Class StandardColorSpaceHelper

java.lang.Object
org.apache.pdfbox.preflight.graphic.StandardColorSpaceHelper
All Implemented Interfaces:
ColorSpaceHelper
Direct Known Subclasses:
DeviceColorSpaceHelper, NoPatternColorSpaceHelper
public class StandardColorSpaceHelper extends Object implements ColorSpaceHelper
This class doesn't define restrictions on ColorSpace. It checks only the consistency of the Color space with the DestOutputIntent.

  • Field Details

    • context

      protected PreflightContext context
      The context which contains useful information to process the validation.

    • iccpw

      protected ICCProfileWrapper iccpw
      The ICCProfile contained in the DestOutputIntent

    • pdcs

      protected PDColorSpace pdcs
      High level object which represents the colors space to check.

  • Constructor Details

  • Method Details

    • validate

      public final void validate() throws ValidationException
      Description copied from interface: ColorSpaceHelper
      Process the ColorSpace validation.
      Specified by:
      validate in interface ColorSpaceHelper
      Throws:
      ValidationException

    • processAllColorSpace

      protected final void processAllColorSpace(PDColorSpace colorSpace)
      Method called by the validate method. According to the ColorSpace, a specific ColorSpace method is called.
      Parameters:
      colorSpace - the color space object to check.

    • processRGBColorSpace

      protected void processRGBColorSpace(PDColorSpace colorSpace)
      Method called by the processAllColorSpace if the ColorSpace to check is DeviceRGB.

    • processCYMKColorSpace

      protected void processCYMKColorSpace(PDColorSpace colorSpace)
      Method called by the processAllColorSpace if the ColorSpace to check is DeviceCYMK.

    • processPatternColorSpace

      protected void processPatternColorSpace(PDColorSpace colorSpace)
      Method called by the processAllColorSpace if the ColorSpace to check is a Pattern.
      Parameters:
      colorSpace -

    • processGrayColorSpace

      protected void processGrayColorSpace(PDColorSpace colorSpace)
      Method called by the processAllColorSpace if the ColorSpace to check is DeviceGray.

    • processCalibratedColorSpace

      protected void processCalibratedColorSpace(PDColorSpace colorSpace)
      Method called by the processAllColorSpace if the ColorSpace to check is a calibrated color (CalGray, CalRGB, Lab).
      Parameters:
      colorSpace -

    • processICCBasedColorSpace

      protected void processICCBasedColorSpace(PDColorSpace colorSpace)
      Method called by the processAllColorSpace if the ColorSpace to check is a ICCBased color space. Because this kind of ColorSpace can have alternate color space, the processAllColorSpace is called to check this alternate color space. (Pattern is forbidden as Alternate Color Space)
      Parameters:
      colorSpace - the color space object to check.

    • processDeviceNColorSpace

      protected void processDeviceNColorSpace(PDColorSpace colorSpace)
      Method called by the processAllColorSpace if the ColorSpace to check is DeviceN. Because this kind of ColorSpace can have alternate color space, the processAllColorSpace is called to check this alternate color space. (There are no restrictions on the Alternate Color space)
      Parameters:
      colorSpace - the color space object to check.

    • processIndexedColorSpace

      protected void processIndexedColorSpace(PDColorSpace colorSpace)
      Method called by the processAllColorSpace if the ColorSpace to check is Indexed. Because this kind of ColorSpace can have a Base color space, the processAllColorSpace is called to check this base color space. (Indexed and Pattern can't be a Base color space)
      Parameters:
      colorSpace - the color space object to check.

    • processSeparationColorSpace

      protected void processSeparationColorSpace(PDColorSpace colorSpace)
      Method called by the processAllColorSpace if the ColorSpace to check is Separation. Because this kind of ColorSpace can have an alternate color space, the processAllColorSpace is called to check this alternate color space. (Indexed, Separation, DeviceN and Pattern can't be a Base color space)
      Parameters:
      colorSpace - the color space object to check.

    • processDefaultColorSpace

      protected boolean processDefaultColorSpace(PDColorSpace colorSpace)
      Look up in the closest PDResources objects if there are a default ColorSpace. If there are, check that is a authorized ColorSpace.
      Parameters:
      colorSpace -
      Returns:
      true if the default colorspace is a right one, false otherwise.

    • validateICCProfileVersion

      private boolean validateICCProfileVersion(ICC_Profile iccp)

    • validateICCProfileNEntry

      private boolean validateICCProfileNEntry(COSStream stream, ICC_Profile iccp)

    • validateICCProfileAlternateEntry

      private void validateICCProfileAlternateEntry(PDICCBased iccBased, PDColorSpace alternateColorSpace)
