Re: Convert not using multiple threads

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...

Re: Convert not using multiple threads

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...

Re: Convert not using multiple threads

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 ?

Convert not using multiple threads

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...

Re: Out of memory with very large montage

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...

Composite images with wildcard and transparency

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...

Re: Get image "Type" with identify ?

Oh OK you just meant extracting the information from the "verbose" output.
I can do that.
Thanks for your help guys !

Re: Get image "Type" with identify ?

Thanks for your answer.

%r gives me "DirectClassRGB".

That looks like a combination of the "Class" and "ColorSpace" fields from the -verbose output, but that's not what I am looking for.

Get image "Type" with identify ?

Hi all ! When I use "identify -verbose" on an image, I have a "Type" field that tells whether the image is Palette, PaletteMatte, TrueColor, TrueColorMate, etc... How do I get only this information with "identify -format" ? Thanks a lot ! Edit : Just to make the point clear... I have a huge bunch of...

Re: I don't understand how t oadd -flatten to this command

Yes the section of command line syntax was written when IM v6 first came about, and the key was making people understand that things should be done in operational order. What was not made clear is that READING IMAGES is an operation too. Indeed, that's the point. Furthermore, one needs a certain un...

I've read a lot of the "usage" pages, which are great, but the command line syntax remained quite obscure to me.
Thanks a lot for clarifying all this !
