[iText-questions] TIFF problem

[Trevor Linton]

Hi,

 

I've been developing with iText and i've noticed some problems with iText, a specific TIF file (found at http://wendy.verite.com/~trevor/logo.tif) was producing the following error when I tried to use: document.add(Image.getInstance("logo.tif"));

 

Exception in thread "main" ExceptionConverter: ExceptionConverter: java.lang.ArrayIndexOutOfBoundsException: 7539
        at com.lowagie.text.pdf.codec.TIFFLZWDecoder.writeString(TIFFLZWDecoder.java:176)

        at Test.main(Test.java:18)

 

I was able to fix the error in what I think was a hack rather than a fix (but the image rendered, so all is well that ends well right?) I changed line com/lowagie/text/pdf/codec/TIFFLZWDecoder (176) from:

 

uncompData[dstIndex++] = string[i];

 

to:

 

if(uncompData.length > dstIndex)

    uncompData[dstIndex++] = string[i];
