`colorSpace`

Fields inherited from class org.apache.fop.pdf.PDFObject
`DATE_FORMAT, log`

Constructor Summary
`PDFColor(java.awt.Color col)` Create a PDF color from a java.awt.Color object.
`PDFColor(double theRed, double theGreen, double theBlue)` Create a PDF color with double values ranging from 0 to 1
`PDFColor(double theCyan, double theMagenta, double theYellow, double theBlack)` Create a PDF color with CMYK values.
`PDFColor(int theRed, int theGreen, int theBlue)` Create a PDF color with int values ranging from 0 to 255
`PDFColor(PDFDocument pdfDoc, java.awt.Color col)` Create PDFColor for the given document and based on the java.awt.Color object In case the java.awt.Color is an instance of the ColorExt class a PDFICCStream is added to the PDFDocument that is being created

Method Summary
`double` | `black()` Get the black component.
`double` | `blue()` Get the blue component.
`int` | `blue255()` Get the blue integer component.
`protected boolean` | `contentEquals(PDFObject obj)` Check if the other PDFObject has the same content as the current object. Note: This function has a contract which is less binding than `Object.equals(Object)`. Whereas equals would require all values to be identical, this method is not required to check everything. In the case of PDFObjects, this means that the overriding function does not have to check for `PDFObject.getObjectID()`.
`protected void` | `convertCMYKtoGRAY()` Convert the color from CMYK to Gray.
`protected void` | `convertCMYKtoRGB()` Convert the color from CMYK to RGB.
`protected void` | `convertGRAYtoCMYK()` Convert the color from Gray to CMYK.
`protected void` | `convertGRAYtoRGB()` Convert the color from Gray to RGB.
`protected void` | `convertRGBtoCMYK()` Convert the color from RGB to CMYK.
`protected void` | `convertRGBtoGRAY()` Convert the color from RGB to Gray.
`double` | `cyan()` Get the cyan component.
`java.lang.String` | `getColorSpaceOut(boolean fillNotStroke)` Get the PDF output string for this color.
`java.util.List` | `getVector()` Return a vector representation of the color in the appropriate colorspace.
`double` | `green()` Get the green component.
`int` | `green255()` Get the green integer component.
`double` | `magenta()` Get the magenta component.
`double` | `red()` Get the red component.
`int` | `red255()` Get the red integer component.
`void` | `setColorSpace(int theColorSpace)` Set the color space for this color.

### contentEquals

    protected boolean contentEquals(PDFObject obj)

  Check if the other PDFObject has the same content as the current object.

  Note: This function has a contract which is less binding than `Object.equals(Object)`. Whereas equals would require all values to be identical, this method is not required to check everything. In the case of PDFObjects, this means that the overriding function does not have to check for `PDFObject.getObjectID()`.
