When I try to convert a specific tiff file to PDF, the following exception occurs:
java.lang.RuntimeException: Scanline must begin with EOL code word.
I can open the tiff file in any image viewer, so it's valid.
Comment by Bruno: this statement is not always true: I can open the tiff file in any image viewer, so it's valid. A TIFF file can be invalid and open in an image viewer anyway because the image viewer tolerates errors. iText can also tolerate errors, as explained in the answer provided by Michaël Demey (from iText).
iText has a few fall backs when dealing with invalid or corrupt Tiff files. By default, these fallbacks aren't used, you'll need to explicitly use one of the
getinstance() methods with the
recoverFromImageError flag set to
true if you want iText to try and parse the invalid Tiff files
getInstance(byte imgb, boolean recoverFromImageError)]. If the
boolean parameter is set to
true, iText will only throw an error if it exhausted all of its options.
Another workaround could be to use the
TiffImage class, bypassing the
Image class altogether. The
TiffImage class also uses the
recoverFromImageError flag, but it also has an additional flag called
direct which might also solve your issues.
