> {noformat}
> ArrayIndexOutOfBoundsException: Index 3 out of bounds for length 3
> org.apache.pdfbox.pdmodel.graphics.color.PDSeparation.tintTransform(PDSeparation.java:222)
> org.apache.pdfbox.pdmodel.graphics.color.PDSeparation.toRGBImage(PDSeparation.java:169)
> org.apache.pdfbox.pdmodel.graphics.color.PDIndexed.initRgbColorTable(PDIndexed.java:152)
> org.apache.pdfbox.pdmodel.graphics.color.PDIndexed.<init>(PDIndexed.java:93)
> org.apache.pdfbox.pdmodel.graphics.color.PDColorSpace.create(PDColorSpace.java:188)
> {noformat}
> The cause is that the range array is too short (7 elements for CMYK).
> I'll catch this in the constructor and return an exception. If there's a complaint then we could change the tintTransform() method so that it takes the minimum of alt.length and result.length.
