Re: Converting colour profile oddity - help please

Okay, now I've got a decent internet connection... "-depth 8" is a setting, not an operation. It doesn't change pixel values. Instead, it affects what following operations do. "-depth 8" does affect the "-colorspace" operation, but I'm not sure how. Experiments show that for your image, "-colorspace...

Re: Converting colour profile oddity - help please

What version of IM? Does it have HDRI? On what platform (though that should make no difference)? Your image is too large for me to download, but I may be able to later today. As Fred says, using both "-profile" and "-colorspace" is usually a bad idea. These are two different systems for specifying c...

Re: Replace all occurance of an image with another one in a larger image.

Your links don't work for me. I get: Error 1011 Ray ID: 489af3e98db134b2 • 2018-12-15 18:25:26 UTC Access denied What happened? The owner of this website (schakal.ru) does not allow hotlinking to that resource (/tmp/from.png). Images are sent to stdout. Text messages go to stderr, so use "2>tmp.txt".

Re: Replace all occurance of an image with another one in a larger image.

That page tells you how to ask questions. You should say what version of IM you use, on what platform. You should link to an example screenshot and what you want to search for and what you want to replace it with. If you don't do this, we can only give vague answers. See the very similar recent ques...

Re: ImageMagick 7 - composite inconsistent color in output/print (need help)

I agree the scan of the print is different to the original. I have explained why, and what you can do to minimise this: use a colour-managed workflow, with ICC profiles that are specific to the printer/ink/paper, and the scanner. You also need to have an ICC profile for your computer screen.

Re: Placing image and joining commands

... it just places it over to the right and in the middle ... +append Well, yes, that's what "+append" does. See http://www.imagemagick.org/script/command-line-options.php#append Perhaps you want "-compose Over -composite" instead. I suggest you get the individual commands doing what you want befor...

Re: How to place image directly to the center?

The white strip on the left is 6 columns wide, not 5. We can shave first, crop and find the mimimum: f:\web\im>%IMG7%magick pic0.jpg -shave 2x2 -crop 4x+0+0 -format %[fx:minima*255] info: 0.921569 So the darkest channel value in those remaining 4 columns is 92.15% (which is 235 out of 255), so "-fuz...

Re: How to place image directly to the center?

[The upper red image...] Left white column is is a few pixels wider than right white column. Yes, because the left side starts off with a few columns of roughly white pixels. If you intend to trim them off, use a larger fuzz. Incidentally, where did these images come from? JPG is a very bad format ...

Re: How to place image directly to the center?

It seems to work fine, but I don't know what you intend. Set a different background colour to understand what is happening. Perhaps you intend the two images to be the same size. If so, you need "!" in the resize. See http://www.imagemagick.org/script/comma ... p#geometry

It is telling you there is no Null: in your image list. Compare your latest command to your original command. Why did you remove "Null:"?

I can't download your images, so I can't diagnose your problem.

Why are you still running "convert"?

Re: How to place image directly to the center?

To shave 2 pixels from all sides, use "-shave 2x2".

That page also gives the correct syntax for "-crop".

This is a message from a Microsoft program convert.exe, not ImageMagick.

For V7, I suggest you use "magick", not "convert" or "magick convert".
