getName
Description copied from class:PDColorSpace
Returns the name of the color space.- Specified by:
getName
in classPDColorSpace
- Returns:
- the name of the color space
-
getNumberOfComponents
public int getNumberOfComponents()Description copied from class:PDColorSpace
Returns the number of components in this color space- Specified by:
getNumberOfComponents
in classPDColorSpace
- Returns:
- the number of components in this color space
-
getDefaultDecode
public float[] getDefaultDecode(int bitsPerComponent) Description copied from class:PDColorSpace
Returns the default decode array for this color space.- Specified by:
getDefaultDecode
in classPDColorSpace
- Parameters:
bitsPerComponent
- the number of bits per component.- Returns:
- the default decode array
-
getInitialColor
Description copied from class:PDColorSpace
Returns the initial color value for this color space.- Specified by:
getInitialColor
in classPDColorSpace
- Returns:
- the initial color value for this color space
-
toRGB
Description copied from class:PDColorSpace
Returns the RGB equivalent of the given color value.- Specified by:
toRGB
in classPDColorSpace
- Parameters:
value
- a color value with component values between 0 and 1- Returns:
- an array of R,G,B value between 0 and 255
- Throws:
IOException
- if the color conversion fails
-
toRawImage
Description copied from class:PDColorSpace
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 toPDColorSpace.toRGBImage(WritableRaster)
if this returns null.- Specified by:
toRawImage
in classPDColorSpace
- Parameters:
raster
- the source raster- Returns:
- an buffered image in this colorspace. Or null if it is not possible to extract that image with the original colorspace without conversion.
- Throws:
IOException
-
toRGBImage
Description copied from class:PDColorSpace
Returns the (A)RGB equivalent of the given raster.- Specified by:
toRGBImage
in classPDColorSpace
- Parameters:
raster
- the source raster- Returns:
- an (A)RGB buffered image
- Throws:
IOException
- if the color conversion fails
-
toRGBImageAWT
Description copied from class:PDColorSpace
Returns the (A)RGB equivalent of the given raster, using the given AWT color space to perform the conversion.- Overrides:
toRGBImageAWT
in classPDColorSpace
- Parameters:
raster
- the source rastercolorSpace
- the AWT- Returns:
- an (A)RGB buffered image
