Re: Exif bug when reading TIFFs?

Hum... ok, I see. Well, it should be possible, since the structure is basically the same. It might not be easy, given the current ImageMagick architecture (I don't know, quite frankly, just speculating...). For example, given a bunch of images used to form a final image which EXIF do you choose to u...

Re: Exif bug when reading TIFFs?

Just tested the package ImageMagick-6.7.2-7-Q16-windows-x64-static and I get the following error: convert.exe: Incompatible type for "FileSource"; tag ignored. `TIFFFetchNormalTag' @ warning/tiff.c/TIFFWarnings/715. convert.exe: incorrect count for field "ImageUniqueID" (34, expecting 33); tag trimm...

Re: Exif bug when reading TIFFs?

Thanks! And in Linux? Or will ImageMagick support HDR in windows also? Sometimes I need HDR...

Should I just use the latest TIFF release and recompile in Linux, both the libtiff and ImageMagick?

PS: when I say Linux, I also say Cygwin... posix environments.

Re: Exif bug when reading TIFFs?

Ok... this gets weirder and weirder... From wikipedia: The primary libtiff website is considered hijacked. While it now contains a mirror of the real site for current development, the libtiff.org site has not been updated since version 3.6.1. Because of this, much of the information contained therei...

Re: Exif bug when reading TIFFs?

In a Ubuntu 10.04 LTS the system libtiff segfaults when "-define tiff:exif=true" is used...

I can see the system libtiff is libtiff.so.4.3.2 but when I go to http://www.libtiff.org/ I see 3.6.1 listed as the latest version.

What's the recommended libtiff for ImageMagick?

BTW, why isn't there an HDRI-enabled Q16 windows version? Since I need that, I have to compile my own version...

Re: Exif bug when reading TIFFs?

I actually compiled imagemagick under cygwin, so this is perhaps not your fault...

I'll try to install a newer version of libtiff... or just use imagemagick under Linux, which is how it should be used anyway ;)

Re: Exif bug when reading TIFFs?

huh... over here:

Code: Select all

/usr/local/apps/ImageMagick/installed/bin/identify.exe -define tiff:exif=true -verbose small-landscape.tif
Produces no results at all... weird. Without the define it produces the results I wrote before.

ImageMagick-6.7.2-6 used here...

Seems like libtiff is broken :P

Re: Exif bug when reading TIFFs?

Perhaps you could make it a ./configure script option, when compiling ImageMagick?

Also, running identify outputs no EXIF, although the information is there, at least for Windows (File->Properties) and PhotoShop... identify -verbose small-landscape.tif Output: Image: small-landscape.tif Format: TIFF (Tagged Image File Format) Class: DirectClass Geometry: 300x200+0+0 Resolution: 30...

Re: Exif bug when reading TIFFs?

Not doing any processing results in two frames, both without exif. Try yourself:

Code: Select all

convert small-landscape.tif jpg:small-landscape2.jpg

Exif bug when reading TIFFs?

Hi! While doing my "isolated pixel cleaning" (a solved problem now, many thanks!) I noticed that the EXIF information contained in the TIFF was lost in transit... So that you can easily check out what seems like a bug I generated a small version of the TIFF using the same program (SilkyPix) and whic...

Re: Finding isolated pixels.

I found this worked great:

Code: Select all

convert Lenna-128-isolated.tif \( +clone -morphology HMT Peaks:1.5 \) +swap -compose subtract -composite Lenna-128-subtract.tif

Re: Finding isolated pixels.

Anthony, the Morphology method seems to work rather well, thanks! I'll test it on some real images with real hot pixels and report the results. The problem is that hot pixels are not as "hot" as in my example images, and the "fx" method seems more sensitive. Then again, only practice will tell :) I ...
