java.lang.ArrayIndexOutOfBoundsException while converting PDF to TIFF
[ https://issues.apache.org/jira/browse/PDFBOX-3501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15496757#comment-15496757 ]

The javadoc of getNormalizedComponents warns about this:
{quote}
An ArrayIndexOutOfBoundsException is thrown if pixel is not large enough to hold a pixel value for this ColorModel.
{quote}
In BlendComposite:
numSrcComponents: 4
numDstComponents: 1
the dstColorModel has numComponents = 3, but dstPixel and dstComponents are both byte arrays with len 1.
dstColorModel: IndexColorModel: #pixelBits = 1 numComponents = 3 color space = java.awt.color.ICC_ColorSpace@3d8c7aca transparency = 1 transIndex = -1 has alpha = false isAlphaPre = false
srcColorModel: DirectColorModel: rmask=ff0000 gmask=ff00 bmask=ff amask=ff000000
The solution I did is temporary, but we no longer get an unchecked exception. The result b/w image is not good.
