We are sorry to hear that you have this issue. Thank you for providing the sample file. We can confirm that GroupDocs.Viewer cannot open it - an exception “Aspose.Imaging.Exceptions.ImageFormats.TiffImageException: Cannot decode strip 0. Details: Cannot perform 2d decoding. Missing changes from previous row.” is thrown. Development team now is investigating this file, we will notify you in this forum thread when some news will arise.
Sorry for the inconvenience.
Our development team has investigated the “FZ1015FIF.tiff” TIFF file, which you have provided. The sample image CCITT T4.tiff is actually damaged, and was probably generated by some software which was interrupted during the image creation process. The software component inside the GroupDocs.Viewer, which handles the images, contains an ability to perform some data recovery. However, this particular sample TIFF file is damaged beyond repair and therefore may not recover any meaningful information.
