I have just installed my first 7.x version of IM (i.e. with magick.exe) as a precompiled windows binary. How do i found out whether it uses jpeg-turbo and if so, how can I use arithmetic coding? magick -list format yields JPEG* JPEG rw- Joint Photographic Experts Group JFIF format (62) I think that ...

Problem: A lot of PDF printers cut photos into horizontal stripes or even tiles. You can extract these sniplets with the help of the xpdf tools and re-combine them with Montage, preferably sending their filenames to a batch file via SendTo. However, the filenames are not sorted by name when sent. S...

As I understand, you are working under Windows, so your question is more about Windows than about ImageMagick. The easiest way to establish this functionality would be to place the batch file in the SendTo folder, see http://www.imagemagick.org/Usage/windows/#scripts . You then have to refer to the ...

This problem has been annoying me for years now. (I think, I also mentioned it on this board.) Today I found out that the instertion of a simple "-colorspace gray" does the trick, i.e. something along the lines of (Windows batch file): convert -density 300 %1 -trim -colorspace gray -compre...

Hi all, today I took the time and drew two mindmaps http://www.unfallrekonstruktion.de/imagemagick/Current.html http://www.unfallrekonstruktion.de/imagemagick/Future.html what the logical structure of a to-be CMS could look like. The single pages must definitively become shorter to keep them maintai...

The problem seems to be solved in current versions of IM. I have just installed the current version, and now even the JPEGs exported by Photoshop are recognised with the correct resolution -- both by the Windows Explorer and Microsoft Word. Up to now I still ran IM 6.8.0-1, dating from 2012: This wa...

I often rescale photos in order to embed them in a Microsoft Word document and print them. My batch code is basically convert %1 -resize 1024x1024">" -quality 80%% -units PixelsPerInch -density 170 "%~dpn1_small.jpg" This works fine with most JPEGs, i.e. photos and JPEGs exported...

I have just had another check on this subject after quite a while –- and found the issue solved in the current IM version. The batch script now works again like it did before the problem occured. No more problems with German umlauts in Montage's filename globbing.

I see no way to specify the maximum (or minimal) JPEG quality. I often do bulk conversions of JPEG photographs, reducing their size in order to embed them in a Word document. The JPEG quality of normal photographs is something like 95%, so if I specify '-quality 90%', the bulk-converted photographs ...

OK, I'll try to produce a small demo, i.e. transfer a small amount of the Usage section into WordPress or alike and see where this will lead me. And in a few weeks we may have something to discuss about. You are probably right: Theoretical discussions are of limited use, one has to try to make thing...

I think that we should restrict the editors of this website to just a few people, so junk will (hopefully) no problem. This would be a problem if running it as a wiki, as I had to found out myself in another project. But in this case, we will just restrict the access, I guess. Jürgen and I have thou...

Dear all, I've been corresponding with Anthony during the last months. In principle he told me, that he is not going to work on his Usage branch of IM's website any further. I proposed to transfer the entire Usage section into a CMS, such that it can be maintained be a set of persons in the future. ...

I have just found out that this problem does not affect all PDFs. But I have some (small) PDFs that definitively produce this problem and could provide them for a closer inspection.

I can verify the bug, but not the suggested work-around via -green-primary. I tried to place this option at various points of the command line, but with no effect on the resulting TIFF. It is correct that the effect only affects group4 coded TIFFs. My workaround is to open the files with IrfanView a...

I have a few older versions of the IM installer for Windows in backhand, but not exactly the one that you are asking for. The COM object is part of the standard installer package for Windows AFAIK. There is no archive for older precompiled versions, see http://www.imagemagick.org/discourse-server/vi...
