Hi All,

There are some warning messages which I have faced when tried to call TIFFOpen function:

TIFFReadDirectory: Warning, XXX.TIF: unknown field with tag 512 <0X200> encountered

TIFFReadDirectory: Warning, XXX.TIF: unknown field with tag 513 <0X201> encountered

TIFFReadDirectory: Warning, XXX.TIF: unknown field with tag 514 <0X202> encountered

TIFFReadDirectory: Warning, XXX.TIF: unknown field with tag 515 <0X203> encountered

TIFFReadDirectory: Warning, XXX.TIF: unknown field with tag 519 <0X207> encountered

TIFFReadDirectory: Warning, XXX.TIF: unknown field with tag 520 <0X208> encountered

TIFFReadDirectory: Warning, XXX.TIF: unknown field with tag 521 <0X209> encountered

I have found out that all this tags are belong to Old Jpeg format. So how
can I read the value from this tags?
Thanks in advanced.

Regards,
Steven
