ImageConverterG2D2Bitmap()

Method Summary

Image	convert(Image src, java.util.Map hints) Converts an image into a different representation. The new image returned shall preserve the original ImageInfo instance. Consumers can get the effective MIME type (if any) from the associated ImageFlavor.
ImageFlavor	getSourceFlavor() Returns the flavor that this converter expects.
ImageFlavor	getTargetFlavor() Returns the flavor that this converter converts images into.
protected java.awt.image.BufferedImage	paintToBufferedImage(ImageGraphics2D g2dImage, int bitsPerPixel, boolean withAlpha, int resolution) Paints a Graphics2D image on a BufferedImage and returns this bitmap.
protected void	setRenderingHintsForBufferedImage(java.awt.Graphics2D g2d) Sets rendering hints on the Graphics2D created for painting to a BufferedImage.

Method Detail

convert

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

Converts an image into a different representation.

The new image returned shall preserve the original ImageInfo instance. 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)

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
