Method

BufferedImagesetBackgroud(BufferedImage image, Color backgroundColor)
set Backgroud 
Graphics2D g2d = image.createGraphics();
g2d.setPaint(backgroundColor);
g2d.fillRect(0, 0, image.getWidth(), image.getHeight());
g2d.dispose();
return image;
voidsetBGRPixels(byte[] bgrPixels, BufferedImage img, int x, int y, int w, int h)
converts and copies byte packed BGR or ABGR into the img buffer, the img type may vary (e.g. 
int imageType = img.getType();
WritableRaster raster = img.getRaster();
if (imageType == BufferedImage.TYPE_3BYTE_BGR || imageType == BufferedImage.TYPE_4BYTE_ABGR
        || imageType == BufferedImage.TYPE_4BYTE_ABGR_PRE || imageType == BufferedImage.TYPE_BYTE_GRAY) {
    raster.setDataElements(x, y, w, h, bgrPixels);
} else {
    int[] pixels;
    if (imageType == BufferedImage.TYPE_INT_BGR) {
...
BufferedImagesetBrightnessFactor(BufferedImage img, float multiple, BufferedImage dest)
set Brightness Factor 
float[] brightKernel = { multiple };
BufferedImageOp bright = new ConvolveOp(new Kernel(1, 1, brightKernel));
return bright.filter(img, dest);
voidsetColor(BufferedImage image, int x, int y, int[] color, String colorModel)
set Color 
if (x < 0 || x >= image.getWidth() || y < 0 || y >= image.getHeight()) {
    return;
WritableRaster raster = image.getRaster();
switch (colorModel) {
case "CMY":
case "CMYK":
    float[] rgb = cmykToRgb(1F * color[0] / 255, 1F * color[1] / 255, 1F * color[2] / 255);
...
voidsetCompressionType(ImageWriteParam param, BufferedImage image)
Sets the ImageIO parameter compression type based on the given image. 
if (image.getType() == BufferedImage.TYPE_BYTE_BINARY && image.getColorModel().getPixelSize() == 1) {
    param.setCompressionType("CCITT T.6");
} else {
    param.setCompressionType("LZW");
voidsetImageIntPixels(BufferedImage image, boolean allowDeoptimizingDirectRead, IntBuffer pixels)
set Image Int Pixels 
setImageIntPixels(image, 0, 0, image.getWidth(null), image.getHeight(null), allowDeoptimizingDirectRead,
        pixels);
voidsetLockImage(BufferedImage image)
Sets a small lock image to use when creating cycle buttons. 
lockImage = image;
voidsetLuminance(BufferedImage image, int x, int y, float value)
set Luminance 
image.setRGB(x, y, new Color(value, value, value).getRGB());
voidsetPixel(BufferedImage img, int x, int y, int c)
set Pixel 
img.setRGB(x, y, c);
voidsetPoint(BufferedImage image, int x, int y, int factor, Color color)
set Point 
for (int i = 0; i < factor; ++i) {
    for (int j = 0; j < factor; ++j) {
        image.setRGB(x * factor + i, y * factor + j, color.getRGB());
