2005.08.24 04:59 "Re: TIFF Thumbnail", by Katrina Maramba
Hello, I encountered a problem on one of the thumbnails of the images I have.. While parsing the thumbnail data through the API TIFFReadRGBAStrip, it had an error in TIFFRGBAImageOK that says "Sorry, can not handle images with 0-bit samples." I checked in AsTiffTagViewer, it displayed: BitsPerSample Short 3 (count) 8,8,8 (value) But in Hex Workshop: The value pointed by the offset in tag 102 of the thumbnail IFD is indeed 0. How come the AsTiffTagViewer found the three 8's? Is there a behavior that the child (which is the thumbnail) would inherit this particular characteristic of the parent (main image)??? Please help. Thanks! Katrina
