All right, the post about a patch being on its way had me thinking otherwise.
Thanks for the information though.

As I mentioned in my post, I tried with different versions, including the latest 7.x and latest 6.x. I uploaded a sample file here https://ufile.io/y40ao As you can see this is a GeoTIFF, so the missing tags in the output are 34264 (ModelTransformationTag), 34735 (GeoKeyDirectoryTag) and 42113 (GDAL...

Yes I know about quiet, but warnings are not the problem here.
The tags are removed in my case, as shown by the identify I posted for the input and output tiffs.

You mean that you have the warnings about unkown tags and still have them in the output ?

But isn't this a known tag ? identify shows the tag name.
The problem is with custom tags ("unknown field with tag" warning during conversion, "Tag 33550" in identify).

Sorry to up this old thread, but I have the same problem and cannot find aversion of ImageMagick that would preserve unkown tags. The relevant tiffinfo is : TIFFReadDirectory: Warning, 17_000737870_005092700_17.tif: unknown field with tag 33550 (0x830e) encountered. TIFFReadDirectory: Warning, 17_00...

I added it but AFAICT there is no difference. I thought that gs was the most expensive operation, but from what I see in Process Explorer it definitively isn't. I do see convert running on all cores at some point though, but again this is very brief and most of the time it is running in a single thr...

Yes, I never really benchmarked the command, but I believe that reading the EPS and expand it to a raster is the most expensive operation. And that is handled by GhostScript. BTW, since EPS are using a delegate, I checked in delegates.xml, and there is no dNumRenderingThreads option in the command l...

Ah, yes, GhostScript ! I forgot about that, thanks !
So if flatten & LZW compressed tif is multithreaded, should I see an increase in the number of threads used at the end of the conversion process ?

Hi all, I am using IM 6.9.3-8 Q16 x64 2016-04-10 (I know it's quite old, but I've had some problems trying to upgrade, I might start another thread on the subject). I run this command : convert.exe -limit memory 5000 -density 1600 -set colorspace RGB -background white source.eps -flatten +matte -com...

Isn't there a solution to this problem ? I really need to do this montage.
Thanks a lot !

I'm coming back with the same command. Adding -limit area 0 worked fine for most of the images, but for one batch that raises a windows error : http://img824.imageshack.us/img824/2116/erreurimagemagick.png C:\>identify -version Version: ImageMagick 6.6.7-2 2011-01-19 Q8 http://www.imagemagick.org Co...

I'll try this ASAP, thanks !

Hi all ! We are trying to run this command that tiles about 4000 images ( 600x600 pixels each) into a very large image, but it fails. montage tiles_*.png -geometry 600x600+0+0 --with-quantum-depth=8 -limit memory 1GB -limit map 2GB -tile 78x large.png The -debug cache gives me this information (last...

-layers merge works great, thanks a lot !

Hi all ! I am trying to overlay 3 PNGs in one command. They all have a white background that must be used as transparent color. They are also named with the same pattern : image_XXXXX_tmp.png I tried with this command, but one of the images does not appear in the final image : convert image_*_tmp.pn...
