Re: Does something like this exist?

For example, if i were to apply a 50% black threshold to the color (50, 200, 200) it changes it to (0, 200, 200). How could I make it so that if any of the channels are below 50%, then set color to (0, 0, 0)? First, you need to describe what you're doing by posting some actual examples of your scri...

Re: Trim image and output trim amount

Allows to get me the untrimmed image's center within the newly trimmed image. You can also get the trim information without actually doing the trim with a command like this... magick input.png -set page %[@] output.png If the output format supports it, like PNG and TIF, the paging information of th...

Re: Hi guy, anyone else here?

I read on the tutorial that I can use the clone command, but I don't know how to use it in this case. With your version you can use multiple instances of "( +clone )" as fmw42 suggested. Another approach is to expand the viewport to 30 times the width of the input image, tile the input into that vi...

Re: Crop & Rotate

I want to save the new file with an appended as "-Modified.jpg" just not sure of the syntax. ImageMagick can hold the input file name as a variable to use as part of the output file name. Try something like this... magick input.jpg -set filename:f "%[t]-Modified" <do some other things here> "%[file...

Re: Compositing thousands of images

Thank you - that worked nicely and was very easy to implement! The only challenge i have is that some of the images i'll be creating involve an insane number of these smaller images (250,000 to be exact) and while this new code does work it takes a rather long time. I don't know much about managing...

Re: Need help?

Is such a thing possible? Has it already been done? You need to provide a lot more information, like what version of IM you're using, what platform you're working on, whether you're running it from a command line or script or whatever. Provide some examples of things you've already tried. Read the ...

Re: Compositing thousands of images

I have full control over the script that creates the txt file so this can be changed in any way (e.g. if we needed to have a name for the image instead of a path etc). With the option to write the list of input images any way you want, you might consider doing something like snibgo 's suggestion ab...

I'm wanting to read in the small image filepath from this txt file as well (which i can do no problem) but as it's the same 5 images that get used over and over again Im thinking they can be instantiated once and then reused (as per Point 8 on https://stackoverflow.com/questions/28704984/how-to-spe...

I just tried that and sure enough, the AR is not 1. Thanks, I'll use this method for now.

Re: how to include only certain areas of an image

Is there a way I could do the above using some other colour apart from black ( I currently using "rgba(0, 255, 255, 255)" and it would be great if I could stick to that) ? You will speed the command by reading in the input image only once, then process clones to extract your individual boxes. As wi...
