;
final int textHigh = (textRGB >> 16) & 255;
try {
    for (int x = 0; x < inWidth; x++) {
        for (int y = 0; y < inHeight; y++) {
...
ByteBufferpack(List buffers, int elements, int size)
Utility method to pack bytes into a byte buffer from a list of ByteBuffers 
ByteBuffer result = ByteBuffer.allocate(2 + size);
result.putShort((short) elements);
for (ByteBuffer bb : buffers) {
    result.putShort((short) bb.remaining());
    result.put(bb.duplicate());
return (ByteBuffer) result.flip();
BufferedImagerescaleImage(BufferedImage img, int targetWidth, int targetHeight, Object hint)
Convenience method that returns a scaled instance of the provided BufferedImage . 
if (img == null)
    throw new NullPointerException("Invalid (null) image specified");
BufferedImage tmp = new BufferedImage(targetWidth, targetHeight, BufferedImage.TYPE_INT_RGB);
Graphics2D g2 = tmp.createGraphics();
if (hint != null)
    g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, hint);
g2.drawImage(img, 0, 0, targetWidth, targetHeight, null);
g2.dispose();
...
ByteBufferrightSize(ByteBuffer in)
right Size 
if (wrapsFullArray(in)) {
    return in;
return ByteBuffer.wrap(byteBufferToByteArray(in));
booleansameSize(BufferedImage im1, BufferedImage im2)
Return true if image has the same size 
return (im1.getWidth() == im2.getWidth()) && (im1.getHeight() == im2.getHeight());
voidscanForDuplicates(BufferedImage leftImage, BufferedImage[] images, int i, int[] order, int width, int height)
scan For Duplicates 
for (int j = i + 1; j < images.length; j++) {
    BufferedImage right = images[j];
    if (right != null) {
        if (isDataEqual(leftImage, right, width, height)) {
            order[j] = i;
intsizeOfBytes(ByteBuffer bytes)
size Of Bytes 
return 2 + bytes.remaining();
intsizeOfBytesMap(Map m)
size Of Bytes Map 
int size = 2;
for (Map.Entry<String, ByteBuffer> entry : m.entrySet()) {
    size += sizeOfString(entry.getKey());
    size += sizeOfBytes(entry.getValue());
return size;
