TIFF: negative image positions unsupported

[starquad]

Hi,

I am "a little bit" stuck I am getting the error "TIFF: negative image positions unsupported" (see below) when running convert.exe (see below) on a TIF-image (see info below) in order to rotate that image be 90 degrees.

There is no issue when converting jpg-files, so I don't see why the same would not work for tif-files? Also, I can't make any sense of "negative image positions". Is this a bug or am I missing something? Any alternatives to rotating an image by +90 or -90 degrees?

Any help would be greatly appreciated. Thank you!

Here is the full error message:

Code: Select all

convert.exe -rotate 90 page001.tif out.tif

Tif can't store negative offsets, so "+repage" is the usual cure for this.

However, I notice that your command is in the wrong order. It should be:

Code: Select all

convert.exe page001.tif -rotate 90 out.tif

And "-rotate 90" shouldn't create a negative offset. I happen to have 6.8.8-9 x86, exactly the same as you, and neither your command nor the correct version gives this problem. Nor does the current version of IM.

Hi,

fantastic! Thanks a lot! +repage is indeed the cure.

BTW, the "-rotate 90" produces the same result whether it is before or after the source file. In fact, I used your version originally, but when I became desperate, I moved this around

Anyway, thank you so much for the perfectly on target hint!
