Re: Identifying min-is-black Property Quickly

I love exiftool but it has one major drawback. It gets info from metadata - nothing less, nothing more. If there is chance that metadata in images is false, eg. because some software package doesn't know it should update relevate Exif fields *ehem*, you should consider identify. It is slower but get...

Re: Feathered mask

That's it! Thank you very much.

I thought this is something with -colorspace but put it in all the wrong places (outside of ()s ).

Re: Feathered mask

Thank you very much. But I have problem - mask is working great but red manipulation is broken.

Re: Feathered mask

Well, it's kinda obvious (although thanks for syntax). The real question was: how to create mask for pixels fullfilling condition:

Code: Select all

hue > 0.917 && hue < 0.083 && saturation < 0.10
without FX?

Feathered mask

I've refined command from my previous post to form: convert file.tif -channel H -fx "hue < 0.917 && hue > 0.083 && saturation > 0.10 ? r * 0.97 : r" +channel file-fx.tif But I have two problems: 1. -fx takes terribly long time to work, on big files it really adds up 2. It c...

Re: Using the "*" character: order of images

'*' is resolved by your shell, not ImageMagick. So, yes, it should be the same order as it is returned by 'dir p*.tif'. This order will be different on various systems, various shells etc.

Re: [SOLVED] don't grok -fx + reduce red tint in non red areas

Thank you very much. I've improved my command. Pure RGB path was nonsense, solution which works perfectly for me:

Code: Select all

convert file.tif -channel H -fx "hue < 0.93 && hue > 0.07 && saturation > 0.15 ? r * 0.98 : r" +channel file-fx.tif

don't grok -fx

Hello, I'd like to reduce red tint in areas where red color isn't visually dominant. I've got and idea to play with something like: abs(b-g) > 0.1 && r-max(b,g) < 0.1 ? r*0.9 Two questions: - how to implement it with -fx ; for now it responds convert.exe: unable to parse expression `r' @ err...

Re: -flatten command not working as equivalent to photoshop on Multilayered images

OK. This was a problem with Alpha channels which hit me in the past so I played with PS a bit. IM interprets alpha channel/mask just the other way about than PS. You can see it in PS when you invert mask 'Color Fill 1'. After this IM command works like a charm. I don't know how force IM to invert on...

Re: IM7.0.2-9 is not using available resources

@Fred

After snibgo comment I used non-HDRI version of Q8 so this is not the case. I would prefer stay with gaussian. IMO it generates better, smoother effects.

BTW - thank you very much for highpass filter used in this command :)

@magick

Thank you.

Re: IM7.0.2-9 is not using available resources

In my past experiences Q-change consequence was significant change in RAM usage but minor in execution time but I will retest it.

Re: IM7.0.2-9 is not using available resources

Yes, thank you. That was it.

Although even when IM7 uses all 12 threads it is significantly slower than IM6. The same task (processing of 10 big files) IM6 did in 7m:53s while IM7 did it in 16m:51s.

This is similar to problem reported (and solved for IM6) here: http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=26992 IM7 is not using available resources. When processing big file magick uses 1 thread, 8 processes and on average about 8% of CPU (as reported by Windows resource mo...

Re: im7: -compose Colorize

Thank you all. Unfortunately probably old bug reared its head - but about that in separate thread.
