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

validate
Description copied from interface:ColorSpaceHelper
Process the ColorSpace validation.- Specified by:
validate
in interfaceColorSpaceHelper
- Throws:
ValidationException
-
processAllColorSpace
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
Method called by the processAllColorSpace if the ColorSpace to check is DeviceRGB. -
processCYMKColorSpace
Method called by the processAllColorSpace if the ColorSpace to check is DeviceCYMK. -
processPatternColorSpace
Method called by the processAllColorSpace if the ColorSpace to check is a Pattern.- Parameters:
colorSpace
-
-
processGrayColorSpace
Method called by the processAllColorSpace if the ColorSpace to check is DeviceGray. -
processCalibratedColorSpace
Method called by the processAllColorSpace if the ColorSpace to check is a calibrated color (CalGray, CalRGB, Lab).- Parameters:
colorSpace
-
-
processICCBasedColorSpace
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
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
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
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
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.
