I have to say I am a beginner using this sort of tools.
I have this particular TIFF image that won't convert. The simple command
Code: Select all
convert.exe "test.tif" "out.jpg"
convert.exe: Photometric tag value assumed incorrect, assuming data is YCbCr instead of RGB. `TIFFReadDirectory' @ tiff.c/TIFFWarnings/526.
convert.exe: CompressNotSupported `c:\test\_imgMagick\MTS-1623\test.tif' @ tiff.c/ReadTIFFImage/810.
Using identify, I get things like:
identify: A99912q.tif: wrong data type 4 for "JpegProc"; tag ignored. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/704.
identify: Photometric tag value assumed incorrect, assuming data is YCbCr instead of RGB. `TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/704.
identify: Subsampling tag is not set, yet subsampling inside JPEG data [1,1] does not match default values [2,2]; assuming subsampling inside JPEG data is correct. `OJPEGSubsamplingCorrect' @ warning/tiff.c/TIFFWarnings/704.
identify: Depreciated and troublesome old-style JPEG compression mode, please convert to new-style JPEG compression and notify vendor of writing software. `OJPEGSetupDecode' @ warning/tiff.c/TIFFWarnings/704.
Adobe PS can't open this image, Windows Picture Viewer can't open it either. IrfanView does open it and can also save it as JPEG.
My question is - Is the "CompressNotSupported" message the main reason for failure? What I am trying to determine is if ImageMagick could do something in cases like this or not.
Not sure if the above is enough but I can't share the image just yet.
Thanks a lot
