cr2 to gif giving different Geometry metadata

Post by ankurvas » 2019-08-02T03:54:48-07:00

Hi I am using the following commandline to convert a cr2 to giff.
(Platform windows)
convert.exe C:\temp_sessions\2323086510740707015\1.cr2[0] -limit memory 8192 -limit map 16384 -limit area 32768 -quality 80 -filter Lanczos gif:C:\11808459911.gif

Problem:-
ImageMagick 6.9.2-6 Q8 x64 gives a giff with Geometry: 4176x3062+0+0
while ImageMagick 7.0.8.58 gives a giff with Geometry: 4072x3045+0+0

Why is so?
Adding the zip containing the input cr2 and both the outputs.

I suppose the different versions of IM are using different delegates. Add "-verbose" to see.

Camera sensors are larger than the nominal size in pixels. Exiftool tells us your camera (Canon Powershot SX50 HS) is nominally 4000x3000, but that is a crop from a 4176x3062 sensor.

"identify" tells you what is happening:

Code: Select all

newer_imagemagick.gif GIF 4072x3045 4176x3062+96+17 8-bit sRGB 256c 8.12436MiB 0.000u 0:00.000
From a quick scan of the exiftool metadata, I don't know where those numbers came from.

Using the identify tool with the imagemagick only but Yeah I observed in the exif tool both are returning the same metadata only.

Infact I right click and check details in windows, there as well it is showing 4072x3045.

With IM v6.9.2-6, dcraw is extracting all the pixels from the sensor, as it does by default.

With IM v7.0.8.58, it is using a built-in delegate. "magick -version" with probably show libraw. I don't know what that delegate does, but it is clearly cropping the full sensor.

Hi @snibgo
Why 7.0.8.58 is not using the dcraw? Any idea, where should I be looking.

What does "magick -version" say? Mine says:

Code: Select all

Version: ImageMagick 7.0.7-28 Q16 x64 2018-03-25 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2015 ImageMagick Studio LLC
License: http://www.imagemagick.org/script/license.php
Visual C++: 180040629
Features: Cipher DPC HDRI Modules OpenMP
Delegates (built-in): bzlib cairo flif freetype gslib heic jng jp2 jpeg lcms lqr
 openexr pangocairo png ps raw rsvg tiff webp xml zlib
So "raw" is a built-in delegate. It uses that instead of an external delegate such as dcraw.
