Method Detail

makeImageTranslucent

public BufferedImage makeImageTranslucent(BufferedImage image,
                                 float translucency)

Description copied from class: ImageProcessor

Makes an image translucent. The parameter translucency has to be in the range 0.0 - 1.0

Specified by:

makeImageTranslucent in class ImageProcessor

makeColorTransparent

public BufferedImage makeColorTransparent(BufferedImage image,
                                 Color color)

Description copied from class: ImageProcessor

Makes a Color of an image transparent

Specified by:

makeColorTransparent in class ImageProcessor

flip

public BufferedImage flip(BufferedImage image,
                 int direction)

Description copied from class: ImageProcessor

Flips an image

Specified by:

flip in class ImageProcessor

direction - 0 means horizontal 1 means vertical

rotate

public BufferedImage rotate(BufferedImage image,
                   int angle)

Description copied from class: ImageProcessor

Rotates an image by an angle defined in degrees. If the angle is negative, the image will be rotated counter-clockwise. Otherwise, it will be rotated clockwise.

Specified by:

rotate in class ImageProcessor

resize

public BufferedImage resize(BufferedImage image,
                   int newWidth,
                   int newHeight)

Description copied from class: ImageProcessor

Resizes an image

Specified by:

resize in class ImageProcessor

resizeProportional

public BufferedImage resizeProportional(BufferedImage image,
                               int newWidth,
                               int newHeight)

Description copied from class: ImageProcessor

Resizes an image proportionally. The proportion is determined by the newWidth if it is not 0, irrespective of the newHeight. If the newWidth is 0, the proportion is determined by the newHeight if it is not 0. If both newWidth and newHeight are 0, no resize takes place.

Specified by:

resizeProportional in class ImageProcessor

resizeRelative

public BufferedImage resizeRelative(BufferedImage image,
                           float resizeFactorWidth,
                           float resizeFactorHeight)

Description copied from class: ImageProcessor

Resizes an image relatively to the original size. Resize factors take the value in the range [0.0 .. 1.0]

Specified by:

resizeRelative in class ImageProcessor

resizeRelativeProportional

public BufferedImage resizeRelativeProportional(BufferedImage image,
                                       float resizeFactor)

Description copied from class: ImageProcessor

Resizes an image proportionally and relative to the original size. Resize factor takes the value in the range [0.0 .. 1.0]

Specified by:

resizeRelativeProportional in class ImageProcessor
