Method Detail

convert

public Image convert(Image src,
                     java.util.Map hints)

Converts an image into a different representation.

Consumers can get the effective MIME type (if any) from the associated ImageFlavor.

Parameters:

src - the source image

hints - the conversion hints

Returns:

the converted image

paintToBufferedImage

protected java.awt.image.BufferedImage paintToBufferedImage(ImageGraphics2D g2dImage,
                                                            int bitsPerPixel,
                                                            boolean withAlpha,
                                                            int resolution,
                                                            boolean cmyk)

Paints a Graphics2D image on a BufferedImage and returns this bitmap.

Parameters:

g2dImage - the Graphics2D image

bitsPerPixel - the desired number of bits per pixel (supported: 1, 8, 24)

withAlpha - true if the generated image should have an alpha channel

resolution - the requested bitmap resolution

Returns:

the newly created BufferedImage

setRenderingHintsForBufferedImage

protected void setRenderingHintsForBufferedImage(java.awt.Graphics2D g2d)

Sets rendering hints on the Graphics2D created for painting to a BufferedImage. Subclasses can modify the settings to customize the behaviour.

Parameters:

g2d - the Graphics2D instance

getSourceFlavor

public ImageFlavor getSourceFlavor()

Returns the flavor that this converter expects.

Returns:

the source flavor

getTargetFlavor

public ImageFlavor getTargetFlavor()

Returns the flavor that this converter converts images into.

Returns:

the target flavor
