The Windows version of ImageMagick is self-installing. Simply click on the appropriate version below and it will launch itself and ask you a few installation questions. Versions with Q8 in the name are 8 bits-per-pixel component (e.g. 8-bit red, 8 ...

Hello,

I have a bunch of (scan) jpegs, which have different pixel resolutions and display ratios.
for instance 730x1080, 764x1080, 2059x2912

I which to convert all of them to A4 format, aka 210x297 in whatever sufficient dpi.

Hi,

Requesting a small change in install under Windows (and Linux).

1/ FFmpeg is a very used app, not only by IM, therefore it would be nice to have a feature at ImageMagick install to ask if it should take the path to an already existing ffmpeg or rather install its own ffmpeg.

On my system, due ...

RE: http://www.imagemagick.org/script/download.php

Hello,

I want to build from source, but in the latest the source are named as ImageMagick-6.9.0-4.tar.gz
Where is the Q16 version?

Thanks

Hi,

Under Win 7, I have installed ImageMagick-6.8.9-1-Q16-x64-static.exe

Now, inside IM folder there is ffmpeg.exe

As ffmpeg is daily updated for improving (almost) in matters of bugs, hardware support (for instance enabling SSE2) and codec support, I wonder if IM can't be linked to updated ...

ImageMagick 6.8.6-7 2013-07-23 Q16

Hello,

Each time I batch process with non English characters in the file name, the montage fails

eCli Example:
montage -mode concatenate -tile 3x2 *.jpg -resize 900x +adjoin _3Cols_2Rows%02d.jpg

Output error example:
montage.exe: unable to ...

On your side, can you reproduce the issue?

If the file name contains non US chars, such as éçàù.... then it does not work.

Test case:
à.jpg
é.jpg
è.jpg
ê.jpg

identify *.jpg > dumpImgsIndentity.txt
Output
identify.exe: unable to open image `à.JPG': No such file or directory @ error/blob.c/OpenBlob/2643.
identify.exe: unable to open image ...

* works perfectly in another directory

* Note: no error is prompted on shell.
Oups, My mistake

montage.exe: unable to open image `.....': No such file or directory @ error/blob.c/OpenBlob/2643.

I look into that

Hi,

Under Win7, I have a directory of jpeg, they are lexically sorted by some date preceeding some comment about the image content, for example:
2011-07-12 12h15 My first image.jpg
2012-08-29 09h45 éèàç.jpg

Using the lexicographic order of the files, I want to make a montage of the image by group ...

OK, my prime question was badly formulated, I agree when working on the source shot.

But as soon as for instance, one applies some transformations, for example:
convert -auto-orient -crop 2752x2168+1300+600 -normalize -resize 1980x1980
What EXIF are still correct and usefull to keep, or if you ...

Normally one strips the EXIF.
But, are some usefull to keep to perform image processing?
Maybe, just these two?
%Q
identify -format '%[exif:orientation]

Are focus point & white balance, lens, aperture information, useful ??

>I understand what you are saying and that makes sense
Thanks :)

>Are you otherwise modifying the images, or are you simply reading them in and writing them back out but possibly smaller?

It should be a general behaviour, but you're right it most happens when the source is a non "raw" photo jpeg ...

Hi,

how to make -quality <%> so that it's bound to the current photo max.
This info is in
identify -verbose

I mean, take a low quality jpeg and convert -quality 96 for instance, than the output jpeg is way bigger.
It's obviously not what you want, you want the max quality regarding the ...
