Method Detail

getScalableImage

public static ImageWrapper getScalableImage(java.lang.String name,
                                            int width,
                                            int height)

Gets the new image data byte array for prepackaged scalable images. No antialiasing is applied to the resulting image.

Parameters:

name - The name for image to be loaded from p2j.jar.

width - The required image width.

height - The required image height.

Returns:

The byte array data for the image to be loaded or null if there is no data.

getScalableImage

public static ImageWrapper getScalableImage(java.lang.String name,
                                            java.lang.String location,
                                            int width,
                                            int height)

Gets the new image data byte array for prepackaged scalable images. No antialiasing is applied to the resulting image.

Parameters:

name - The name for image to be loaded from p2j.jar.

location - The theme specific location for image to be loaded.

width - The required image width.

height - The required image height.

Returns:

The byte array data for the image to be loaded or null if there is no data.

getScalableImage

public static ImageWrapper getScalableImage(java.lang.String name,
                                            java.lang.String location,
                                            int width,
                                            int height,
                                            boolean antialias)

Gets the new image data byte array for prepackaged scalable images.

Parameters:

name - The name for image to be loaded from p2j.jar.

location - The theme specific location for image to be loaded.

width - The required image width.

height - The required image height.

antialias - Set false to skip antialias processing the output image, true otherwise.

Returns:

The byte array data for the image to be loaded or null if there is no data.

getScalableImage

public static ImageWrapper getScalableImage(java.io.InputStream is,
                                            int width,
                                            int height,
                                            boolean antialias)

Gets the bitmap image from svg input stream. It doesn't close input stream.

Parameters:

is - The given SVG input stream

width - The required image width.

height - The required image height.

antialias - Set false to skip antialias processing the output image, true otherwise.

Returns:

The generic wrapper representing the given image or null if the image can't be created (e.g. if the bytes are not a valid image type).
