Method Detail

resize

public static byte[] resize(byte[] imageData,
                            int maxWidth,
                            int maxHeight,
                            int jpegQuality)

reorientImage

public static BufferedImage reorientImage(BufferedImage image,
                                          boolean yAxisFlipNeeded,
                                          int cwRotationNeeded)

Flipping (Mirroring) is performed BEFORE Rotating the image. Example: Flipping the image over the y Axis, and then rotating it 90 degrees CW is not the same as rotating the image 90 degrees CW and then flipping it over the y Axis.

flipImageHorizontally

public static BufferedImage flipImageHorizontally(BufferedImage image)

flipImageVertically

public static BufferedImage flipImageVertically(BufferedImage image)

rotateImage

public static BufferedImage rotateImage(BufferedImage image,
                                        int cwRotationNeeded)

getScaledDimension

public static int[] getScaledDimension(int originalWidth,
                                       int originalHeight,
                                       int boundWidth,
                                       int boundHeight)

thumbnailType

public static int thumbnailType(BufferedImage image)

getImageFormat
