Re: Hash patterns and bloctches

I tied the suggestions but was not able to get much improvement. Any other ideas?

Re: Hash patterns and bloctches

Im aware of your excellent notch script. I gives a cleaner result than the basic no-op operation. Currently I have v6.9.2-6 Q16 HDRI x64 installed on Windows 10.

Hash patterns and bloctches

I decided to revisit this image. http://i.imgur.com/Dx1GDI3.jpg I can remove the hash pattern by using a no-op command: convert input -filter lanczos -distort resize 100% hash_removed.png http://i.imgur.com/wFwVZUE.png However this introduces bloctches. Previously I discovered I could cancel out the...

Re: Notch on Cygwin -Bug report

That was quick! :shock:
Unfortunately I see the same behaviour with the updated script.

Notch on Cygwin -Bug report

Probably needs confirmation but the -R and -B parameters seem broken. Acts as if all -L -R -B -U parameters are at 0. -L and -U work as expecterd individually and in combination however.

Re: -Distort on scanned mag. picture and colorspaces

Testing a multitude of colorspadces was for the sake of finding a different result. I chose the smooth Quadratic filter to make it easier to focus on the blotches and how they blend with the rest of the image. What do you think about my result vs FFT notch? http://i.imgur.com/qNXUdTr.png http://i.im...

Re: -Distort on scanned mag. picture and colorspaces

I've been reluctant to try out anything labeled alpha, and I've been unable to find a HDRI build of 6.8.X for Windows. I'm happy to hear that 7 works well! I really should install and learn cygwin, then try building IM myself. Time is against us all. I don't immediately have any ideas for improveme...

What seems broken when using "convert" in IM 7? I am sure the developers would like to know so as to fix it.

Re: -Distort on scanned mag. picture and colorspaces

Welcome. magick, does that mean you are using the version 7 alpha? Platform? I have been reading your posts but I honestly have nothing useful to add about filters. I do know a reasonable amount about colorspaces though. Thanks! I'm using the IM7 build for Windows since it comes with HDRI, haven't ...

-Distort on scanned mag. picture and colorspaces

Just doing a tiny rotate operation on a scanned magazine photo, noticed some curious curious things about how input colorspaces interact with the halftone pattern. The basic command is: magick imput.jpg -colorspace rgb -filter Quadratic -distort SRT -0.22 -colorspace sRGB output.png RGB, XYZ, ScRGB,...

Windows batch files for Nicolas resmpling filters

I'm putting together a series of Windows batch files for state-of the art resampling in IM based on Nicolas guide: http://www.imagemagick.org/Usage/filter/nicolas/ Please let me know if it's a reasonable selection for typical resampling tasks or if the parameters need to be updated.

Re: delegate library support

Another windows user here, dying to try Fred's 'notch' script on various problematic images.
Being forced to compile from source is disconcerting to me as I have no previous experience with compilers.
Any chance there's a special build available with FFT support built-in?
