             Summary: ArrayIndexOutOfBoundsException in PDSeparation.tintTransform()
                 Key: PDFBOX-5352
                 URL: https://issues.apache.org/jira/browse/PDFBOX-5352
             Project: PDFBox
          Issue Type: Bug
          Components: Rendering
    Affects Versions: 2.0.25
            Reporter: Tilman Hausherr
            Assignee: Tilman Hausherr
             Fix For: 2.0.26, 3.0.0 PDFBox


I get this with the attached file from the linked poppler issue
{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.
