public BufferedImage toRawImage(WritableRaster raster)

Implements abstract org.apache.pdfbox.pdmodel.graphics.color.PDColorSpace.toRawImage.

Doc from org.apache.pdfbox.pdmodel.graphics.color.PDColorSpace.toRawImage.

Returns the image in this colorspace or null. No conversion is performed. For special colorspaces like PDSeparation the image is returned in the gray colorspace. For undefined colorspaces like DeviceCMYK/DeviceRGB and DeviceGray null is returned. You can always fallback to toRGBImage(WritableRaster) if this returns null.

Parameters
raster:WritableRaster

the source raster

Returns:BufferedImage

an buffered image in this colorspace. Or null if it is not possible to extract that image with the original colorspace without conversion.

Returns the RGB equivalent of the given color value.

Parameters
value:float[]

a color value with component values between 0 and 1
