Re: deskew

contrast-stretch looks at the histogram. When you crop, the histogram will differ from the original.

Re: convert jpg to RGB components

I am not sure what you mean. If you mean to separate the RGB channels from the image, then convert image.jpg -separate channel.png The result will be channel-0.png for red, channel-1.png for green and channel-2.png for blue. Or convert image.jpg -channel r -separate red.png convert image.jpg -channe...

Re: Missing delegate for "http"

I think your policy.xml file needs permission to do http: processing. There you will find <!-- <policy domain="delegate" rights="none" pattern="HTTPS" /> --> Uncomment and set the rights to read or read|write What do you get from convert -version on both systems in terms of delegates listed.

Re: Adaptive sharpen slow - any way to speed up?

You are using Q16 as per your listed information. However, the date of your version is 20170114, which is 2.5 years old (01/14/2017). You should see if there is an upgrade or patch to a current date. How many cores does your computer have. More cores means faster processing, generally. However, on s...

Re: Annotate worked in earlier versions

With regard to image rotation, some images contain EXIF meta data for the image orientation. Use -auto-orient to have them rotated properly. Font names only work if they have been entered into the type.xml file. This can be done using Anthony's script https://www.imagemagick.org/Usage/scripts/imagic...

Re: Adaptive sharpen slow - any way to speed up?

What is your Imagemagick version, Q level and platform? How big is your image? Do you have enough RAM for the process?

Re: Compare images and generate list of images which are not same

NCC does image normalization by subtracting the mean and dividing by the standard deviation 1) To insert an image inline in your compare command would need scripting and that is OS dependent. You would have to loop over each image and put the image into the command as a variable. 2) It would not mat...

Re: text list to individual images

Imagemagick 7.0.4.x is rather old. Perhaps upgrade first and report the full 7.0.x.x. version in the future. Sorry, I am not Windows user and do not know how to script for it. So I cannot help.

Re: Convert - Mogrify - Append - Same Filename | Windows IM7.0.8

These commands work for me. Try them and let us know.

Re: text list to individual images

What is your IM version and platform/OS. Your request would need scripting and that would be OS dependent (and not formally what this forum is about).

Re: Is it possible to compare 2 images and see the diff?

I do not use Magick.NET. But in looking at your code, you are using -compose difference -composite in command line, but using compare in Magick.NET. They are not equivalent. The output from compare is color coded over one of the two images. The output from composite, you color code the difference. Y...

Re: How delete rows from pictures?

I am not sure there is a simple easy answer. The line on the right can be chopped off by using -chop. Or use connected components to located the small lines and numbers and fill those regions with white. The diagonal line is much harder. The only thing that comes to mind is changing the black color ...
